Many people put off doing it for years overhaul in a room whose ceiling was originally covered with chalk or lime mortar. After all, the process of removing it is quite labor-intensive and, as a rule, is accompanied by a huge amount of dust. However, you can significantly simplify and speed it up, while getting rid of excess dirt, simply by following the advice of professionals.
Preparatory work
Whitewash removal tools
- Preparing the premises. At this stage, it is important to remove all furniture from the room and, if possible, remove chandeliers, lampshades and sconces. The fact is that whitewash material easily settles on all types of surfaces, and then is very difficult to remove from them. In particular, we are talking about pieces of furniture that have a fabric covering.
If it is impossible to remove the furniture, you can use durable plastic film, oilcloth or paper, covering all surfaces with them and securing them with masking tape.
In addition, it will be necessary to take care of doorways, windows, and, if necessary, walls or floor covering. It is better to place a wet rag on the threshold of the room in which the chalk coating will be removed so as not to spread dust throughout the house. Windows, walls and floors can be covered with paper or film.
- Preparation of personal protective equipment. Dry methods for removing chalk or lime whitewash involve the appearance of a certain amount of dust that has an negative impact on the eyes and respiratory tract. They must be protected with special plastic glasses and a respirator or gauze bandage.
In turn, removing whitewash wet method leads to the formation of a weak alkaline solution, which can also get into the eyes or onto the skin, drying it out. Therefore in in this case you will have to prepare not only goggles and a respirator, but also work clothes, which will cover the body well, as well as gloves.
- Preparation of materials and tools. Their quantity directly depends on the method of removing the coating from the ceiling - dry or wet. In the first case, you will need a spatula, sanding paper to clean the surface, or a scraper with a collector attached to it, allowing you to collect the whitewash being removed. In the second - water, a spray bottle, a paint roller, a brush or a sponge. If necessary, you may also need an additional spatula or scraper.
The process of removing old chalk or lime coating is greatly simplified by special products and solutions that are sold in hardware stores.
The easiest ways to remove
The choice of the optimal method for removing whitewash from the ceiling depends, first of all, on total area the room in which the work will take place. If its square footage is small, the traditional dry method is quite suitable.
Dry
The spatula is the simplest and effective means in the fight against outdated whitewash
It requires the use of a wide metal spatula, thanks to which it will be possible to remove the whitewash from the ceiling layer by layer. In this case, any irregularities that arise can be smoothed out with sandpaper. The advantage of this method is its simplicity and the absence of the need to purchase additional funds removing old coating. But the disadvantages are labor-intensive, time-consuming and a huge amount of dust.
However, you can get rid of them:
- placing a special box on the spatula. It can be purchased at a hardware store along with the spatula or scraper itself, or you can make it yourself. The uniqueness of this device is that it allows you to avoid dust settling on all surfaces. You can replace it with any container.
- using a grinding machine. It allows you to speed up the whitewash removal process without losing quality and is ideal for large areas.
- gradually applying water with a spray bottle or a wet sponge to the layers of whitewash. Once they are soaked, they can be easily removed with a spatula, thus avoiding the appearance of a cloud of dust. In this case, you can replace the spatula with a scraper.
When choosing this method, you should not soak the entire ceiling area at once. It is much wiser to divide it into several sections and process them in turn. As a rule, the process of wetting the whitewash layer takes 5-10 minutes.
This method is best used in small rooms or in rooms with a small layer of whitewash to avoid the appearance of a large amount of dirt. Meanwhile, its occurrence can also be prevented by simply wiping the swollen layer of whitewash with a damp cloth.
- “tapping” evenly with an ordinary hammer on the old whitewash, especially if it is calcareous and thick. Peeling pieces can be easily removed with a spatula.
Wet
For many years, a wet sponge has remained one of the most popular tools for removing whitewash.
It is also considered one of the simplest and is a regular whitewash wash. In this case, it can be done with a wet, hard rag or brush. Its main advantage is high efficiency, but its disadvantage is labor intensity and the appearance of dirt. You can get rid of it by resorting to help washing vacuum cleaner. However, taking into account this advice, do not forget that it can negatively affect the condition of the household appliance itself.
