What kind of renovation can there be without putting the ceiling in order! You can do this most different ways, one of the most commonly used paints not so long ago was whitewashing. This made it possible to make a beautiful, snow-white ceiling using the simplest and inexpensive materials, like lime, chalk, paste and others. Important here and proper preparation ceiling to whitewash, when carefully removed old layer whitewash, the base is leveled.
Almost anyone can prepare a mixture for whitewashing. This requires chalk, lime, special chalk paste, and blueing. All of the components listed can be purchased at any hardware store. Approximately 0.5 liters of chalk is required per square meter of surface liquid solution, but it is recommended to first try it on a small area to determine the correct layer thickness. In order for lime or chalk to be of high quality, it is not necessary to buy ready solution, you can do it yourself.
Before cooking, it is recommended to sift the chalk to remove all large particles and impurities. After this, 1.5 kg of chalk is poured into the container and 2.5 liters of water are poured. The solution should be homogeneous and free of lumps. We filter the resulting mixture through three layers of gauze, after which you can begin to work.
You can also use ready-made mixtures, which are simply filled with water, lime and blue. Over the years of its use, a lot of options for whitewashing have accumulated; each owner has his own recipe, but there is one “but”. In order to properly whiten the base of the ceiling, you need to take into account what mixture was used before. If chalk was used, then the chalk solution must be whitened this time too, otherwise ugly, dirty stains will appear on the surface, which will be very difficult to remove. It also takes time, and this work is dirty, leaving behind a lot of dust.
Applying whitewash to the ceiling
To renew the whitewash, you must first properly prepare the surface, that is, remove all traces of the old coating, putty and prime the base, after which you can begin applying the mixture to the ceiling. This is a traditional finishing method that has been proven over the years, so there are also rules for working here.
Before whitewashing the ceilings with chalk or lime begins, the surface should be thoroughly cleaned of traces of the old coating.
This work is very dusty, dirty, and takes certain time, but in order to properly and efficiently update the ceiling, you must first remove the old whitewash.
You will have to first do the following range of work:
- remove the furniture from the room and cover the remaining pieces with film covers;
- cover the floor with film, as cleaning it later will be problematic;
- prepare a table or a reliable stepladder for work;
- For protection, prepare goggles, rubber gloves and a respirator.
Can be done with your own hands various methods, among which:
- dry cleaning. That is, the ceiling is simply cleaned of old whitewash using a metal spatula. This method is the slowest, most labor-intensive and dirty. Dust will be everywhere, the process is long, for large premises not recommended, and it will be extremely difficult to work in small ones;
- The second cleaning method is to simply wash away the old whitewash using a hard rag or brush. This requires significant physical effort, and there will be a lot of dirt;
- can also be used washing vacuum cleaner, which will minimize time and physical effort, but the equipment may fail, so take risks household vacuum cleaner Not recommended;
- The next option on how to clean off old whitewash with your own hands is this: first wet it with a spray bottle small area, after soaking, the old whitewash is removed with a scraper. The remaining small mass is removed with a damp cloth. This method is suitable for small spaces;

To do this, we will need to dilute two tablespoons of laundry soap and five tablespoons of soda in warm water (10 l). Using an ordinary sponge and this solution, old whitewash will quickly be washed off the ceiling;
- You can remove a lot of whitewash with a paste solution, which is applied to the surface and, after drying, knocked off with a metal spatula (do not forget to place the container on the floor so that the broken pieces fall into it);
- the most quick option is the use grinding machine with a coarse abrasive wheel. But this method is very dusty, the room must be completely closed, and safety glasses and gloves must be used.

So, the first step is to prepare the ceiling for further work. When cleaning the previous layer of whitewash, be sure to wear a respirator so as not to harm your health. This whole process is quite dusty. The following recommendations will be useful to you:
- If possible, remove furniture from the room where work is being done;
- Cover the floor and remaining furniture with film;
- buy rubber gloves and glasses.
