When carrying out repairs in an apartment, it is important to pay special attention to the ceiling. A smooth and even surface is able to emphasize the dignity of a room, filling the space with air and light, which are so necessary to create a cozy atmosphere. Among the variety of finishing materials used for the repair and decoration of ceilings, whitewash is in the lead in popularity.
The undoubted advantage is the material attractiveness of the process. In addition, many consumers make a choice in favor of whitewashing, focusing on its hygienic safety and harmlessness to health, as opposed to hanging structures, stretch ceilings or ceiling tiles.
The beautiful gloss of a freshly whitewashed ceiling goes well with any design solution of the room, visually expanding the space (read on our website an article about a beautiful ceiling with your own hands). And finally, whitewashing the ceiling on your own is quite a feasible task if you strictly adhere to the rules and instructions.
For whitewashing ceilings, chalk, lime or water-based paint are most often used. Most often, when choosing a material, they are guided by what the ceiling was previously treated with. In order to determine this, it is enough to run your finger over a dry surface: the lime wash does not smear, but the chalk will remain on the finger.
However, if you still have doubts, you can rub the ceiling with a damp hand - the lime will darken, but it will not remain on the skin, but the chalk will smear after your hand. It is not recommended to whitewash with chalk on top of lime, due to the possibility of the formation of numerous streaks and stains, which will entail repeated re-painting. Ideally, you need to paint the ceilings every one and a half to two years.
There are several types of emulsions:
- satin emulsion allows you to hide multiple defects of the ceiling surface due to the fact that the coating turns out to be somewhat glossy, depending on the emulsion marking, the degree of gloss can be different;
- matte emulsion has a denser texture, which makes it possible to hide more significant surface imperfections, but it dries much longer;
- special types of emulsions designed for kitchens or bathrooms have enhanced moisture-resistant and bactericidal properties.
Another argument in favor of chalk or lime is that when whitewashing with these materials, it is not necessary to pre-prime the ceiling.
Tools required for work
You can whitewash the ceilings either with a roller or with a brush. These methods are optimal for apartments and small country houses and premises.
Whitewashing using a spray gun is more laborious and costly, requires skill and ability to work with the unit, in addition, when whitening with a spray gun, a large amount of splashes is created that can interfere with work.
So, to carry out whitewashing work yourself you will need:
New brushes should be soaked whole in warm water for several hours before use. Brushes prepared in this way will not "lose" bristles during work. It is recommended to choose natural stiff bristles with a width of 12-15 cm.
The rollers are selected individually based on personal preference. The main thing is that a previously unused tool is used for whitewashing, in order to avoid defects and blemishes in the coating.
Dilution of water-based paint is most often not particularly difficult, which cannot be said about the preparation of a chalk or lime solution.
The solution is prepared from the approximate calculation that for each square meter of the ceiling painted in one layer, half a liter of the mixture will be required. But most often the component compositions are given on an area of 10 sq. m. The finished mixture can be stored for no more than 36 hours, and dry ingredients - for several years without spoilage and loss of their properties and qualities. If possible, the mortar is mixed using a construction mixer.
To prepare a chalk solution, you will need from 30 to 100 ml of glue (PVA or carpentry), rubbed on a fine grater to laundry soap weighing 50 g, as well as 3 kg of chalk sieved through a sieve (sifting is a necessary step to remove garbage and the largest particles from the whitewash material) and 10-20 g of ordinary blue to enhance the whiteness of the color and prevent possible yellowing of the coating.
First, soap chips and glue are dissolved in warm water, then chalk, previously mixed with blue powder, is poured in a thin uniform stream with constant stirring.
The lime mixture is prepared somewhat easier: 1.75 g is diluted in warm water pure lime, 100 g of table salt and 40-45 g of blue. However, such a mixture does not give saturated white light, making up for it with its masking properties.
