Heating radiators, like it or not, are very often an integral element of the interior of premises, which means they require certain decoration and regular maintenance. In order for heating radiators to look neat, to serve trouble-free for as long as possible, and for the paint layer to adhere to them reliably, without cracking or peeling, despite high temperatures, it is necessary to use special heat-resistant paint and varnish compositions for these purposes.
Which paint for radiators is best to choose? This question arises for all homeowners who have decided to update old heating appliances or are preparing to install new ones purchased unpainted. To understand what you need to pay attention to when purchasing paint and varnish materials, you need to consider the requirements for them.
What criteria must paint for heating radiators meet?
Compositions for painting radiators and heating pipes are somewhat different in their parameters from conventional paints, so it is worth familiarizing yourself with their main physical, technical and operational characteristics, which experts recommend paying special attention to.
- First of all, the paint must be safe for the residents of the apartment or house, that is, it must not emit toxic fumes during the entire period of operation. Therefore, when purchasing, it is necessary to study the composition of the paint and its compliance with accepted standards and norms. Imported paint European manufacturers, whose brands are in large assortment presented on Russian market, must correspond European standards, and domestic products - to the standards of current GOSTs. If the packaging contains a link not to standards, but to some mysterious specifications (technical conditions), then this can be considered an “amateur activity” of the manufacturer, and it is better to immediately discard such paint - its compliance with safety standards is not guaranteed in any way.
- The heat resistance of the paint should not be lower than +80 degrees, otherwise it may crack, begin to peel off or turn yellow. Moreover, this indicator should be considered the minimum acceptable - it is better if it is even higher.
- It is desirable that the paint composition be quick-drying - this factor will significantly speed up the work, since the paint is usually applied in two layers.
- The anti-corrosion properties of the paint will protect the surface of the radiators from external aggressive influences. This is usually taken into account when producing coating compositions metal surfaces.
- Some paints emit a sharp effect before they dry completely. bad smell– they can be chosen only for those rooms that can be thoroughly ventilated.
- Moisture resistance for radiator paint is necessary to be able to carry out unhindered wet cleaning using detergents.
- The thermal conductivity of the paint layer must be high enough, otherwise it will reduce the heat transfer from heating devices.
Types of compounds used for painting heating system appliances and pipes
For painting radiators and heating circuit pipes, paints are produced on different bases. Each of them has its positive and negative sides, and they must also be kept in mind so that these points do not turn out to be unexpected.
Varieties based on base and component composition
So, heat-resistant paints can be oil-based, alkyd, water-dispersion (acrylic or silicone) and powder.
Oil paints
They are made on the basis of various organic oils, and not so long ago this was practically the only option for painting radiators. Such paints have high hiding power, creating a dense and durable layer on the surface of the batteries that is resistant to various mechanical influences and can withstand high temperatures.
However, in our time they have practically been abandoned, since many other compositions have appeared that do not have the significant disadvantages inherent in oil paints:
- These paints have a rather unpleasant specific odor, which not only accompanies the process of painting and drying the surfaces, but can also appear during the operation of the batteries, when the radiators are very hot.
- The density of the layer formed on the radiators significantly reduces the useful heat transfer of the sections.
- There is a certain difficulty in applying the composition on such a base - unlike other paints, it is difficult to apply oil paints in a perfectly uniform layer.
- If a layer is applied too thick, the paint may begin to crack and peel during operation of the heating appliances.
- Over time, surfaces lose their shine and begin to turn yellow.
- Colorful coating on oil based does not protect the metal well enough from corrosive processes and quite often you can see rust appearing on the surface of the batteries.
- Oil paint It is characterized by the longest period of complete drying, and when applying it it is very difficult to avoid the formation of smudges.
In a word, numerous disadvantages clearly outweigh the advantages (the main one of which is the affordable cost). Name this paint a good option for heating radiators - difficult.
Alkyd enamels for radiators
Heat-resistant alkyd-based paints consist of a dispersion of pigments and special additives, sealed in pentaphthalic or glypthal varnish. They are quite popular, as they have a number of advantages that make it possible to reliably protect the surface of radiators from external negative influences, as well as give them a neat and aesthetic appearance.
Almost all heat-resistant alkyd enamels can withstand the highest temperatures that can even theoretically occur in the heating circuit - this operational parameter is usually indicated on the product packaging. The surface painted with them has perfect smoothness and even gloss; the paint layer does not turn yellow or peel over time.
Prices for enamel for Alpina radiators
Alpina radiator enamel
Alkyd enamels have fairly high wear resistance and are produced in a variety of colors, which allows you, if desired, to choose the desired color to match the overall interior of the room.
However, despite the listed advantages, such compositions also have their disadvantages:
- Alkyd-based paints that contain white spirit have an unpleasant, pungent odor. It not only lasts for several days after painting, but can even appear at first when the radiators are heated too much;
- A sufficiently long waiting time for each layer to dry can increase the period of painting work to several days.
Alkyd enamels are also available in the form of aerosols. However, it must be said that covering batteries in this way is not as simple as it might seem at first glance.
Acrylic heat-resistant enamels
This type of paint and varnish composition is widely used for painting elements of heating systems, since the dried layer makes the surfaces perfectly smooth and even, even resembling plastic in appearance. Acrylic paints have virtually no odor, both during the painting process and during operation of the heating system.
When purchasing acrylic paint, you first need to study the packaging, paying attention to the manufacturer and the purpose of the composition. Special attention- on the temperature that the paint can withstand, since not all acrylic coatings are designed even for 80 ºС, not to mention higher values.
Acrylic paints dry quickly - the time for them to set and completely dry is indicated in the instructions for use, and can range from ten minutes to an hour and a half for the first stage, and five hours until one layer is completely ready. In order for the coating to be of high quality, it is necessary to protect the painted batteries from moisture during the entire drying period.
Acrylic paint solutions have a medium-thick consistency of sour cream, they do not spread, and practically do not leave smudges. The paint must be applied to the cleaned, primed surface in two layers, otherwise the desired effect will not be obtained. A significant disadvantage of acrylic compositions can be considered their low resistance to external mechanical influences, including abrasive loads.
Silicone paints for metal
High-quality silicone compounds have the property of maintaining their characteristics even when heated to critically high temperatures, so paint based on it will withstand any heat that may occur in the heating system. Paints are made on the basis of silicone resin, which is mixed with organic or aqueous solvents. After the applied layer dries, it acquires a semi-matte shine.