Using special solutions
- 2 tbsp. grated laundry soap should be mixed with 5 tbsp. soda ash and dissolve in 10 l. warm water. The resulting solution must be applied to the ceiling with a sponge or roller and left until completely absorbed, and after swelling, remove with a spatula and scraper.
- Mix 2-3 caps of bath foam available in the house with 1 tbsp. l. acetic acid. Dilute the resulting mixture with 5 liters. warm water. The solution must also be applied to the ceiling and left for 10-15 minutes, and after swelling, removed with a spatula or a hard rag. It is ideal even for rooms with a large area, but in this case it is better to divide it into small areas (up to 5 sq.m.) and process it in order.
- Pour a 3% solution of vinegar or of hydrochloric acid(it's available at the pharmacy) soak the whitewash in a bucket of warm water and the resulting solution, then remove its remains with a spatula.
The choice of the optimal solution should be carried out taking into account the type of coating. For chalk, soap solutions are most often sufficient, while for lime it is better to use acidic solutions. Meanwhile, experts advise initially preparing a small amount of them and checking their effectiveness in each individual case.
Paste
Applying paste to whitewash is one of the oldest and effective ways its removal
This method involves preparing a paste - special staff from water (1 l.) and starch or wheat flour(2 tbsp) In this case, the latter is first dissolved in a small amount of water, and then mixed with the rest until a liquid jelly is formed.
Subsequently, it is applied evenly to the surface of the ceiling with a large soft rag or brush and left for some time to saturate the whitewash layer. The uniqueness of the paste is that after hardening it binds the entire coating layer, turning it into a solid crust that can be easily removed with a spatula.
Properly prepared and evenly applied paste to the ceiling does not leave behind any dust or dirt.
Removal using glue and newspapers
This is one of the easiest ways, which helps subsequently save time on cleaning the room. It involves gluing old newspapers to the ceiling with any inexpensive glue. In this case, one edge of the newspaper should remain intact so that you can pull it after the glue has completely dried. The uniqueness of this method is that it allows you to leave almost the entire layer of whitewash on the newspaper. Small remnants of coating on the ceiling can be easily washed off with warm water or simply removed with a spatula.
There are a number of industrial products that, after drying, change color and thereby signal that you can safely begin removing the coating.
An excellent alternative to the solutions described above self-cooking are special industrial products for removing whitewash, which you can buy at a hardware store. The principle of their action is similar to paste. They bind layers of chalk or lime coating in the same way, which, after drying, are removed with one movement of a spatula. Moreover, their uniqueness lies in the special structure of the solution, which is capable of changing color after complete drying, thereby signaling that you can begin to remove the whitewash. In addition, they are distinguished by convenient packaging, which ranges from 3-5 liters.
The use of such products is characterized by high efficiency with minimal labor costs and the absence of dust.
Checking the quality of work performed
The final stage of any method of removing whitewash from the ceiling is washing it. It is performed with clean warm water and a sponge. After the surface has dried, simply run your hand over it. The absence of traces of white on the skin is a guarantee High Quality executed works.

Methods for removing whitewash and the necessary tools
It is not always easy to achieve the desired result and quickly clean the surface using only one method of removing whitewash. In the course of performing such dirty work, many use completely different approaches, trying to find the most optimal option for yourself. Ensure freedom of use in various ways possible using standard set accessories for removing whitewash from the ceiling. You will need:
- spatula - it is necessary to quickly scrape off the whitewash;
- an ordinary paint roller, sponge or natural fabric, brush, hand spray;
- water – for spraying surfaces or washing sponges, rollers, brushes;
- soap, soda, bath foam, acetic acid (3 percent), whitewash remover, cheap wallpaper glue, which can be made from flour or starch and water.
Use a spray bottle to spray the ceiling
Attention: to avoid inhaling lime and damaging your eyesight, you must use a respirator and special glasses. Thus, lime dust and fine particles construction waste will not be able to get into the respiratory tract and eyes.
Important: be sure to buy plastic film, the area of which should be sufficient to cover the furniture and floor located in the room.
