After applying to the surface of the liquid, you need to wait a little while the old coating absorbs moisture and becomes soaked. Old whitewash should be removed with a hard spatula.
To the old coating does not scatter around the room, you can collect it in a pallet. What remains after cleansing with a spatula is removed with a damp sponge.
When preparing the ceiling, carefully remove the remains of the old whitewash. If this is not done, the new coating will be of poor quality.
It is necessary to remove dirt, grease stains, soot. To do this, you can again walk through the soapy solution.
After the ceiling has been cleared of various stains and old plaster, it must be properly treated with a special compound. It will prevent the appearance and spread of the fungus.
If on the surface there are joints of plates, then they need to be glued with tape. All cracks, unevenness should be putty.
When the putty dries, you can walk on it with sandpaper to smooth out any irregularities.
It is necessary to treat the ceiling with a primer so that defects do not appear on the new ceiling.
It is strongly recommended not to lime the impure ceiling covered with chalk and vice versa.
To find out what the surface was covered with, you need to wet the old coating and drag it with your finger.
Calcareous whitewash will leave no traces. Cretaceous whitewash erased and left on the finger traces. What you need to do to prepare the ceiling for whitewashing has gone right, you can clearly see the video.
How to whitewash the ceiling?
Coating the ceiling with whitewashing has advantages over other types of surface design. After whitewashing, the pores are not closed at the ceiling. Through them, moisture is absorbed and evaporated.
In addition, this coating has disinfectant properties.
Unequivocally you can not answer the question, what coverage is better - whitewashing of the ceiling with chalk, lime or water-based paint.
Each coating has its own characteristics:
- Chalk is a natural material that has long been used by man in various spheres. It is chosen if it is necessary to create in the room an atmosphere of freshness, bright whiteness;
- Lime - has bactericidal properties. If there are cracks on the surface, then they can be masked by lime. To achieve a beautiful bluish hue, add a few drops of blue in the solution;
- Water-based paint - this type of coating will last a long time. When choosing a paint, you can use any shade depending on the interior.
Cretaceous solution
To whiten with chalk, you need to prepare a chalky solution - you need 5 liters of warm water. It needs to dissolve 30 g of joinery glue and 3 kg of chalk.
Chalk must be sieved beforehand so that there are no unnecessary inclusions.
A few drops of blue should be added to the finished solution. It will not allow the coating to turn yellow with time and will emphasize the whiteness of the ceiling.
With this amount of solution it will be possible to bleach about 11-12 m2 of surface.
Limestone solution
In 1 liter of water, it is necessary to dilute 3 kg of lime slaked. Add 70-100 g of table salt and about 200 grams of aluminum alum.
If the surface should have any shade, then it is worth adding a dye. All components must be mixed well, then pour in water. The total volume should be 10 liters.
Before applying the lime mortar to the ceiling, the surface must be moistened. So lime is better to go to bed. For humidification, a spray can be used.
To lime or chalk, it is not enough to prepare a solution that will cover the surface. It is necessary to prepare a number of tools. To handle the ceiling you need brushes, roller.
It is possible to use an airbrush, a vacuum cleaner that is equipped with an air blowing function.
Brush, which will be applied whitewash, must be prepared.
Before work, it is recommended to soak for a couple of hours in warm water.
Thus, the handle from the tree swells, the bristles will be securely fastened. During the work they will not remain on the ceiling.
If you use a roller, whiten will be faster. A spray gun in small rooms is not recommended, since the solution will fall not only on the ceiling, but also on walls, floors, surrounding objects.
Ceiling whitewashing
You can whitewash the ceiling with those who have the skills to carry out such work. If there are no skills, then it is better to use a roller. Before applying the mixture, it must be mixed well.
Only so the hue of the surface will be uniform. You do not need to get a lot of solution on the roller. The coating should be thin.
After applying the first layer, the ceiling must dry. Only on a dry surface can apply a second layer.
Video:
When working with a brush, the first layer is applied along the visible sunlight. After drying the layer is applied the second - across the rays. So the coverage will be even, brush strokes will not be noticeable.
Whitewashing the ceiling with your own hands, using a vacuum cleaner, gives a flat surface, whitewash will lie perfectly. To carry out the work, it is necessary to have a vacuum cleaner with an air blowing function.
Most often, a special lid with tubes is included in this kit. It should be put on the jar in which the solution is poured and connected to the hose of the vacuum cleaner - a spray will be made.
Under pressure of air, the solution is drawn into the tube, then it is sprayed out.
When applying whitewash with a sprayer, the solution should be well stirred. It is important not to allow the appearance of droplets on the ceiling, since after them the stains will remain on the surface.
When sprayed, the mixture is applied in a circular motion. After applying one layer, whitewash should dry. Apply the next layer on the dried ceiling.
If there are irregularities, defects, then whitewashing with a vacuum cleaner will help to hide them, because on the ceiling there will be 3 or 4 layers of whitewash.
Coating of the ceiling with water-based paint
Water-based paint can be applied to the surface of a very thin layer and get a uniform color.
The application of this coating on the ceiling has many advantages:
- The paint dries quickly, already 2 hours after the work, the ceiling is ready for use;
- The paint does not have a sharp specific odor, therefore it is not necessary to leave the house for the time of painting;
- Water-emulsion does not contain harmful substances that have a negative impact on the health of people and animals;
- This paint can cover any surface;
- Water-based paint can be washed easily from hands, surfaces, if it does not dry out;
- Due to the latex component, the water-based emulsion has water-repellent properties, it can be treated with water.
The paint consumption is easy to calculate - this information is usually indicated by the manufacturer on the bank. There may be a small deviation from the data indicated.
It depends on how much it absorbs the surface.
It is recommended to use a roller when working with water-based paint. But you need to choose not foam, but fur. Roller made of foam rubber will absorb the paint very much.
In addition, it forms bubbles during operation.
Brush to paint the ceiling is not recommended, since it will leave tracks, bristles. From the paint gun will remain unevenly painted places. Still, a thin brush will have to be bought.
She will need to paint the places where the roller is difficult to get.
Before you start painting the ceiling, the surface must be prepared. From the surface, the old coating is removed, while the sprayer is used.
If there are cracks, defects, then they need to be plastered and primed.
It is recommended that you read the instructions carefully before applying the paint. There are water-emulsion paints, which must be diluted with water by 5-10%.
After the paint is ready, it is necessary to paint the ceiling along the entire perimeter with a brush. After that, you can start painting the roller and do not worry that the walls will be stained with paint.

It is recommended to apply two layers of water-emulsion. So the coverage will be uniform.
Before applying paint to the ceiling with a roller, the tool is lowered into the paint and squeezed out well.
Specialists recommend to paint with a roller, which has a minimum amount of paint.
It is better to dunk the roller more often in water emulsion.
When painting, it is impossible to strongly press the roller so that no streaks form. After drying the first layer, it is necessary to apply the second and third.