The silicone compound can be applied to an unprepared metal surface. It is resistant to mechanical stress and abrasive loads, and therefore very durable.
The only significant drawback of this paint option for radiators is its high price, so it is not as popular among consumers compared to other compositions.
Powder paints
This type of paint consists of a special pigment powder and special binding additives. It can be called the most durable and durable coating for heating radiators, but using it in an apartment will not work.
An obstacle to self-painting with a powder composition is the technology itself, that is, the creation of the necessary conditions for this process:
- Firstly, you need special equipment with which paint will be sprayed onto the surface of the radiator, and it is very expensive.
- Secondly, you need a source of precisely calibrated constant voltage to apply the composition - the powder is given a positive charge, and the surface to be coated is given a negative charge.
- Thirdly, painting must be carried out in a special chamber, where, after applying the composition, certain temperature regime. To ensure the polymerization process of the applied powder dye, the surface of the radiator must be heated to a temperature from +170 to 350 degrees (the specific value depends on the characteristics of the composition).
It is clear that it is absolutely impossible to achieve such conditions at home, so this type of painting is most often produced in production conditions. If you want to paint your radiators with a powder composition, you can find a car repair shop that specializes in body work and is equipped with a set of equipment for painting cars using exactly this technology.

Matte and glossy paint
Heat-resistant paint, like any other, is also divided into glossy and matte. Which one to choose will directly depend on the quality of the radiator surface.
So, for example, for old-style cast iron batteries (type MS-140), which have rough outer walls, it is best to use glossy paints– their shine will slightly hide surface unevenness. In addition, the glossy layer is easier to clean from contaminants formed on them and remains in its original pure form longer.
Matte paint, on the contrary, will highlight flaws in the radiator surface. In addition, it will not hide the porosity of the surface, which for this reason will be more susceptible to contamination. Therefore, if white matte paint is chosen for cast iron batteries, it will quickly acquire a gray tint. It is problematic to wash the matte surface, and getting rid of the unpleasant gray color will only be possible with new painting.
For perfectly smooth surfaces of modern heating radiators, any option in terms of paint gloss level is acceptable.
One more nuance. Sometimes manufacturers add fine chalk to the paint to achieve a matte effect. However, what is good for walls and ceilings is absolutely unacceptable for metal surfaces of radiators. If this ingredient is indicated in the composition of the paint, then it is better to refuse such a purchase, since the painted surface of the battery will certainly turn yellow over time, and quite quickly. The best option for matte paint would be a composition that includes titanium dioxide in its composition, since it will not change its original color throughout the entire period of operation.
A brief overview of popular compositions for painting heating radiators
Of course, any home owner, when undertaking a renovation, wants to do it once and for a long time, so as not to return to the problem of painting radiators in a year or two. This means that it would be advisable to purchase a high-quality specialized composition; even its price will be slightly higher than that of ordinary paint.
The table below presents some well-known brands of the most commonly used alkyd and acrylic based paint compositions, with a brief description of their characteristic features. Perhaps this information will help determine the choice of the optimal material.

The information presented above leads to the conclusion that there is no shortage of quality paint compositions for heating radiators. In the assortment of stores you can find products famous manufacturers, and it is best to choose it, since such materials have stood the test of time and have earned their popularity due to their impeccable quality and durability. Of course, branded products have more high price, but it’s better to pay once and forget about repair work for several years than to spend money, time and effort on painting appliances and heating system circuits every year.
How much paint will be needed to paint a radiator?
Paint manufacturers always indicate its average consumption. It would seem that everything is simple. But if you paint, for example, the front surface of a panel heating radiator: determining the required area there will not be difficult. It’s a different matter if sectional cast iron “accordions” are to be painted.
The technical characteristics of heating radiators often indicate their total area– if desired, this parameter can also be found on the Internet. But in order not to force the reader to waste time on this, a special calculator was compiled that will help carry out calculations very quickly and accurately.
- The calculator takes into account the parameters of the most common cast iron radiators of the “MS” and “ChM” series of various modifications. In addition, it is possible to simultaneously take into account additional material consumption if you also plan to paint the supply and return pipes suitable for the radiator.
- Paint consumption for calculations was taken as average, by type - oil, alkyd PF, acrylic and silicone. Despite some differences between different brands of coatings, the approximate consumption is still at approximately the same level. In this case, the condition is taken into account that the coloring is white.
- Different manufacturers do not have uniformity in measuring flow rates - volumetric values are indicated in ml/m² (or vice versa, m²/l), or by weight (kg/m²). It is still more objective to judge by weight equivalent (as is customary in construction planning), since the volume of any paint can be increased by adding a solvent, but its hiding power will not increase because of this - it depends precisely on the mass of the material. Therefore, for a unified approach, the final value will be given in kilograms - on the factory packaging of paints, in addition to the volume, the net weight of the packaged paint must also be indicated.

An integral role in the arrangement of any living space is invariably played by such important communications as the heating system. The devices that are part of it can not only heat the air in the room, but also form part of the interior, while a well-designed radiator will become a real decoration of any living area.
However, old batteries with peeling paint are unlikely to be able to decorate the house in any way, so the owners find a solution to this problem by replacing old equipment with new ones. This method is quite effective, but also very expensive. Therefore, it will be a much more reasonable decision in terms of savings.
It is worth noting that in the process of deciding what paint to paint the radiators with, you should opt for special compositions designed specifically for such structures. Their use will protect the surface of the radiator from corrosion and provide the unit with an aesthetic appearance. If previously it was customary to cover the functional parts of the heating exclusively with white compounds, today the materials for painting have a wide variety of shades, so choosing the option that will best suit the interior of the room being furnished will not be difficult.
What determines the choice of paint for batteries?
To figure out which paint is best for painting batteries, you should remember that the quality of the composition used directly depends on the final result of the work.
- resistance to high temperatures (at least 100°C);
- resistance to aggressive environments;
- wear resistance;
- absence of any harmful released substances.
These include:
- Acrylic enamels. Their production is carried out using solvents of organic origin, as a result of which during the drying process a characteristic and not very pleasant odor appears. However, such paints have a glossy shine that will not disappear even after many years of use.