There are several ways to remove chalk from the ceiling:
- dry cleaning (old whitewash is scraped off with a spatula; sometimes a paste solution is first applied and left until completely dry);
- blurring the whitewash (it is gradually washed off with a brush or a hard rag dipped in water);
- mixed method (a small area of the surface is sprayed with a spray bottle, then a scraper or a wet rag is used to remove the whitewash);
- soap solution (2 tablespoons of laundry soap diluted in 10 liters warm water, add 5 tbsp. soda; the solution is applied with a sponge, the soaked layer of whitewash is carefully removed);
- using a grinder (involves a lot of dust).
Then the cleaned surface should be puttied and primed.
How to putty a ceiling
You can prepare the putty mixture yourself:
- Dilute wood glue (50 g of glue will require 1 liter of water).
- Combine glue, chalk and plaster (in a ratio of 2:2:1).
- Stir until smooth.
- Apply to the ceiling.
You can also use this recipe to prepare putty.
- Dilute slaked lime with water (2.5 kg per 5 liters of liquid).
- Enter table salt(4 tbsp is enough), add water so that the total volume is 10 liters.
- Separately, mix chalk (200 g) with glue (10%, 1.5 l).
- Knead each mixture and combine.
- Apply putty to the ceiling.
A small amount of the mixture should be scooped up with a spatula and distributed over the ceiling. The tool should be held at an angle so that the putty is applied evenly. After the first layer has dried, you can repeat the procedure. Try to immediately level the edges at the junction of the layers, otherwise it will be difficult to do this after drying.
How to prepare a primer
After puttying, the ceiling needs to be primed. For this you will need:
- 50 g drying oil;
- laundry soap;
- 3 kg slaked lime.
First, grate the soap on a coarse grater and dissolve it in hot water. Then add drying oil. Separately, dilute the lime with water, combine the soap solution with the lime solution. The total volume of the mixture must be brought to 10 liters using water. Knead the solution with your hands and apply it to the ceiling with a roller.
If you don't want to spend time preparing a primer, you can purchase ready mixture in a hardware store and simply dilute it with water, following the instructions on the package.
How to properly dilute chalk for whitewashing a ceiling
The whitewash solution can already be purchased at finished form, or you can cook it yourself. The average consumption of raw materials is 0.5 liters of solution per 1 sq.m. To make a solution for whitewashing, you may need: lime, chalk, blue, wood glue, chalk paste.
One of simple recipes the next one is considered. Sift the chalk, remove impurities and large particles. Pour 1.5 kg of chalk into a deep bowl, add 2.5 liters of water and 30 g of wood glue (it can be diluted with a small amount hot water).
Mix well so that there are no lumps left and the mixture is completely homogeneous. Then the solution must be filtered through gauze, folded into three layers. And you can start whitewashing!
Usually the solution is applied to the ceiling surface with a brush or roller, but if you have a sprayer you can make your task much easier.
The ideal concentration of whitewash is considered to be one at which an object immersed in the solution is painted evenly, while an even stream flows from it.

How to whitewash a ceiling with chalk
You need to start whitewashing from the window into the room. This will avoid unsightly surface shine. When the first layer dries, it is advisable to re-treat the surface to obtain a better result. In this case, the second layer must be applied perpendicular to the first (this will help reduce the number of streaks). If you work with a roller, it is advisable to brush the corners so that you get an even layer everywhere.
When all the work is completed, it is necessary to exclude drafts until the ceiling is completely dry, as this may impair the quality of the work. You should also protect whitewash from direct sun rays, otherwise it may crumble.
It is important to remember that when re-processing the ceiling, it is advisable to use the same materials (lime or chalk mortar) as the previous time to avoid streaks. How can you determine which solution is applied to the ceiling? It's very simple: lightly moisten the surface and watch the whitewash reaction. If fingers become stained, chalk was used. If the surface darkens, but the fingers remain clean, lime was used.