Advice: before starting renovation work, it is better to remove all pieces of furniture to the next room (to make it easier to move bulky structures, they should be disassembled). Such precautions are necessary because the film is not always able to completely protect objects located in the room being repaired and dust easily gets under the polyethylene.
Another item that doing without means harming yourself and the quality of the repair is a stepladder. You can, of course, use a high table or chair. But if you choose alternative option you will legitimately have problems transporting a heavy table or injury - after falling from a small and awkward one to repair kitchen utensils.
Working with a spatula
People who are interested in how to remove old whitewash from the ceiling very often look for the most simple options cleaning surfaces. The main thing they focus on is inexpensive ways removal of the old limestone layer, the use of which requires a minimum auxiliary material. These include the “dry” method of removing whitewash with a spatula. It is completely inexpensive from a financial point of view, but takes a lot of time.
It is usually quite difficult to pick out a dry layer of whitewash with a spatula. In addition, when performing such work, dust flying in all directions will seep into all sorts of places, even penetrate through locked doors into the next room. Conclusion: working with one spatula is long and unpleasant, and cleaning up after removing dry whitewash will be even more painful.
A spatula is a reliable friend in repairs
Attention: carry out repairs in work clothes.
Water to the rescue
If you are not attracted by the prospect of long cleaning, eliminating the consequences of dry removal of chalk or lime, try removing whitewash from the ceiling without dirt using water. Can be used clean water without any additions. You will need a paint roller or sponge and a container for liquid. Dip the roller in water and begin to wash off the old whitewash. This way you will protect yourself from flying dust.
When removing chalk whitewash with water, other unpleasant consequences may occur - the liquid will flow down the roller, pour into the sleeves, and drip onto the face and floor. To prevent this from happening, you can use a little trick - attach a large one near the handle of the roller plastic cover, having previously cut it to the middle (on one side), or make a hole in the center. As a result, water will collect not in your clothes and on the floor, but in the lid. If you don’t want to make things up, buy a roller with a casing.
Protects from annoying splashes
Attention: to wipe off whitewash with ordinary water, you need a little skill, a lot of patience and physical endurance.
Things will be a little more fun if you add detergent. A regular one will do. bubble bath. You can prepare a soap solution that is effective in removing whitewash yourself. It will require soap, baking soda and, of course, water. Make a solution in following proportions:
- 5 liters of water
- 1 tbsp. l. soap shavings
- 2.5 tbsp. l. soda
Please note: whitewash should be removed with foam and soapy water in the same way as with ordinary liquid.
Attention: to check the cleanliness of the ceiling, you should pay attention to the water with which you wash the whitened surface. If after dipping the roller into the liquid it remains transparent, the ceiling is clean.
Tandem of water and scraper
Now we will tell you how to quickly remove whitewash from the ceiling using water and a spatula. To remove the coating you will need:
- Spray
Note: using water and a spatula correctly to remove whitewash, you will not encounter as much dust as with dry removal.
So, pour water into the sprayer. You can use the one that is usually used to moisten the leaves of houseplants. Irrigate with water small area ceiling.
Wait a few minutes and before starting to remove the whitewash with a spatula, spray the adjacent area with water. This strategy will save time, because after the whitewash is removed from the first piece of the ceiling, you can immediately proceed to the second, without waiting until the coating is saturated with liquid.
Let's share a trick: to prevent whitewash scraping off with a spatula from polluting the room, you should use a modernized scraper equipped with a small container.
Attention: if, while cleaning the whitewash, the chalk solution flows down the spatula, this means that you have overdone it with water. Solution: wait a little and let the surface dry. And vice versa - flying dust during whitewash removal indicates an insufficient amount of water splashed on the ceiling.
A ceiling spatula will help with plain water
Acid and wallpaper glue
We present two more methods for removing whitewash, distinguished by their originality. Perhaps some of them will appeal to you more than the previous options. To implement the first method, you need to stock up on the same scraper, and also purchase acetic acid (we will need 3 percent). Treat the ceiling thoroughly with acid. After this, the whitewash will swell and you can easily clean it with a spatula.