The amount of water is taken arbitrary. Approximately 1 kg of chalk or lime requires 2 liters of warm water. To determine the optimal consistency of the mixture, they use this technique: a metal object with a smooth surface (a pin or a knife) is vertically lowered into the solution, if, when pulled out, the mixture flows down without leaving traces, the solution is not thick enough and chalk or lime should be added. In this case, the concentration of the mixture is increased gradually, after each addition, the quality of the solution is checked.
The finished mixture is left for 10-15 minutes, after which it is filtered through a sieve or a layer of rags. A well-prepared mixture has no lumps and, when flowing down, paints the metal white. Immediately before the whitewash itself, the solution is mixed well.
Before whitewashing, the room must be freed as much as possible: take out all the objects, dismantle the cornices, chandeliers and other lighting fixtures. Large-sized furniture and built-in items and decor elements should be well covered with plastic wrap and pasted over with tape. It is necessary to lay the flooring with special care - this will significantly save cleaning time later.
The floors can be covered with old newspapers or sheets in several layers, the baseboards can be pasted over with masking tape. Close the skirting boards and moldings if necessary.
Ceiling preparation. Step 1. Removing the old whitewash
Even if the old whitewash is not cracked and looks quite clean, it is better to remove it. To facilitate this task, there are special solutions, but you can use proven methods - warm water or a mild soapy solution and a spatula.
Before starting work, you need to protect your face, body and hands with protective equipment. Lime or chalk has a detrimental effect on unprotected skin and is not easily washed off the hair.
Whitewashing is a painstaking and time-consuming process, depending largely on the nature of the whitewash mixture. The chalk layer is easier to clean off than the lime layer.
How to remove old lime wash?
Most often, it is simply scraped off the ceiling with a metal spatula, after tapping the area to be cleaned with a rubber mallet. It is ineffective to soak the lime whitewash, as the old layer will clump and smear on the ceiling.
There is a known method of cleaning a ceiling plate using paste, when the entire surface is densely covered with a solution, and then it is cleaned off with a spatula along with whitewash.
How to remove chalky whitewash?
A layer of chalk is removed from the ceiling with hot water with the addition of 3% acetic acid and a sponge (it is permissible to use a separate roller with a long handle). The thoroughly moistened stream is left for half an hour to swell the whitewash layer, and then carefully removed with a spatula. If the layer is not swollen enough, the ceiling is moistened again.
Chalk on problem areas should be rubbed with a sponge. And at the end of cleaning the ceiling - let the surface dry. The degree of cleanliness is checked by the presence or absence of white marks on the palm when touching the ceiling.
Step 2. Cleaning, unevenness correction and priming
When the old layer of whitewash has been removed, the ceiling must be cleaned of stains, traces of grease or rust, mold and mildew, if any.
Rust marks and smudges can be easily removed with warm salt water and a sponge. It is advisable to treat the dried up place with a solution of copper sulfate (75 g per 1 liter of water).
Old traces of fat are cleaned with rags dipped in a solution of calcined salt, which is sold in household departments. After removing the stain, the area should be rinsed with water.
If the joints of the slabs on the canvas cause concern, they can be glued with a serpentine - it will preserve the integrity of the coating from cracking. Cracks, depressions and cracks must be putty. Homemade glue putty is best for fixing defects in ceiling tiles - it holds well and is easy to apply.
To obtain it, you will need two parts of wood glue and gypsum and one part of sifted chalk. The mixture is mixed with water and applied to the ceiling with a spatula. After drying, the surface is rubbed with sandpaper until smooth. The ceiling prepared in this way is primed - this will give the surface additional moisture-proof properties and facilitate the whitewashing process itself. The primed ceiling is left to dry for 24 hours.
Step 3. Whitewashing
With a well-prepared ceiling, two layers of whitewash are enough. You should start from the corners, mentally dividing the ceiling into sectors. It is most convenient to start from the window, gradually moving towards the door. When carrying out work, it is very important to eliminate drafts, otherwise the whitewash may crumble.
Each layer of whitewash must be well dried and only then proceed to the next. There are also some nuances when whitewashing with various tools.
