Very often in construction and finishing, artistic works Acrylic based paints are used. Such coatings are especially popular. This is due to their unusual color brightness and durability. Many people wonder what can be painted. The technology and application of coloring acrylic are worth studying. Well, we invite you to get acquainted with how to properly paint walls, facades, wooden and hardware, fabrics and even nail plates.

What is acrylic paint?

Acrylic-based paints are a substance based on polyacrylic polymers: methyl, ethyl and butyl. Also, some polymers are used to turn them into foam. It is dispersed, diluted with water and formed using pigment pastes. Also, to break them down, a solvent consisting of chloroform, ethanol and ether is used. They give off a very pungent odor.

Acrylic itself is synthetic material with transparent texture. He has good mechanical characteristics and resistance to high temperatures. Acrylic substances are very light and durable, resistant to UV radiation. The paint contains acrylic itself, small dispersive particles of plastic that tend to dissolve in water. After the paint dries, a film is formed that protects the painted surface from external influences. Here is the composition of any acrylic coating:

  • binder;
  • toner;
  • filler;
  • solvent;
  • additional particles.

The first binder holds all the ingredients together. This allows the coating to combine well with different surfaces. So binder Acrylic resins are often used. They give the paint strength, durability, and abrasion resistance. The type of acrylic resin determines the quality of the paint.

Soluble powder is used as a pigment. It can be of the following types:

  • with organic origin;
  • of inorganic origin;
  • manufactured artificially;
  • from a natural source.

The process of making paints with an acrylic base is not that complicated. First, the acrylic composition and the coloring pigment are installed in the container, then all the components are mixed into a homogeneous mass and packaged in a separate container.

Advantages of acrylic paint

Acrylic paints have many advantages over other paints and varnishes. They are most suitable for finishing work. They are universal and suitable for any surface. Here are their other advantages:

  • Environmentally friendly. For their production, substances that are harmless to humans and do not affect health are used.
  • Comfortable and easy to use. They do not have a special smell, so they are easy to work with.
  • Fireproof. Do not ignite and do not contain flammable substances.
  • Availability of unlimited color palette. A huge number of shades allows you to use it not only in coloring various designs, but also used by artists to paint pictures.
  • Dries quickly. It dries within 1-3 hours after painting.
  • Elastic, durable, easy to care for, abrasion resistant.
  • They do not contribute to the accumulation of dirt, allow air to pass through, and are resistant to moisture.
  • They differ in their durability (they do not lose their attractiveness for 10 years).
  • They have a wide scope of application. They are used in rooms, as well as outdoors under open sun rays.
  • Versatile and multifaceted. Used in combination with others building materials. They can be applied to any surface, excluding some types of plastic.

What can be painted and how

So, this type paints are used in construction industry, and in painting. Sometimes they are used to apply designs to the surface of cars or to create nail designs. If you don’t yet know how to paint with acrylic paint, then use the following tips:

  • clean the surface from dust, dirt and greasy stains;
  • material with high moisture absorption must be treated with a primer;
  • if the composition is too thick, add water and solvent;
  • It is better to apply with a roller, brush or spray gun;
  • carry out work at a temperature not lower than +10 °C;
  • Clean brushes, paint container, paint container and other accessories with plain water.

If you have not completely used up all the paint, then close the jar tightly with a lid so that air does not get in, which can change its properties and make it unusable.

Types of acrylic coatings

Depending on where acrylic paint is used, it is divided into the following types:

  • external;
  • internal;
  • automobile;
  • used in painting.

The façade acrylic coating contains substances and additives that improve its resistance to sunlight, moisture and abrasion. This paint can be used to cover facades, fences, benches, gates and other external surfaces.

Interior paints have less resistance to external irritants, but they work well. Finishing interior paints Available separately for walls and ceilings. Universal compositions with acrylic have also been developed, suitable for both indoor and outdoor work.

Depending on the additional functions paints with acrylic are found:

  • lightfast;
  • moisture resistant;
  • well-tolerant of mechanical stress;
  • washable.

Such acrylic coatings can still have a beautiful shine. In this regard, the following paints are distinguished:

  • glossy;
  • matte;
  • silky matte;
  • semi-gloss.

