How to whitewash the ceiling on the old whitewash? How to whitewash a ceiling - simple options for transforming a snow-white surface Whitewash falls off

During the renovation, we are faced with various types finishes, one of which is whitewashing the ceiling. If the repair is not carried out in a new home, but in a previously finished one, it often becomes necessary to remove old finishing materials.

The ceiling is no exception. At final finishing, depending on the material possibilities, the purpose of the room and whitewashing with the following compositions can be used: water-based paint, chalk, lime mortar.

Content:

Many people are interested in how to whitewash the ceiling using old whitewash, since the removal of chalk whitewash does not require serious material costs, but it causes domestic inconvenience.

Is it possible to whitewash the ceiling with old whitewash?

We will immediately stipulate: to carry out any Finishing work, except as a wireframe, without removing the chalk, it is highly undesirable. This is due to the fact that the whitewash prevents the new material from adhering to the base, which can lead to delamination, swelling and other undesirable consequences. But if there is no other way out, consider the best way to whitewash the ceiling and how best to do it.

First of all, we will find out in which cases it is impossible to whitewash the ceiling without washing off the whitewash:

1. The presence of unsealed cracks.
2. The presence of stains, especially rusty, or untreated fungus.
3. Multiple previous whitewash.
4. Not tight adhesion to the base of the old layer.

If you are dealing with this state of affairs, it is better. However, there are cases in which it is possible to either leave it completely or carry out a partial repair:

1. The thickness of the old layer is minimal, or not significant.
2. There is no shedding of whitewash and other delaminations.
3. The ceiling does not need additional repairs.

In these cases, it is enough to either simply treat the surface with an acrylic primer deep penetration or carry out local repairs, primer and you can start whitewashing the ceiling.

Before you start finishing work, you must perform the following steps:

1. Depending on your situation, either remove the old whitewash or make the necessary local repairs. Of particular danger are stains, protruding rebar and various mold cultures.
2. Using chalk or gypsum putty, remove minor defects, and if necessary, completely process the ceiling.
3. Fully prime it with an acrylic primer.
4. Wait for it to dry and start painting.

Whitewashing the ceiling with water-based paint roller

For painting, you can use either or a simple paint brush. If we are talking about whitewashing on a whitewashed ceiling, it is necessary to take into account its type, for example, it is impossible to cover the chalk coating with a water-based composition, the ceiling must be removed to the base, but it is enough to prime lime and old latex coatings with an acrylic primer. Followed by:

• Pour the water-based composition into a cuvette.
• Dip the roller into the ditch, and, evenly distributing the paint over the fur coat, blot the excess paint.
• Whitewashing of the first layer of paint is carried out depending on the parameters of the ceiling in such a way that the second layer is, if possible, along it.
• Wait for the time specified by the paint manufacturer.
• After that, you can whiten the second layer.
• Proceed to whitewashing the ceiling sections at the joints with the walls.

If you are going to whitewash the ceiling, please note: the lowest consumption will be when using a spray gun, but this method requires special professional skills and special equipment. In addition, the paint should be free of lumps and more liquid, so its hiding power is reduced. Of the positive aspects, one can note the uniformity of painting and the absence of stripes.

How to whitewash a ceiling with chalk

First of all, for this you need to prepare a chalk solution and strain it thoroughly. The usual proportion is prepared: for 10 liters of water, 5 kg of chalk and 50 g of wood glue, you can add a little blue.

The technology of whitewashing the ceiling with chalk does not differ from applying a water-based composition, apply the chalk composition in an even layer, wait until it dries completely and repeat the process. In the case of applying it to the ceiling with a paint sprayer, applying a second layer can be avoided by the duration of the whitewash, but be sure to achieve uniform coverage.

Such a coating will have a pleasant matte structure, it is much cheaper, but it also has its drawbacks, over time, the chalky coating can crumble, it is not resistant to wear and high humidity.