Roller whitening is preferable as it provides the best results, even in the absence of experience. Using the roller, you can follow a V-shaped motion for even painting. And you can apply multidirectional layers: the lower one is perpendicular to the window, and the upper one is parallel, carefully rolling the roller over the surface. This will help avoid divorce. The width of the overlap between the strokes should not be less than 5 cm.
It is important to ensure that no sagging or dripping occurs. To do this, excess whitewashing solution from the roller should be removed by rolling the roller along the inclined part of the cuvette.
Hard-to-reach areas and corners are painted over with a medium-sized brush.
Whitewashing with a brush is a more painstaking and lengthy process. The principle is the same - work begins from the window with short strokes, layers are applied in different directions with an interception width of 5-6 cm.
Whitewashing the ceiling is a laborious process, but quite feasible on its own.

Whitewashing ceilings with lime or chalk refers to the classic and well-proven methods of updating them, allowing you to quickly organize redecoration of a particular room. In comparison with modern techniques for decorating ceilings (arrangement of tensioning systems, for example), this method of finishing ceiling surfaces is the most simple and inexpensive.
When preparing for work, you are directed to decide on the source material, on the basis of which you will begin to prepare the finishing composition (lime or chalk).
And, of course, any of these materials has its own characteristics. Lime, for example, has the ability to tighten microscopic cracks, making the ceiling surface smoother and smoother. For its part, the chalk solution makes it possible to acquire a coating of perfect whiteness. So, when choosing this or that material, you should be guided, first of all, by your preferences.
In our article we will consider the technology of whitewashing preparation based on both of these components.
Preparation of lime wash
You may need the following components to prepare a lime-based finishing compound:
- slaked lime;
- pure water;
- drying oil;
- 50 grams of table salt;
- a bag of blue or ultramarine.
Before diluting lime to whitewash the ceiling, you will need to prepare 2-3 kilograms of starting material and 5 liters of hot water. The required volume of the finished composition is determined in most cases from the calculation that for every 2.5 m? the surface to be treated consumes approximately half a kilo of lime and 0.75 liters of clean water.
To obtain the optimal composition, we first dissolve slaked lime in the prepared water, and then we successively add all the auxiliary components in that direction. To give the finished whitewash additional plasticity and durability, add a little drying oil (one third of a tablespoon) and about 5 grams of table salt to the mixture. Then the finished solution is well mixed, and after that it is immediately filtered through a sieve, which allows you to remove large lumps of lime and other impurities from it.
Note! To give the ceiling whitewash a light bluish tint, 20 grams of blue is added to it, which will provide the ceiling with additional attractiveness in natural light.
Before diluting chalk for whitewashing, you are directed to familiarize yourself with one of the options for making it, for the implementation of which you will need:
- dry chalk;
- blue;
- container with warm water;
- simple gauze.
The procedure for working with chalk whitewash involves the following steps:
- First of all, you need chalk, available as a thick paste (dry powder) at any hardware store. You should not be confused by the event that the acquired chalk paste has a slightly grayish tint; some time after the end of the whitewash, the coating will necessarily buy the whiteness characteristic of chalk.
- The amount of starting material required for work depends on the size of the treated room and the density (consistency) of the prepared solution. Try to buy a small stock of chalk paste; along with this, unused leftovers will always be useful to you in subsequent repairs.
- Before starting whitewashing, it is essential to test the technique of applying the finished composition on a small area of the surface to be trimmed (make a trial attempt). That is why you can buy at least some skill of working with whitewashing, and find out the approximate consumption of the solution.
- Before preparing the whitewash, be sure to sift the purchased chalk powder, which will allow you to clean it of unwanted impurities and large fragments. After that, take about 2 kilograms of chalk and dilute it in 2.5–3 liters of warm water. Stir the mixture whisperingly until a homogeneous composition is formed that does not contain lumps visible to the eye.
- Strain the finished composition through cheesecloth, laid in two or three layers, periodically rinsing it with clean running water. As a result of the operations performed, you must take a ready-to-use mass that resembles liquid sour cream in its consistency.