A little about thinners

It is best to dilute acrylic paint with water, because it is created on water based. But when the coating dries, a film forms on its surface that no longer allows water to pass through. Therefore, after painting, all working tools should be washed immediately before they dry.

How much water is needed for dilution? The ideal mass would be a 1:1 ratio. If you dilute 1:2, you get a thin layer that saturates the surface. The thinner the paint layer is needed, the more water added to the composition.

Some manufacturers offer their thinners directly. With them, the paint can already take on a glossy or matte appearance.

To dilute it, first grind it to a powder state. Next, this powdery mass is poured with hot boiling water twice, wait until it cools down and the water is drained, and the paint is mixed. Such processed mass is suitable for second-rate work, because it loses some of its properties.

Acrylic paints in painting

All artists know one feature of acrylic paints - after drying they darken. They are used as an alternative to oil tubes and use the same techniques for applying to canvas. Unlike oil, acrylic dries much faster.

For background images, artists use a liquid consistency diluted with water, and for expressiveness they use a paste-like mass. To do this, they often use special thickeners. Acrylic is good because it does not crack, unlike oil. It goes on very smoothly, has a shine and does not require fixatives or varnishing.

Artists paint with acrylic paints on wood, glass, metal, linen, and canvas. Fresh smears can be easily removed with water, while dried smears can only be removed with special solvents. To create acrylic paintings, gels, pastes, putties, and glue are used. Such masterpieces are distinguished by their special color rendition.

How to paint with acrylic paint correctly?

Water-based coatings are very easy to apply. To know how to paint with acrylic paint, you need to get acquainted with some technological aspects and subtleties. We invite you to get to know them:

  • First, prepare the surface for painting. Check the ceiling for dirty, greasy and dusty residues. Then level the base perfectly. Treat the ceiling with a primer that protects against mold and mildew and saves on paint costs.
  • If there is old paint left on the surface, carefully remove it with a spatula.
  • Be sure to repair cracks and chips with putty and wait until dry.
  • Grout and apply primer.
  • After this you can start painting.
  • Take care of the tools first. Which roller to paint with acrylic paint interests many readers. In addition to this device, you will need brushes, a paint reservoir, a ladder or a table.
  • The work should start from the corners, painting them with a brush. When you have painted all the edges around the perimeter, take a roller and boldly, stroke by stroke, paint the entire surface.

Methods of applying coloring mass to a surface

Acrylic paints can be applied to the surface in two ways. The first is to dilute the coatings with water or special mixtures. This composition can be applied in several layers. In the second case, a paste-like form of paint is used, which is achieved with a special thickener. Never dilute the paint in the container you bought it in; take a separate container, otherwise the moisture will evaporate and the residue will become unusable over time.

Painting wood with acrylic

Quite often people ask the question: “Can I paint wood with acrylic paint?” Yes, it really exists special type acrylic coatings for wooden surfaces. the latter require preliminary priming. For external works A water-based primer is suitable, and an oil-based one for interiors. A high-quality primer is good antiseptic. The answer to the above question is clear: “You can paint wood with acrylic paint.” Many people use it to paint timber or plank facades.

Facade finishing

Painting the facade of a house with acrylic paint is not that difficult. All you have to do is follow these steps:

  • Make sure there is no dirt or loose plaster on the walls. Check the façade surface for strength. Look to see if there is fungus anywhere on the surface. Fill all cracks and defects.
  • Apply primer. This will improve the adhesion of the paint to the surface of the facade and save material.
  • Take a roller and start painting. You will also need a brush. In some cases, they use a spray gun.

It is important to note that painting the facade requires two layers. The second layer should be painted only after the first has dried. Acrylic paint dries quickly, so you need to quickly apply stroke after stroke, otherwise the boundaries of the new joints may be visible.

Combination of acrylic and oil texture

You need to apply the paint material after thinking through all the details. The coating must be reliable and long term have the original appearance. It is especially important to take into account what kind of painting the surface was previously exposed to. You already know what can be painted with acrylic paint. It fits perfectly on many surfaces. But what if the room was previously renovated by someone else? coloring material? For example, can you paint with acrylic paint over oil paint or not? After all, so often in the old “Khrushchev” buildings of the last century, kitchen and bathroom panels were painted with an oil coating.