How to whitewash a ceiling with lime

Lime mortar has sufficient moisture resistance, in addition, it can hide small defects in the ceiling, strengthen cracks and crevices. Also, lime has antibacterial properties, which makes it suitable for work in rooms with high dampness.

A significant disadvantage lime mortar is the ability to cause allergies. And the drying time is slower compared to the chalk composition.

Whitewashing the ceiling with lime is done in the same way as chalk, however, more stringent safety measures will be required, due to the characteristics of the lime mortar itself, it can cause allergies, and it is more dangerous for the eyes.

Thus, we considered several options for whitewashing the ceiling with water-based paint, lime, and chalk. Which one to choose is up to you, but still remember that if you have the opportunity to remove the old whitewash, it is better to do it.

A huge variety of finishing materials is replacing the old methods of repair, and lime whitewashing is no longer as widely used as it was 50 years ago. But this generation-tested method is fully consistent with the expression "cheap and cheerful." If you are planning to whitewash your walls, ceilings, or borders in your garden, look into the properties slaked lime how to prepare it correctly, calculate the consumption of the solution and apply it to various surfaces.

Lime is not the easiest material to use. However, it occupies its niche in the building materials market quite firmly and is very reluctant to lose ground. Given all the advantages and disadvantages, in certain cases the use of lime whitewash is appropriate, and sometimes it is more appropriate to choose another method.

Budget finishing material

Important properties of lime whitewash

Lime, known to everyone from school, is called calcium oxide in chemistry textbooks. For whitewashing, slaked lime is used, that is, it has reacted with water. In chemical language, slaked lime is a strong base - alkali. It has good disinfecting properties, because the aggressive alkaline environment adversely affects the fungus, pests and other unwanted animals.

Lime whitewash is not afraid humid air does not crack or blister. In addition to resistance to high humidity, walls treated with this substance are resistant to temperature extremes.

Fluff powder

For whitewashing, it is not necessary to wash off the existing coating, it can be applied to the old finish. Moreover, if a network of small cracks has formed on the surface of the walls or ceiling, treatment with a solution of slaked lime will strengthen the finish and extend its service life.

The cost of lime for whitewashing in stores cannot be compared with the price of other finishing materials. This is due to the fact that the production process is very simple - it is an elementary firing of lime rocks in a kiln. Raw materials cost a penny, so the price of the product is low. A thirty-kilogram bag costs about $2.

Where and why it is advisable to use lime

The properties of antiseptic and fungicide make slaked lime a leader among finishing materials for damp and cold rooms: cellar, shed, garage, basement and the like. It is used for walls and ceilings. The weather resistance of the substance allows it to be used for whitewashing facades.

The record holders for the use of lime for whitewashing and other tasks are summer residents. Here it is in full swing. It is customary to whitewash walls both inside and out, add quicklime to the soil to change its acid-base balance, treat tree trunks to protect against insects and animals, curbs for beauty.

Trees are bleached from pests

In those rooms where practicality, not aesthetics, comes to the fore, and the financial side of the issue also matters, lime mortar is also used to cover walls and ceilings. This can be observed in the entrances, on landings, in common corridors, foyer.

It is quite appropriate to whitewash the ceiling in this way in any living space. Schools, hospitals and other institutions still use lime mortar for wall decoration. After drying, calcium hydroxide becomes safe, does not emit any harmful substances.

Buying lime - what to take and how much

Before going to the store, you need to find out which lime to buy for whitewashing - slaked or quicklime, how much it is required and what other components will be needed. This will save you from having to go to the construction market again, if suddenly the solution is not enough or its properties do not meet your requirements.

How to make slaked lime with your own hands

As you already understood, slaked and quicklime is absolutely different substances, which are united only by a consonant name and the presence of calcium in the composition. For household repair work slaked lime is used. It is sold by weight at any hardware store or farming department.