White color is universal: it goes with any style and any stop, visually increases the height of the room, creates Better conditions for lighting. Whitewashing with chalk is the most affordable way get the purest white color.
Chalk and its use
Chalk is a sedimentary rock consisting almost entirely of calcium carbonate. IN construction work material used for finishing works in order to obtain a white, smooth surface.
When working with chalk solutions, certain precautions should be taken.
- Glasses and a respirator, or a gauze bandage - despite the complete inertness of the material, the form in which it is used is a fine powder, causes irritation of the mucous membrane if accidentally inhaled or long work. For the same reason, animals and small children should be removed from the apartment during the work.
- Gloves - chalk solution, thanks small size particles, eats into the pores of the skin. To prevent this, it is recommended to wear gloves and wear long sleeves when working.
Preparation of the solution
Traditionally, two compositions are used: chalk mortar and lime mortar. Chalk is different in that it provides a pure white color. If the ceiling was previously whitewashed with lime mortar, then using chalk mortar is not recommended - there is a high probability of stains.
To make your own solution you will need the following ingredients:
- Chalk – at least 3 kg. You can buy powder or paste. The color of the powder is gray, the whiteness of the material appears only after whitewashing;
- Laundry soap – about 50 g;
- Wood glue – 100 g;
- Blue – at least 10 g. Blue provides stability white.
For 1 sq. m. surface requires about 0.5 liters of solution. Based on the ceiling area, ingredients are purchased in the required quantity.
- Place chalk powder in a container of the required volume and pour warm water– 3–3.5 l.
- Soap, glue and blue are gradually added to the solution with constant stirring. It is recommended to use a mixer because the two components are insoluble in water and it is not easy to get a homogeneous mixture by hand.
- Filter the solution through a layer of gauze to remove lumps. The composition is considered ready if it does not flow from the knife blade. Otherwise, it is recommended to add a portion of chalk.
Ceiling preparation
Before whitewashing ceiling covering needs to be brought into proper condition. Cleaning work is accompanied by a large amount of debris and dirt, so before starting repairs, you should remove as many pieces of furniture as possible from the room, and carefully cover the remaining ones with film.
- If there is old whitewash on the ceiling, it should be removed. To do this, the ceiling surface is moistened with warm water with the addition of vinegar. Wetting is recommended to be done in parts, as water dries quickly.
- As soon as the water has been absorbed, the old whitewash is removed with a spatula. If possible, it is recommended to install a tray under the area to be treated so that the scraped pieces do not scatter all over the floor.
- Residues are removed with a damp sponge.
- The ceiling should be treated with an antifungal primer. The chalk composition does not have antibactericidal properties.
Whitewashing with chalk
The ceiling can be whitened either manually - using a brush and roller, or with a sprayer. Both methods are easy to do with your own hands and do not require any special skills other than careful execution.
- The ceiling surface is mentally marked into several squares measuring about 1 * 1 m.
- The solution is thoroughly mixed before use, since chalk, being an insoluble component, settles quite quickly to the bottom of the container.
- The chalk solution is applied with a roller to the treated fragment twice. The second layer is applied after the first has completely dried.
- If a brush is used, then the first layer is applied with movements away from the window, and the second - perpendicularly. This technique allows you to hide traces of brush movement as much as possible.
The video covers the DIY whitewashing process in detail.
Whitewashing with a spray
This method saves time and allows you to achieve an even matte finish. A vacuum cleaner with a blowing function is used as a blower element.
- The solution is thoroughly mixed and placed in a half-liter glass jar. A sprayer is installed on the jar.
- The vacuum hose is connected at one end to the sprayer, and at the other end to the blower hole on the vacuum cleaner. Using the second hole on the sprayer lid, the supply of solution is regulated.
- Application of the composition is carried out with smooth circular movements. The distance between the spray nozzle and the ceiling surface is 70–100 cm.
Good luck with your whitewashing and renovation in general!