So should you remove oil paint before applying acrylic paint or not? Experts answer that it is possible to combine these two paints, you just need to use a special one. acrylic coating"Master-121". It has excellent adhesion properties and is considered universal. It is important that there are no cracks or chips on the old coating. First, the oil coating is ground with fine sandpaper, wipe off dust, degrease, and only then begin painting work.

Hot batteries and acrylic coating

During renovations in apartments, many people wonder whether it is possible to paint batteries with acrylic paint or not? After all, such a coloring agent must withstand high temperatures up to 90-100 ° C. It should not only look aesthetically pleasing, but also protect the metal from corrosion.

We can say that universal acrylic paint is also suitable for painting batteries. It is important that the heating is turned off during painting work. You cannot paint over hot batteries to avoid uneven layers and loss of color.

Combination with enamel

In addition to oil and acrylic coatings, enamel compositions are also found. They are used to paint metal, wood and plastered surfaces. If drying oil is added to an oil product, varnish is added to an enamel product. With it, the coating becomes glossy and aesthetic. If we consider whether it is possible to paint over it, the answer is categorical: “No!” The acrylic coating will simply lift the enamel and curl it. All this is because these two means various thinners or solvents. If, nevertheless, such an action must be carried out, then first a layer of neutral composition must be applied to the enamel surface.

Acrylic paints were introduced to the market half a century ago. It’s safe to say that this is a real breakthrough in the construction and repair industry. Today, this type of coating is preferred by most consumers.

Compound of this material simple. Comprises three elements: resin (binder), water and coloring pigments. Those who are not yet familiar with this coating are wondering whether it is possible to paint wood with it? The answer is undoubtedly yes. Moreover, this option has many advantages over similar formulations. How to paint wood with acrylic paint and how to choose the right product?

Features of acrylic paints

It is ideal for painting wooden surfaces. Thanks to huge selection color palette, everyone will be able to realize their design ideas in life. The material is environmentally friendly, so it can be applied to furniture, doors and windows, even in children's rooms.

After application, the coating does not release toxic elements. In addition, the paint does not have a strong odor. Therefore, you can work with it in public places.

Another advantage of this material is quick drying (1-2 hours). This is an absolute plus for those who want to do work quickly and at the same time with high quality.

In addition, there is no need to clean the tools used in the painting process with solvents and other unpleasant-smelling compounds. It is enough to rinse them under running water.

One more important feature acrylic is its long service life, which varies between 10-12 years (depending on the manufacturer). The coating is quite stable, which makes it possible to use cleaning agents on the painted surface.

Acrylic paint protects a wooden product from ultraviolet rays (due to the resins contained in the composition), mechanical damage. It is water-repellent, breathable, and resistant to temperatures, high and low humidity.

Acrylic coatings resist the formation of cracks and bubbles on the surface and have a high degree of hiding power, which allows for a minimum of layers to be applied.

One more distinctive feature is the ability to remove paint before it sets on the wooden surface. After drying, a protective film is formed on the painted products, which can only be removed by using special solvents.

Important: After processing the product with acrylic paint, it literally breathes. At the same time, protection of wooden products from pests is ensured.

Are there any disadvantages?

Despite many advantages, acrylic also has disadvantages:

  1. The price for a quality product is very high.
  2. If you store paint for a long time, then it may delaminate.
  3. Acrylic paints that are too cheap can lose their color, especially under the influence of ultraviolet radiation.

As you can see, the number of disadvantages is very small and they mainly relate to product quality. However, the existing disadvantages should still be taken into account if you want to paint wood with acrylic paint.

Selection rules

The choice of quality composition depends on what product you plan to paint. If its location is indoors, then it is recommended to select a coating intended for interior works. Such compositions create a smooth coating on furniture, interior doors and other decorative elements.

They do not lose color over a long period of time and are considered absolutely harmless. In addition, acrylic coating for interior spaces dries quickly, is easy to apply, and has no pungent odor.