Kipelka - lumpy lime

However, it is not uncommon for a household to have a fairly large supply of quicklime and it is desirable to use it rather than buy slaked lime. In this case, it can be extinguished independently, especially since this chemical process does not require the skills to conduct such experiments in the laboratory.

So, how to prepare lime for whitewashing from lumpy quicklime "boiler". First you need to take care of personal protection. Since you will be dealing with a rather aggressive alkali, take care to protect your eyes (glasses), respiratory organs (respirator), exposed skin (closed clothing and gloves). This must be done in the air.

Video: How to prepare a whitewash solution

You will need a deep container, such as a bucket and a stirring tool - traditionally a stick. The list of ingredients is also short:

• lumpy quicklime;
• water.

Quenching process

The water must be cold, this is the only condition. Even a first-grader will remember the proportion - 1: 1.

Step-by-step instruction:

1. For 1 kg of calcium oxide, take 1 liter of cold water.
2. Combine all this in a container and mix. Almost instantly, you can observe the beginning of a powerful chemical reaction with the release of a large amount of heat. When quenching, the mixture sometimes heats up to 150 degrees, it is not for nothing that the people called the substance a boiling water - the solution literally boils.
3. When the reaction stops, heat and gas cease to be released, lime can be considered "fluff", that is, slaked. However, it is not yet suitable for whitewashing.
4. The solution should ripen within 2-3 weeks under a lid in a dark, cool place.

Solution proportions and consumption per square

To start whitewashing with lime with your own hands, you need to prepare at least the following set of materials:

• powdered fluff or lime paste;
• water.

Fluff packing

In addition, all kinds of auxiliary substances are often added to whitewash, which give it certain properties. The stock solution is prepared in a ratio of 1:3. For every kilogram of fluff, take 3 liters of water. As a result, 4 liters of solution can be prepared from 1 kg of the substance.

Lime consumption per 1 m 2 during whitewashing directly depends on the type of surface on which it is applied:

• The largest consumption is about 1 liter ready solution per square, will leave when whitewashing raw brickwork.
• A flat prepared surface suggests approximately 0.5 liters per square meter of area.

Room preparation

Another criterion that affects the cost is painting tool. More often they use an ordinary flat brush or a round one - a maklovitsa. These tools are wasteful, the mass is applied in a thick layer, streaks and drops can form. The spray gun can significantly reduce material consumption and operating time. Often, instead of a spray gun, a reverse blower vacuum cleaner and even hand-held tree sprayers are fitted.

How to calculate the amount of fluff and water

Before you dilute slaked lime for whitewashing, you need to perform some calculations. An example cost calculation is as follows.

First you need to calculate the area of ​​\u200b\u200bthe walls and ceiling that you plan to whitewash. For example: room 3 by 5 m, ceiling height 2.5 m. It was decided to process the ceiling and part of the walls from the middle of the height to the ceiling with lime whitewash.

Wall area: (3 * 2.5 + 5 * 2.5 + 3 * 2.5 + 5 * 2.5) / 2 = 20 m 2.

Ceiling area: 3 * 5 \u003d 15 m 2.

total area: 35 m2.

A solution of the desired consistency

Based on the average consumption of 1 liter of solution per 2 m 2 of surface, it is easy to calculate required amount for whitewashing - 17.5 liters of lime mortar. You can round up to 18, and preferably up to 20, because the average consumption is a rather flexible concept.

That is, 20 liters of solution are required, and this is 5 kg of slaked lime in powder. It is worth noting that the finished lime dough, which is sold in hardware stores, is diluted in the same proportion, which means that the calculation is correct for it.

Whitewash leaves traces

Additives to improve durability and combat imperfections

Since lime has been used in construction for a very long time, there are many " folk recipes and methods that improve the properties of this substance. Still, modern water-based paints appeared not so long ago, and craftsmen were forced to study chemistry right at their dacha or at home.

