How to remove old lime from the ceiling. How to remove whitewash from the ceiling and walls? Removal methods, recommendations from specialists. A good helper is old newspapers
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 or 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 the surface of a ceiling material, but, in any case, you will need to ensure proper personal protection and become familiar with basic current knowledge.
2. Try to remove any movable materials and structures away from the door. Electronics, furniture, household 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 moved (removed) directly outside the doorway. Surely there will be no difficulties with carpets, small furniture, or appliances. 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 wiring from neighboring rooms can carry electricity. Especially in dorms or communal apartments!
6. Lime coating is not a completely 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 enclosed spaces with 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 hard, 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 through a nozzle outlet over a small 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 a modern device - 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;
— the grinding machine itself;
— protective 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.
Important! A gauze bandage or a medical mask is an unreliable way to protect against dust particles and all kinds of tiny fragments!
The technology for carrying out the work is as follows:
The process of performing the work itself will be subjected to a step-by-step analysis:Repair of walls and ceilings begins with the removal of old coatings, for example, by washing off the whitewash. This procedure is simple, but dirty. The question of how to clean whitewash from the ceiling and walls quickly and without unnecessary labor costs is quite natural. Let's look at the most famous and effective removal methods.
How to clean walls and ceilings from old whitewash?
Anyone who has had to do it at least once in their life knows that before finishing work it is necessary to carry out rough work.
They are the ones who often take a lot of effort and time. For example, removing faded wallpaper or linoleum glued tightly to the floor.
But the most difficult thing is washing off the whitewash. To understand how to remove it from the walls, you need to familiarize yourself with some recommendations.
Why wash off the whitewash from the walls?
If you plan to renovate in accordance with the latest fashion trends and using the latest materials, then most likely you will not have to remove the whitewash (for example, when installing a stretch ceiling). But there are other cases that require careful rough work.
You cannot do without washing off the old whitewash in the following cases:
- before painting or gluing wallpaper, since the lime layer reduces the quality of adhesion of these materials to the surface;
- before new whitewashing using a composition different from the old one (adhesion to the previously applied solution may be short-lived);
- before installing a heat or sound insulating coating;
- (using putty, plaster) or eliminating cracks;
- when rust, mold or soot stains occur that are difficult to cover up and it is better to remove them completely to prevent their appearance in the future.
It is also necessary to get rid of mold if you plan to install a stretch or suspended ceiling, because it can easily spread to other areas of the surface. In addition, after removing the old whitewash, the surface should be treated with special agents that prevent the appearance of mold.
In other, unmentioned cases, it will be enough to simply remove the exfoliated whitewash with a sanding machine and remove the dust with a brush.
How to clean lime whitewash from walls and ceilings yourself
There are two traditional ways to remove old whitewash: dry and wet, although each of these options is further divided into some subtypes.
With the first method everything is extremely simple - the whitewash is removed using a sharp spatula. However, having decided to organize the work in this way, you need to prepare for the fact that upon completion of the procedure you will have to do general cleaning, because in the process of removing whitewash a huge amount of dirt and dust is formed.
A simple and practical way to remove the whitewash layer is with a wet wash. It has a number of advantages - it creates less dirt compared to the dry method and is easy to perform. It should be noted that there are several options for wet washing and all of them will be discussed in the text below.
How to wash off quickly without dust
Before you start washing off the old whitewash, you need to prepare your workspace. For this purpose, all furniture and interior items should be removed from the room or covered with plastic wrap.
A washing vacuum cleaner will allow you to remove the whitewash layer without dust. He will cope with this task as quickly and efficiently as possible. To do this, you need to connect a tank with a special solution to it and carry out a regular wash. The procedure should be repeated until the walls are completely clean.
When deciding to remove the whitewash layer with a washing vacuum cleaner, it is necessary to take into account that in the future the device will no longer be able to perform its functions. Therefore, for these purposes it is better to use an old vacuum cleaner that you don’t mind throwing away.
The above method is appropriate only when the number of whitewash layers is no more than two. Otherwise, using a washing vacuum cleaner will be a waste of time.
Is it possible to wash it completely with water?