- Alkyd enamels. Such compositions are very resistant to high temperatures and are wear-resistant. In addition, you can always choose the desired shade, since these paints are available in a rich range of colors. The main disadvantage of these enamels is the unpleasant odor, which not only lasts several days immediately after painting works, but may also appear again when the radiator heats up too much.
- Water-based paints. This option is considered optimal among consumers, since this odorless paint for batteries dries very quickly (more details: ""). However, when choosing such a composition, it is very important to pay attention to its packaging, which must include information about the possibility of applying such paint to elements of the heating system. High-quality, odorless paint for radiators cannot be cheap.
Thus, we can say that the only odorless battery paint is water-dispersion, so it is this material that you should pay special attention to.
Less often today, oil-based paint is used, since such a composition has become obsolete over time and has given way to more modern paint and varnish products.
Preparation before painting radiators
It is important not only to decide which paint is best to paint the batteries, but also to carefully prepare the desired surface for processing. In this case, an important fact is that they themselves preparatory activities take much more time than the process itself.The procedure should be as follows:
- The surface of the radiator must be thoroughly cleaned by removing old paint and cleaning the areas where rust has appeared. Dust and dirt should also be removed with a cloth.
- Next, you need to apply a solution to the battery to wash off the old coating, and then cover it with a film to soften it. Next, the paint can be easily removed using a construction spatula or a grinding machine equipped with (read: “How and how to remove paint from a heating radiator - means for removing old paint before painting a radiator”).
- After this, the already cleaned surface is sanded with sandpaper and degreased using any solution with a small amount of alkali.
- A primer with anti-corrosion properties is applied to the already cleaned surface, which not only prevents the appearance of harmful formations, but also increases the adhesive properties of the paint. It is best to use an alkyd primer for these purposes.
The process of painting a heating radiator
Having finally decided on what paint to paint the radiators with, all actions should be performed in accordance with the following order:- Initially, you need to protect the floor from contamination by covering it so that paint stains do not fall on it. Unnecessary paper (for example, old wallpaper) or fabric is perfect for these purposes.
- Then you should choose brushes that have soft bristles. In this case, one of them should have a straight shape, and the other should be curved so that paint can be applied to the most inaccessible areas of the radiator.
- You must first apply the coloring composition at the top of the battery, gradually moving towards its bottom. At the same time, do not forget that you need to paint all areas of the radiator, starting with internal floors and ending with external ones. This is done in this order so as not to accidentally stain your clothes or hands. After the first layer of the composition has dried, you need to apply the second. Experienced craftsmen recommend: regardless of what paint to paint cast iron batteries or batteries made of another material, it would be much more correct to apply two thin layers rather than one thick one, since in the first case it will be possible to ensure uniform paint coverage. Read also: "".
By performing all the above steps in exactly this sequence, you will be able to achieve a perfectly flat and smooth surface of the radiator, and the applied paint itself will last a very long time (read also: " "). The main thing is to choose the right composition that will be most suitable for a particular heating battery.
If necessary, you can always study various photos color options for these devices to the best way choose the desired color scheme for yourself.
Tips for painting radiators in the video:
How to paint a heating radiator? - Those who have old cast iron “accordions” worry about this question literally every 2-3 years. Sometimes people think about this when, during ongoing repairs, they suddenly discover that the color of the radiator does not fit into the color concept of the room at all. Every year there is an assortment on the shelves of construction stores paint and varnish products increases and it becomes increasingly difficult to make the right choice. In this article you will find all the necessary information about what paint to paint radiators over old paint, how to do it, and whether this decision is always the right one.
- It is not advisable to paint modern aluminum and bimetallic batteries. Initially, they are painted at the factory with durable powder paint, which, thanks to the peculiarities of the technology, lies perfectly evenly. If you decide that the original color of the radiator (usually white) does not suit the interior of the room, and you want to repaint it, then you are unlikely to be able to achieve the same perfectly even coating. Even if you remove the battery and paint it horizontally. In addition, an additional layer of paint will reduce heat transfer, which is a significant disadvantage for regions with harsh winters.
- It is not advisable to paint plate radiators, especially those with a large surface area. They are installed in houses where there is a network with increased internal pressure. They have low convection but high heat transfer. As for our question, due to its design, it is difficult to properly paint a heating radiator of this type, especially with a brush. If this is really necessary, then you will have to remove it, clean it thoroughly (which is very difficult) and paint it in a horizontal position with a spray gun or car paint in the form of a spray. But even this way you may not achieve a perfect application. There may be missing areas in hard-to-reach places, because the elements of the plate radiator are located too close to each other.
- Convectors and pipes with fins (especially with frequent aluminum fins) are not painted, since painting can negatively affect their heat transfer. The design of the convector, in addition to the heat source, includes a removable casing. It can be painted to enhance the overall look.
- It is recommended to paint cast iron batteries. This is not difficult to do, different paints are suitable and they do not affect the heat transfer. The choice of colors is huge.
- It is possible to paint steel panel radiators. But there is a nuance here - it will not work to evenly cover the surface of the battery with a brush. You will have to use car paint in a can, and it is advisable to paint in a horizontal position.
Important! In order to bring the battery as close as possible to the desired color and color scheme of the room, it is recommended to use decorative panels. They are sold in construction stores and online stores. They can be made of wood, metal, plywood, plastic and even glass. There are such screens different forms, colors, sizes. They can be covered with figured carvings, patterns, photo printing, etc. So the choice is great, and you can choose them for any, even the most sophisticated interior.
- To paint a cast iron radiator, use straight and curved soft brushes, no more than 5 cm wide.
- To paint a panel radiator, use a small-width foam roller.
- Paint in cans or spray.
- Paint bath (if the paint is not aerosol).
- A special paint remover (if you decide to get rid of old paint chemically) and a metal spatula.
- A drill with a metal brush attachment for cleaning the battery from paint residues.
- Solvent.
- Gloves, safety glasses, respirator or gauze bandage, protective clothing.
- Newspapers, oilcloth, cardboard, masking tape to protect surfaces.
- Rags.
What paints are suitable for painting a radiator?
During the repair process, we think about how to paint the radiator without smell, without streaks and drips, so that the paint dries quickly and the beautiful appearance of the device is preserved for a long time. At the moment, there is no such ideal paint yet. However, there are several options to achieve optimal results.