The first problem that is solved by adding a secret ingredient to a solution of lime whitewash is grinding. A dried surface tends to stain everything and everyone who touches it. What to add to lime so that it does not smear? This ingredient is in every home - table salt. It has a good bonding effect. Add 100 g of salt per liter of solution.

Salt - so that it does not smear

Another problem, especially when using whitewash for outdoor use, is the rapid washing off of the composition with water. It has long been known what to add to lime so that it does not wash off - a fatty component is introduced into it - drying oil. Drying oil repels water and allows whitewash to last longer. Proportion 1:10, 100 ml per liter of solution.

Practice adding laundry soap, grated on a coarse grater, PVA glue, wallpaper glue, acrylic primer. All this is done in order to ensure maximum adhesion of the whitewash to the wall, to exclude its swelling and bubbling.

Drying oil - not to be washed off

White is not the only possible

To prevent the lime coating from becoming yellowish, ordinary blue is added to it - methylene blue. It will take 10-20 g per liter. The whitewashed ceiling will become snow-white. But sometimes it becomes necessary to get a lime mortar of other colors. You can’t call this mass whitewash, and not every dye is suitable. Use only those pigments that are resistant to an alkaline environment - mineral, but in no case organic.

Pigments that are used for lime paints:

• ocher (yellow shade);
• umber (greenish brown);
• minium (orange);
• mummy (red-brown);
• chromium oxide (green);
• titanium dioxide (white);
• lithopon (white);
• ultramarine (blue).

Pigments are used to make

To prepare lime paints good quality, it is not recommended to add the pigment in its pure form - powder. It is pre-diluted with water until a paste is obtained. Then the pigment paste is allowed to infuse for about 24 hours. And only after that the dye can be added to the solution. This is due to the fact that pigment grains often do not dissolve well and can drag on the brush, forming ugly color streaks.

How to apply the composition to the surface in accordance with all the rules

Instructions on how to whitewash walls with lime look very diverse. The thing is that each master has his own recipe for a lime mixture, his own tool, which means his own technique. But you can try to combine the fundamental points into one algorithm. It will turn out a universal method, which everyone has the right to supplement or slightly correct depending on the situation.

A roller is suitable for the ceiling

Is surface preparation necessary?

If the task is to quickly whitewash the walls and the decorative side of the issue does not really bother you, you can skip the preparation stage altogether. In fact, you can whiten directly on top of other coatings without worrying that the result will not live up to expectations. But if the walls are covered with adhesive paint, then you need to remove it first.

If speed is not your priority, then it is best to prepare the surface for the application of lime mortar. So the result will be more accurate. The old whitewash is washed off, swollen places on the plaster are removed, sanded, puttied. The same applies to cracks, if any.

Preparing the ceiling for whitewashing

Plain water is used as a primer. The surface is lightly wetted for better contact. And if the mixture contains one or more of the additives listed above, then adhesion will be even better.

It is important to protect all other surfaces from accidental contact with lime. All furniture, if it cannot be taken out of the room, the floors and walls are hung plastic wrap. The worker must wear a protective suit, gloves, goggles and a mask for personal protection.

A few secrets of uniform application

The application process is not particularly difficult. A brush or maklovitsu is dipped into a container with whitewash, the solution is applied to the walls or ceiling with a thin layer. For the ceiling, it is better to use a tool with a long handle. It can be made by hand. This will make it easier to work and eliminate the need to climb on unstable structures from tables and chairs.

Direction of brush or roller movement

Whitewash is applied in several layers - 2-3. Each layer must be applied perpendicular to the previous one. So the coating will be more uniform, there will be no streaks and thickening. There are often gaps in the corners. In these places it is better to walk with a brush again.

Between the application of layers it is necessary to withstand the time interval. The previous layer must dry completely. This will happen much faster if the layers are made thin. The thinnest and most uniform layer will be obtained using an electric spray gun. The lime mixture is poured into the tank and sprayed onto the surface in tiny drops. This eliminates the appearance of divorces.