Whitewashing walls with lime is a well-known procedure for many people in the street. It enjoys well-deserved confidence due to the fact that such a coating is breathable and has an antiseptic effect.
You can do the work yourself, without involving specialists, and all the necessary materials do not require significant material costs. To get a high-quality coating, you need to know some of the features and subtleties of preparing the composition.
It is important to apply it correctly to the prepared surface. Before whitewashing ceilings or walls, you must choose a base for preparing the solution. It can be chalk or lime.
Lime resists the development of fungus Despite the fact that the use of chalk is the easiest and most affordable way to prepare a composition for whitening indoor surfaces, lime is in great demand. This is due to the fact that the walls and ceilings treated with lime whitewash are not susceptible to the formation of mold and mildew. The most popular composition for whitewashing walls is fluff. White powder, quenched and ready for use after adding water and fixing agents.
Modern manufacturers sell lime:
- Slaked, supplied to the place of sale in the form of powder or paste (dough).
- Quicklime, sold in the form of granules or large lumps.
After pouring lime with water, close the container with a lid. For whitewashing, only slaked lime is used, for the preparation of which you will need:
- water and lime itself, taken in a 1: 1 ratio;
- clean metal dishes without chips and corrosion;
- cover for the container;
- wooden spatula for mixing the solution.
After the quicklime is poured with cold water, it begins to boil, heating up to 130 ° C. The reaction is very violent, the liquid bubbles and splashes scatter in different directions. At this point, it is better to cover the container with a lid to avoid getting the mixture on bare skin.
You cannot use plastic dishes, since the solution gets very hot during the quenching process, and you can mix the composition only after the reaction is complete. Now the container needs to be closed with a lid and removed to a cool, dark place for 20-25 days.
At the end of the specified time, the composition is thoroughly mixed.
Achieve complete dissolution of the granules A thick white film should remain on the wooden spatula. The mixture required for whitewashing is diluted with cold clean water, achieving a homogeneous opaque composition. The approximate amount of a ready-made solution prepared from 1 kg of quicklime is 10 liters.
During quenching, all lumps and granules must completely dissolve in water, but before use, the contents of the container must be thoroughly mixed, and strain through a special mesh before use.
The tool for performing bleaching can be selected taking into account the wishes of the layman or the characteristics of the surface to be treated:
- spray gun.
When working with a spray gun, the resulting mixture will have to be filtered through cheesecloth to remove even the smallest remaining lumps.
How to increase the durability of the solution
Soap will give the solution durability To whitewash the walls with not only a high-quality, but also a durable solution, you will need to introduce some special additives into it. You can use regular laundry soap or wallpaper glue. Whitewashing lime is used for application to facade walls.
In this case, it is necessary to protect the composition from the negative effects of precipitation and rapid flushing. You can do this by introducing drying oil into the solution, which will repel moisture and help whitewash, to remain on the walls as long as possible.
The introduction of some additives into the whitewash composition will avoid lime shedding from the walls.
Lime-whitewashed surfaces tend to stain everything that touches them. You can avoid this by adding ordinary table salt to the solution.
Knowing the proportions allows you to achieve the desired effect:
- lime and salt - 1 kg per 10 liters of solution; salt will help to make the surface snow-white;
- drying oil - 100 ml per bucket of whitewash;
- Laundry soap, rubbed on a coarse grater, is poured with hot water, and then, during the preparation of the bleaching mixture, soap solution is added instead of water.
Sometimes masters advise, instead of a small portion of PVA or wallpaper glue, to introduce joiner's glue into the solution. It is boiled in a steam bath and, before whitewashing the walls, is added hot to the prepared lime whitewash. For more information on how to whitewash, see this video:
Easy to apply whitewash with a roller
One of the most popular recipes for making a bleach composition:
- 5 kg of slaked lime;
- 100 g of crushed and brewed laundry soap;
- 50 g of wood glue;
- 10-15 g of powder for linen blue;
- 8 liters of clean cold water.
