Whitewashing the ceiling with a roller: 5 detailed steps

How to whitewash the ceiling

Before whitewashing the ceiling, many people ask a question that relates specifically to the choice of material. In many construction portals, whitewashing is done using water-based paint. The issue is controversial, because water-based emulsion belongs to the category of paint and varnish products. Therefore, when it is used to decorate the ceiling plane, they say - painting the ceiling. That is, this material has nothing to do with whitewashing.

Although the word “whitewash” comes from the word “white”. And since water-based paint is mostly white, hence the confusion. And yet we insist that the process of applying paint to the surface being processed is called “painting”.

So what materials can you use to whitewash the ceiling:

aqueous solution of slaked lime;
aqueous solution of chalk.

The first material is moisture resistant, perfectly hides minor defects in the ceiling surface, and has bactericidal properties, so whitewashing wet rooms is a priority. The disadvantage of lime mortar is allergenicity. Not all people can tolerate it, so this point must be taken into account. The second disadvantage is the unpleasant odor during use. But it disappears as soon as the ceiling dries.

The second material, that is, chalk whitewash, has a deeper and richer white color. It has all the same characteristics as lime, but chalk is hypoallergenic, plus it meets all the requirements of sanitary and hygienic standards.

Now about how to prepare both solutions for whitewashing. In fact, it is not so simple, because there are no specific recipes, so the masters mainly prepare them by eye, and each of them has their own proportions for mixing the ingredients. But there is an approximate consumption - this is 0.5 liters of mixture per 1 m² of ceiling surface. Typically, the components of the solution are combined per 10 m².

Attention! Remember that either of the two solutions can be stored for no more than 36 hours.

So, how to prepare lime mortar:

slaked lime is rubbed through a fine sieve, there should be no lumps or pebbles;
1.75 kg of material is poured into warm water and mixed thoroughly; you can use a construction mixer or a drill with a special attachment;
100 g of table salt and 50 grams of blue are poured here;
All this is thoroughly mixed until a homogeneous mass is obtained.

It should be noted right away that the lime mixture will not give a rich white color for the ceiling. But its superiority over chalk whitewash is its high masking qualities, with the help of which small cracks are whitened.

Now about how to properly prepare a chalk solution:

the chalk will also have to be sifted through a sieve, 3 kg will be left;
you will need glue: PVA or carpentry glue at the rate of 30-100 ml;
as well as laundry soap, which is ground on a grater, you will need 50 g of material;
and lastly - 10-20 g of blue.

The preparation process is as follows: first, laundry soap is dissolved in warm water, then glue is added, and lastly chalk mixed with blue. The latter is added in small portions. The whitewash for the ceiling is ready.

And the last thing is the amount of water. Here the average calculation is as follows: for 1 kg of base material, 2 liters of water.

Now about how to determine whether the whitewash was prepared correctly. To do this, you will need either a knife or any metal pin with a smooth surface, for example, a long nail. The selected instrument must be vertically immersed in the prepared solution and pulled out. If the glass mixture does not leave any traces, it means it is not thick enough. What to do - add chalk or lime. It should be understood that the main material is added in small portions, and a check is made after each batch.

The video shows the technology for preparing chalk whitewash:

Second position. If, after removing it from the prepared mixture, there are lumps or the whitewashing material left on the testing device, it means that the prepared solution is too thick. You need to add water to it. And here everything is exactly the same - water is added in small portions, and after each batch a check is made. In both the first and second cases, it is necessary to ensure that a thin white layer remains on the metal surface. And the metal would not be visible.

If the solution for whitewashing the ceiling is ready, it must be left for about fifteen minutes so that it “reaches.” The mixture is then passed through a fine sieve. And just before whitewashing, it is mixed again.

So, we figured out how to whitewash the ceiling and how to prepare solutions. Now let’s move directly to the topic of the article, namely, how to whitewash a ceiling.

Preparation of whitewash solution

There are two types of lime - slaked and quicklime. They are completely different substances not only in their structure (quenched - powder, quicklime - lumps), but also in chemical composition. Quicklime cannot be used for whitewashing, but you can prepare slaked lime from it yourself, which is then added to the solution.

Before starting work, take all necessary precautions. The process of slaking lime is an intense chemical reaction, accompanied by copious amounts of heat, which can cause burns and damage to the respiratory tract. Therefore, work should be performed only with gloves, safety glasses, a respirator, and clothing that completely covers all exposed skin.