The second method is even more extravagant compared to the first, since the whitewash is removed using wallpaper glue (regular or homemade). We spread an adhesive store-bought or homemade starch (or flour and water mixed) substance onto the ceiling. We wait until it is covered with a crust, after which we clean everything off with a spatula.
Interesting: some products designed to remove whitewash act in a similar way. Many of them can be mixed with glue to improve the effect.
The next option for removing whitewash using an adhesive mass does not require the use of a spatula. You will have to use newspaper to remove glue and whitewash. To do this, a newspaper is attached to the industrial/homemade paste spread across the ceiling, one of the corners of which should protrude. After 5 minutes, when everything has dried a little, you need to grab the edge of the newspaper and sharply tear it off. Whitewash should remain on the paper. This method of removing whitewash is quite difficult, but it also has its advantage - the absence of old coating on the floor that has been cleared from the ceiling. The entire layer of lime will remain on the newspapers, which can be easily rolled up and thrown away. Cleaning up won't take much time, except you may have to wipe off a few drops of glue.
Flour paste - replacement store product
Grinding
For people who are interested in how to remove whitewash from the ceiling quickly and easily, we can suggest doing this using a grinding machine. This option is suitable for those who are not afraid of dust; it also involves the complete removal of furniture from the room where they are being held. renovation work. At the same time, when treating the ceiling with a large abrasive, it is necessary to wear safety glasses and a respirator. It turns out that the advantages of this method are the speed of removing the chalk layer, the disadvantages are great education dust, which means serious and tedious cleaning, and the high cost of a sanding machine. If you don't have one electrical device, but you don’t want to buy it, then try to borrow the device from your friends.
This is what it looks like quick removal whitewash
Attention: grinding machine can be replaced with a grater and sandpaper, but you need to understand that manual removal of whitewash is a more difficult process that brings a lower quality result.
The choice is yours
Each of the proposed methods has its pros and cons. Your task is to choose the most optimal one from the options. Let us remind you that when carrying out whitewash removal work, it is imperative to use personal protective equipment (respirator and goggles). Before you attempt any repairs yourself, reconsider hiring professionals who will save you time and effort.

Specialization: facade finishing, interior decoration, construction of cottages, garages. Experience of an amateur gardener and gardener. We also have experience in repairing cars and motorcycles. Hobbies: playing the guitar and many other things that I don’t have time for :)
The process of removing whitewash from the ceiling is generally quite simple. However, due to the fact that the field of activity is located above the head, and even at a decent height, home craftsmen often encounter some difficulties. Therefore, in this article I decided to tell you how to wash off old whitewash from the ceiling quickly and without much effort.
When to wash off whitewash
Before moving on to the description of the process of removing the old coating itself, I will say a few words about in what cases this operation is required. The fact is that many finishing options can be completed without removing the chalk or lime layer.
So, delete this coating necessary in the following cases:
- if mold appears on the surface;
- before painting with water-based paint;
- before facing with polystyrene foam boards, which are glued.
When installing suspended and tensile structures The old one, of course, can be left alone. In addition, it is allowed to whitewash the ceiling using the old whitewash.
The only thing is that before you whitewash the ceiling using the old whitewash, you need to remove the dirt. To do this, wipe the surface with a damp sponge or rag. Besides, keep in mind that the composition must be of the same type, i.e. Lime whitewash cannot be applied over chalk whitewash.
It is very easy to determine what kind of whitewash the ceiling is covered with; to do this, you need to spray the surface with water. If the drops are absorbed, it means it is whitewashed with chalk; if the drops remain on the surface, it is whitewashed with lime.
Surface preparation
Regardless of how exactly the chalk will be washed off, Before you begin this procedure, you need to prepare:
- since washing is a dirty job, furniture and other items must be removed from the premises;
- if you cannot take out some items, they must be covered with film;
- It is imperative to prepare special clothing - a hat, safety glasses, etc. If cleaning is carried out using a dry method, you will additionally need a respirator or at least a gauze bandage to protect the respiratory system;
- You should also prepare a stepladder or a high table from which you can reach the ceiling, and you will also need a certain set of tools, which I will tell you about below.
After preparation, you can proceed directly to work.