The following may be suitable for painting a radiator:
- water-dispersion and water-based paints;
- alkyd enamel and auto enamel;
- acrylic paint;
- oil;
- silicone-aluminum paint;
- silverfish
Let's look at each option in more detail.
Oil paint
Regarding this type of paint, let’s immediately say that theoretically it is, of course, suitable. But in practice, it is almost never used for painting batteries:
- Its biggest disadvantage is that it takes a very long time to dry. This process can take up to a month; you must admit, it is not very convenient.
- In addition, oil paint has a rather unpleasant odor.
- It is difficult to paint the surface evenly, without drips and sagging.
Important! In view of such significant shortcomings, it is recommended to choose another option for these purposes.
Water-dispersion and water-based paints
Water-dispersion paint is made on the basis of polymers and water dispersion. Its main features:
- It is moisture resistant and can be washed.
- Diluted with water.
- Mainly available in white.
The water emulsion is made on a water basis, and it:
- Can have many colors and shades.
- Not so resistant to abrasion, it can slowly wash off upon contact with water.
- Can be diluted with solvents (eg white spirit).
Important advantages of this type of paint are:
- their environmental friendliness and safety;
- no chemical odors during application;
- ease and simplicity of painting;
- possibility of tinting;
- wide choose tools for application and affordable cost.
Important! The only negative is that before painting you must prime the surface, otherwise the water in the composition will cause rust.
Alkyd enamel and auto-enamel
Alkyd enamel is one of the best options for painting a heating radiator. She behaves well high temperatures(withstands up to 100 degrees), with temperature changes, is resistant to abrasion and has many colors.
Regarding its capabilities:
- This type of paint is sold everywhere and is relatively inexpensive. This is the familiar PF-115 and its imported analogues (produced by the brands ACE, Dulux, Sigma Coatings and others).
- A significant disadvantage is the persistent chemical smell, which disappears for a long time after applying this paint to the battery.
- In addition, low-quality enamel may turn yellow over time.
Auto enamel also has a persistent unpleasant odor, so the room will then have to be ventilated for a long time. There are other application nuances if you need to paint a heating radiator:
- Applying paint from a can is quick and easy, but this, of course, requires skill so that the paint layer applies evenly.
- This application may leave unpainted areas, and it is also necessary to carefully protect all surfaces surrounding the radiator from splashes.
- Auto enamel has a glossy shine; it will highlight and highlight all surface irregularities.
Acrylic paint:
- Acrylic paint It is also water based.
- It has practically no smell and has an affordable price.
- The base base is white, but if this color doesn’t suit you, you can tint it in any other shade.
- The temperature limit of acrylic paint is +80 degrees - this is quite enough for average radiators.
- It dries quickly. It takes less than a day to apply 2 coats and have it all dry.
- It does not turn yellow over time, but also requires preliminary priming in order to avoid rust.
- After drying, acrylic paint forms polymer coating, which is wash-resistant.
Silicone-aluminum paint:
- It fits perfectly on any surface, forming a dense layer that contracts and expands with the metal.
- It can withstand temperatures up to 500 degrees, does not require preliminary priming, is easy to clean with any means and does not lose its visual appeal for a very long time.
Important! This paint is one of the most expensive. Another disadvantage is the pungent odor, which takes a long time to dissipate.
Serebryanka
Known since Soviet times. Its modern analogues are on the shelves of hardware stores. For example, heat-resistant paint BT-177.
How is it different:
- It consists of varnish mixed with aluminum powder.
- Silver grass is inexpensive, but also has an unpleasant odor.
Color selection:
- If you just want to update the appearance of the radiator without significant costs, then paint it white. White and silver are classics of the genre.
- If you want the radiators to be inconspicuous and fit into the decor, you can paint them to match the walls.
- In a children's room, the radiator can be made part of cheerful interior- cover it with bright paint or even make the sections multi-colored. You can apply patterns to the batteries with a brush by hand or using a stencil. It is possible to decorate the radiator using decoupage.
You already know what paint to paint radiators with, now let’s get down to the process itself. It can be divided into two stages:
- preparation (cleaning off old paint);
- applying paint.
Cleaning
Ideally, for proper cleaning, the radiator needs to be disconnected and the remaining water drained, since getting from the back side will be difficult. We will skip how to clean the battery from dust and dirt; everyone can handle this without additional advice. But there are several ways to clean old paint.
Method No. 1
The simplest and least labor-intensive method is to use a special remover. This chemical is sold in all hardware stores. But it is suitable for processing only cast iron radiators, since cast iron is inert to this substance.
Procedure:
Method No. 2
The second cleaning method is carried out using a hair dryer or gas burner.
Important! This method is not suitable for cast iron, as the process will take a long time and will be ineffective.
Procedure:
- The essence of the method is to use a device to heat a layer of paint to high temperatures, and then scrape it off with a spatula or a stiff brush without waiting for it to cool.
- It is advisable to carry out such work outdoors, so, of course, the battery must first be removed. If this is not possible, protect the surrounding surfaces with plywood and open the windows.
Important! This method can damage the gaskets in the radiator, so be prepared for the fact that they will have to be replaced with new ones.
Method No. 3
One more thermally is the treatment of batteries using a fire. The old “old-fashioned” method is labor-intensive, but it allows you to clean the battery not only outside, but also inside.
Procedure:
- Remove the radiator, unscrew all plugs and other parts.
- Disassemble the battery into sections using a radiator wrench (the sections are connected by nipples with oppositely directed threads).
Important! If this does not work out right away, then you can do it after firing.
- Make a good fire in the yard and put a radiator in it. Keep the fire going for about an hour, longer if possible.
- After removing the battery from the fire, clean it with a wire brush; this process will be easy and quick.
- After this, tap each section with a mallet to shake out all the rust that has accumulated over the years from the internal channels.
- Now all that remains is to reassemble everything using new rubber gaskets.
Important! Gaskets can be cut from an unnecessary car inner tube.
- Wipe the radiator from dirt and degrease.
Method No. 4
You can also use the mechanical method:
- Place an attachment on the drill (grinder) - a metal brush or an emery wheel.
- Treat the surface of the radiator.
Important! The disadvantage of this method is that many places are difficult to reach with a tool, so the work will have to be completed manually, using a stiff brush and sandpaper.
- As in previous methods, the surface should then be cleaned of debris and degreased.
