In many apartments and private houses, the decoration of the wallsin former times was carried out with the use of lime, which whitened all the need for this surface. In modern construction stores a wide variety of finishing materials is offered, which, in comparison with whitewashing, have multiple advantages. When planning repair work, the owners face the need to clean the walls and ceiling of the lime. 
All methods, like the ceiling, are usually dividedinto three main categories: adhesive, wet and dry. Before finishing, it is necessary to clean the walls from the remnants of the old coating. There are several ways to remove whitewash from walls. Each of them has both advantages and disadvantages.
Dry method of removing whitewash
Scheme for removing lime from the walls: a) removal using a roller; b - removal with a brush. The fastest way to remove whitewash from the walls is using a grinder. This tool allows you to perform work fairly quickly and qualitatively, but we must bear in mind that the premise before the start of work should be freed from furniture, household items, which can be spoiled by calcareous dust. Windows and doors should be better curtained with building film. Indoor workers should wear respirators, eye protection glasses. Since dry whitewash clears at cleansing, it is necessary to protect the eyes. Actions should be as follows: grinders are fixed on abrasive coarse-grained paper. Try to walk gently on the ceiling, walls with rotational movements. When the largest pieces are removed, clean the surface of walls and ceiling with lighter, grinding movements. 
The fastest way is to use a grinderor a sander. When the work is over, all debris must be swept out of the room, and the floor will have to be washed several times. Thorough washing will be required as the lime will leave a white residue. But you can do it easier and cover the floor before starting work with a construction film, the same as that used to curtain windows and doors. Along the perimeter of the room, the film is fixed with construction tape. The same film can be used to cover the furniture, which, due to its dimensions, will be difficult to take out of the room. It is also advisable to wrap the furniture wrapped in film with tape. A kind of dry method: you can manually remove whitewash from walls and ceilings using a spatula. You can also use it in cases where the old lime hangs down in pieces, and continue working with a grinder. Back to the table of contents</a>
How to remove lime from the walls in a "wet" way
If the grinders are not in the property and failedfind such a tool for temporary use, you can do as you did before repairing housewives. This will require the following things: 
In order to whitewash easier to move away from the ceiling, it should be wet with a sponge.
- a large foam sponge;
- suitable water tank;
- rags;
- putty knife;
- roller on a long handle with a foam sleeve.
Pour water into the container and dip a sponge into it. Lightly squeeze, so that water does not pour on the floor. Use a sponge to moisten the walls properly so that the lime is saturated with liquid. In whitewash, the water absorbs quickly, and the operation will need to be repeated several times. To work it was more convenient, take a roller with a long handle. Follow the traffic from the corners of the room. When the layer of lime is properly soaked with water, try to remove it with a construction spatula. Such cleaning is considered more time consuming, since it will take a lot of time and effort to work. Back to contents</a>
Removing the whitewash with a special solution
One of the most effective ways,To remove lime from the walls, it is considered to perform work with the use of a special solution. You can make it yourself or purchase a special mixture in the building materials store. For cooking, you will need: 
Scheme of cleaning the wall from whitewash: a - cleaning; b - smoothing; c - moving the tool.
- several liters of water;
- ammonia (can be found in the pharmacy);
- soda (diluted with water 1: 3);
- foaming agent (foam for a bath - 3 caps);
- 9% vinegar - for every 5 liters of water, a tablespoon is enough.
Mix all ingredients in one container -an ordinary bucket will do. Take the atomizer (for it you can use any empty bottle with a sprinkler left after household chemicals). Sprinkle the surface with a spray gun. You can also take a roller instead of a sprinkler. Before starting work, preheat the prepared solution to 50 ° C, but do not put it on the fire - just warm the water separately and add to the mixture. Consider this during the breeding of the compound. For example, instead of 5 liters, pour 3 liters of water, and then add the remainder in a hot form. When the walls are wetted with hot liquid, whitewash swells and it can be safely removed from the surface with a spatula, rag, metal brush. Cleaning should be carried out until you can not remove from the wall as much as possible. To check the quality of cleaning, you can from time to time carry the wall with a damp cloth. If there are traces of lime on it, it means that the work should not be stopped yet. 
If the whitewash layer is too thick, you need touse a scraper or wire brush. For, you can make a solution of hydrochloric acid and aqueous vitriol. Add a weak, 2% acid solution in the same amount to one part of the vitriol, do not heat. Moisten the surfaces, leave for a quarter of an hour. You need to use a sponge or roller for this, the spray is not suitable - the vapors of the substance are very toxic. Remove swollen lime with a spatula, rinse with water and scrub with a metal brush. Wash the cleaned surface with plenty of water. Use gloves and goggles when working, make sure that the substance does not come into contact with the skin. Another simple recipe for a solution for removing whitewash: mix 2 tablespoons of grated soap, 5 tablespoons of baking soda, 10 liters of water. Apply the mixture to the walls and clean when the lime gets wet. Back to the table of contents</a>