Whitewash removal options
There are quite a few options for cleaning whitewash from a ceiling. The most effective and widespread are the following:
Method 1: water
First of all, I will tell you how to quickly remove whitewash from the ceiling with water, since this method is perhaps the simplest and, as a result, the most widespread. To work you will need the following set of tools:
- sprayer or paint roller, preferably with a special tray;
- cotton rag;
- putty knife.
Instructions for doing this work look like this:
- Before removing the old coating, it must be moistened. To do this, spray water or wet the ceiling with a paint roller. Water should be applied sparingly so that it does not drip from the ceiling;
- after 10 minutes, wet the ceiling again;
- Now you need to remove the whitewash from the moistened ceiling using a spatula. The coating should fall off in layers. If the whitewash flows down the spatula, you should wait a little until the surface dries;
- after removing the chalk with a spatula, you need to wash the ceiling with your own hands with a cotton rag or sponge soaked in warm water;
- After the ceiling has dried, run your finger over it. If there is chalk on your finger, wash the ceiling again.
Cracks that appear on the ceiling during the washing process should be widened with a spatula. This way you will immediately prepare the ceiling for repairs.
The disadvantage of this method is a large number of mud. Therefore, before you wash the ceiling, be sure to cover the floor with film.
It must be said that in some cases, if the coating is applied to the ceiling thin layer, it can be washed off immediately with a wet cloth without cleaning it with a spatula. True, in this case the process will be even dirtier.
Method 2: newspapers with paste
Now I will tell you how to remove whitewash without dirt. To do this you will need old newspapers and paste or even cheap wallpaper paste.
The process of removing old coating using this method looks like this:
- Before removing the whitewash, you need to prepare a paste. To do this, dilute the flour in a small amount of water, then place the pan with clean water to the fire. When the water boils, gradually pour the flour solution into it and stir.
After obtaining the consistency of the dough, the pan must be removed from the heat and then cool the resulting composition; - after that, take old newspapers, treat them with paste and glue them to the ceiling. Leave the corners of the newspapers untreated so that they can be easily torn off;
- now wait until the paste dries and tear off the newspapers with a sharp movement, pulling them by the corners;
- After this, you can wash off the remaining glue and whitewash with a regular mop and rag.
This procedure is carried out using the same scheme using wallpaper glue. The most important thing is to wait until the paste or glue is completely dry..
Method 3: with a special wash
Currently you can buy in construction stores special remedy for removing whitewash. Cleaning the ceiling with it is quite simple:
- first of all, the composition must be sprayed onto the ceiling;
- further, before removing the whitewash, you need to wait until it turns into a crust, which easily lags behind the base;
- Now you need to clean the surface with any suitable tool, for example, a spatula. It must be said that dust is not formed during such cleaning, but dirt cannot be avoided.
Method 4: homemade wash
If you haven’t found a whitewash remover on sale, don’t worry. Next, we’ll look at how to quickly clean the ceiling with a homemade remover.
To do this you need to follow these steps:
- fill a clean container with five liters of water;
- add a tablespoon of vinegar and a few caps of any bath foam to the water;
- Treat a section of the ceiling with an area of no more than three to four square meters with the resulting composition;
- Before cleaning the ceiling, wait until the coating has softened. This usually takes about five minutes;
- after this, the surface must be cleaned with a spatula;
- At the end of the work, the ceiling should be washed warm water. As in previous cases, before washing the surface, cover the floor with film.
It must be said that when choosing what to wash off whitewash with, you can also give preference table salt. The latter should be dissolved in warm water in a ratio of 1:10.
The price of a homemade remover is significantly lower than the cost of purchased compounds, and the effectiveness is in no way inferior to them.
Method 5: scraper with container
How to wash off whitewash with water and by various means we figured it out. Now I will finally tell you how to remove the coating using a dry method. For this you will need special device– a scraper with a container suspended from it.
You can make such a device yourself from a small spatula and a plastic bath. Small holes should be drilled in the spatula so that you can hang the bath on it using wire.
As a result, you will be able to scrape off the whitewash with a spatula, and it will go straight into the container. The disadvantage of this method is the large amount of dust that is generated during the cleaning process. Therefore, as mentioned above, before starting work, respiratory tract protection should be ensured.