Having mixed all the named ingredients, they are poured with water, mixed thoroughly and allowed to brew for 5-10 hours. It can be applied to the surface using a roller, a special bleaching brush or a wide paint brush (maklavitsa).
Before you whitewash the wall with lime, you should make sure of its integrity, the absence of cracks and cracks. A thick lime whitewash will easily hide a microcrack on a putty surface, but larger ones must be eliminated before starting work.
Work order
In some cases, the whitewash can be sprayed onto the walls. Whitening does not take much time and does not take a lot of energy from the layman if it is done in accordance with the existing rules. First of all, it should be said about the need for preparatory work. All walls and ceilings that are planned to be whitewashed must first be putty by putting putty in two layers.
After complete drying (after 12 hours), you can proceed to the surface with sandpaper. In the event that wood glue or PVA was introduced into the whitewash mixture, priming of the walls is not required. Whitewashing will last for at least 5 years, without cracking, not crumbling, without staining the hands and clothes of the residents. For more information on a quick way to whitewash, see this video:
In order for the walls to be painted with high quality, cover them with two layers of lime The composition is applied in two layers with complete drying. Wait at least 5 hours before proceeding with the re-bleaching. A properly prepared solution does not leave noticeable transitions and traces (streaks) from a brush or brush.
When working with a spray gun, it is important to prepare a mixture of the correct consistency and not to spray it from a short distance. This way you can avoid streaks and achieve an even distribution of the whitewash over the surface.
In order for all layers to be of the same quality, you will have to constantly stir the contents of the container, preventing sediment from forming.
You can quickly, simply and cheaply finish the ceiling by whitening it. For the result to be satisfactory, you need to take into account all the features of the process, starting with the preparation of the solution. The quality of the layer depends on its composition, color intensity and consistency.

Whitewashing is a budget and simple finishing option, which, in addition to all its advantages, has a significant drawback - fragility. The whitewash quickly crumbles, fades, loses its aesthetic appearance. In order for the finishing layer to look attractive and last as long as possible, you need to be able not only to correctly apply the whitewash composition, but also to prepare it.
Types of whitewash compositions for the ceiling
Today there are two main types of solution for whitewashing the ceiling:
- Cretaceous... It is hygienic, has a deep whiteness, but crumbles rather quickly.
- Lime... It has bactericidal properties, crumbles less, but it can dry the air in the room and can cause allergies.
Lime and chalk can be purchased in dry or pasty form. For high-quality whitewashing, you can use both options. Most recipes also include additional ingredients.
Preparation of a chalky solution for whitewashing the ceiling
There are several recipes for preparing this composition. In addition to the traditional ingredients, you can add different colors to add the desired color to the ceiling.
Concentrated dry chalk solution for ceiling
Before you dilute the chalk to whitewash the ceiling, you need to stock up on laundry soap, wood glue, ultramarine or color scheme.
We adhere to the following instructions:
- Sift 3 kg of dry chalk powder and pour into a container.
- Pour 3-3.5 liters of warm water.
- Add 50 grams of laundry soap shavings and 100 grams of wood glue.
- Dilute ultramarine in a separate vessel with warm water.
- When you get a shade of the desired intensity, pour the blue into the solution.
- Thoroughly mix all the ingredients until a uniform shade and filter through double gauze or nylon.
The consumption of this solution is 0.5 liters per 1 m 2.
White dry chalk for ceiling
This composition will be enough to whitewash 20 m 2 of the ceiling.
We cook it in this order:
- We heat 10 liters of water to a temperature of + 40-45 degrees.
- Dissolve 120 grams of wood glue and 150 grams of laundry soap shavings in it.
- Mix thoroughly and add 6 kg of dry chalk, which had to be sieved beforehand.
- We add water, bringing the composition to a volume of 20 liters.
- Dilute ultramarine with water in a separate vessel.
- Add blue to the solution to avoid yellowing the layer.