Painting
When asked whether it is possible to paint heating radiators while hot, experts answer in the negative, because most paints will not adhere well to hot battery. It is better to paint outside of the heating season. If there is no way out, then paint quickly, without putting a lot of paint on the brush and immediately blend it with a thin layer. Or turn off the supply of boiling water to the radiator and wait until it cools down, then paint.
Important! During the painting process, remember to protect your eyes, hands and respiratory system from paint splashes and toxic odors.
After cleaning and degreasing, we proceed to the most important thing - painting. The procedure will depend on the type of dye chosen.
Acrylic and water emulsion
If your choice falls on acrylic or water-based paint, the radiator should be primed with an anti-corrosion compound, otherwise rust will appear over time.
Important! There are paints on sale that already have primer added to them.
Paint from a can
If you paint the battery with spray paint, then the technology is as follows:
- Start with hard-to-reach areas and then move on to front part.
- Move from top to bottom in a zigzag motion, without staying in one place, otherwise the layer will lie unevenly.
- It is recommended to cover the surface with two layers, so after the first has dried, proceed to the second.
Important! You can take the radiator to a service station for painting, where specialists will do it professionally.
Using a spray gun
Painting with a spray gun occurs in the same way as in the case of aerosol paint.
Important! To reach all areas, it is better to paint the battery while it is removed.
Liquid solutions
If you paint with liquid paints, then protect the surrounding surfaces with oilcloth and newspapers:
- Pour paint into a paint tray and use an angled brush to cover all interior and hard-to-reach surfaces first.
- After this, use a straight brush to begin working on the front part, moving from top to bottom.
Important! Take a little paint on the brush, the layer should be thin, otherwise drips will form.
- After the first layer has dried, cover with the second. Two layers are usually enough.
Important! Acrylic paint and water-based emulsion dry quickly and without much odor; you can finish it in a few hours without any problems. But alkyd enamel will dry for more than a day and emit an unpleasant odor for a long time, so we recommend painting the radiator in the summer, when it is possible to open the windows for a long time.
That's all the wisdom regarding the choice of paint for a heating device and the process of applying the dye itself. Using useful information from the article, you can do everything correctly and with minimal losses. You can be sure that after successfully updating old battery, the interior of the room will improve.

What kind of paint should be used for batteries?
A feature of any battery is that during operation it always heats up to a high temperature. Of course, the degree of heating depends on the temperature of the coolant and other additional factors. Regardless of whether, along with cast iron, steel or non-ferrous metal, the paint that is planned to be applied to the heating device will also heat up.
And so that the paint for heating radiators does not “please” with an unpleasant odor, harmful substances released into the air, as well as loss of its solidity, it must:
- withstand high temperatures;
- do not contain toxic substances;
- do not emit an unpleasant odor when heated;
- be resistant to aggressive environments and abrasion.
Types of dyes for batteries
Many types of paints, or rather individual representatives of these types, meet the above requirements. After all, most paints are designed for temperatures below +80 °C. Therefore, manufacturers produce special modifications of their products.
In general, painting batteries yourself can be done with the following types of paints:
- Acrylic enamels. They are based primarily on organic solvents. This feature causes the release of a solvent odor during the application of the acrylic mixture to the battery. However, once it dries, the smell becomes history and the room is left with a radiator with a nice glossy shine. This shine lasts for many years.
- Alkyd enamels. They are known for their excellent resistance to wear and high temperatures. The range of colors of these enamels is very large, so many people choose such paints. These paint solutions also emit an unpleasant odor as they dry. It can also be felt in cases where the heating radiator gets very hot.
- Water-dispersion paint. Many experts note that such paint for radiators is optimal. This is because it does not upset the nose with a specific smell, and the drying time is very short. True, not every water-based mixture is suitable for batteries. Only those that have the appropriate designation on the packaging are suitable. Its color can be any.
- Oil paints. They were very popular in the past. Known for emitting a solvent odor upon drying and long curing times.
It is worth adding that radiator paint may contain elements that resist corrosion and improve adhesion (they are constantly used in primers). Such mixtures have different colour, do not require primers or cleaning the radiator from corrosion.
At least that's what the manufacturers note. In practice, it is better to remove rust from the heating device and use a primer. The processes are lengthy, but the results are reliable. This is often noted in different videos.
Applying paint to a heating device
This process seems quite simple, but it requires correct execution. Heating radiator painting includes next steps:
- Removing old paint.
- Removing corrosion.
- Treatment with degreaser.
- Applying primer.
- Do-it-yourself application of several layers of dye of a certain color.
The first four points are preparatory.
Features of preparation
There are two ways to remove a layer of old paint:
- Mechanical.
- Chemical.
The first involves the use of a spatula or a round metal brush attached to electric drill. Using a spatula requires physical effort as you need to move it with your hands. Moreover, it will take quite a long time to wash off the paint. This must be taken into account when calculating the total painting time. The disadvantage of this option is that it is difficult to reach the bottom of thin cracks.
A round metal brush attached to an electric drill is a more versatile method. It is capable of treating almost the entire radiator area, including many hard-to-reach places. In this case, the work time and physical effort spent will be very small. Most people like this, including those who calculate the repair time and shoot a video of the process.
The chemical method involves the use of special solvents or fatty acids. They treat the entire area of the battery and cover the treated surface with film. Then they rest. The duration of rest is indicated on the packaging. It may be different. During this time the paint becomes soft. Of course, it does not slip (which would be very good), but its removal with a spatula, a grinder or a wire brush becomes very easy.
It is worth remembering that solvents emit substances harmful to the body. Therefore, when using a chemical method, you need to protect your hands with construction gloves, your respiratory tract with a gauze bandage, or even better, a respirator.
The surface of the radiator, cleared of paint, is treated with sandpaper. They work especially carefully in places where there is corrosion. It needs to be completely removed. Only a pure metallic sheen should remain.
For degreasing, use white spirit or any other alkaline solution.
The radiator is primed with a solution that meets the following requirements:
- is a product of the same manufacturer that produced the paint. In this case, the primer and paint work best together;
- contains substances that can resist corrosion.
Features of paint application
Before painting, the heating radiator must be cooled. This is because most paints are designed to be applied to a cold surface. If they are applied to hot metal, they will dry quickly. And this will not allow you to apply an even layer and correct smudges, stains and stains in a timely manner. In any case, when working on hot batteries, there is very little time for applying paint. In this case, the mistake made may remain uncorrected. This is often noted in various videos.