Conclusion
Each of the above methods for removing whitewash is quite effective, but at the same time contains its own disadvantages. Therefore, you should choose individually, depending on the conditions and the availability of certain funds at your fingertips.
You can get more information from the video in this article. If you encounter any difficulties during the process of cleaning the ceiling, ask questions in the comments and I will be happy to help you.
Whitewashing the ceiling a few years ago was a very common finishing option, but now it has almost completely given way to new, better and more durable technologies (painting, wallpapering, decorative plaster and so on.).
Important! In order for the new coating to have sufficient adhesion and not begin to fall off in good faith after a couple of months, it is necessary to completely get rid of the previous whitewash. This will ensure good “adhesion” of the applied materials.
It's no secret that the whitewash layer after drying looks like a dense chalk surface, which, under abrasive load, begins to generate a lot of dust. The consequence of this is the possibility of severe contamination of the room. This dust is very finely dispersed and tends to get deep into cracks, furniture fabrics and any other interior elements.
The question is removed if we are talking about a complete overhaul of the room, but often you just need to update the coating, and finding a solution to how to remove whitewash from the ceiling without dirt becomes very important.
So, the task at hand can be outlined in several points:
- Minimum dirt
- Simplicity of the process
- Minimum costs and unnecessary movements
To solve any problem, you only need to have some skills (if you don’t have them, they are acquired quickly enough in the process) and a set of tools. In our case, the final goal is clear, now let's move on to the tools. You will need:
Additional accessories include masking film (tarpaulin) and tape, a knife, as well as some personal protective equipment - a respirator, safety glasses and gloves. It is especially worth taking care of the safety of your eyes, because during this work you will have to constantly look up, and some materials (like lime) can contain a strong alkaline component, which corrodes the mucous membrane of the eye, and the skin of the hands too. In addition to gloves, it wouldn’t hurt to apply some kind of protective cream (with added silicone or glycerin) to your hands.
Means of protection
Armed necessary set, you can begin the process of removing the whitewash from the ceiling. Preparatory stage(again, in case of partial or cosmetic repairs) there will be careful “packing” of the remaining furniture in the room using a plastic awning and masking tape.
The more tightly the furniture is closed, the less later you will have to spend effort to remove clogged dust.
The same can be said for walls, floors and window and door sashes.
Sprayer is filling hot water, and then the part of the whitened surface is evenly moistened. To quickly remove whitewash from the ceiling, the amount of water applied must be necessary and sufficient. As a rule, spraying is carried out in two stages with short time intervals. If, after running a spatula across the ceiling, part of the old coating remains, it means there is not enough moisture. If the whitewash turns into a kind of liquid putty and smears, this indicates that there is too much water. A layer properly treated with water will be removed with a scraper like softened paint, completely falling behind the ceiling surface.
Remember that it is faster to replenish the lack of moisture than to wait for the excess to dry out.
It is easy to determine exactly which area needs to be moistened directly during cleaning - the coating should not have time to dry. While one area is freed from whitewash, the second must be moistened to soften it. In order not to contaminate the floor during the removal process, a spatula is held in one hand, and a tray in the other, into which the removed whitewash falls.
It is possible that periodically you will come across areas in which, along with the whitewash, the old plaster. In this case, it is possible to simultaneously prepare the ceiling for sealing seams, cracks and irregularities.
If chalk whitewash If applied in a not too large layer, it is very convenient to use a special scraper for washing windows instead of a spatula. The role of the coating-removing plate here will be played by dense rubber, and the mesh with foam rubber on the other side will serve for the final washing of the chalk. In this case, the ceiling should be moistened quite abundantly. This method can be seen in the video:
Another option for removing old whitewash from the ceiling is to use inexpensive wallpaper glue and newspapers. The paper is glued to the ceiling, but not completely, but so that one corner remains unsticked (as on plastic packages with cottage cheese, for example). After a certain period of time, the newspaper comes off, and the whitewash comes off with it. With this method, the amount of dust and debris is practically reduced to zero.
When the question of repair arises, especially in “USSR” buildings, it becomes necessary to remove all former finishing coatings.