Quicklime is poured into a metal container, into which cold water is added in a ratio of 1 liter of water per 1 kg of lime. The water will immediately react, which will be accompanied by the release of heat, hissing and splashing. After about half an hour, the reaction will begin to subside and the solution can be mixed well. After this, the water should completely evaporate, and the remainder will be slaked lime powder. You can use it at least after a day, waiting for it to dry completely.

You can make slaked lime yourself or buy it at a hardware store. To prepare whitewash for 10 liters of water, you will need 3 kg of lime powder, 100 g of table salt and 20-40 g of blue. The consumption of the solution depends on the type of surface being treated and the tool used. When working with a brush or roller, the consumption is about 0.5 liters per square meter of a flat surface or 1 liter per square meter of a brick wall.

Spraying the solution with a vacuum cleaner or spray gun slightly reduces the consumption, but the thickness of the applied layer decreases.

How to whitewash a ceiling

When the renovation reaches the ceiling. The most interesting question is to stretch or whitewash? A stretch ceiling allows you to give free rein to your imagination; it can be ordered in any color, texture, with or without a pattern, made multi-level, and installed with built-in lamps. but the main thing is that you don’t need to worry about preparing the surface. However, the good old whitewashing of the ceiling also has its advantages!

For example, if you need to renovate a room quickly and inexpensively, or if you prefer environmentally friendly materials, whitewashing the ceiling is an ideal option for you.

Benefits of whitewashing the ceiling

Environmentally friendly material, absolutely safe for humans;
Lime whitewash has disinfecting properties;
The ceiling covering becomes moisture resistant due to the small pores that form when whitewash is applied correctly;
Whitewash is resistant to abrasion;
The whiteness of the ceiling, depending on the solution used, will last from two to four years;
Cost-effective option.

Whitewashing the ceiling with a roller yourself is very simple. Even a beginner in the construction business can do this. It is very important to properly prepare the ceiling, use a foam roller to apply the whitewash, and constantly stir the solution during application.

Different methods and their differences

Lime whitewashing may be the most budget-friendly way to give your ceiling surface a fresh look. But there are also some difficulties, especially in terms of preparing the solution, the desired composition and consistency.

There are several points that present some difficulty for a person who has never encountered such dyes. The easiest way is to buy a dry concentrate of such whitewash, ready for dissolution.

Chalk solution . It is easier to prepare, but there are also some nuances in its production. Fewer ingredients will be needed, and the process of creating the solution itself is easier to control than in the case of lime.

It is advisable to use both of these options in cases where the previous coating was made using such solutions. Moreover, it is undesirable to apply chalk coating to a lime coating, and vice versa.

Water-based and water-dispersion paints. Everything here is much simpler than with self-prepared chalk or lime solutions. Paints, as a rule, are sold ready-to-use, and the most that needs to be done with them is to dilute them a little with plain water.

Possibility of sharing

A priori: a brush and a roller can be used when working on separate parts of the same object. There is no contradiction between these instruments; on the contrary, they complement each other well.

Application of rollers

As already mentioned, a paint roller is a flat tool . Its task is to paint large surfaces; in relation to ceilings, these are primarily plasterboard and plastered ceilings, previously well-primed and puttied for painting (it is best to use fiberglass to avoid cracking). Small rollers are also good for painting wide ( from 150 mm and wider ) ceiling, window and door slopes.

Using brushes to paint ceiling elements

No matter how good and effective a roller is, there are places that are inaccessible to it or where painting, although possible using a roller, is ineffective. These include:

Areas where the ceiling meets the walls, corners.
Narrow ceiling slopes (for example, differences between levels of a multi-level plasterboard ceiling).
Niches in the ceiling (for placing lighting and hidden ceiling cornices).
Elements of stucco decor: ceiling cornices and moldings, rosettes, caissons, etc.: it is in principle impossible to paint these elements efficiently without using a brush.

In some cases, brushes are also used to paint the ceiling plane : wood, concrete, etc. to create a deliberately roughly painted surface - similar decoration techniques are often used in loft and vintage styles. It turns out that a perfectly evenly painted surface is not always needed; some trends in interior design, on the contrary, require the creation of “brutal” textures (when painting wood with a brush, you should work in the direction of the grain).

A brush and a roller can and should be used together when painting ceilings; the question is “which is better?” there is no clear answer: it all depends on the stylistic solution of the interior, the design of the ceiling and the specific element that is to be painted; the main thing is to choose the right tool for a particular operation.