Composition of chalk paste for whitewashing the ceiling
To make a solution of pasty chalk for whitewashing the ceiling, you will need CMC wallpaper glue. We carry out the work in the following sequence: dissolve the glue in warm water so that a 1.5% solution is obtained, mix the glue mixture with chalk paste in a ratio of 4 to 1. This composition does not need to be filtered, it is immediately ready for use.
Preparation of lime mortar for whitewashing the ceiling
Lime for whitewashing the ceiling, like chalk, is sold dry or already slaked. Dry lime, depending on the slaking speed, is of three types: quick-quenching - 10 minutes, medium-quenching - 20 minutes, slow-quenching - more than half an hour. The slower the lime is extinguished, the smaller portions you need to add water. The composition for whitewashing the ceiling is prepared from slaked lime. If you only have dry, then you can repay it at home.
Lime slaking technology for whitewashing the ceiling
To carry out this procedure at home, you must first put on safety glasses, a respirator and work clothes.
We carry out work in this order:
- Pour lime into a metal container without rust.
- Pour cold water in a ratio of one to two.
- Stir lime and dilute with water to the required viscosity.
- We leave to stand for several days.
During the process, it is very important not to lean over a container with slaking lime, as very caustic steam is released.
Lime and aluminum alum solution for ceiling
To dilute properly slaked lime, we need salt, a dye (you can use ultramarine), 200 grams of aluminum alum.
Cooking in the following sequence:
- We dilute 3 kg of slaked lime in 1 liter of water and mix until smooth.
- Soak 100 grams of salt in a separate bowl.
- Add 200 grams of aluminum alum and soaked salt to the solution.
- Mix all the ingredients thoroughly and pour in 0.5 kg of dye.
- We bring the composition to a volume of 10 liters with warm water.
So that no streaks remain during lime whitewashing, it is recommended to pre-wet the coating with water.
Composition of slaked lime and glue for whitewashing the ceiling
To prepare this solution, you will need slaked lime, laundry soap, wood glue, ultramarine, table salt.
We dilute the mixture in this order:
- Dissolve 6 kg of slaked lime in 8 liters of water.
- Add 100 grams of laundry soap shavings.
- Separately dilute 200 grams of wood glue in water and dilute with a common solution.
- Thoroughly mix the composition and add ultramarine until a shade of the desired intensity is obtained.
- Add 200 grams of ordinary kitchen salt, which we dilute in water beforehand. This will make the mixture more stable.
Waterproof lime whitewash solution for ceiling
This mixture can be made from slaked lime, water, drying oil and salt in the following sequence:
- We dilute 400 grams of lime in 0.6 liters of warm water.
- Add 1/3 tbsp to the composition. tablespoons of drying oil and the same amount of kitchen salt.
- Stir the solution thoroughly until a uniform consistency and shade is obtained.
- We filter the composition to remove excess lumps. The consistency of lime white should be like thick milk. Whitewashing with such a mixture will last for a long time and have a high moisture resistance.
Lime and chalk solutions for whitewashing have their own characteristics. However, in order for any finishing layer to be qualitatively and evenly adhered to the surface, you need to understand the main issue - how to dilute lime to whitewash the ceiling or chalk. Our recommendations will help you choose the best method. From the proposed methods, you can choose the one that is most suitable for finishing the desired surface.
There are many options for decorating the ceiling, but one of the easiest and most inexpensive ways is to whitewash the ceiling with chalk. If you correctly approach the solution of the issue, the result is an even snow-white ceiling. To do this, it is imperative to remove the old layer and level the surface (putty, prime).
Preparing the ceiling for whitewashing
We perform surface cleaning
Do-it-yourself whitewashing of the ceiling with chalk is quite real! The technology does not imply any complex actions, so almost anyone can handle it.
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 pretty dusty. The following recommendations will be useful to you:
- if possible, take the furniture out of the room where the work is being done;
- cover the floor and the rest of the furniture with foil;
- buy rubber gloves, glasses.
