1. oil paints (made on the basis of drying oil);
2. enamel paints (made on the basis of varnishes);
3. adhesive paints (made on the basis of aqueous solutions of some organic polymers);
4. water-based paints (made on the basis of aqueous dispersions of polymers).

We will consider each type of paint separately.

Oil

More recentlyOil paint was the most popular of paints and varnishes. The whole reason was the lack of an alternative. She was painted everything: floors, windows, doors, walls. After fruitful work, I had to wait a long time until the surface dries. And then, after a few years, the painting process had to be repeated anew. The blame for the poor air throughput. Simply put, the painted surface does not breathe and does not let air through, which eventually leads to cracking and shedding of the material.

Increasingly, this paint is used when painting metal surfaces. In everyday life, it is hardly possible to meet it now, since it emits a persistent specific smell that can harm people's health. In addition, in recent years, more and more often, they prefer more environmentally friendly material when repairing internal surfaces, but oil paints do not lose their popularity ... They are made on the basis of artificial and natural drying oil. It is considered to be one of the most durable paints and varnishes. They are densely grated and ready for application. Thickly grated before application are bred in the required proportion. Drying oil, which is part of it, can be sunflower, flaxseed and hemp. The first provides faster drying compared to subsequent ones.In accordance with GOST, the following grades of oil paint are produced:

1. MA-021 - on natural drying oil.
2. MA-025 - on the combined drying oil.
3. GF-023 - on glyphthalic drying oil.
4. PF-024 - on pentaphthalic drying oil.

Enamel

Enamel paints are paints based on varnish. They can be represented by alkyd enamels, nitro enamels, polyurethane, perchlorovinyl, melamine and other paints. Available in special containers after opening which are ready for use. Dries up within 24 hours. It is stored and suitable for use within a year after manufacture. Suitable for painting walls, metal and other surfaces. Bred with special solutions. To achieve the best paint effect, the surface should have a roughness, which will provide the greatest area of ​​contact with the components of the paint.

Glue

The main component of glue paint is glue. In addition, it includes aqueous solutions of cellulose ethers, starch, polyvinyl alcohol, casein. In its preparation, three containers are used. The first of them is for chalk. They put it in it and fill it with hot water. The ratio of the amount of chalk to the amount of water should be as 2 to 1. This solution can withstand about two hours. A dye is placed in a second container. It is similarly diluted to the density of the dough and knead until a homogeneous mass is formed. In the last container, glutinous water is prepared per 0.6 kg bucket of water. glue. The resulting mixtures from the first and second containers are mixed. A test is made for the density of the formed material. To do this, take a stick with a pre-treated surface. It is placed in the resulting mixture. If it is painted evenly and there are no unpainted gaps on it, then it is considered that the color has normal density. In the event that the color is liquidish, chalk and dye are added to it. If too thick, then a little bit of water is added.

The resulting color is applied to a wall, plywood or other flat surface in order to check the color of the resulting mass. They let it dry and only after that they start painting the main walls.

The final step is to mix the color with the adhesive component. If the glue is very thick, there is a risk of shedding paint in the near future. Otherwise, it is possible to modify the color scheme of the paint under the influence of external environmental conditions. Therefore, a qualitative reaction to the correct combination of paint components is first its thickening, after its liquefaction. Moreover, it should flow down the brush or stick in jets. It is strictly forbidden to dry the painted surface in a draft.

Water emulsion

In water-based paints, the main element is water, while it dilutes rather than dissolves the components in the mixture. After application to the surface to be painted, water evaporates. It is suitable for painting most surfaces except metal, since it causes premature corrosion on them. The exfoliation process is not characteristic of paints of this variety. It dries quickly. It does not cause allergic reactions, harmless to humans and animals. Does not damage the environment. There is no pungent, everywhere penetrating specific smell. It has a variety of colors thanks to coloring pigments. Their mixing allows you to create colors of different colors and saturation, thanks to this you can create a diverse and contrasting interior of any room. As a rule, paint is sold in standard white color. When buying it, a store specialist will help you choose the right color scheme with the help of ready-made sketches for paint. The process of applying it to the wall does not require much effort and time, and the tool used is easy to clean in water.But along with all its advantages, a significant minus is that it can be applied to the painted surface only at air temperatures of +5 degrees. Otherwise, the desired effect will not be achieved and will have to redo the work again.