Benefits of whitewashing

Do-it-yourself whitewashing is a cheap and quick finishing method. Some consider it a relic of the past. However, a number of advantages make whitewashing very popular today:

A simple process algorithm. I follow fairly primitive rules; you can do everything yourself;
Availability. Materials and technical equipment are cheap and readily available;
Environmentally friendly. This method of surface treatment is rightfully considered the most hypoallergenic and clean;
Beauty. The color after this treatment is even, white and pure;
It has a pronounced bactericidal effect, thereby preventing the formation of mold;
Water resistance. Condensation cannot damage the whitewash layer or cause color changes.

This method of surface treatment is rightfully considered the most hypoallergenic and clean.

Advantages and disadvantages of lime whitening

In addition to the low cost, whitewashing the ceiling with lime is easy to perform and promotes the formation of a durable film that is resistant to abrasion and has disinfecting properties. If the solution is prepared correctly and the technology for its application is followed, the finish will not require updating for 3-4 years. Other benefits of lime whitening include:

obtaining a vapor-permeable surface;
fixing small cracks and defects.

Among the disadvantages of this finishing option are the possibility of streaks appearing when applying the solution and the ability to reduce the humidity level in the room.

In addition, whitewashing with lime is contraindicated in case of allergies and can cause irritation of the skin and mucous membranes. When performing it and preparing the composition for treating the ceiling, you must:

use a respirator, protective mask or wet bandage to prevent lime particles from entering the respiratory tract;
carry out all work wearing rubber gloves and comfortable clothing.

To protect the eyes from damage from lime mortar during repair work, special glasses are used.

Tools for whitewashing

Before whitewashing the ceilings yourself, prepare the necessary tools - this work is performed in one of three ways, for which they are used:

roller;
sprayer, also known as a spray gun;
brush.

If painting is carried out 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 whitewash brush can be purchased at any building materials store at an 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.

Difficulty of choice

Naturally, when choosing a brush or roller for painting work, you should choose only high-quality and professional tools. In order to whitewash the ceiling in a utility room, of course, you can save money and buy a cheaper tool.
However, if you are going to paint or whitewash a living room, office or a high-traffic area, it is better to opt for a high-quality roller or brush. There are several reasons for this:

When painting, a low-quality brush is almost guaranteed to leave lint on the walls. The same applies to rollers. In some cases, especially when using thick glazes, enamels or water-based paints, a problem with the quality of the coating is noticed too late to be able to change it. As the paint dries, it loses volume and air bubbles, protruding fibers or hairs begin to appear on the surface. It is better to immediately opt for a reliable brush or roller, so as not to encounter unexpected additional costs.
Painting or whitening surfaces with professional tools is much more pleasant, faster and more convenient than using cheap analogues. Expensive brushes and rollers allow you to paint in a thick, even layer. This has an effect not only on the appearance of the ceiling or walls, but also on the life of the coating and its resistance to external factors.
When painting, each task has its own specially designed roller or brush. Proper use of the tool will save you from large losses of paint that may fall on the floor, improve the quality of the finish, reduce material consumption, and help you complete complex painting work even without preparation.

Both tools can be used for painting work

What can be used as a tray?

In fact, a tray is not a complex high-tech device that cannot be replaced with anything. This is a common form, with an incredible number of analogues. For example, a regular food container (large size) can be used as a replacement. The most important thing is that the roller fits into it.

Or you can take a square-shaped basin. Basically, almost any waterproof object that is square or rectangular in shape will do.

Important: Before you start painting, you need to rinse the roller thoroughly, because it may contain various contaminants or unnecessary substances that will end up on the wall in the future. Few people want to redo all the work because of their inattention to detail.

Required Tools

In order not to rush around looking for the right tool while working, prepare everything in advance. You will need:

wide brush (15 cm) or roller;
narrow brush (5-7 cm);
plastic containers;
stepladder or table;
latex gloves;
old newspapers, rags.

Depending on the situation, you may need:

spatulas;
sponges;
serpyanka;
sandpaper.

Roller for painting

Due to the rapid development of various technologies, it is now perhaps difficult to find a master who uses brushes to paint walls. This outdated tool has long been replaced by more convenient and practical rollers.

The roller is a metal or plastic handle with a cylindrical attachment. Depending on the purpose of the tool, the nozzle can be made of the following materials:

Polyacrylic.
Polyester.
Foam rubber.
Fur.
Velours.