It’s another matter if you need to paint objects located on the street - external doors, windows, facades, etc. For this, it is recommended to select a special coating made for external work. Both options differ in composition. The latter includes special elements that resist atmospheric changes (consists of coloring pigments, fillers, fixatives).

This composition ensures the reliability and durability of the coating, elasticity, protection from moisture and sun, quick drying and a high degree of vapor permeability.

This composition can be applied both to a new product and to old structures made of wood (only before this the surface must be thoroughly sanded).

It is preferable to store acrylic paint at a temperature not lower than 0 ͦ and not higher than 30 ͦ C.

Important! It should be mixed and diluted before use.

How to apply acrylic to a wooden surface?

Before using this material wooden crafts should be prepared for the process. Especially when it comes to old surfaces. If the facade, window, door, furniture are new, then there is no need for pre-treatment. Acrylic can be applied immediately.

So, if there are cracks, depressions, or unevenness in the product, then they should be repaired using putty intended for wood. If you plan to use a light-colored coating, then it is preferable to select the appropriate shade of putty, otherwise you will have to apply several layers of paint to mask the contrast.

After it dries, you should thoroughly sand the surface using grinder or sandpaper. It is worth noting that in in this case Care should be taken not to disturb the position of the fibers. Therefore, it is recommended to grind along their direction.

Next, the product should be cleaned of dust. To do this, you can use a vacuum cleaner or a damp sponge. Then you need to apply primer. This will ensure low paint consumption and good adhesion of the surface and the base layer.

Important: Do not use water-based primer for products located outdoors. It is better to purchase oil-based material for these purposes.

After the primer has dried, apply decorative layer acrylic paint. If you plan to paint a door, furniture or window, it is better to use a natural-based brush. For large-scale work, it is recommended to purchase a roller.

It is important that structures located outdoors are painted quickly after applying the primer. This is due to the fact that some types of soil are not susceptible to ultraviolet radiation and high temperatures(you can read about this in the instructions for using the primer).

Painting wooden products with acrylic paint is the most the best option. Moreover, this applies not only to those located indoors, but also located outdoors. The main thing here is to choose appropriate and high-quality material.

Acrylic and oil paints are used for finishing surfaces from the outside, as well as inside. In some cases it is necessary to cover the surface that has been painted with acrylic oil paint. To find out whether one paint can be coated with another, you need to consider the properties of each material.

Oil paint

Some time ago, oil paints were actively used to decorate surfaces inside and outside. But they were replaced by a new, more universal material, acrylic paints.
The oil material is made from drying oil or a similar product, which is mixed with pigments mineral type. The paint is obtained by grinding all components to a homogeneous composition. IN modern renovation oil paint is used very rarely. But in some cases it is advisable to use it as a cost-saving option for coloring large premises, since its cost is lower than other materials. The main advantage of oil-based paints is their low cost. Such materials are resistant to moisture, oils have reliable protection wooden, and concrete materials. Oil-based paints also prevent rust on metal surfaces.
This material has its drawbacks, which makes working with paint not very convenient. There are not too many colors, almost a dozen, so it is difficult to create a specific design and give originality to the surface.
Also, the paint needs to be renewed annually, that is, it wears out quickly, which requires additional costs. If the surface is not renewed in a timely manner, the material may peel off in large pieces. Appears during application strong smell, so work is performed in a well-ventilated area. When dry, the surface releases toxic elements, so it is best not to spend time in a painted room. A negative quality is the long drying time of such material, almost two days.
You can apply acrylic paint to an oil surface; this will not be difficult.

Acrylic paints

Compared to oil compositions, acrylic paints have clear advantages. Acrylic compositions are environmentally friendly and do not emit toxic substances, since they do not contain organic solvents.
The basis of this material is water, due to this there is practically no odor during application. The material also has a large number of colors and shades, this allows you to make the surface original. Required color You can order it from a hardware store, and it will be made on site. The acrylic composition has high stability to humidity, ultraviolet rays, and temperature changes, and also has good vapor permeability. Thus, acrylic paint is used to decorate the room inside and outside. The painted surface dries quickly, in just a couple of hours. If we compare oil- and acrylic-based paints, the latter are considered more durable and wear-resistant. Such compositions are considered universal and are used to create a variety of interiors.