You can also remove the whitewash layer using regular warm water. To do this, you need to wet the roller or sponge and treat the surface. After 5-10 minutes the layer will become wet and can be removed with a spatula. If you start working an hour after wetting the walls, you won’t be able to remove the whitewash with the same ease, since the surface will be completely dry by then. Taking this into account, experts advise treating the walls gradually, section by section, so that you do not have to do the same work twice.
Whitewash removers that will help remove limescale
Washing solutions will help remove whitewash from walls and ceilings: they can be purchased at any hardware store or prepared at home from household products that every housewife usually has on hand.
How to clean
Removing old whitewash with a homemade solution is an effective way that will save time and money on purchasing a store-bought product. So, let's look at the most popular and proven recipes:
- Soap-alkaline solution. To prepare it, dissolve 1 tbsp in 5 liters of warm water. l. crushed laundry soap and 3 tbsp. l. soda ash. Then moisten the whitewash with this composition, and when the layer swells, remove it with a spatula.
- A solution of 10 liters of water, 2 tbsp. has a similar principle of operation. l. vinegar and 5 caps of bathing foam
- The method using paste is no less effective. To make it, pour 6 tbsp. l. flour or starch 250 ml cold water. Mix thoroughly and pour a liter of boiled water into the prepared mass. Wait until the paste cools down, then apply it to the walls. When the solution dries, remove it with a spatula along with the whitewash.
List of popular means
If you don’t want to make homemade solutions, buy a ready-made product. Fortunately, such compositions are sold in almost every building materials store. Popular options are:
- “Probel” is a cleaning concentrate for dissolving gypsum dust and chalk layers. Does not leave behind streaks or whiteness. Used for cleaning surfaces manually and by machine.
- "Metylan" and "Quelyd Dissoucol" - used to remove chalk and plaster whitewash, as well as old wallpaper. Available in convenient containers of 0.25 and 0.5 liters. Diluted with water in a ratio of 1:10.
- "Alfa-20" - copes with chalky and more moisture-resistant lime whitewash. Often used when cleaning after renovation.
Many products are made on the basis of glue and are applied to the surface with a brush. After drying, the solutions are easily removed along with the whitewash. For these purposes, a regular spatula is used.
The advantages of these solutions are ease of preparation (just read the instructions) and speed of action. The main disadvantage is the toxicity of most products and their high price tag (especially if you compare them with self-prepared mixtures).
How long does it take to clean before wallpapering?
When getting ready, keep in mind that rough surface preparation work will take 2-3 days, depending on the scale of the rooms. This time includes removing old whitewash, sealing cracks (if any), applying and drying a primer.
Final whitewash cleaning
The final stage for each whitewash removal method is washing the working surface. You can cope with this task with a sponge and a bowl of warm water. After the walls are dry, run your hand over them. If the skin remains clean after this, it means the job was done efficiently.
Safety regulations
People working indoors must be kept safe, so be prepared with:
- respirator;
- latex gloves;
- protective glasses;
- special clothes, headdress.
All methods for removing whitewash are simple and at the same time effective. Home-made folk remedies will save you from unnecessary expenses, and purchased formulations are presented as concentrates, so one package is enough for a large area of the surface to be treated.
Useful video
No matter how hard you try, no one will be able to completely avoid contamination when washing off whitewash, so we’ll just try to reduce it to a minimum.
To do this, if possible, remove all the furniture from the room, and send carpets and household appliances there as well. It is allowed to leave bulky objects that do not block the surface of the ceiling, but they will have to be covered completely and without gaps with plastic film. It is best to seal the joints with tape to ensure safety, so that careless movement does not cause damage to the furniture.
It would be good to cover the floor with paper or oilcloth, optimally overlapping and in several layers.
The chandelier and other lighting fixtures will also have to be removed. Before you begin removing limescale from the ceiling, turn off the electricity, and, if possible, completely remove the wires from the surface to be washed off.
You need to protect not only the room, but also yourself from the harmful effects of lime - this chemical compound can dry out and burn the skin, mucous membranes, and hair. It is necessary to work with rubber gloves. Cover your hair with a hat or thick scarf, and clothing should cover the maximum area of your body. Use a respirator or, at worst, a gauze bandage, and protect your eyes with plastic construction glasses.
