Old paint should be completely removed. This can be done with a spatula, carefully cleaning the entire surface.With a brush and a special tool, the ceiling should be primed. After the primer layer dries, the surface must be puttied well, correcting any irregularities and defects. A special base for water-based paint should be applied to the dried surface; this layer is the pre-paint.
Paint selection
Currently, for painting ceilings are used compounds represented in a huge range of manufacturers of paints and varnishes. Each species has its own characteristics, has a number of advantages and disadvantages.
For painting the surface of the ceiling should not use oil paint. The best option are water-based paints, water-based, or, as they are also called, water-dispersion.
Experts recommend to use this type of paint to decorate ceilings in residential premises. because its main characteristics include:
- no sharp odor;
- absolute non-toxicity;
- good adhesion with most building materials;
- the possibility of applying to the old paint;
- practicality in use.
The most popular types of water-dispersion paints are:
- Latex - has a good level of coverage and density, after drying it is not washed off, the surface may be subjected to wet cleaning. In most cases, one layer is enough.
- Silicate - A good option for exterior decoration of buildings. This type of paint is more expensive than its counterparts, as it is based on liquid glass. As a rule, this covering is applied to profile finishing of various surfaces, in warehouse and production rooms. Perfectly covers a surface from concrete or a stone.
- Acrylic The most versatile paint, adapted to different surfaces. This substance can hide minor imperfections of the surface, and textured paint can remove minor cracks or gouges. Acrylic coating dries quickly and does not change color during operation. It has a certain level of resistance to direct sunlight. Of the shortcomings - sensitivity to moisture. The color palette of acrylic paints is huge. All shades can be with a glossy or matte effect.The matte surface is able to visually increase the height of the ceiling, will help to hide some defects. Gloss is suitable for use when painting planes of large areas, requires a perfectly flat surface.
- Silicone Paint creates a beautiful coating that can be washed. This type of paint is suitable for coating surfaces in rooms with high humidity and sudden temperature changes.
Each type of paint, if necessary, can be diluted with water to give the desired consistency. With the help of tinting pigments, you can get any desired shade, it is enough to add the desired amount of dye in the white composition.
How to calculate the flow?
Before buying, it is necessary not only to determine the type and color of the ceiling paint, but also to calculate the required volume, which is due to its consumption. The required amount depends on the size of the room, determining the ceiling area. Usually, all the necessary information for the calculation of the dye composition is on the packaging, therefore, be sure to read the instructions.
In general figures, you can navigate to the following calculations. The average consumption of water-dispersion paint when finishing ceilings is about 100 - 120 g / m2. Depending on the surface, at least, it will be necessary to apply two or three layers for a uniform quality. Material consumption is approximately the same as when using a roller, which is a brush. If we take into account the lack of experience and the inability to rub the paint professionally, then the average consumption will be 300 g / m2.
In any case, these figures are approximate, the consumption depends on many parameters, so it is better to take paint with a margin.
Selecting the desired type of water-based paint, on the package you can read information about whether it requires dilution. If manufacturers recommend diluting the purchased material, you can add water to the right amount of paint, as a rule, no more than 5-10% is required. The prepared volume is best to use immediately, do not give it to thicken again. The best option is considered to be the dilution of paint to the state of liquid cream.
It happens that the material does not require dilution, it is enough just to mix thoroughly.Such manipulations will be enough, if you plan to paint the ceiling in a single layer, in such situations the paint should be slightly thicker.
For the entire surface of the ceiling should be purchased paint of the same manufacturer, the same brand. This requirement is a guarantee of uniform monochromatic coverage.
If you plan to paint the ceiling is not in pure white color, then the tinting is better to entrust the experts, they will help you choose the right shade and mix the components thoroughly.
How to apply?
Paint the ceiling on the old paint is not difficult, it can be done even by an inexperienced person with his own hands. After all stages of preparation you need to start painting.
The best is the coating of paint, consisting of three layers, in this case, you can be sure that there will be no streaks or streaks on the surface. Before applying each layer, the roller must be carefully rolled out in a tray in order to get rid of the excess amount of the coloring composition, due to such manipulations the possibility of smudges is excluded. The first and last layers should be applied perpendicular to the windows, this applies to all types of paint, including acrylic.
When painting, one should not make any sudden movements, it is necessary to drive smoothly with a brush or a roller on the ceiling, slowly, inspecting so that there are no unpainted areas left.
The next layer should be applied only on the dried surface, and it is not necessary to accelerate the process in any way, the paint should dry naturally.
After applying the second layer of paint, it is desirable to exclude the possibility of direct ultraviolet rays, as well as the occurrence of drafts, which will help avoid the peeling of the coloring material from the substrate.
Paint the ceiling can be several types of tools. The most common are the paint brush and foam roller, you can also apply the paint using the spray gun, which is a regular spray. This device helps to carry out the painting process much faster, the main thing that the consistency of paint was appropriate.
When re-painting the ceiling, it is better to use the same color or similar in shade, otherwise you will have to apply a large number of layers in order to completely paint over the previous coating and to achieve the desired result.