Can you paint with acrylic paint over oil paint?

Typically, experts do not recommend applying acrylic paint to an oil coating that is too old, since the materials do not adhere well to each other. But such work is allowed provided that the surface is thoroughly prepared. Surface preparation work begins with sanding the previous coating, using fine-grained sandpaper.
After grinding, the surface is thoroughly cleaned of dirt and dust that has formed as a result of work; a vacuum cleaner can be used for this. Then the surface is degreased and left to dry. The dry surface is covered with 2 layers of acrylic-based solution. But thorough preparatory work They don’t talk about high-quality application of acrylic paint on an oil surface. To get the result, you must use a thick acrylic composition; when diluted with water, the proportions should not exceed 1 to 1.
If a spray bottle is used as the application tool, a suitable thinner must be added. The gloss or dullness of the surface depends on the type of this substance. Sometimes oil paint eats into the surface, especially if it is used too much. long time, then it is impossible to remove it. In this case, special paints are used that are characterized by high adhesion; they are able to efficiently paint even a very greasy surface.

Technology of applying acrylic paint based on oil composition

  1. First, the surface is sanded, all dust is removed using a vacuum cleaner.
  2. Then they are treated with a primer. And leave until completely dry.
  3. The acrylic composition is applied with a brush or spray; in the latter case, special thinners are used.
  4. Start applying paint from the corners of the surface to the middle or from top to bottom. After full coverage walls or ceiling, leave time to dry, usually a couple of hours; there are paints that dry faster.

Basic rules when applying acrylic paint to an oil composition

  1. To ensure a high-quality painted surface, it must be well prepared. The main oil layer of paint is removed by sanding, and then the dust is removed.
  2. All dirt must be cleaned off so that the acrylic composition lays down in an even layer.
  3. In too advanced cases. If oil has become embedded in a wooden or other surface, use special paints with a high adhesion rate.
  4. Surface sanding can be done with fine-grit sandpaper or special grinder. In some cases, a drill and a special attachment are used; you must act carefully so as not to damage the surface.
  5. Degreasing is a mandatory step, otherwise the new composition will not adhere well to the old surface.
  6. To ensure high-quality adhesion of the paint to the previous surface, the acrylic composition must have a thick consistency.

When choosing a paint composition, it is necessary to study its properties, all positive and negative qualities, since the service life of the coating and its reliability depend on this. Before purchasing material, you need to consider what kind of coloring will be done, primary or secondary. In the second option, a surface that has already been previously treated with other compounds is coated.

It is especially taken into account when the walls are painted with oil paint, these are the consequences of old repairs. Typically, oil paint was used for kitchens or bathrooms. When choosing modern acrylic-based paint, you need to figure out what to do with the old finish, namely oil composition. This article describes all the advantages and disadvantages of oil and acrylic paints.

Usually coated with oil paint acrylic composition not recommended, but it is possible if you resort to careful surface preparation. The old material is partially cleaned off by sanding with sandpaper, primed, and covered with acrylic paint.

Have you decided to start a renovation, but don’t know how to paint with acrylic paint correctly? It doesn’t matter, this article will tell you everything about preparation, painting and various important nuances, which will be useful when painting walls. But first you need to get to know acrylic paint better to see all the advantages of this material.

What is acrylic paint

Acrylic paints are paint material, made on the basis acrylic resins. This paint is odorless and can be safely used in children's rooms. It belongs to the water-based group, so you can wash your brushes and dilute it with plain water. During the drying process, evaporators erode from the substance, and the mastic creates a reliable and durable film. Acrylic paint can cover any surface, and complete drying time can range from 5 to 30 hours, depending on the temperature and time of year. Let's take a closer look at all the benefits:

  1. Has no smell.
  2. Diluted with water.
  3. Fireproof.
  4. Eco-friendly.
  5. Dries quickly.
  6. Easy to use - all you need to clean the surface is a cloth and water.
  7. Rich color spectrum.
  8. High adhesive qualities.
  9. It has pores, which allows the building to breathe.
  10. Resistance to chemical and atmospheric environments.
  11. Service life is about 20 years.