The first two materials are distinguished by their versatility and high wear resistance. They can be used for almost any paint. Such rollers are easy to use, distribute material over the surface as economically as possible and are easy to clean.

When working with water-based adhesive compositions, it is best to give preference to a roller with a foam attachment. To obtain a textured surface, fur attachments are ideal. If you want to make the wall as smooth as possible, then you need to use velor.

Separately, it is worth paying attention to the structural rollers . They are used to apply special paints to create a grainy effect on the surface.

Ceiling surface whitewashing technology

Let's start this section of the article with the fact that there is a strict prohibition. It is based on the postulate that it is possible to whitewash a ceiling with lime mortar only if it has been whitewashed with this particular material. The same applies to chalk whitewash. That is, you cannot apply chalk if the surface was previously covered with lime.

Chalk leaves marks on the palms Source wallscloud.net

How to determine what building material the ceiling was whitewashed with. To do this, you need to run it with a damp hand. The lime will not remain on the palm, and the chalk will cover its entire surface. But on a lime ceiling there will be wet stains, but not on a chalk ceiling.

If the ceiling is whitewashed for the first time, then this problem does not exist. Therefore, first we will consider the option of whitewashing on an unprepared surface. And then we’ll deal with whitewashing the ceiling using the old whitewash.

Whitewashing a plastered ceiling

In principle, this process is divided into two stages: preparation of the ceiling plane and direct application of the whitewash material.

At the first stage, the ceiling is simply leveled and brought to maximum smoothness. For this purpose, today they use putties, which are applied in one or maximum two layers. The latter is sanded, but not always, because the whitewash material hides minor surface defects. So you don't have to use sanding. The only thing that needs to be added is that the use of primers will change the adhesive properties of the ceiling surface. Therefore, both the plaster layer and the putty layer must be treated with a deep penetration priming liquid.

Attention! Whitewashing is applied after the applied layers have completely dried.

Primer of the ceiling surface Source stroychik.ru

So, let's move on directly to the process of applying whitewash. There are two effective ways. To do this, use either a paint roller or a spray gun. How to whitewash a ceiling with the first tool.

To do this, the roller is dipped in the prepared mixture, rolled over the tray and the ceiling is whitened using V-shaped movements. This is how you can achieve uniform painting. Some craftsmen carry out whitewashing like painting. That is, stripes are applied with a roller, parallel to each other with an overlap of 5 cm on each side. But in this case, you must adhere to one rule: apply stripes only perpendicular to the wall where the window is installed. If a two-layer application of whitewash material is used, then the first layer is applied parallel to the wall with the window, the second perpendicular.

Attention! The second layer of whitewash can be applied only if the first one has dried well.

In this process, a brush or small roller is necessarily used to clean hard-to-reach places. Previously, in general, they used wide brushes, brushes or brushes for whitewashing. But that's all in the past.

As for the spray gun, this is the fastest, most effective method that evenly distributes the whitewash material over the ceiling surface. Often one layer is enough to cover the ceiling completely.

Whitewashing over old whitewashing

So, let's move on to the next question - how to whitewash the ceiling using old whitewash.

In general, experienced craftsmen know that the best option, which will lead to a high quality of the final result, is a completely cleaned ceiling surface before the plaster or putty layer. And a new whitewash is already being carried out on it.

But if the task is to “refresh” the ceiling, that is, to carry out cosmetic repairs, then you can apply whitewash material over the old finish. The main thing here is that the ceiling plane meets certain quality standards. For example, there was no peeling of the old material, no cracks appeared on the ceiling, no dark spots, etc.

That is, if everything is in order, then the technology for applying the whitewash layer is no different from that described above. But if the quality of the ceiling leaves much to be desired, then you will have to get rid of the old finish. How to do it right.

Washing the ceiling

Since we are considering two types of materials used for whitewashing, namely, chalk and lime, we will accordingly consider two technologies - how to wash off whitewash from the ceiling.

Let's start with lime whitewash. For a very long time paste was used for this - a mixture of water and flour. It was simply applied to the ceiling surface and waited for the material to dry. After that, the applied layer was removed with an ordinary spatula, which also captured the lime whitewash, because the paste is, in principle, glue that is tightly bonded to the lime layer.

Today this option is not used, it is too complicated and time-consuming. Therefore, first they tap the ceiling with a hammer, and then try to remove the lime with a spatula.