True, there are some exceptions. So, people who ask the question whether it is possible to paint hot batteries should pay attention to paints specially designed for this purpose. They are able to dry on heated metal very slowly. However, such paints are quite expensive, and the final result of the calculation small repairs will represent a considerable amount. Therefore, before painting the heating radiator in winter, it is better to turn it off and wait for it to cool. It is best to change the color of the heating device in the summer season. Then it is convenient to ventilate the room and the radiators are cold.
If you have to paint a cast iron heater during the heating season ordinary paints, then you need to apply a very thin layer of paint. Apply two such layers.
The application of a color mixture of a certain color occurs in the following sequence:
- Place oilcloth or old pieces of newspaper under the radiator.
- Applying paint to the top of the product. Then they gradually go down. Thanks to this, the problem of smudges is eliminated. First, the color mixture is applied to the internal parts of the device, and then to the external parts. The entire surface needs to be painted.
- Drying of the first layer of paint.
- Apply the second layer in the same way as the first.
The battery is coated with paint using various tools, namely:
- Brush.
- Spray gun.
- Spray can.
If you plan to use a brush, then you should take several options. The first should have soft, straight bristles. The other has curved stubble. Thanks to the second, you can work with your own hands in those places to which access is limited.
If painting with a spray gun, it is better to remove the battery. This way, excess paint will not get on the walls. In addition, there is a great opportunity to paint the most inaccessible places. Spray painting is very quick. In this case, you need to perform zigzag movements. They move from top to bottom. The distance from the surface to be treated to the can should be 30 cm.
How to paint a heating radiator: recommendations and photos It’s worth clarifying right away that painting heating radiators is not possible in all cases. First of all, it is advisable to perform this operation for cast iron radiators, a thick and uneven layer of paint on which not only spoils the exterior of the battery, but also greatly impairs the quality of heat transfer. The second type of batteries that can and should be painted are convectors, made in the form of a bent riser pipe with fins pressed onto it.
Painting cast iron radiators If you are the owner modern models radiators with aluminum sections, then it is better to abandon the idea of painting. Of course, you can paint it, but you will have to apply many layers of paint, and you are unlikely to achieve the expected effect. The fact is that the battery is painted with a brush, and this method is by definition worse than the factory one, so it is better to leave new battery models alone and, if necessary, cover it with a decorative screen.
How to paint a heating radiator: choosing paint and tools
Brushes for painting radiators Before you begin the main stage of work, you need to prepare. First, let's prepare soft brushes that should be small size and two types - straight and curved. The straight brush is intended for painting external, easily accessible areas, and the curved brush is for painting the rear and internal surfaces of the radiator.
Anza flat brush for painting heating radiators Which paint to choose
The main role in this work is played by paint for radiators, which can be following types:
- water-dispersed;
- alkyd;
- acrylic;
- oil
Any paint for heating radiators must be resistant to abrasion, withstand high temperatures (up to 100 degrees) and not release toxic compounds when heated. According to these parameters, the above options differ significantly from each other. For example, water-dispersion paints do not have an unpleasant odor and dry quickly, but this type of coating is less resistant to abrasion than others, meaning it will have to be renewed more often.
Special alkyd enamel VD-AK-1179 for radiators Acrylic paint contains a chemical solvent, so when used, an unpleasant odor is released, which for a long time ventilate from the room. The advantages of this coating are high abrasion resistance and an attractive glossy appearance.
Alkyd paint for radiators also has an unpleasant odor, but is in high consumer demand due to high stability to abrasion and a huge range of shades. In addition, the smell from modern building materials is not so strong.
As for oil paint, it is being used less and less as a coating for radiators and pipes. The reason for this is the unpleasant odor, long drying time and difficulty in applying an even layer.
How to paint radiators is up to you, but it is best to use alkyd paints from well-known manufacturers. All you have to do is choose suitable color coverings.

How to paint radiators: preparatory stage
So, the materials have been selected. Now you can move on to preparatory stage. Old cast iron radiators may have chipped paint and many layers on top of them, so you need to completely clean the radiator from the old paint to the metal. This operation can be performed using a hair dryer, which melts the old paint with a stream of hot air, after which it can be removed using a spatula.
Cleaning pipes and batteries with a grinder with a special nozzle
If you don’t have a hair dryer at hand, you can use alternative option– washing solution. This solution is applied to the entire surface of the radiator, after which the heating device is covered with a film. After the washing solution has been in action for an hour, the paint can be removed using a spatula.
The main layer of paint has been removed, now we clean the battery from its remnants using fine sandpaper or a special wire attachment for a screwdriver. Then degrease the surface of the radiator using a rag soaked in a special solution, such as white spirit. The final stage is to coat the radiator with an anti-corrosion primer; it will protect the radiator from corrosion, but will also improve the adhesion of the paint to the surface.

Painting a radiator: basic rules
It’s worth clarifying right away that painting the batteries should be done with the heating turned off. This limitation is due to the fact that paint dries very quickly on a hot surface, which can lead to an uneven coating layer and the formation of smudges.
How to paint a radiator after stripping Before painting the heating radiator, place an oilcloth or rag under it, which will protect the floors from paint getting on the floor. Start painting the radiator from hard-to-reach parts with a curved brush, and cover the front side with paint at the last moment. This approach will allow you not to smear the newly applied layer of paint, and your hands will remain clean.
Painting aluminum radiators with a spray can In order for the radiator paint to lay flat, it must be applied in two thin layers. To apply the second layer, you need to wait until the first one has completely dried.

Possible problems when painting
When implementing each stage of work, unexpected difficulties may arise - the paint does not apply evenly or the old coating is not removed. In order not to spoil the materials, you can pause work, wait for complete drying and start again by cleaning and degreasing the surface.
You can find out what paint to paint heating radiators from consultants in a specialized store; they will help you decide on a specific brand that is most popular among customers.
To avoid additional difficulties, pay attention to the video instructions, where experts will help you study the painting algorithm in detail and follow the detailed steps.
Bottom line
Painting radiators plays an important role, since this heating element attracts attention and is a subject of interior design and design. Using the above tips, you can ensure that the old cast iron battery after treatment it will look no worse than new, and the coating will last for many years.