In the case of acrylic exterior paint, the service life is 10 years.

Painting with acrylic paint can be done at temperatures down to -30°.

Acrylic paint can have a different range of coverage, gloss, matte or pearlescent with different textures.

Where is acrylic used?

Today, acrylic paint is used in various fields:

  1. In construction – painting walls and facades of various buildings.
  2. For painting cars - acrylic car enamel is considered economical option, coloring metal constructions car, paint consumption is 3.5 times less than nitro enamel.
  3. In cosmetology - to create water-based varnish in order to eliminate acetone, which is harmful to health, from everyday use.

Due to its environmental friendliness, acrylic paint is used in hospitals, schools, kindergartens and other institutions. To ionize the air, silver particles are added to the paintwork material, so you can safely paint a child’s room or your bedroom.

Let's move on to painting work

As with any work, you can’t do without preparation; the better it is done, the easier it will be to paint. The first step is to remove all the furniture from the room. If this is not possible, then you need to place it in the center of the room and cover it. Remove all the facades of switches and sockets, if you plan to paint the ceiling, then the chandelier is also superfluous.

Old wallpaper needs to be stripped down to bare concrete or plaster, depending on what your house is built from. If, of course, you have special wallpaper pasted for painting, and you plan to paint over the old color, then in this case there is no need to peel off the wallpaper, provided that the quality of the coating is in excellent condition.

Inspection of wall quality

The walls must be perfect before painting, otherwise all the errors after painting will be obvious. Therefore, if the surface has chips, cracks and shallow dimples, then you need to putty them. But before this process, the wall surfaces need to be rolled with a roller with a primer solution. Traces of mold or mildew were found on the walls - this should be removed or treated with an antiseptic compound. Only after this, depending on the surface defects, can the walls be plastered or puttied.

Painting can be done on a puttied or pasted surface. special wallpaper. It all depends on finances and circumstances. What I mean by this is that painting a puttied surface is much cheaper than painting one covered with wallpaper. And in some cases it is necessary to putty and paste over at the same time, this is due to walls that have small cracks. For these purposes, non-woven or fiberglass wallpaper is used, as they have a large margin of safety.

Priming walls with prime

To increase the adhesion of paint to the wall, it is necessary to generously prime all working surfaces and wait until completely dry. Large areas you can roll it out with a roller, and those that are inaccessible can be passed with a brush, as a rule, these are all the corners.

What tools will you need for painting?

So that you can work calmly without distractions, it is recommended to prepare all the tools in advance:

  • brush – if you plan to make original drawings or paintings, you will need several brushes of different sizes;
  • roller with medium length pile;
  • telescopic (extendable stick) for painting high areas, including the ceiling;
  • paint tray with rolling board;
  • several spatulas of different sizes;
  • covering oilcloth for floors and furniture;
  • drill and paint stirrer.

Personal protective equipment:

  • workwear with long sleeves;
  • respirator bandage;
  • protective glasses;
  • gloves.

The paint itself is not dangerous, but it will be extremely unpleasant, especially when painting the ceiling, if liquid gets into your eyes or mouth. Here we come to main topic- how to paint a ceiling with acrylic paint.

Painting the surface with acrylic paint

In order not to stain the floor, it is recommended to lay down an oilcloth, otherwise you will have to clean the floor later; this is not difficult, but still extra work. You have planned to paint the ceiling and walls, then we start from the ceiling so as not to flood the painted walls later. But before you start painting, you need to mix the paint with a mixer, since the thick substance settles at the bottom. The thick mass can be diluted with water and mixed again. Ready composition it is necessary to pour it into a special bath or, as some also call it, a cuvette for squeezing the roller. It has a container for paint and an inclined squeezing board on which excess paint remains. Thanks to this device, the roller will be evenly saturated with paint, so it’s better than dipping it into a bucket and rolling the paint on the wall. In the latter case, the paint will apply unevenly. Of course, you can use a clean sheet of plywood and roll out the roller on it first, and then apply paint to the wall.