Airbrush - the solution to many problems

Despite the fact that the process of whitewashing walls and ceilings with lime is not a big deal, for someone who has encountered this for the first time, it may seem like an impossible task. Especially when it comes to a high ceiling or an extensive amount of work on large areas. It is never too late to turn to the master - a professional in his field. He can easily do this work efficiently and much faster than a beginner.

We all have to do from time to time redecorating your dwelling. And despite the abundance of finishing materials on the shelves construction stores, the usual whitewashing of walls and ceilings is still very popular. Although such a coating is short-lived, you can resort to it at least every year.

Even a novice master can whitewash ceilings and walls with his own hands. Requirements for materials and tools are minimal. Let's try to evaluate the clear advantages of such a process:

1. Cheapness. If it's time to make repairs, and you are limited in funds, whitewashing is the best solution.
2. Simplicity. Even an unprepared person can easily cope with the work.
3. Accuracy. Although the whitewashed walls are clearly inferior to modern decorative pasting - the same Venetian plaster, with a competent approach, it is possible to obtain the original matte surface. In addition, dye can be added to the white, which will clearly benefit the design of the room.
4. Environmental friendliness. The applied finish easily passes moisture, allows the walls to "breathe", which cannot be said about tightly glued wallpaper or tiles.
5. Active protection. Lime whitewash is not susceptible to fungus or mold, as it is able to resist bacteria.

As for the shortcomings, the following should be highlighted:

• fragility - after a couple of years, it is advisable to repeat the repair;
• uncomplicated look;
• When finished, there will be a big cleanup.

In this video, the expert will share unusual idea for painting the walls in the apartment.

Tool selection

Can be used simple tools, such as a brush or roller, as well as "advanced" equipment - an airbrush and a household vacuum cleaner equipped with an airflow blowing option.

1. A roller and brush are suitable for a small front of work - whitewashing a garage or a small apartment.
2. The roller is more convenient as a way of whitewashing high ceilings if you equip it with a homemade long handle.
3. Mechanical devices - a vacuum cleaner and a spray gun - are used when processing serious areas: entrances, external walls, street fences.

It is better to choose a special brush with natural bristles. The desired width of the tool is 15-20 cm. If you carefully wash the bristles at the end of the work, it will last a long time.

The roller is convenient when whitewashing is done in one layer. By applying a second layer, you can remove the dried first one. But it is with its help that it is possible to give the surface a matte finish.

The sprayer allows you to quickly apply the composition in a thick layer, easily masking existing small defects. Please note that with such work, the consumption of the solution increases greatly.

The vacuum cleaner with "blowing" is equipped with a special polyethylene cover with a tube that allows the device to be used as a sprayer.

Instructions for whitewashing

For those of our readers who are interested in how to whitewash the walls, we present detailed instructions. Let's start with preparation:

1. Since whitewashing is a “dirty” job, it is advisable to either take everything in the room to another room or cover it with a protective film.
2. The old whitewash is cleaned with a wash. To do this, the walls are moistened with warm soapy water using a sponge. Wet whitewash is easily removed with a spatula. We recommend that you remove the pieces and immediately put them in a special container so as not to stain the floors. At the end, the residue is washed off.
3. The cleaned surface is prepared. Rust is washed, then disinfected blue vitriol(70-100 g per liter of boiling water). Grease spots cleaned with 2% composition soda ash- dip a rag into it and apply it to the stain until the fat is removed. Get rid of soot by blurring the composition of hydrochloric acid (2-3%).
4. The surface is covered with an antifungal mixture.
5. Explicit defects - cracks and pits - close up with putty or plaster. Let dry, then smooth with sandpaper.
6. Apply a primer, wait a day until it dries.

Everything, now you can start whitewashing. The building material can be slaked lime (fluff, etc.), chalk, water-based paint. Let's get to know them in more detail, and at the same time we will tell you how to dissolve the whitewash for the walls.