Choosing odorless paint for radiators
The choice of paint and varnish coating for a heating system is a fairly pressing and undoubtedly important issue. The paint must meet the objectives: withstand high temperatures, maintain gloss for a long time and not peel off. But this is its functional and aesthetic load. But the question of which odorless paint for radiators and how to paint them sometimes remains open. An educational excursion into the world of paints and varnishes will help you figure it out.
Which one is better to choose?
The choice of paint for the heating system of an apartment or house is closely related to the material from which the batteries are made. Each type has certain properties that are friendly to the paintwork or conflict with it. The main types of materials used for the production of radiators:
- cast iron;
- bimetal;
- steel;
- aluminum.
For painting heating radiators, the manufacturer market offers a wide range of types and a rich palette of coatings:
| № | Types of paints and varnishes | Kinds paintable radiators | Advantages | Flaws | Firm- manufacturer |
| 1 | Oil paint | Cast iron | Wide color palette | It takes a long time to dry, has a persistent odor, quickly fades, cracks, and loses its shine. | "Tikkurila" etc. |
| 2 | Serebryanka | Cast iron | Excellent high temperature resistance | Persistent odor | “Lakra”, “Gloss”, etc. |
| 3 | Silicate paint | Cast iron | Designed for high temperatures | Long lasting odor | “Nevbytkhim”, “Ceresit”, etc. |
| 4 | Powder paint | Any kind | Durability, resistance to damage and high temperatures | Coloring in professional cameras | "Triton", "Ral", etc. |
| 5 | Alkyd enamel based on organic solvents | Cast iron, steel, bimetal | Wide range of applications | Characteristic odor, color varies by pigment | “Olecolor”, “Enamel”, “Tex”, etc. |
| 6 | Water-based alkyd enamel | Any kind | Barely noticeable odor, no loss of color | Titanium white is added to the high-temperature paints of this series, which are not cheap | “Tex”, “Lakra”, “Enamel”, etc. |
| 7 | Alkyd hammer enamel | Cast iron, steel, bimetal | Hides imperfections of the painted coating | There is a slight odor that disappears after drying | “Olecolor”, “Tex”, “Enamel”, etc. |
| 8 | Acrylic enamel | Cast iron, steel, bimetal | Almost no smell, dries quickly, wide range of colors, durability | It is necessary to carefully prepare the surface to be painted: sand, prime | “Lakra”, “Rainbow”, “Tex”, etc. |
| 9 | Spray paint | Any kind | Wide range of colors, ease of dyeing process | Strong smell | "Kudo", "Decorix", "Newton", etc. |
Is it possible to paint hot?
Experts have different opinions on the issue of painting radiators: some argue that they need to be painted to protect them from corrosion. Others retort that applying one or another type of enamel to heating radiators is of no use protective function does not fulfill and is purely aesthetic in nature. Another thing is painting pipes in winter, when the radiators are hot.
Paints and varnishes suitable for heating systems and withstanding high temperatures require painting over cold radiators. If radiators are coated with enamel on a hot surface, the paint will dry out “on the fly” and the quality of painting will get out of control: sagging and unsightly spots will appear.
It would be useful to remind you that when coating a hot radiator, the smell of paint will intensify, and opening windows winter period Ventilation is problematic due to the cold.
Important! Consumers most often choose white battery color, but experts say that dark tone Painting radiators promotes better heat transfer.
Painting process
Before you begin the paint application stage, you need to stock up on the necessary equipment:
- radiator brush (curved, with a long handle);
- regular brush (100 mm wide);
- rubber or silicone gloves;
- respirator (if the paintwork is odorous);
- newspaper (to protect the floor from paint stains);
- sanding sheet No. 2 (if necessary, cleaning batteries from uneven surfaces);
- rag;
- primer;
- dye;
- white spirit (for unexpected contact of paint with the skin).
Sometimes, preparatory work take longer than the dyeing process itself. This is not surprising, because the radiator has a lot of hard-to-reach parts that need to be washed, and in some places peel off the peeling paint and sand it.
Important! If you want to remove the old coating completely, you can use a special remover.
- Prime the prepared surface.
- In order to avoid drips, painting begins from the top of the heating system.
- The internal parts of the batteries are also covered first.
- Layers of paint are applied evenly in a thin layer.
- As the paint and varnish material dries, the radiators are repainted.
Radiator painting steps
Technology of painting over old paint
The condition of the paint on the heating system may vary:
- The coating, although old and faded, has a monolithic adhesion to the base. It is enough to just lightly sand the surface with sandpaper for reliable adhesion of the next layer of paint.
- The old coating has worn out in places, peeled off, and metal is visible in places. Here, more thorough grinding of the surface will be required so that chips and irregularities are not visible under the new layer.
- The paintwork is crusty, peeling off in large areas, and rust appears in places. Such paint must be mercilessly removed with a wire brush or special removers. The prepared surface is primed before applying the first layer of paintwork.
Important! You can simply renew the old paint: apply a fancy pattern to it, after sanding it for better adhesion.
In cans
For the convenience of consumers, paint and varnish manufacturers produce aerosol coatings for radiators. It has excellent properties:
- withstands high temperatures;
- easy and quick to apply;
- dries almost instantly;
- has a pronounced gloss;
- fits perfectly on any surface.
The only negative is the strong smell, but it will disappear in just an hour.
Balloon paint is sprayed onto the surface to be painted from a distance of 30 cm. Movements should be smooth, but fast, zigzag. Depending on the quality of the surface of the heating battery, painting in several layers may be required.
Important! When working with aerosol enamel, it is necessary to cover a large area around the radiator with newspapers, because The skill in painting with spray paint will not come right away.
Having the necessary information about heating radiator coatings, you can secure useful tips and learn the features of technologies for using paint and varnish products.
From time to time you need to bring the radiators to normal look. This is not only due to aesthetics, but also to extend the service life. There are many types of paints and varnishes on sale. But odorless paint for heating radiators is the most successful. It has a lot of advantages. It is available from different manufacturers.
When purchasing, you need to pay attention to the composition and it is better to choose well-known brands. The material from which the radiator is made is of great importance. It is necessary to take into account what material it was covered with before the repair. Some types of paints cannot be applied without first treating the surface.