Removing whitewash using paste Source potolok-exp.ru

Attention! Wetting the whitewash and then trying to remove it will not work. The lime will simply spread over the surface, decreasing in thickness.

But chalky whitewash is removed with warm water, to which ordinary vinegar is added. The ceiling is simply treated with a water-vinegar mixture and time is allowed (10-15 minutes) for the decorative layer to swell. And then remove the chalk with a spatula.

If the whitewash does not swell the first time, the ceiling is wetted again. It is better to rub problem areas with a sponge and let the area dry.

And one more thing - how to determine that the ceiling is ready for a new chalk whitewash. Just run your hand over it. There should be no traces of chalk left on it.

The video shows how to remove whitewash from the ceiling:

Features of whitewashing the ceiling with lime

To whitewash the ceiling with lime, you need to prepare a working solution; to do this, perform the following steps:

Take 2-3 kilograms of slaked lime and dilute it with a small amount of water, no more than 1 liter.
Add about 100 grams of soaked table salt or 200 grams of aluminum alum.
If necessary, a dye is added; in most cases, approximately 500 grams of ordinary blue is added to the lime mortar.
The mixture is thoroughly mixed and warm water is poured into it, bringing the volume to 10 liters.

Whitewashing the ceiling with lime mortar is done using a roller, a hard paint brush or a spray gun. The direction of the first layer should coincide with the direction of the flow of sunlight from the window opening. The second layer is applied in a perpendicular direction. This technology allows you to get a beautiful and even coating without traces of painting tools.

In the process of whitewashing the ceiling with lime mortar, certain rules should be followed:

Home craftsmen without experience in whitewashing ceilings with lime are recommended to use a roller or sprayer to achieve a better result. He also recommends that you read the recommendations of experienced painters on the question of which roller to whiten the ceiling with.
Paint brushes must be soaked in warm water.
The working area is well moistened before applying the lime mortar.
During operation, the temperature in the room should be monitored; it should be at approximately the same level. The same rule is followed during the drying period of the whitewashed surface.
Drying the painted ceiling should occur in natural conditions, without the use of heaters.

As for whitewashing the ceiling with a roller using chalk mortar, similar rules are followed.

How to whitewash a ceiling using old whitewash: 11 steps

You can whitewash the ceiling yourself, without the help of specialists. Among the huge variety and modern possibilities for decorating shelves, whitewashing still remains a relevant method of finishing it. Whitewashed ceilings are cheap and simple. In addition, sometimes you can refresh the ceiling without touching the previous finishing layer, then the question arises of how to whitewash the ceiling using old whitewash.

Benefits of lime whitewash

Lime is a material widely used in construction, which is produced by burning limestone or chalk rocks. According to its composition, lime can be slaked or quicklime. Slaked lime is formed by mixing lime powder with water and has the following beneficial qualities:

Antiseptic properties;
Resistance to temperature changes;
Moisture resistance;
Environmental Safety;
High wear resistance;
Can be applied to any building material;
Ability to tighten small cracks;
Low price.

Due to its bactericidal properties, lime whitewash is still used in educational and medical institutions for cladding ceilings and walls. Resistance to low temperatures makes this material indispensable for poorly heated and damp rooms, such as cottages, garages, basements, cellars and various outbuildings. In some cases, lime whitewash is even used for cladding facades.

Whitewashing the ceiling with lime is also appropriate in residential areas when it is necessary to minimize the cost of repairs.

Lime whitewash adheres well to a flat surface, gives the ceiling a light shade, and does not pollute the air with harmful fumes, since this material is of 100% natural origin.

How to find out what was applied to the ceiling before

There are two main ways to determine what kind of whitewash there was before:

External characteristics. If you run your hand over the surface, the chalk smears, but the lime does not. In the case where the ceiling was painted with water-based paint, the coating simply peels off, but leaves no traces;
We use lemon juice. Ordinary chemistry. Chalk will hiss under the influence of acid.

If you run your hand over the surface, the chalk smears, but the lime does not.

What to do with cracks

To achieve a beautiful, even color, you must level the surface. After removing the old layer, cracks or bumps often become noticeable. To eliminate this situation, it is best to use adhesive putty. It is quite easy to prepare. You need to take 1 liter of warm water and dilute 50 g of glue in it. A mixture of gypsum, wood glue and gypsum in a 1:2:2 ratio is added to the liquid. We wait until the putty is completely dry and carefully rub the entire canvas. After this, it should be primed.