Before painting the walls ...

One of the most important elements of repair is wall decoration. In order to start gluing or painting them, it is often necessary to prepare the working surface, not forgetting about the painted room. The appearance of the premises largely depends on the quality of these works.

It must be prepared for painting in order not to stain objects and surfaces that cannot be painted. To achieve this goal, you must perform the following steps:

1. furniture and appliances. Whenever possible, all shall be submitted. If difficulties arise with its movement or transportation, then it simply moves to the center of the room or room in which repairs will be carried out, and are covered with a film;
2. carpet. In the possibility of transportation or transfer, it rolls up and is taken out to another room; In the absence of such a possibility, it is covered with a film;
3. laminate, parquet covered with film or newspapers;
4. all extraneous things are removed from the walls, including lighting devices and decorative elements;
5. panels and switches are removed;
6. all places not to be painted are sealed with masking tape.

The impeccable appearance of the walls largely depends on the scrupulousness and thoroughness of the preparatory work done. Otherwise, you have to redo everything again. In connection with these, special attention is paid to the preparation of walls.

Does not require careful preparation of the painted surface decorative paint. And it will be easiest to use it. It belongs to modern new types of paint. Suitable for walls in poor condition. Before painting, make sure that the surface is dry, clean and has good bearing capacity. Also make sure that the painted surface does not have cracks, depressions or other irregularities. Let's consider in more detail.

Walls can be divided into two types:

1. new walls.
2. walls in an old, long-commissioned room.

The first case is the most beneficial. Since most of the worries have already been done. It will only be necessary puttyand then sand the surface to be treated with sandpaper. Then the walls should be washed with a damp cloth and allowed to dry. At the end of work primer, in accordance with the functional characteristics of the room.

The second approach is applied for not new premises. To begin with, you should remove from the walls all that remains of the past interior. Then wash the work surface well, as painting will reveal all the flaws, including small cracks. If the resulting surface has irregularities, then they should be eliminated. A perfectly flat and smooth surface always pleases the eye. Otherwise, when there is no desire to level the walls, decorative structural paint. Her alternative may be decorative plaster.

Walls of bast fiber, gypsum panels and gypsum plaster must be primed in advance with a brush and a flat brush. Otherwise, the surface will absorb the paint too much. It is better to cover the metal surface and other places that have a weakness to corrosion with insulating paint (in other words, resistant to water). An important point! During operation, the room should be free of drafts, and the temperature should not drop below 18 degrees.

If once the surface has already been painted, then it should remove residual material. First you need to determine the type of paint with which the walls are painted. If you rub the painted surface, then the alkyd or oil will fall off, and the water - dispersion will remain. To remove the paint, use a spatula, sandpaper and a metal brush.

If the wall surface has ever been pasted with wallpaper, then their residues are removed with a spatula. If they still do not go away, use water or some other liquid to remove the wallpaper from the wall.

If the working surface is not even enough, we recommend using gypsum plaster. It is well applied, suitable for use by both professionals and novice craftsmen. After its application, the surface is leveled with appropriate putty.

In the event that the wall defects are significant, there are several ways to align them. The first is plasterboard casing. This option is perfect for especially severe cases, as it will not only simplify the process, but also save money. The second option is more traditional - plastering. This method is suitable for surfaces of “average curvature”. Paint has the ability to emphasize any flaws and defects, so before painting the walls it is important to align them very carefully. After quality work on the preparation of the walls, you should go to the direct process of painting the walls.

Proper painting of walls: step by step instructions

1. First, it is necessary to color all internal and external corners, while it is necessary to start work from the side of the window.

2. Next, take a brush and paint the surface that cannot be painted with a roller (corners, baseboards, batteries, etc.). By the way, the floor skirting is best painted with enamel (varnish) paint, and the batteries - special heat-resistant.

3. To obtain a uniformly painted surface, we recommend running the roller over the paint net or board to remove excess paint.

4. Next, we start painting large surfaces. To do this, it is best to use a roller. For best results, we recommend applying the paint in progressive movements from top to bottom, then from left to right and again from top to bottom. That's the whole technology of painting walls.