When choosing clothes for traditional methods of removing whitewash from the ceiling, keep in mind that they will become unusable in the future - the white stains will not come out.
How to quickly remove whitewash from the ceiling: spatula
The oldest and to this day the most popular way to remove a layer of lime from the ceiling is to remove it mechanically, with a spatula. The process is very labor-intensive, however, it is quite effective and, in addition, is well suited for rooms where the layer of whitewash on the ceiling is approaching record levels.
We will need:
- the actual spatula, or better yet several;
- a bucket of warm water;
- hard brush;
- spray;
- large rag or sponge.
A small area of the ceiling should be wetted with warm water and given time (10-15 minutes) to soak. This is easy to do with a spray bottle, but a sponge will also work. Inspect the surface - if the whitewash layer is impressive, repeat the procedure several times. It is necessary that all the lime is saturated with water - this is the only way it will yield to the spatula.
As soon as the whitewash swells and softens, use a spatula to pry up the entire layer of finishing and scrape it off. This should be done with the entire surface of the ceiling.
We wash away the remaining lime with a stiff brush and remove it with a damp sponge.
The fastest way to remove whitewash: a sander
This process is much less labor-intensive and time-consuming than the previous one, but it has one serious drawback: a lot of dust. If you are planning a major renovation of the room, and there is no furniture left in the room, the ideal option is to use a grinding machine (not a Karcher type washing machine, but specifically for cleaning).
In this case, a respirator is required (the gauze bandage will clog in a few seconds). Safety glasses that fit as closely as possible to your face will also come in handy.
When removing layers of whitewash with a sanding machine, be sure to wear construction glasses and a respirator, and only after that begin removing the lime layer. It would be a good idea to cover the doorway with a damp blanket from the corridor side - this will prevent dust from seeping through the cracks.
After such a procedure, extensive cleaning will be required, since no matter how careful you are, the dust will quickly spread throughout the house, and other types of finishing - neither paint, nor putty, nor wallpaper - will not adhere well to the dust.
How to quickly clean whitewash: do-it-yourself solutions for removing lime
Whitewash, which has often been tested, will not yield to simple warm water. In the kitchen, where lime has absorbed greasy steam for years, or in the bathroom, where it has been exposed to soap fumes, solutions will help soften the thick layer of the substance. They can be prepared from products available in every home, and their work efficiency will increase significantly.
For these purposes, an acid and soap solution or paste is used.
Soap solution to wash off whitewash
You need to prepare in advance:
- a bucket of warm water;
- half a piece of household soap;
- five tablespoons of soda;
- sponge or fluffy brush.
We grate the soap using a regular kitchen grater.
Attention! For the sake of convenience, you can use liquid soap or washing powder instead, but experts say that it is more effective with laundry soap.
Dissolve soap shavings and baking soda in a bucket of water, then use them to impregnate the lime layer. The whitewash should gradually melt from repeated application, but you can speed it up with a spatula.
Paste in the fight against whitewash on the ceiling
This is a very clean option for removing whitewash from the ceiling. It does not form streaks that are difficult to wash off and does not create huge amounts of dust. The main thing is to prepare a solution of good consistency, and it’s done.
We will need:
- hot water;
- wheat flour (or potato starch);
- brush with thick soft bristles;
- putty knife.
Calculate the required amount of ingredients: the consistency of the paste should not be very thick and not very liquid. One liter of the prepared solution will require two tablespoons of flour (starch).
The water needs to be brought to a boil, then pour a small amount of boiling water into a separate container and stir until smooth with starch or flour. After this, pour out the remaining water and stir thoroughly. You should get a runny jelly.
The easiest way to apply paste to the wall is with a large soft brush, because it must be done extremely evenly. The final result depends on how smoothly the whitewash layer is saturated with the solution. When the paste sets and hardens, it binds the entire layer of lime into a continuous crust, which can be easily removed with a spatula.
Acidic solutions wash whitewash
If all of the above methods do not seem effective enough to you, you can use the next option. It is worth mentioning that the method is practically safe; it uses very weak solutions, so you don’t have to worry about your health if you follow the precautions described above.
We will need:
- concentrated acetic or hydrochloric acid (sold in pharmacies);
- water;
- brush;
- putty knife.