Of all existing options For finishing the ceiling surface, the most popular is whitewashing. This is explained by its widespread use due to the affordable cost of carrying out the work and obtaining a good result.
Typically, new whitewash for walls and ceilings is applied after the surface has been thoroughly cleaned of the previous lime and chalk. A new layer of paint can be placed directly on top of the old one. But you need to know how to do it correctly so that the end result is beautiful. It will not take much time to put the ceiling in order, and such work can be done with your own hands.
Materials for whitewashing the ceiling surface
First of all, you need to decide how to whitewash the ceiling in your apartment by choosing one of the options. Each of them has advantages and disadvantages.
It could be:
- lime;
- water-based paint.
As for such a material for whitewashing the ceiling as chalk, it will give the repaired surface a radiant whiteness. Despite the fact that the premises will have good view, additional dust will appear in it. This is explained by the fact that the chalk will gradually begin to crumble. Also this material It is not waterproof, so it is not suitable for repairing the ceiling in the bathroom.
Whitewashing using lime is an excellent way to combat fungus. In the rooms where it appeared, this should be used. In addition, lime on the ceiling is resistant to high humidity. It can be used to paint the ceiling surface in any room, including the bathroom. Lime whitewash successfully hides minor defects such as cracks and cracks.
Before whitening the ceiling with lime, you should take into account the fact that this material can cause an allergic reaction. Also, the surface is not perfectly snow-white, unlike a chalk-based composition.
The ceiling after applying water-based paint has an excellent appearance, it adheres well to the previous coating. The composition sticks to old whitewash and does not begin to peel off over time. This paint has the only drawback - when using it, repairs can be carried out at temperatures from +5°C. But when painting the ceiling is done indoors, this circumstance does not matter.
If you do not want to wash off the previous layer from the surface, then you should know that whitewashing the ceiling using old whitewash has a number of nuances. The fact is that chalk cannot be applied to lime, and vice versa, otherwise the new layer of finishing will not fit well, resulting in dirty stains appearing on the ceiling surface.
It is permissible to apply the same layer or water-based paint on top of the chalk solution. If the old whitewash on the ceiling was lime-based, it can only be covered with the same material or an emulsion coloring composition. In addition, you need to take into account that on old chalk or lime layer do not apply enamels or oil paints.
Tools for whitewashing
Before you whitewash the ceilings yourself, prepare necessary tools- such work is performed in one of three ways, for which they use:
- roller;
- sprayer, also known as a spray gun;
- brush.
If painting is done with a roller, then the coloring composition will lie in an even layer, without forming spots or streaks. To get a good result, whitewash is applied in two layers. You will need to have not only a roller, but also a container for the solution, a mixing tool, a paint tray and a small brush for applying paint where the ceiling meets the wall.
A brush for whitewashing can be purchased at any building materials store. affordable price. When using it, the composition splashes, so you should protect the furnishings in the room from it and use special eye glasses.
The use of a sprayer allows you to lay the whitewash in an even, neat layer. Using a spray gun to whitewash the ceiling, you will reduce the time it takes to complete the work. When using paint, make sure it is free of lumps. Its consistency should be more liquid compared to whitewash, which is applied with a roller or brush.
Choosing water-based paint
If, when deciding on the best option to whiten the ceiling, you decide to use this type of paint, then you need to take into account that there are many varieties of them, they differ in composition and properties:
- Polyvinyl acetate paints. They are the most affordable.
- Water-based emulsions with acrylic additives. They are the most popular. They are used for different surfaces, they are resistant to abrasion, but for ceilings this does not matter.
- Silicone paints. If the ceiling whitewash is being repaired, it can be done without using a primer. This painting composition is distinguished by a high degree of vapor permeability; it is suitable for painting ceiling surfaces in the kitchen or bathroom. This paint can reliably protect the ceiling from fungus.
- Water emulsions with latex. They have excellent water resistance, surfaces painted with them can be washed with detergents. Such compositions are the most expensive among similar products.
