How to wash off the whitewash from the ceiling: methods and means
Quite recently, whitewash was the main ceiling coating, now various types of coatings are used for this. When making new renovations, in many cases the old whitewash is removed from the surface. Considering the fact that they are removing it from the ceiling, this is not very convenient to do. It is necessary to figure out in which cases the whitewash is washed off and what is the best way to do it.
Features of pollution
When carrying out repair work, much attention is paid to finishing the ceiling, because every detail in the interior should emphasize the general idea of the design. The upper part of the room should be in harmony with the overall style of the room.
Not so long ago, only whitewash was used to decorate ceilings., but in modern design, special attention has been paid to these surfaces. Suspended ceilings, plasterboard or expanded polystyrene boards, decorative plaster, different types of wallpaper, painting - this is not a complete list of how you can change the appearance of the ceiling covering of a room and transform it.
In order to prepare the surface for painting, wallpapering or other decorative coating, a layer of whitewash is washed off from the ceiling. It is quite easy to do this, but given that you have to work with the ceiling, the work is a little more complicated. It should be immediately announced that whitewash should not always be removed from the surface. For example, this is not done when installing a suspended ceiling or tension structures. You can also whitewash the ceiling again if the old coat remains in good condition.
Before applying a new layer, the surface is cleaned of dirt., the ceiling is washed with a wet sponge. When applying a new layer, take into account what the previous layer was whitewashed - it can be lime or chalk. When applying a new layer, it should be borne in mind that chalk should be applied to the chalk whitewash, lime should be applied to the lime.
To determine which layer was earlier, the ceiling is sprayed with water. If water droplets hang on the surface, the ceiling has been whitewashed. If the water is immediately absorbed into the surface, then chalk was used to whitewash it.
Be sure to remove the whitewash:
- if mold appears on the surface;
- painting with water-based emulsion is planned;
- wallpaper will be glued;
- if polystyrene foam boards are glued to the ceiling.
Removing the ceiling trim is an important step. If the whitewash is removed incorrectly or poorly from the surface, then wallpaper, paint or any other type of finish will not adhere well.
Materials and tools
It is unlikely that it will be possible to remove the old layer without dust, so you should thoroughly prepare for work. Extra things and furniture, carpets are taken out of the room, curtains are removed. Bulky items or furniture that are difficult to take out are covered with foil. A polyethylene covering should be laid on the floor, newspapers can also be laid out, which will absorb excess moisture.
There will not be a lot of dirt on the walls during work, you just need to wipe them with a damp cloth. Garbage bags should be prepared in advance to quickly remove old newspapers and film in them after completion of work.
Such work is rather dirty, so it is better to prepare special clothes, put a scarf or cap on your head. Be sure to wear protective goggles and use a respirator.
In addition to working clothes, you should prepare tools that will be needed during work.
During work you will need:
- putty knife;
- sponges, rags;
- sprayer for wetting the surface;
- ladder;
- container with water;
- gloves.
If you don't have a ladder, a stable table and chair will work, but it's not always safe to use them.
During work, doors and windows should be closed so that lime dust does not penetrate through them into neighboring rooms. Considering that this work is very dusty, you should put a wet rag on the threshold so that when you leave the room, dirt from your shoes is not carried out of the room.
Of course, this is a basic list of required tools and preparatory work. A more accurate list of them may vary depending on the state of the surface.
The ways
After the necessary protective equipment, tools and clothing are prepared, excess furniture is taken out of the room, the floor is covered from dirt, and the main work begins.
The ceiling is cleaned dry and wet. For dry washing, use a sander and spatula. With the wet method, lime is washed off with water or chemical solutions, home remedies. The wet method makes it easier to clean the surface, but there will be a lot more dust in the room and a lot of dirt on the floor.
The choice of cleaning method depends on what type of whitewash was used earlier. If you run your palm over a chalk surface, a white mark will remain on your hand, there will be no such trace from lime. Often ceilings are painted with water-based emulsion. When you slide your hand over the painted surface, there will be no trace on your hand.
To make sure that the ceilings are not whitewashed, but emulsion paint, you should wet a sponge and rub a small area. In the first case, there will be no obvious traces of paint on the sponge, and the wall will wash a little.
It is necessary to dwell in detail on what methods are used to correctly and quickly remove whitewash from the surface.
Wet
Old whitewash is removed with water. This method is used quite often.
The following tools should be prepared for it:
- roller - for such cleaning, a device with an attached pallet is used, where garbage immediately gets;
- spray;
- rags, rags;
- putty knife.
If you need to remove the old coating, the ceiling is moistened using a spray, a wet roller is also suitable for this. When applying water to the surface, you need to make sure that it does not drain, so apply it sparingly. After 10-15 minutes, the ceiling is moistened a second time.
With a spatula, remove the old layer of whitewash from the ceiling. If, during work, a solution will drain on it, it means that the surface has been moistened very much, you need to wait until the surface dries out a little.
It is more convenient to apply water to the walls and ceiling with a spray gun. When working with a roller, you can overdo it and the liquid will drip into your face. Moisten the ceiling evenly so that the whitewash can be removed from the surface in one layer. Often, during work, the ceiling is moistened on one part, then they move to another part and continue to work there, during which time the whitewash is sufficiently saturated with moisture.
The work is done while standing on a stepladder. Before starting it, make sure that the ladder is stable. It is good if at this time there is an assistant nearby who will insure that the ladder does not stagger.
Using a spatula, remove a thin layer from the ceiling. When all the whitewash has been removed from the surface, use a damp sponge to wash away the remaining layer. When the ceiling is dry, check how well the work has been done. To do this, hold it with your palm across the ceiling. If there are no traces of whitewashing on it, then the work has been done perfectly.
Sometimes a spatula is not used for this method. With a thin layer of whitewash, remove it with a wet rag. The most economical option is to wash the surface with plain water. Such cleaning will be the cheapest, although this method will require the use of physical force.
Water is poured into a bucket, they take rags and brushes and wash off the whitewash from the ceiling. When flushing with water, flush the instrument more often and change the water. To make the work less laborious, it is better to use a warm liquid. It is difficult to wash chalk and whitewash from the ceiling in this way, especially since during work the chalk solution will always get on the face, and this greatly complicates the work. It is best to use this method on a ceiling with a thin layer of paint.
This method has a drawback - unfortunately, you can't do without dirt here. In addition, it will not be possible to completely remove the entire layer from the surface in this way. As already mentioned, the floor should be covered with plastic wrap or newspapers. This will significantly reduce the time spent cleaning the premises after work.

Places where the old whitewash already does not hold well are pushed off with a narrow spatula. Use a wide spatula to clean the surface, taking care not to damage the putty during work. It is much more convenient to work if you put something like a scoop under the spatula, then all the whitewash will remain there, and will not fall down.
This method can be slightly improved. and make your own surface cleaner. A hole is drilled in a spatula, a wire or braid is passed through it and a bath is suspended, where all the dirt will fall.