We adjust the solution so that the share of acid is 3% of the total mass.
Important! Water is first poured into the container, and only then acid is added to avoid evaporation.
Lime is a type of alkali, and, as everyone remembers from chemistry lessons, it is neutralized by acid. Our weak solutions will not remove whitewash completely, but will destroy its dense structure. The whitewash, saturated with an acid solution, will begin to bubble, after which it can be easily removed with a spatula.
After washing off the whitewash, it is better to rinse the surfaces again with clean water.
Industrial solutions for cleaning whitewash
If you don’t have the time or desire to create the solutions described, you can use chemical industry products. They operate on the principle of a paste, that is, they bind all layers of lime so that after drying they can be removed with one movement of a spatula. Additional convenience is provided by the special structure of the solution, which makes it possible to remove the glued whitewash by changing the color.
You can buy them at construction stores. Packaging is usually convenient in the scale of use - 3-5 liters. Products from the companies Speed Stripper, Space, Kelid Dissukol, etc. are popular today.

The easiest way to remove limescale
A method that is accessible to everyone, easy to implement and cheap is to remove lime from the ceiling or walls using a simple construction spatula. This is the very first method of removing whitewash. So, to remove old whitewash using a spatula, you will need the following tools and materials:
- putty knife;
- container with warm water;
- brush;
- large sponge (can be used for washing cars).
When removing whitewash using a sander, you must wear safety glasses and a respirator.
Or walls with a spatula is a rather labor-intensive process. First, you need to provide yourself with reliable support; if the whitewashed area is high, place a table. Then take a spatula in your hands and, at an angle, pressing it with force, scrape off the easily amenable whitewash. If the lime has never been removed before, and several layers of it have already accumulated, then you need to take a container with warm water and, with a fluffy paint brush, soak all the walls and ceiling with lime. It is easy to spray the water using a spray bottle, if available. After a few minutes, when the water is sufficiently absorbed and does not drip or flow, apply a second layer and allow time to absorb well. After this procedure, the remaining lime can be completely removed with a spatula without much effort.
Before whitewashing the walls or ceiling again, you need to rinse the spatula with warm water using a voluminous sponge. This will help remove all the lime without leaving any residue and make it easier to remove this layer during the next renovation.

Preparing solutions for removing lime with your own hands
In some cases, to remove whitewash from surfaces, one spatula and warm water are not enough. We have to resort to more sophisticated methods, including preparing special solutions with our own hands from improvised means. These are the most common and convenient methods, so it is useful to know how to remove old whitewash using a soap solution, acids or paste. To prepare a soap solution you will need:
- 10 liters of warm water;
- a third of a piece of laundry soap;
- 5 large spoons of baking soda;
- mixing container;
- roller, sponge or brush.
You can remove old whitewash using a roller moistened with water.
Dissolve baking soda and grated soap in a container with warm water, stirring until smooth. For convenience, solid soap can be replaced with liquid soap or washing powder instead. Then apply the solution to the whitewashed walls or ceiling using a roller or brush. With each new movement it will be noticeable how the lime leaves the surfaces. Do this until the old whitewash is completely removed.
No less often, in order to remove old whitewash, a paste is prepared at home. To use this method, you need to prepare:
- hot water;
- starch or flour;
- mixing container;
- brush;
- putty knife.
Before preparing a paste for removing whitewash, you need to calculate its required volume depending on the area of application. Taking into account the fact that for 1 liter of paste you will need approximately 2 large spoons of a binder - flour or starch, prepare the proportions of the ingredients. To make the paste without lumps, the water for the solution must be boiling. To knead, pour a little water into the container and sprinkle in the required amount of flour or starch, stir thoroughly, then add the remaining amount of water. The paste is ready. The most convenient way to apply the paste to the walls is with a fluffy brush; this should be done as evenly as possible so that all layers of whitewash are well saturated. After which you should wait some time for the surfaces to dry, resulting in the formation of a dense crust of glued lime. Then easily remove the crust with a regular spatula. This method is the most optimal because it requires little effort, is economical and does not cause pollution.