To decide which whitewash is best for the ceiling, before purchasing water-based paint, you need to carefully read the label, which indicates the purpose of the composition, consumption per “square” of area and other important information.
A correctly selected composition allows you to create a durable snow-white ceiling covering - it will not turn yellow over time and will be reliably protected from the appearance of fungus.
Whitewashing using water-based paint
Before whitewashing ceilings, applying water-based emulsion over lime, the previous layer should be pre-coated acrylic primer. Then it doesn’t hurt to make sure the surface is durable; to do this, you can try to scratch it.
Paint is applied only when the ceiling is not crumbling. When painting over chalk, there is no need to do any preparation. Water-based composition will stick to the ceiling without using a primer.
Before starting renovations, you should prepare the room. Objects in it are carefully covered with film or taken out of the room to protect them from paint.
More convenient and simple process painting is to use a roller, for which proceed as follows:
- Paint is poured into a paint tray.
- The roller is dipped into the container and rolled along the inclined side of the tray so that the paint is distributed evenly over the surface and its excess runs off.
- The first layer is laid perpendicular to the window openings.
- Wait until the paint has completely dried.
- After this, the next layer is applied, placing it parallel to the windows.
- Using a brush, finish painting the sections of the ceiling where the ceiling connects with the walls.
Spray paint is much easier to apply. It is necessary to apply three layers, and you do not need to follow the direction of painting. The main thing is not to miss a single centimeter of the ceiling surface.
Repair with chalk
Before you make a ceiling with whitewash, you should prepare a chalk solution, for which 10 liters will require 50 grams of wood glue and 5 kilograms of chalk. Its consistency should be such that the composition does not drain from the knife. If this is not the case, add chalk. You can add blue to the mixture to make the surface snow-white, without yellowness.
The technology for repairing a ceiling with chalk is no different from the process of applying water-based paint. First, choose a repair tool - a brush, roller or sprayer. The composition should lie in an even layer.
Quite popular today is adhesive whitewashing of the ceiling, which contains glue; it is much easier to apply and holds more firmly. If covered simple chalk If the surface touches it, it can get your hands dirty, but adhesive painting has no such disadvantages. In addition, this whitewash can be given any color shade.
Lime whitewash
For the preparation of lime mortar To paint the ceiling surface, take 2.5 kilograms of lime, add 100 grams of salt, pre-soaked in water, and also a little blue. All components are mixed, and water is poured in so that the resulting volume of the mixture is approximately 10 liters.
The rules for how to whitewash a ceiling with lime are similar to the recommendations for how to apply water-based paint and chalk mortar.
Important nuances
When repairing the ceiling surface, you should take into account the purpose of the room. For example, if it is a bathroom, application is required special staff resistant to high humidity and capable of protecting the ceiling from fungus. Otherwise, the paint will lose its attractive appearance within a short time and, most likely, will begin to crumble.
When performing painting work, it is necessary to remember safety, since the whitewash must not come into contact with the respiratory system, eyes or skin. To do this, use a respirator, rubber gloves and special glasses. The fact is that the coloring composition can cause serious allergic reactions, and sometimes chemical burns.
Removing old whitewash from the ceiling
Despite the fact that there is a technology for how to whiten a ceiling with your own hands without washing off the previous layer, to obtain a high-quality result you need to clean the surface and be sure to level it.
You should definitely wash off the previously applied whitewash that does not adhere well to the ceiling. If it is not removed, you cannot expect a decent result. When the chalk or lime layer is smooth, thin and firmly in place, painting can be done over it.
If you still need to prepare the ceiling for whitewashing, proceed as follows to remove the chalk:
- The foam sponge is moistened in water so that it becomes damp and drops do not drip from it.
- They pass it over the surface over and over again, thereby washing off layer by layer, wetting it as often as possible.
- Finally, wipe the ceiling with a wet cloth, frequently dipping it in water.