In hot summer weather, acrylic paint dries quickly, so you need to paint the wall from corner to corner. If you hesitate and combine the dried layer with fresh paint, a stripe will appear that will be difficult to paint over. Therefore, it is necessary to have time to paint the first layer before it begins to dry. You need to start by painting the corners with a brush, after which you roll from the corner with a roller. Do not wet the roller too much, otherwise it will drip. You need to roll the paint from the middle up and down, so the paint will be distributed evenly than if you start from the bottom up. We covered one wall with the first layer, move on to the other and so on in a circle.

Having rolled the first layer around the entire perimeter, you need to wait time; in hot weather this is approximately 20 minutes to 1 hour. After this, you can apply a second layer, but in the diagonal or longitudinal direction of the roller, so the surface will be better painted. You can finish here, but if after the second time there are still unpainted spots, then you should repeat the surface painting process a third time. I would like to remind you that the walls are painted only after the ceiling is painted. We will learn below how to paint the ceiling with acrylic paint.

Painting the ceiling

Painting the ceiling is a little more difficult, the fact is that your hands are suspended all the time, which is why you get tired quickly. Makes it a little easier this work telescopic stick that fits onto the roller. The principle of painting is the same as in the case of walls, the first layer is rolled out lengthwise with a roller, the second across, the third diagonally. If there is whitewash on the ceiling, you should tear it off; to do this, you need to wet the surface with warm water and remove the whitewash layer with a spatula. After which the surface is washed with a sponge and water to remove the remaining chalky mass. Next, the ceiling is primed, puttied, and painted. Paint for whitewashed ceilings should be liquid; thick paint can create heaviness, and the chalky mass can fly off.

Many people are interested in whether it is possible to paint with acrylic paint directly over the whitewash. Of course, it is not advisable to do this, but it is possible if you are too lazy to wash off the whole thing. To do this you need to buy a primer deep penetration and saturate the whitewash layer so that it adheres well to the floor slab. Give it time to dry well and you can paint. But there is one caveat - if you run a roller over the whitewash for a long time, it may get wet and swell. That is why you need to do everything quickly, and after the first layer, let it dry thoroughly.

For ceiling surfaces, special acrylic ceiling paint is sold, which comes in white, super white and milky white. To create a special tone, you can use color paste.

Artistic painting

You've decided to paint a wall with an unusual design, but you have no idea where to start. As in those cases, the surface must be made perfectly flat finishing putty, prime with primer and let it dry. After this, you can paint the walls with acrylic paints. The finished drawing should be varnished, so it will look aesthetically pleasing and will remain in its original form.

Painting a wooden surface

Using acrylic on wood is not much different from using it on concrete or plaster surfaces, with the exception of metal and plastic.

Acrylic paints are popular among artists and are widely used for painting on wood. Such popularity arose due to the ability of paint to create protective film enveloping a painted object. This coating does not fade or crack, and is resistant to aggressive influences and sudden temperature changes. Professional artists use paint in tubes for painting, which allows you to achieve a watercolor effect thanks to special solvents and plain water.

Technique for using acrylic on wood

How to paint with acrylic paint correctly - before painting, the wood is sanded with fine sandpaper, after which primer is applied. Then the grinding process continues. This technique allows you to paint a wooden object better.

The widespread use of acrylic paint is in demand due to the versatility and uniqueness of paintwork materials. And the ease of applying paint to any surface allows you to paint it yourself.

Every second family in our country is constantly renovating their home. The renovation goes from the bathroom to the kitchen, from the kitchen to the balcony, then through all the rooms and again in a circle. The renovation is being delayed due to a lack of funds for materials for the entire apartment/house at once and for hiring a professional repair team. That's why Finishing work are often done with your own hands, and the question is whether it is possible to paint water-based paint according to oil, is asked by almost every family leading a “repair” lifestyle.

For specialists this is not a question. A professional finisher will clearly answer that all the old oil coating needs to be completely removed, will do this, re-prepare the surface for painting and ideally apply a new one paint and varnish composition. But... he will ask for a tidy sum for the work. Homeowners in search of more economically accessible and less labor-intensive options are perplexing themselves and perplexing manufacturers of paint and varnish products.