Even if this method does not help, then it is useful to learn how to remove whitewash from walls or ceilings using acid solutions. This method is not very dangerous as it might seem, since only low concentration solutions will be used, which will not even leave burns on the skin. To prepare an acid solution that can easily remove old whitewash from walls or ceilings, you need to prepare:
- acetic or hydrochloric acid (can be purchased at a pharmacy);
- water;
- mixing container;
- brush or roller;
- putty knife.
To easily remove old lime, you will need a 3% solution of any of the listed acids. You can purchase it ready-made or prepare it yourself after calculating the proportion of the required amount of all ingredients. When preparing it yourself, it is important to remember that you first need to pour water into the container, and only then add the acid. Apply the resulting solution to the walls or ceiling with a brush or roller, as a result of which the lime will begin to swell, and we can easily remove its remains with a metal spatula.
It is also better to finish treating surfaces with any solution with a warm water solution applied with a sponge or roller.
Sooner or later, any room has to be renovated. To begin work, you need to decide on materials, color schemes and furnishings. Many people still prefer to use an option such as lime whitewash to cover various surfaces. As a rule, it lasts for a long time. But how to remove old whitewash from the ceiling quickly and without much effort? This is what will be discussed in this review.
Preparatory stage
What is he? The final result will depend on the quality of the preparatory work. Before removing the whitewash, all furniture must be removed from the room. If possible, it is also recommended to remove chandeliers, sconces and shades. The problem is that whitewash settles on all types of surfaces, and it is very difficult to wipe it off, especially when it comes to furniture with fabric coverings. What to do if you can’t take it out of the room? In this case, it is recommended to use plastic film, paper or oilcloth. These materials must be covered with surfaces. The coating is fixed using masking tape.
How to remove whitewash from the ceiling? Before you begin directly removing the whitewash, you need to take care of the windows and doorways. Consider also protecting your walls and flooring. You should place a wet rag on the threshold of the room in which you are going to remove the whitewash. This will prevent dust from spreading throughout the house. You can also use plastic film or paper to protect walls and floors.
Protective means
Many people are interested in what is the best way to remove whitewash from the ceiling? But no matter what method you choose, this procedure in any case involves the appearance of chalk dust. It can have a negative effect on the respiratory tract and mucous membranes of the eyes. Therefore, work should only be carried out using a respirator and special glasses.
If you choose to remove whitewash using a wet method, you should definitely consider using work clothes and gloves. The fact is that as a result of the work, a weak alkaline solution is formed, which, if it comes into contact with the skin or eyes, can cause irritation.
Materials and tools
What do you need to know about this? The choice of tools and materials is mainly determined by the method of removing whitewash from the ceiling. For the dry method, it is necessary to prepare a spatula, sanding paper or scraper with a special collection in which the whitewash to be cleaned will accumulate. The wet method of removing whitewash involves using water, a spray bottle, a paint roller, a brush or a sponge. Additionally, a scraper and spatula may also be required.
How to remove whitewash from the ceiling quickly and without dirt with your own hands? In hardware stores today you can easily find special products and solutions that greatly simplify the process of removing ceiling coverings.
Dry method
What makes it special? The choice of whitewash removal method directly depends on the size of the room. If the work is carried out in a small room, then it is best to use the dry method.
To do this, you need to use a wide metal spatula. Using it, layer by layer, the whitewash is removed from the ceiling. All irregularities and defects that arise are cleaned using sandpaper.
The advantages of this method are:
- simplicity;
- no need to purchase additional products to remove old coating.
However, the dry method also has its disadvantages. It is quite labor-intensive and complex. In addition, during work, a huge amount of lime dust appears. Experienced craftsmen know ways to eliminate all these shortcomings. You can put a special box on the spatula. You can really make it yourself or buy it in a special store. This device helps to avoid dust accumulation on surfaces. You should also use any container of suitable size instead.
You can simplify and speed up the process of removing plaster by using a grinding machine. This device helps to find the answer to the question of how to quickly remove whitewash from the ceiling. Reviews from experts confirm that such a device is ideal for large areas. You can avoid the appearance of a cloud of dust by applying water from a spray bottle to the whitewashed surface. Once the material is saturated, it can be easily removed using a spatula or scraper. When using this technology, it is not recommended to soak a large section of the ceiling at once. It is best to divide the entire area into several sections and process them in turn. Whitewash, as a rule, is soaked in 5-10 minutes. This method is recommended for use in small rooms or on surfaces with a small layer of whitewash. Only in this case will you be able to avoid the appearance of large amounts of dirt.