These include, of course, old whitewash. It can be on the ceiling and on the walls. The following article will help you get rid of it correctly and completely.
Preliminary preparation
There are several methods for removing the entire layer of whitewash from the ceiling surface. However, despite each option, adequate preliminary preparation is required. The following steps should be taken.
Preparatory activities:
1. There are many methods for removing a layer of whitewash from a surface ceiling material, but, in any case, you will need to ensure proper personal protection and familiarize yourself with basic current knowledge.
2. Try to remove any movable materials and structures away from the door. Electronics, furniture, Appliances, curtains, carpets and other decorative and functional elements must certainly be moved to another, separate room.
3. Any movable furniture located in the room must be removed (removed) directly behind doorway. Probably with carpets small furniture, there will be no technical difficulties. If things are large, then you need to carefully and generously cover them with polyethylene. The film should be carefully secured with tape around the perimeter, scrupulously gluing all seams and tears.4. Then you need to cover the floor surface with a protective film. As a replacement - film or special paper.
5. Lamps or a chandelier from the ceiling will need to be temporarily disassembled. For work safety, you will have to turn off the apartment electricity, then all the plaster can be removed without fear.
Attention! It is necessary to ensure that the apartment is completely de-energized, since the wiring from neighboring rooms can carry electricity. Especially in dorms or communal apartments!
6. Lime coating is not entirely safe material for everyone's health. It can irritate mucous membranes, eyes, wound surfaces and skin.
It is necessary to be completely protected from splashes and lime dust when working:
— respirator and plastic mask;
— adsorption suit;
— gloves made of thickened rubber;
- an additional medical cap to prevent lime from dripping.
Methods for removing whitewash
Let’s move on to a detailed consideration of the most effective, accessible and acceptable methods of “fighting” surfaces treated with lime.
Classic way
The most classic and outdated, but still common method of removing the whitewash layer is the use of a conventional metal spatula. Of course, this process is very lengthy and technically difficult to implement, but the result is fully consistent with the labor and time costs. This technology is recommended for use in indoors, characterized by a very thick layer of lime on the ceiling.

It is better to do this work with the following tools:
- rags or large sponge;
- a brush with stiff, short bristles;
- warm water and spray bottle;
- a set of different-sized spatulas with sharp metal blades.
The working method is as follows:
1. Heated water is drawn into the spray bottle, which is sprayed over a small area through the outlet nozzle. ceiling area. When there is no sprayer, you will have to manually draw water into a bucket, wet a sponge (rag) and intensively rub the ceiling surface.
Recommendation! In order for the old lime to be thoroughly saturated with water, you need to wait 13–19 minutes. If the thickness of the whitewash is large, then wetting must be repeated at least several times (2-3)!
2. Take a wide-plane sharp metal spatula and begin the process of prying off the old coating layer and removing it. Completely soaked lime will be easily and completely removed from the main surface. If necessary, hard-to-treat areas should be additionally moistened.
3. After passing with a wide spatula, the surface is soaked and cleaned with finer plane tools.
Thus, the entire required area is cleared of the whitewash layer in stages.
4. When the entire surface is free of lime, additional cleaning must be done. Grains and particles of the substance will still remain on the ceiling. You can bring the ceiling surface to excellent condition by finishing cleaning, which is done as follows:
— with a moistened hard brush, remove the remaining whitewash and clean out seams, recesses, cracks, etc.;
- Use a damp cloth or sponge to completely wash off the remaining material.
Application of grinding machine
Using modern apparatus– a grinding machine, removing the coating is quick and much easier, for example, in comparison with the “spatula” method. Of course, there is a significant drawback - the formation and spread of a considerable amount of fine dust.
Advice! It is better to use a grinding machine when carrying out general overhauls, when the room is completely empty, and debris accumulates from other manipulations!
Using the technique under consideration, you will need the following tools and materials:
- respiratory protection, respirator;
- directly herself Sander;
— special clothing that reliably covers the employee;
— durable safety glasses for construction and installation work;
- a suitable bedspread.
First, you need to reliably protect the working person (or yourself) - dress in appropriate clothing and use protective equipment.