So is it possible to apply a water emulsion to oil paint, and which one is better? And yet, the answer is: you can use water-based emulsion, but certain conditions. First of all, it is worth considering the question of the intensity of use of the place that is to be painted with water-based oil paint, and then answer the question - can it be painted or not. If this is the ceiling or the top of the wall in the living room, then you can choose without hesitation desired color and after a little preliminary preparation, paint with enamel.

If you are planning to paint a cramped hallway with protruding corners with water-based paint over an oil-based coating, then this idea will seem promising at first, but after a couple of weeks of use it will become clear that this was a bad idea. Even with very high-quality preparation and compliance with all application rules, with frequent intense friction, water-based paint will quickly rub off from a smooth surface. oil coating.

Condition 1. Painting with water-based paint over previously applied oil paint is allowed if the area to be painted will not be subject to intensive use.

Is there an easier way?

Yes, this principle of homeopathy applies to the preparation of colored oil base. Its essence is to cover the old oil layer with a fresh layer of drying oil. For good adhesion of drying oil to paint, the old coating is thoroughly washed and degreased with any suitable composition, the easiest - warm water with soap. Drying oil is applied thin layer onto the old cleaned coating, forming a rough, slightly sticky surface that “accepts” any subsequent painting well. It doesn’t matter what kind of paint the surface will be painted with.

Treatment with drying oil is more economically expensive than simple priming, and is less comfortable due to the persistent strong odor and drying time, but in the end it gives a high-quality result.

To summarize, there are three ways to prepare a base painted with oil paint for subsequent coating with water-based paint:

  • priming (ordinary construction acrylic primer or special for old paint);
  • grinding/sanding followed by thorough cleaning of dust and priming;
  • applying a layer of drying oil to a previously cleaned surface.

Condition 2. Painting with water-based paint over oil-based paint is possible if the substrate is properly prepared.

Surface preparation

Carefully inspect the oil finish that is to be repainted. Typically the coloring is from the late 80's or much earlier. In the 90s it was already actively used everywhere water-based painting. Almost all surfaces were painted using water emulsion.

Oil-painted surfaces from those early years are distinguished by enviable durability; it is not so easy to “tear off” such a coating from a wall or other surface, unless together with plaster. Even “killer” chemical solvents are sometimes powerless in the fight. With water emulsion everything is much simpler. Here, primer manufacturers came to the rescue of home-grown finishers.

Coating oil paint with the simplest acrylic primer will create smooth surface slight roughness, allowing the water-soluble coloring composition to “catch” on a slippery surface.

Better surface preparation can be achieved by pre-grinding with fine emery cloth. For this “procedure” it is better to use a grinder with grinding disc or a drill with a special attachment.

It is unlikely that it will be possible to sand a large area by hand. The big advantage of this method is that unevenness, roughness and smudges of the old oil coating are simultaneously removed. The downside is that it's long and dusty. Sanding will not eliminate the need for additional work on thorough cleaning and priming, but will significantly improve the adhesion of primers and paints. water-based compositions to old oil paint.

How to paint correctly

Painting a well-prepared surface will not be difficult. It is carried out with brushes or a roller in two layers. It is important to observe the direction of movement of the brush relative to the incident light so as not to leave streaks of paint and the paint lays down evenly. The paint should be a little thicker, especially if no sanding was done, because the absorbency of the surface is still low. At liquid paint three layers are applied.

Also unavoidable three layers, if the surface was previously painted in dark color, and it needs to be made light. Better pick high-quality composition with good covering properties.

Condition 3. Using a good water-based paint with a slightly thicker consistency in several layers will help hide the old layer of oil paint.

To cover an old oil finish with acrylic paint or enamel, the same conditions will need to be met, but fewer final coats will be required. Is it even possible to paint with acrylic paint over oil paint and will it adhere to the previously painted composition? This should not be done, since good adhesion of the materials cannot be expected.

And, finally, a little secret: lightly sand the dried surface painted with water-based paint with fine sandpaper, you will get a perfectly smooth, flawless matte finish. And no one, not even the most “cunning” master builder and finisher, will guess that underneath there was a thick layer of shriveled gray-brown “Sovdepov” paint.