There are several ways you can remove chalk from the ceiling:
- dry cleaning (old whitewash is scraped off with a spatula; sometimes a paste solution is pre-applied and left to dry completely);
- erosion of the whitewash (it is gradually washed off with a brush or a hard cloth soaked in water);
- mixed method (a small area of the surface is sprayed with a spray gun, then a scraper is used to remove the whitewash, a wet rag);
- soap solution (dilute 2 tablespoons of laundry soap in 10 liters of warm water, add 5 tablespoons of soda; the solution is applied with a sponge, the soaked layer of whitewash is carefully removed);
- using a sander (involves a lot of dust).
Then the cleaned surface should be putty and primed.
How to putty the ceiling
You can prepare a mixture for putty yourself:
- Dissolve the wood glue (for 50 g of glue you need 1 liter of water).
- Combine glue, chalk and plaster (in a 2: 2: 1 ratio).
- Stir until smooth.
- Apply to the ceiling.
Also, for the preparation of putty, you can use this recipe.
- Dilute slaked lime with water (2.5 kg per 5 liters of liquid).
- Enter table salt (4 tablespoons is enough), add water so that the total volume is 10 liters.
- Knead chalk (200 g) with glue (10%, 1.5 L) separately.
- Knead each mixture, combine.
- Apply plaster to the ceiling.
A small amount of the mixture must be taken with a spatula, spread over the ceiling. The tool should be held at an angle so that the filler is applied evenly. After the first layer has dried, you can repeat the procedure. Try to smooth out the edges at the junction of the layers right away, otherwise it will be difficult to do after drying.
How to prepare a primer
After plastering, the ceiling must be primed. For this it will come in handy:
- 50 g of drying oil;
- laundry soap;
- 3 kg of slaked lime.
First, you should grate the soap on a coarse grater, dissolve it in hot water. Then enter the drying oil. Dilute lime separately with water, combine soapy water with lime solution. The total volume of the mixture must be brought to 10 liters with water. Knead the mortar out with your hands and apply to the ceiling with a roller.
If you do not want to waste time preparing the primer, you can purchase a ready-made mixture at a hardware store and simply dilute it with water, following the instructions on the package.
How to dilute chalk to whitewash the ceiling
Whitewashing solution can be purchased ready-made, or you can prepare it yourself. The average consumption of raw materials is 0.5 liters of solution per 1 sq. To make a solution for whitewashing, you can use: lime, chalk, blue, wood glue, chalk paste.
One of the simple recipes is the following. Sift chalk, remove impurities, large particles. Pour 1.5 kg of chalk into a deep bowl, pour 2.5 liters of water and 30 g of wood glue to it (it can be diluted with a little hot water).
Stir well so that there are no lumps left and the mixture is completely homogeneous. Then the solution must be filtered through cheesecloth, folding it in 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 greatly facilitate your task.
The ideal concentration of whitewash is one in which an object, dipped into a solution, is colored evenly, while an even trickle flows from it. If you get a thick mixture, it can be diluted with water, if it is liquid, you need to let the solution brew and drain a little water.
How to whitewash the ceiling with chalk
You need to start whitewashing from the window deep into the room. This will avoid unsightly shine on the surface. When the first layer dries up, 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 to reduce the number of streaks). If you are working with a roller, it is advisable to brush the corners so that an even layer is obtained everywhere.
When all the work is finished, it is necessary to exclude drafts until the ceiling is completely dry, as this can worsen the quality of the work. You should also protect the whitewash from direct sunlight, otherwise it may crumble.
It is important to remember that when reprocessing the ceiling, it is advisable to use the same materials (lime or chalk mortar) as in the previous time, so as not to get streaks. How do you determine which solution is applied to the ceiling? It's very simple: slightly dampen the surface and watch the whitewash reaction. If the fingers get stained, chalk was used. If the surface darkens and the fingers remain clean, lime was used.
The whitewashed chalk ceiling will fit perfectly into any interior. She looks very neat, gentle, acts as a background for decorative elements. Do not think that a whitewashed room will be boring, dull, out of date. Add bright juicy colors to the interior, stylish accessories - and you will see how the ceiling will emphasize the overall design idea.