As for the lime layer, it is much more difficult to remove:
- First of all, moisten the entire ceiling surface, for which you can use a spray bottle.
- The soaked material is removed with a scraper or spatula.
- Then thoroughly wash the ceiling with a sponge or rag to remove any remaining dust and lime.
It is better to work in sections: while the soaked lime is removed from one of them, the surface of the other absorbs moisture. As a result, you can prepare the ceiling faster. Also, special means are used to wash off the previous whitewash.
Building materials stores sell a remover that is applied by spray. After it dries, a crust forms on the ceiling; it must be removed with a scraper. Finally, wash the surface with a rag.
There is another option for deleting the old layer. Vinegar is added to the water in the amount of one tablespoon per 5 liters and 50 milliliters of bath foam. The components are thoroughly mixed and applied to the ceiling. After 20 minutes, it is cleaned with a scraper and wiped with a wet cloth.
There is another way to clean old whitewash. You need to mix water and flour. The resulting paste is applied to the surface and allowed to dry, after which removing the old layer is not difficult.
Professional ceiling painting
If you do not have enough skills and knowledge on how to properly whitewash ceilings, you can use the services of professionals. This decision has many advantages. It allows you not only to save time, but also to get excellent result. A professional will spend a minimum of paint on whitewashing the ceiling, so the repair will not cost much more than painting by yourself. The main thing you should pay attention to is the skill of those who are to be hired.
It must be remembered that whitewashing old paint is inexpensive and in a simple way transform the interior of the room into better side. It should not always be used and only when the previous layer is even and holds up perfectly. In this case, water-based paint, lime, and chalk applied directly to the old base will adhere reliably.
Whitewashing is not difficult. You need to turn to experts for help and hire professionals in order to save time if the owner of the premises is a busy person and does not have the opportunity to carry out repairs.
The modern world of design dictates its own rules and laws. A special place here is occupied by ceilings, which Lately can be done different ways. Modern and multi-level ceilings with lighting they look incredibly beautiful and impressive, but for this elegance you need to pay a tidy sum of money, which, sometimes, is not left at all.
Which ceiling is better to make and at the same time spend the least amount of money? The answer lies in a long-tested method - whitewashing. This easy way has been known for many years and remains relevant to this day.
Having a lot of advantages over modern solutions, whitewashing the ceiling can be done in several ways. A person who has basic skills in working with simple tools and knowing the essence of the work, he will do it with ease.
The first thing you need to do before starting the actual whitewashing is prepare the surface. This stage includes the need to produce a current and level its surface. If you need to achieve a long-term and high-quality result, it is not recommended to neglect this stage.
The entire preparation process begins with cleaning the ceiling before whitewashing. The need for this is due to a number of factors: it will be easier to assess the condition of the ceiling, the old coating may peel off and fall off over time, or be visible through the new coating, and, finally, only on a well-prepared surface will the whitewash be of the highest quality and most durable.
To perform all repair and cleaning work, the following materials are required:
- Brush or roller;
- Putty knife;
- Ladder;
- Perforator or hammer;
- Water container or spray bottle.
If the ceiling was previously finished with paint, it can be removed with a special wash or mechanically. In the first case, the surface is treated with a chemical liquid, in the second - a hammer is used. You can choose any of the proposed methods, but using a hammer will require a lot of effort and time, and chemical treatment is harmful to health.
If the ceiling was covered with wallpaper, then the procedure for cleaning it is as follows: the surface is moistened with warm water, allowed to settle, and then the wallpaper, soaked in water, is removed. Several such procedures are required before complete cleaning.
Ceilings finished with water-based paint or whitewashed surfaces are cleaned with warm water, followed by the use of a hammer, or “dry”.
Advice. When cleaning a whitewashed surface, it is better to wet it, otherwise you may encounter a lot of dust.
