It is difficult to find a person who has not heard anything about water-based paint. Painting the walls with water-based paint allows making the apartment beautiful and cozy.
For painting the walls of the bathroom use water-based paint.
For the decoration of walls, a huge number of different types of building materials are offered. With their help, you can create any design. Painting of walls with water-based paint does not lose its relevance due to its availability, simplicity and ecological purity.
Features of choice
Water emulsion paint is an aqueous mixture of the smallest polymer particles and various additives. All these components are suspended. The basis is composed of polymeric substances that form a film when dried. To impart a white color to the composition includes zinc oxide or titanium dioxide. In addition, various fillers, plasticizers, antiseptics, etc. are added. As a thickener, a glue composition (usually CMC glue) is used.
Table of types of paints for different surfaces.
The paint thinner is water. The most common composition is as follows: polymer substance - 50%; pigment and filler - 37%; plasticizer - 7%, other elements - 6%.
Depending on the type of polymer used, modern water-based paints are divided into the following types: acrylic, silicone, silicate and mineral. The greatest application is acrylic water-based paints, based on acrylic resins. Latex is added to high-quality colorants. Coatings with such a paint have sufficient water resistance, has a density, have good adhesion with many materials.
Silicone paint refers to coatings that form a vapor-permeable layer. This allows you to apply the material on the walls of premises, where often there is increased humidity. It is resistant to the formation of fungi and mold. Due to its density, the paint can mask cracks up to 2 mm. The disadvantages include increased costs.
Silicate water-based paints basically have a liquid glass with colored pigments. They have increased resistance to the effects of atmospheric factors, very high permeability for steam and air. Its service life is quite high. On moisture resistance this type is slightly inferior to silicone paint. Mineral water-based paints can include slaked lime or cement. Therefore, this paint easily lays on the concrete walls. Polyvinyl acetate paint, belonging to this type, has a high strength after the formation of the film, it withstands enough exposure to water, fats and oils. An important positive property is high light fastness.
Water-based paint has a number of parameters that should be taken into account when purchasing it for painting walls. The main characteristics include:
- the basis of paint;
- the expense at painting;
- viscosity at realization;
- specific gravity;
- shelf life;
- shelf life.
Tools for painting the bathroom.
The quality paint has a consumption (when painting in one layer) 150-200 ml / m². The specific gravity should be about 1.35 kg / l. The drying time should not exceed 24 hours. At the same time, high-quality paints dry up in 2 hours.
Water-emulsion paint is realized in polymeric or metal containers of different volume. The factory capacity is given instructions or recommendations for use. Including usually indicated expense, which allows you to estimate the amount of paint needed to purchase.
In addition, the water-based paint is realized in different consistencies. It may already be ready for use (indicated in the instructions) or requires stirring in water to a suitable consistency. If the paint is too dense, then it must be diluted with water and evenly mixed. Usually, before painting the water-based paint on the wall, the building material is mixed manually until the consistency of the milk. However, the best option is mixing with a mixer or an electric drill with a mixer paddle. If a volumetric texture is provided on the wall, the material is not diluted, but applied in a very thick form. Immediately before application to the walls, the emulsion must be re-mixed thoroughly.
Painting the walls in the bathroom helps protect them from moisture.
In the case where the painted walls must have a certain color, you should take care of the color in advance. Currently, there are water-based paints of different colors on sale, but if you do not find the right color, you should take a white paint and add the desired color or a combination of several colors. When selecting the right color, you should first check in a container of not more than 100 ml. The color is gradually added to the paint with thorough mixing. Periodically, control smears are made. When the desired color is reached, the desired color concentration is fixed. Only after such a check is the coloring of a larger volume of paint. It should be borne in mind that the color of the paint changes when it dries, so control smears should be allowed to dry.
Preparation for painting
Modern water-based paints are able to lie almost on any surface, including concrete. However, all the roughness of the wall will manifest through the coating. This requires preliminary preparation of the wall surface before painting. The surface of the wall should be smooth and even.
To do this, a thin layer of finishing putty on the entire surface is applied. After the drying of the putty, the grouting and grinding of the wall is carried out with a grinding net or a small emery cloth. Directly before painting with water-based paint on the walls, they must be cleaned of dust.
The wall itself must be freed from any objects (including nails, screws, etc.). The space in front of the wall must be free of furniture. The floor area, plinth is recommended to close the film from splashes.
Painting with water-based paint on walls or ceiling can be done with:
- paint brush;
- paint roller;
- spray gun.
To apply a three-dimensional texture, a sponge is used. The most uniform and fast painting is carried out by a spray gun, but not all have it. In addition, to use it you need certain skills of the painter. In order to paint the paint paint the walls with water-based paint, it will take a very long time. Therefore, the paint brush is used for tinting in hard-to-reach places, as well as in the corners of the wall. In order to paint the water-emulsion paint of the wall, it is necessary to have paint brushes of different widths (from 2 to 10 cm).
The most common painting with a paint roller. It is best to use a roller with a soft pile medium length (about 16-20 cm).
The process of staining
It is recommended to paint the water-based paint of the wall in three layers. The first layer (leveling) acts as a primer. Accordingly, the quality of this layer does not put forward high requirements. Its task is to impregnate the top wall covering to ensure good adhesion to the base layer, if necessary, to paint over small defects. The main condition - there should be no drips, rushes, drops. The layer should provide a flat surface.
The second layer is applied after the first layer dries (after 2-4 hours). It should ensure an even color throughout the wall surface. Finally, the last layer is superimposed for the final saturation of the color of the wall and the provision of an even film of paint. The wall is generally recommended to paint with a roller. The corners of the walls, areas near the baseboard, the upper boundary in front of the ceiling, hard-to-reach places (behind the heating battery, niches, etc.) are painted with a brush.
Painting begins with the painting of the corners with a brush at a distance of at least 5 cm in all directions from the corner. Then the brush is applied to the areas adjacent to the door and window openings. All hard-to-reach places are painted. After that, the whole surface of the wall is painted with a roller. The site in front of the baseboard and near the ceiling is painted with a brush.
The order of work with a roller is as follows. The paint is poured into a wide container (for example, a basin). The roller is dipped into the paint and rolled on the plane (plywood or something like that) for even distribution on the roller. Surplus is removed with a roller by means of the edge of the container. When painting the movement of the roller should be vertical. Each subsequent smear should overlap the previous one by 3-5 cm. Painting starts on top of the wall. Periodically immersing the roller in the paint, paint the entire surface of the wall. When there are streaks, they should be removed immediately by moving the roller. A separate layer of paint should have a minimum thickness sufficient to ensure uniform color. The recommended direction of painting the wall is from the window to the door.
When painting and during the drying of paint, you should eliminate the possibility of drafts.
Anyone can paint the walls with water-based paint. This process is fairly simple and does not require special skills. The main thing is to choose a high-quality water-based paint and carefully put it on the wall.