Lime

Due to its low cost, it is the most demanded material. Usually, quicklime is "quenched" with water.

Advantages of lime coating:

1. It fits well and quickly on any walls: brick, wood, concrete and plaster.
2. It is characterized by bactericidal qualities. It is recommended for kindergartens, schools and clinics. As an antiseptic, it is used to treat walls in cellars and sheds, poultry houses.
3. Properly applied coating can last 3 years or more.
4. Not afraid of moisture, suitable for rooms with high humidity- bathrooms, kitchens, baths, etc.
5. It absorbs well into small cracks.

You also need to be aware of the disadvantages:

1. When working with lime, be sure to follow safety rules. The main condition is to work with gloves to protect your hands from burns.
2. The material leaves stains and streaks.
3. Dangerous for people suffering from allergic reactions.

Lime mortar must be prepared. For cooking you will need:

• 10 liters of water;
• 2-3 kg of slaked lime;
• 150-200 g of aluminum alum;
• 50-100 g coarse salt, pre-soaked;
• 1 tsp blue for whitewash or 0.5 kg of dye to give the walls a certain color.

The composition for colored whitewashing must be made in an amount that is enough for the entire production area, otherwise it will be difficult to achieve a similar shade. Consumption is estimated at the rate of 0.5 liters of composition per square meter. m.

Quicklime can be extinguished at home by mixing with water in the same proportion. The composition must be mixed for 20 minutes, then stored in a closed container for 15 days.

When applying whitewash, follow a simple rule: the first layer is applied perpendicular to the window, the second - parallel to the frames. This approach avoids streaks. It is advisable to lightly moisten the surface to be treated with water.

Chalk

This material is also often used, since chalk is cheap, and in terms of environmental friendliness it is not inferior to lime. In addition, it is much safer to work with him. In addition, chalk whitewash:

• has a more saturated white color than calcareous;
• does not cause an allergic reaction.

True, there are also disadvantages:

• chalk absorbs moisture, so this product is not suitable for bathrooms - the walls quickly crack and peel off;
• if applied incorrectly, spots and bubbles form;
• against the wall is easy to get dirty.

The chalk composition is prepared according to the recipe. Norm for a plot of 10 square meters. m:

• 5 liters of warm water;
• 30 g of wood glue;
• 3 kg of sifted chalk;
• 15-20 g blue.

All ingredients are carefully dissolved in water. The consistency of the composition is checked by dipping a knife blade into it. Properly prepared composition should be slightly sticky to the blade. If necessary, add chalk in small portions, mixing and re-checking the consistency.

Application rules:

• perform in several layers, at least two;
• after applying one layer, allow time to dry completely;
• it is impossible for the walls to dry in drafts or under the influence of sunlight;
• each subsequent layer is applied perpendicular to the previous one.

Water based paint

It would be more correct to call such processing not whitewashing, but painting, although the paint is made on the basis of cement and lime. Mineral water-based paint:

• resistant to abrasion and temperature changes;
• has bactericidal properties;
• allows the walls to "breathe";
• safe for people;
• dries quickly.

True, the material costs more than the previous ones, but the coverage is not enough for a short time.

It is recommended to whitewash or paint ceilings only after the old finish has been removed. However, the matter is rather complicated. Cleaning old chalk or lime from the ceiling is long and tiring. In addition, there is a lot of dirt left in the house after that. Previously, glue was added to the chalk solution before whitewashing. If the surface is finished with just such a tool, cleaning it completely turns into torment. Therefore, for sure, many owners of houses and apartments would like to know if it is possible to whitewash the ceiling using old whitewash, and how to properly perform such an operation.

What you need to know

In principle, it is possible to paint or whitewash ceilings without removing the old coating. But not in all cases. So, for example, it is highly undesirable for old whitewashing with chalk if it is covered with lime (and vice versa, respectively). Otherwise, sloppy stains will definitely appear on the ceiling. If you don’t want to clean off the old coating, the ceiling should be whitewashed with the tool that was used before. You should also not use lime or chalk if the surface was previously treated with water-based paint. The surface simply does not gap. The ceiling will remain yellow no matter how many layers are applied.