Painted heating radiator in the interior of the room
Types of paints
Radiator paints are available in in different forms. They are designed for painting various metals. Some are suitable for external use, others only for internal use. Which means are better or worse, a beginner who has decided to make repairs with his own hands for the first time cannot immediately understand.
There is a basic classification of paints. Paint for heating radiators is:
- in the form of enamel;
- alkyd;
- acrylic;
- special.
Enamel
This type is used for painting pipes very rarely. The disadvantages are as follows:
- cannot be used at high temperatures;
- They smell unpleasant, and the smell is corrosive; you have to ventilate the room for several days.
There are a number of advantages:
- the assortment is rich;
- affordable price.
It is better not to use enamels for painting batteries. They are more often used for exterior work and painting walls.
Acrylic
This type of paint for radiators is widely used. Its peculiarity is that after drying the surface resembles plastic.
The main difference is that the material is odorless. Another advantage is that it dries very quickly. After 1.5-2 hours, the surface of the pipes will be dry. But such paint must be applied to a prepared surface. First, the radiator must be primed. The surface is painted in several layers.
The advantage is that when applied, the paint does not drag behind the brush. The consistency is similar to sour cream. It does not spread. The good thing about the material is that if a beginner decides to do the work with his own hands, it will not be difficult for him.
Just a note! Acrylic paint material has the advantage that it can even be applied to a hot pipe. It will not affect the quality of painting in any way. But you need to pay attention, the surface must be dry. Moisture ingress is unacceptable.
Like all materials, it has its drawbacks. This is low adhesion. After 2-3 years, the paint begins to crumble, but this material is better suited for radiators than enamel.
Alkyd
This type is acceptable for radiators. The paint is heat-resistant. After drying, an even, pleasant gloss is formed. It contains white alcohol, so it smells unpleasant. The smell is persistent and will last for several days.
It is of high quality. Long service life. Tolerates both high and low temperatures perfectly.
- takes too long to dry;
- unpleasant smell.
We must remember! If it overheats, even if the paint material is completely dry, the smell may reappear.
Special
Special
Intended for certain type surfaces. Each type has specific characteristics. Made for radiators, does not smell and dries quickly. The applied layer instantly adheres to the surface of the pipes. Minus in high cost. But all the advantages of paint will cover this disadvantage.
Paint selection
Colorful materials are selected depending on what the radiators are made of. Various metals and alloys are used for their manufacture. Therefore, you need to pay attention to the following:
- For cast iron pipes good enamels. Before you start painting, be sure to turn off the heating. This is done because, at high temperatures, the paint material will dry quickly, but will immediately begin to wrinkle. In addition, stains form on the surface of the pipes. If for some reason it is not possible to turn off the heating, then apply the paint in a very thin layer. It is better to use thinner.
- Aluminum, steel, bimetallic radiators are produced with a treated surface. It is coated with a protective powder. This makes it very difficult to paint again. Before applying paint, you will need to clean the surface with a sander. You should choose alkyd enamel or acrylic.
Radiator painting
Even if the paint for radiators is chosen correctly, the material is of high quality, but if painting is done without observing the basic technological requirements, the radiator will not look at a high level. It is especially important to study technological rules for those who are planning to do their own painting for the first time.
First you need to prepare the radiator for painting. To do this, do the following:
- Prepare the radiator for painting. Wash well with a soft cloth, a brush and always with detergent.
- Carry out degreasing. Using sandpaper, remove all roughness from the surface.
- Remove the old coating and treat areas exposed to corrosion with a special compound.
When the radiator is prepared, you can start painting. How to paint a radiator is described below. It is done as follows:
- turn off the heating, if this does not work, dilute the paint so that it can be applied in a thin layer;
- apply paint from top to bottom to avoid unwanted smudges;
- Be sure to paint all labor-intensive places, where you can’t get a regular brush, you need to use a special one for pipes. It has a curved shape;
- It is better to apply two or three thin layers, but before applying the next layer, you need to wait for the first one to dry well.
Sometimes spray cans and rollers are used to paint pipes. They can be used when hard-to-reach places have already been painted. For convenience, you can remove the radiator from its hinges and paint it. If possible.
Important! Even if odorless paint is used for the coating, the windows still need to be opened. All work must be done with gloves.
When choosing paint, you need to take into account the type of room. If the place is public, an office, then you can use cheap materials. When renovations are carried out in a city apartment, odorless paint is required, and this is especially important if renovation work planned in the children's room.
Many people use conventional paint materials for painting pipes, which are designed for working with floors, walls, and ceilings. This is not the best option. They are not suitable for use at high temperatures, so they spread quickly and acquire a yellowish tint on the surface.
If you have to choose between glossy and matte paint materials, then you need to take into account the fact that a shiny coating always attracts attention and all the flaws, irregularities and other shortcomings of the radiator will be visible. The matte light coating will quickly turn gray because dirt accumulates in the porous structures.
When renovating both residential and industrial premises, the choice of paint for radiators is especially important. It should be said that painting heating radiators not only performs an aesthetic function, giving them a presentable appearance, but also reduces the harmful effects of corrosion. In addition, the existing variety of colors and shades will allow you to paint the radiator so that it blends harmoniously with the intended interior.
The wrong choice of paint and varnish material can lead to the fact that when the radiators are heated, the room will constantly be filled with a pungent and unpleasant odor. To prevent this from happening, you should choose heat-resistant compounds that do not emit unpleasant odors and do not turn yellow when heated frequently. It is better to buy paint from well-tested brands, a little more expensive, but also of higher quality. This will significantly extend the life of the radiator.
In order not to make a mistake in your choice, before starting work you should study the basic properties and types of paints and enamels for radiators. According to existing standards for residential premises, paint for radiators must be odorless, non-toxic, resist temperature changes and withstand light mechanical damage. Heat-resistant enamels are made from a varnish solution, colored pigments, with the addition of various fillers, depending on the required properties. The latter components, in turn, affect the purpose of the paint. For example, adding organic resin to fire-resistant enamel helps to increase the complete drying time, but makes it more elastic and has a positive effect on the quality of protection.
Such enamels are used for painting concrete stoves and metal pipes, oil refining and oil production equipment and much more. Heat-resistant enamels can be used both on concrete and building surfaces, and on metal, including wires and cables.
The most optimal options when choosing paint for radiators can be considered the most common types of heat-resistant paints and enamels on the market.