To achieve a beautiful, even color, you must level the surface.

How to whitewash a ceiling with chalk

Before whitewashing the ceiling with chalk, you need to take care of preparing a working solution for whitewashing the ceiling. To do this, do the following:

Take about 5 liters of warm water.
Dissolve about 3 kg of chalk, 30 g of wood glue and about 20 g of regular blue in water. Blue in the chalk solution for whitewashing allows you to enhance the whiteness of the bleached ceiling. To obtain a bluish surface, you need to add more blue.
All components are thoroughly mixed.
Next, take a regular kitchen knife and lower the blade into the prepared mixture. Determine the required consistency: if the solution flows off the knife, then the addition of dry chalk is required. The procedure is repeated until a viscous mixture is obtained.

Having made the right decision about which roller is best to whiten the ceiling, having prepared the working solution and the necessary painting tools, you can begin directly painting the ceiling with chalk solution.

Coating the ceiling surface with chalk mortar using a whitewash roller is carried out several times, and each subsequent application is carried out only after the previous layer has completely dried.

The best results are obtained when using a paint roller or spray gun. In any case, before whitewashing the ceiling with a roller in the room, you should cover the furniture and floor with plastic film, old sheets or newspapers, thereby protecting them from splashes of the working solution.

In addition, you need to know how to properly whiten a ceiling with a roller. It is recommended to start the whitewashing process in the corners and junctions of the ceiling and walls. These difficult areas are coated with a paint brush. This approach allows you to avoid marking already finished and decorated walls.

Important nuances

When repairing the ceiling surface, you should take into account the purpose of the room. For example, if this is a bathroom, it requires the use of a special composition that is resistant to high humidity and can protect 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.

Preparatory work

First you need to cover all the furniture in the room. Floor carpet or other covering - remove and take out. You should also wear protective clothing. At the preparation stage, you need to wash off the previous whitewash with warm water. If there are rusty or dirty spots or stains on the surface, these also need to be thoroughly cleaned, then treat the surface with copper sulfate.

Preparing the whitewashed ceiling

If there are greasy stains, the surface should be treated with 2% soda ash and rinsed with water. Smoky areas (this applies to kitchen areas to a greater extent) are wiped with a 2-3% solution of hydrochloric acid.

Using a wooden block you need to smooth the plaster. Existing cracks must be carefully filled with putty, and then the ceiling surface must be primed. Upon completion of the preparatory work, you can proceed directly to whitewashing.

The process of whitewashing a stream with lime

Primer for better application

It is very important to prime the ceiling well before whitewashing. In this way, the applied material will adhere better to the old layer, minor irregularities will be hidden, and the service life will increase. The soil also has moisture-resistant properties and is bactericidal. The primer will make the surface less porous, which means that the amount of chalk, lime or paint solution will be significantly reduced. For processing it is better to use a strengthening mixture.

It is necessary to dilute the primer in accordance with the instructions, and then carefully and evenly apply it to the surface to be prepared. It is impossible for smudges or “bald patches” to remain. After waiting for complete drying, if possible, it is advisable to apply another layer.

The soil has moisture-resistant properties and is bactericidal.

Types of lime and methods of its preparation

To obtain a solution for whitewashing, lime is used, which can be quicklime or slaked. The first type of bulk material is calcium oxide, which is usually packaged in bags in the form of small lumps. To prepare a solution for whitewashing, quicklime must first be quenched. To do this, pour it into a metal container and gradually fill it with water in a 1:1 ratio, stirring constantly. By increasing the dosage of water, lime milk is obtained.

When preparing lime, the mixture must be thoroughly stirred

After completing the slaking process, the reservoir with the lime solution is set aside for a day, and then the contents are filtered through gauze. Since the combination of calcium oxide with water is accompanied by a violent reaction and the release of heat, all work should be carried out taking precautions and avoiding splashing of the solution.

It is much easier and safer to prepare lime whitewash using slaked lime. To obtain an amount of solution sufficient to treat a ceiling of 10 m2 in 2-3 layers, you must:

1.7 kg slaked lime;
40 g of blue, which gives the whitewash a bluish color.

First, the lime is diluted with a small amount of water to a homogeneous consistency, and then the solution is brought to the required volume and filtered. To impart water resistance and strength, about 50 g of table salt is added to the composition, previously dissolved in warm water, and 75-100 g of aluminum alum. Blue is also first diluted with a small amount of water, and then gradually introduced into the lime mortar until the desired shade is obtained.