Using paint - is it possible?

Many owners of houses and apartments are wondering, among other things, whether it is possible to whitewash the ceiling on old whitewash with a water-based emulsion. It is believed that the use of this tool is acceptable. But only if the layer old finish not too thick and holds on the ceiling quite firmly. oil paint or enamel on whitewash should not be applied in any case. When using them, the old coating will still have to be removed.

Finishing preparation

In the event that you decide to perform such an operation as whitewashing the ceiling using old whitewash, you will have to carefully prepare old surface. Chalk on a layer of plaster usually lies flat. Lime can also come off in chunks. Therefore, in the latter case, before whitewashing, you need to check the entire ceiling for the presence of such delaminations. Of course, all loose pieces should be removed with a spatula. After performing this operation, irregularities will, of course, remain on the ceiling. They need to be sealed with a special chalk putty or a thick lime mortar with the addition of a small amount of PVA glue (depending on the type of old finish). Of course, you need to lubricate all the cracks and chips on the surface.

Before proceeding with it, it is advisable to go over it with a damp cloth in order to remove dust, cobwebs, etc. It often happens that the old chalk or lime coating has yellow. After application new finish, this yellowness, most likely, will still shine through. Therefore, before starting work, such a discolored surface should be bleached. Such a need, for example, will necessarily arise when finishing the kitchen. Yellow ceilings there are also cases when one of the owners smokes right in the apartment. It is easy to whiten such a surface. It is enough just to add to the water in which the rag is dipped during cleaning, a little inexpensive Whiteness product. If the ceilings are very yellow, they should be passed with a roller soaked in the prepared solution. Next, you should wait until the surface dries.

Whitewashing the ceiling on the old whitewash: technology

Chalk and lime usually do not adhere very well to concrete. Therefore, the ceiling, previously finished with such a tool, should be processed using not a roller, but a spray gun. In this case, the surface will be smooth and neat. A roller is also allowed. But when using this tool during the work, you will have to carefully monitor that there are no stains on the surface. Of course, it is necessary to whitewash ceilings over old lime or chalk layers not in one, but at least in two or three layers.

Using a water emulsion

Having wondered about the old whitewash, one should, of course, decide, among other things, on the type of finish used. Chalk and lime are rarely used today in the design of floorings. In most cases, the owners of apartments and houses use water-based paint. This tool is applied to the surface of the ceiling much more evenly. In addition, the water emulsion does not exfoliate over time. But of course, such a finish will last a long time only if it is applied correctly.

Before painting, the bleached ceiling should be primed. In this case, you should use special remedy deep penetration. After the primer dries, you need to test the old coating for strength. To do this, just try to scratch the ceiling with a spatula. If the old coating is easily removed, it is better not to risk it and still remove it. If the chalk or lime impregnated with a primer hold tight, you can start painting.

Sometimes the owners of apartments and houses finish whitewashed ceilings with a water-based emulsion and without prior priming. This is also allowed. But only if very high quality paint from a good manufacturer is used.

Basic rules for whitewashing

Of course, before starting such an operation as whitewashing the ceiling with old whitewash, the room needs to be prepared. Floors and furniture should be covered with technical polyethylene film. Should be put on hands rubber gloves. This is especially important if it is used for processing. As you know, it can severely corrode the skin.

All doors and windows must be closed before whitewashing the ceilings with water-based emulsion, lime or chalk. Otherwise, ugly stains and stripes will appear on the ceiling after drying.

Application of special tools

The sprinkler gives a very thin layer finishes. Therefore, whitewashing the ceiling on old whitewash with water-based paint when using this tool should be done in at least three layers. This allows you to get a flat, completely white and clean surface. Before applying each subsequent layer, be sure to wait until the previous one is completely dry. This rule, by the way, is observed both when using an airbrush and a roller.