Leveling and repairing ceilings in an apartment
After removing the previous finishing material from the ceiling surface, it is necessary to inspect it for damage, cracks and irregularities. All “problem” areas will need to be eliminated. To do this, you need to open the cracks using a spatula. After this, the damaged area is primed and puttied. This will only be enough for small cracks. If their depth is more than 3-5 mm, then you cannot do without a painting mesh. It will be hidden under a layer of putty and will provide additional reliability.
If rust was previously visible in a certain part of the ceiling, this defect must be eliminated. This can be done using a solution of copper sulfate.
Copper sulfate can also be useful for antifungal surface treatment. Just 70-100 grams of dry matter per 1 liter of water can protect the ceiling from many troubles and “diseases”.
Next you need to level the surface. This is done by priming and applying paint mesh. Next stage – putty, and the final chord will be grinding leveled surface.
All these recommendations must be followed strictly in any case: and when it is necessary to do perfect ceiling and in the event that you only need redecorating. Any, even the most minor, violations will be clearly visible on an already painted ceiling; impressions of the work done will be blurred, and the result will not be satisfactory.
Whitewashing the ceiling with your own hands: preparing a primer for whitewashing
After the surface is completely prepared, the final whitewashing of the ceiling begins. This can be done in several ways using a number of tools. The three most popular materials for whitewashing are chalk, lime or water-based emulsion. The final price will depend on the choice of material, but in any case it will be many times cheaper and more environmentally friendly than other methods.
When starting the final whitewash, you need to prepare a primer. It is made on the basis of slaked lime or from the remains of material from repair work. The soil mixture contains 200 grams of soap, 2 liters of water, 100 grams of drying oil and 3 kilograms of lime (slaked).
The soap is cut into small pieces or shavings and soaked in water until completely dissolved. After this, drying oil is added. In another container, prepare the lime by diluting the mixture in 4 liters of water. After this, the two resulting solutions are combined into one with the addition of 10 liters of water.
To obtain a homogeneous mass, it is necessary to strain the resulting solution through cheesecloth. After this, the mixture is applied to the ceiling using a brush, roller or spray. After completing the work, you must thoroughly rinse the instrument involved. Final stage – whitewash.
Advice. If it is not possible to purchase a compressor or spray gun, you can use a regular vacuum cleaner with a “blowing” function and a special nozzle.
Whitewashing with chalk or lime
Whitewashing using chalk or lime begins with preparing a solution. For chalk whitewash you will need 5 liters of water, 3 kilograms of chalk (or lime) and 20 grams of blue (ultramarine). All ingredients are mixed and filtered through cheesecloth to obtain a homogeneous mass. This amount of mixture will be enough for whitewashing surfaces of 10-12 m2.
Ultramarine (blue) is necessary in the solution to preserve the white color. If you neglect this substance, the ceiling will turn yellow over time.
For lime whitewash need to 3 kilograms of lime and 10 liters of water. It is also added here 100 grams of regular salt and 200 grams of aluminum alum. Preparing the solution may result in burns, so you need to be as vigilant as possible and wear gloves. It is better to wear glasses over your eyes and protect your mouth with a respirator. Important Feature whitewashing with lime - this method protects the surface well from the occurrence of various “diseases” - mold and mildew.
Whitewashing is easier and faster with a spray bottle. But, if this is not possible, you can do it with a regular brush or roller. To do this, the tool is moistened in the solution, squeezed a little to remove excess solution and carefully applied to the surface with direct movements away from the window. After applying the first layer, you need to wait a little, and apply the second layer perpendicular to the first. In this way, all the shortcomings will be corrected, and the ceiling will acquire a rich white color.
Whitewashing the ceiling with water-based paint +Video
The use of water-based paint for whitewashing is in many ways similar to the first method discussed. The only difference is in the method of surface preparation. Instead of a homemade soil mixture, a primer is used deep penetration. In addition, the use of water-based emulsion eliminates the need to dilute the lime-chalk solution.
Today, water-based paint “Snowflake” has gained great popularity.