Creating a color scheme

After the required type of material has been selected, you need to decide on the shade. You can choose the color you like, or you can create a shade yourself. Any color from a large palette of colors will help you create a color scheme.

Kohler – enamel with a rich color. With its help you can get unique shades.

This is especially beneficial when you want to paint in several shades, but there is no point in buying material of different colors.

Tinting is a very simple process, accessible to everyone, but you must follow the dosage. Before starting work, the color is mixed with water, then added to the base. Depending on the desired color intensity, different proportions of color and base are mixed. Ultimately, the amount of pigment should be from 1.5 to 20%, depending on the type of base.

Color bases have many advantages. Among them:

long service life;
resistance to fading and abrasion;
brightness;
quite budget price;
wide palette of colors.

For a successful combination of colors in the interior, you must remember three approaches to choosing a combination:

Monochromatic. Colors of the same tone, where the color scheme varies within one color.
Color harmony. When one color is selected and next to it a shade that combines with the main one.
Contrast. On the contrary, you can play on the contrast of colors, which will definitely make the interior bright and stylish.

Any combination of colors will look good in the room, depending on the style you choose.

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 solution has many advantages. It allows you not only to save time, but also to get excellent results. A professional will use a minimum amount of paint to whitewash the ceiling, so the repair will not cost much more than painting it 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 an inexpensive and simple way to transform the interior of a room for the better. 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.

Types of rollers

It is necessary to study the characteristics of the tools in advance, and then there will be fewer problems with the choice, because these products cannot be called universal. They are of the following types:

With foam rubber. An excellent option if varnishes and adhesives are applied. The only drawback is the ability to wear out quickly. It is better to use the tool when processing canvases.

When painting walls, it is recommended to avoid using such a roller. This device absorbs large amounts of paint, causing drops and smudges to appear on the surface.

Fur. They have good absorbency. Almost all the paint remains on the treated surface. As a result, we get a uniform layer, devoid of smudges and unpleasant changes. Can be combined with any colors. Flint from such rollers may remain on the base.

Velor. Also compatible with any type of paint. They contribute to the formation of smooth and beautiful layers that have no roughness. But this variety is capable of absorbing a large amount of material. Therefore, it is not always suitable for those who are interested in how to paint with a roller.

Thread or polyamide. Such rollers are made from fabrics stitched with special threads. An ideal option for covering walls with any variety of materials. These tools are convenient and easy to work with and will allow you to achieve the desired result. The main thing is to be careful to avoid splashing. Then it will be easy to figure out how to paint walls with a roller.

When choosing a tool, you must conduct a careful visual inspection. The presence of fibers and protruding threads on the surface is unacceptable. If you choose fur products, then the longer the pile, the better. An ideal solution for wallpaper with deep patterns or walls with uneven surfaces. A short pile is acceptable if you have to process walls where everything is smooth.

But it is not only the type of material that needs to be taken into account. An equally important factor is the width of the roller. 30 centimeters is the optimal parameter for use in city apartments. If the roller has an increased width, then difficulties arise during further work. It will require taking diluted paint in large quantities, and the process itself will become more complicated.

It is recommended to purchase not only the roller, but also additional components for it. For example, the process is made easier thanks to the extension handle. Or a special grater - it helps to get rid of residual material.

The use of paint rollers provides the following advantages:

Process large areas in a short time. The quality of the finished surface pleases customers for many years.
Compared to a brush, a roller is a more convenient and pleasant tool for constant use.
Long handle connection. This will allow you to stay on the floor while you work.

But the device also has some minor drawbacks. Those who are concerned about how to paint with a roller should also remember them.

Inconvenient processing of joints and corners. Then the brushes do a better job.
Some varieties absorb too much paint. In this case, a special spinning device will help.

Safety precautions

Safety precautions are critically important so that repairs do not harm your health. You will need a respirator, as there will be a lot of dust and after just an hour of working without protection, coughing attacks will begin. You should protect your eyes with construction glasses. They can be found in any hardware store, they are not expensive - 150-200 rubles (the price is valid for March 2021), and the eyes will be safe, because the whitewash solution is quite acidic and can greatly irritate the mucous membranes of the eyes. It is also worth wearing closed old clothes (which you don’t mind) or a special suit to protect your skin. You can't do without gloves.