Is it worth it to finish the surface without pre-cleaning?

So, we found out whether it is possible to whitewash the ceiling on the old whitewash. In principle, this is allowed. Subject to all the recommendations listed above, the owner of an apartment or house can eventually get a fairly even and beautiful coating. However, to correct such a finish in the future, unfortunately, it will be necessary earlier than if the ceiling had been previously cleaned.

Therefore, before deciding to whitewash without removing the old layer, you should think carefully. Lime is held on the ceiling quite firmly. Therefore, if the surface is finished with it, applying a new layer without removing the old ones still makes some sense. But the chalk is removed from the ceiling very easily - just with a rag and water. Therefore, in this case, it is more advisable to pre-clean the surface.

There are various repair materials and facing the ceiling. From modern options it is necessary to take into account the weighted and stresses of the structure. Most often you use white washing or dyeing.

These decorative techniques are themselves recognized economically, quickly and easily in practice. The surface that is raised gives comfort to the room. You can freshen up ceilings with the help of experts. But when they found out how much a master costs, many apartment owners prefer to be red. How to do this, the article will tell.

Before you dig the bathroom ceiling yourself, you must prepare it.

The quality of work depends on this. If you do everything right and to the point, white wash will be homogeneous, without divorce, there will be no rust or grease through it. The smallest mistake can lead to the fact that everything needs to be done again.

How to prepare the white area for washing:

• removal of the old coating layer;
• Removal of traces of dirt, greasy yellow spots;
• leveling the ceiling.

Remove the old white wash with a sponge soaked in soapy water, paste or wide spatula.

Preparing the ceiling for painting

Before you paint the ceiling with a snowball, you should prepare its surface for this process.

Whitewashing the ceiling on the old whitewash

We note right away that it is impossible to apply paint on a layer of lime, so the entire coating should be removed from the ceiling. In order to do this quickly, you should follow a certain technology.

We take out all the furniture from the room and cover the floor with polyethylene.

Using a spray bottle, apply warm water to the ceiling. To make the process go faster, divide the ceiling surface into 6 zones. Spray the first part abundantly with water, and after 20 minutes repeat the process on the first part, and also grab the second.

After another 20 minutes, you can irrigate the second zone again, and the third, initially. While the wetted areas are sour, we begin to remove lime from the first area. According to this scheme, we clean the entire ceiling.

The remaining areas are washed off with a sponge and water.

Now our ceiling appeared before us in its original form.

We give the surface to dry, and apply a primer on it, of the same brand as the “snowball”.

The next step is to putty the surface of the ceiling with the starting mixture.

It is applied with a spatula in a thin layer.

After the putty has dried, we rub the surface of the medium sandpaper and again we apply a layer of putty, only the finishing one. When it dries, we polish the ceiling with fine sandpaper.

The final stage of preparatory work before painting is a primer.

We paint the ceiling with snow

Ceiling painting is not complex process and if the preparatory work is done correctly, then the result should be a high-quality ceiling canvas.

But before you paint the ceiling with a snowball, you should dilute it with water to the desired consistency. The ceiling should be painted in three layers. The first is superimposed along the width of the room, the second along its length. The last layer should be painted from window to door, this will make it possible to cover all the flaws, and will not highlight gaps. After each painting, the ceiling area must dry. Do not paint over a surface that is not yet dry, otherwise the coating may cling to the roller and fall off.

Tips to follow

Observe the temperature at which you can paint.

Paint should only be applied after the primer has dried.

Painting is done in three layers.

When painting the ceiling canvas with a roller, keep a brush nearby to paint hard-to-reach areas.

Having started painting one layer, work should not be interrupted.

It is necessary to finish painting to the end, otherwise the paint on the dried areas and the applied wet layer will stand out.

The ceiling should dry in natural conditions, without heating and drafts.
