About ten years ago, the main tool for decorating the ceiling was ordinary whitewashing, which was applied with a special brush or using a spray. Modern technologies allow you to create a new design of ceilings, but for this you need to remove the old whitewash as high quality as possible. Gluing the ceiling with polystyrene tiles, coating the surface, painting with water-dispersion paints - all these types of finishes require the preparation of the base and the removal of lime with the highest quality.
There are many known methods for removing old calcareous coatings. The most common of these is flushing whitewash with water. The procedure will require a lot of time and physical effort, but the result is worth it if you plan to make a spectacular and quality repair. First of all, it will take a lot of time to apply water to the ceiling with a spray gun and then remove the wet whitewash with a metal spatula. For maximum effect, work should be carried out in sections and not allow drying of wetted surface areas.
Tools for removing old coatings
If you do not know how to wash whitewash from the ceiling, remember that before you begin to work, you must prepare all the required tools. This will facilitate the work and allow once again not to look for a spatula or sponge in the apartment soiled with lime.
You will need the following tools:
- a spatula of medium width to remove the composition;
- a spray with water to wet the ceiling and soften the whitewash layer;
- a respirator to prevent small particles from being suspended in the respiratory system;
- to protect the head, hands and other parts of the body should wear a scarf, gloves and work clothes;
- A film or paper will help protect furniture and floors from contaminants so that after work they won’t puzzle over the question: "How to wash it all off?" (to solve the question of how to wash whitewash from the ceiling is much easier than washing it off the floor and furniture);
- and do not forget about the stepladder, since without it you are unlikely to reach the ceiling, and the use of a table and chairs in this case is undesirable from the point of view of safety.
This method is most accessible for those who do not have the appropriate skills on how to wash whitewash from the ceiling. The main disadvantage of the technology is the formation of a large amount of dirt in the room, which can be difficult to remove.
Other whitewash removal methods
If the above method does not suit you, you can try other methods:
- The removal method using a paste is the process of wetting the ceiling with a liquid solution designed for wallpapering, and further cleaning with a spatula. With this method, lime whitening does not turn into small particles, and the suspension does not thereby pollute the space.
- Soap removal. To make the solution, you will need 3 tablespoons of crushed soap, 10 liters of water and a few tablespoons of salt. The resulting composition is necessary for wetting a large sponge and washing off whitewash without the help of a metal spatula.
- If you do not know how to wash whitewash from the ceiling, and any of the methods associated with the formation of a large amount of dust in the room is unacceptable for you, then use a deep penetration primer. Simply apply the compound to the ceiling and continue to finish on top of the old calcareous coating.
The prepared base can be subjected to any further decoration: painting with a roller, wallpapering or tiling, installation of suspended ceilings. To wash off or not to wash off the whitewash is up to you, but if you take such a serious matter lightly, you can get serious problems. For example, whitewashing can fall off in a thick layer and damage the new ceiling decor . Finishing the ceilings in the apartment is a difficult process, if you doubt your abilities, invite specialists.