Do you want to know how to easily remove old whitewash from the ceiling? Experienced craftsmen advise tapping the old coating with a hammer. This method works well to get rid of whitewash applied in a thick layer. The lagging pieces are then easily removed using a regular spatula.
Wet method
To remove whitewash, you can try using a simple wash. This procedure is carried out using a brush or a hard cloth. The main advantage of this method is its high efficiency. However, it also has a significant drawback: washing off the whitewash leads to the appearance of a large amount of dirt. To get rid of it, you need to use a washing vacuum cleaner. It is worth remembering that lime can negatively affect the condition of the household appliance.
Application of special solutions
Let's look at this in more detail. How to remove whitewash from the ceiling quickly? There are special solutions that help remove limescale quickly and effortlessly. You can prepare them yourself. The choice of components will depend on the type of coating that needs to be removed. Chalk whitewash can be removed with a simple soap solution. To remove limescale, it is better to use solutions containing acids. Experts recommend preparing whitewash removers in small portions and testing their effectiveness on a small area of the coating.
Recipes
Today there are quite a lot of them. Let's look at some of the most effective recipes for removing whitewash from the ceiling:
- Take 5 tablespoons of soda ash and 2 tablespoons of grated laundry soap and dissolve them in 10 liters of water. The concentrate is applied to the ceiling using a roller or sponge. The product is left on the surface until completely absorbed. When the whitewash swells, it is removed using a scraper or spatula.
- Mix 1 tablespoon of acetic acid and 2-3 caps of bubble bath. Dissolve the resulting mixture in 5 liters of warm water. The resulting solution is applied to the ceiling and left on the surface for 10-15 minutes. When the whitewash swells, it can be removed using a hard rag or spatula. This product is suitable even for large rooms, but in this case it is better to divide the surface into sections of up to 5 square meters.
- Pour a 3% solution of hydrochloric or acetic acid into a bucket of warm water. Treat the whitewash with the resulting solution, and then remove it with a spatula.
Paste
How to easily remove whitewash from the ceiling? Using a paste helps achieve amazing results. To prepare this substance, you need to mix 1 liter of water and 2 tablespoons of starch. First, it is better to dissolve the powder in a small amount of water, and then pour it into the remaining volume until a liquid jelly forms. The paste is evenly applied to the ceiling surface using a soft cloth or brush. The composition is left for some time until the whitewash is completely saturated. The uniqueness of this substance lies in the fact that after hardening it turns the entire layer of whitewash into a crust, which is then easily removed with a spatula.

Alternative Methods
Are they effective? Very often, novice craftsmen, in search of an answer to the question of how to remove whitewash from the ceiling, decide to use alternative methods. In practice, they are used quite rarely, but in an atypical situation they can be very useful.

- removing whitewash using a regular or washing vacuum cleaner;
- creating a cardboard crust on the ceiling;
- using a grinding machine.
If you decide to remove whitewash from the ceiling with a vacuum cleaner, then first of all you should consider choosing the appropriate mode. When using conventional equipment, as a rule, a jet of air is used. It is used to evenly distribute water over the whitewashed surface. Subsequently, the lime layer can be easily removed with a sponge or spatula.
You can also use a washing vacuum cleaner to remove whitewash. A full tank of water is filled into the household appliance. After this, it is turned on and the brush is moved over the limestone layer. The vacuum cleaner will begin to spray water. A layer of whitewash will absorb it. This method is considered the fastest and cleanest. However, this method can lead to clogging and damage to the household appliance. This is due to the aggressive properties of lime mortar, which can easily damage the rubber elements of the vacuum cleaner.
The simplest and most effective alternative method for removing whitewash from the ceiling is to use a sanding machine. When using this device, one of the most important factors is the correct equipment. The technician must wear protective clothing, a respirator and goggles. It is also recommended to close the room tightly and cover the furniture. After this, the grinding machine is turned on and the disc is passed over all whitened surfaces.
