Those who traveled to Europe, certainly paid attention to the simplicity of the situation, which looks stylish and attractive. In ordinary houses you rarely find stretch ceilings, decorative plaster, etc. Instead of wallpaper, Europeans have walls painted in pastel shades, and the lack of luxury is complemented by stylish and refined decor elements. Painting walls includes several stages of work, in addition, it is mandatory to prepare a tool.
Dyeing the walls will help create an interesting design and coziness in any room.
Tools and Paint Selection
For smooth and high-quality painting the walls will need:
Water emulsion paint can be applied both with a roller and with a brush.
- Rollers. There are fur and foam. The former are used to create a structural surface, the latter for a smooth surface.
- Brushes. To determine their quality, you need to check the pile on the fortress, if it climbs, it is better to look at another option.
- Cuvette. This is a container that has a corrugated bottom. At first glance, it seems that you can do without it, but it contributes to uniform impregnation of the roller.
- Plastic spatula.
- Painting tape. It is necessary to protect the unpainted surface and individual elements. If you plan to paint the walls in different colors, you can not do without it.
- Drill and nozzle-mixer for mixing and tinting paints. They allow you to give the paint the right shade and consistency.
To paint the walls in the interior is used water-based paint. It does not smell, dries quickly, is easy to use, rinses well from the body, easily changes color with the help of color, is able to breathe, environmentally friendly and safe for humans. There are 3 types of water-emulsion:
Scheme of distribution of paint on the roller.
The greatest strength is acrylic. It lies flat on the surface, is resistant to burning, has a long service life. In addition, it can be washed and it is resistant to abrasion.
Latex-based paint has the same qualities as acrylic, and creates a strong and moisture-resistant film on the surface. Latex paint after drying forms a thin film on the painted surface, which gives the paint additional strength and moisture resistance.
Silicone paint due to its increased water-repellent properties and elasticity is used in the interior with high humidity.
The walls must be painted at a temperature of +5 to +20 ° C and an air humidity of about 80%. In too warm and dry room, the paint will dry quickly, which places it evenly applied. In addition, the subsequent rows of paint will lie on the already dried previous ones, which forms the so-called rolling, noticeable in the interior after complete drying. You can create the necessary microclimate using an air humidifier or a hot water tank left in the room for a while. Dusts and drafts should not be.
Tools for decoration and painting of walls.
In order to calculate the required amount of paint, the length of the surface must be multiplied by the width. As a result of calculations, the area of the room becomes known. On the bank with paint, the consumption per 1 square meter or the total area of the surface to be painted is mandatory. It should be borne in mind that the painting of walls in the interior requires the application of at least 2 layers. To the general calculation, it is necessary to add another 15-25%, since the expenditure indicated on the bank is approximate and depends on many reasons. Remains of paint in undiluted form have a long shelf life and are always useful for tinting.
Before starting the painting work on the wall, it is necessary to clean off the previous coatings. Wallpaper should be wetted and removed, you can use for this special composition. Whitewash should be washed off with warm water. As for removing old wallpaper, they can be eliminated using a spatula. If during removal some of the wallpaper can not be removed, you can take a special liquid. If the walls were painted with oil paint, it must be cleaned to the base of the wall with a spatula, an ax or chisel. You can not leave even small areas.
Comparative table of paints.
Rusty, fatty and moldy plots are necessarily subjected to special treatment and disposal. Against mold, special fungicidal formulations sold in stores are of great help. Oil stains from the surface can be removed with a 5% soda solution, previously diluted with warm water. Rust is washed with water and primed with 10% solution of copper sulfate. In order to prepare such a composition, it is necessary to dissolve copper sulfate with boiling water in a ratio of 1/10 in an enameled, clay or wooden container.
Residents of the first floors often face such an unpleasant phenomenon as a fungus. In this case, you need to treat the walls with a special antiseptic compound, applying it with a brush and trying to rub into the surface. This will prevent the appearance of the fungus again.
Primer cracks should be primed.
If the defect is insignificant, when closing, you can use the base filler, if the gap is very deep, it should be sealed with a cement-sand mortar. Sometimes pieces of plaster layers move away from the wall along with the lining. In no case should such flaws be ignored. It is necessary to knock down the covering to the base with a hammer, and ground the spalls and plaster it.
The length of the pile on the rollers can vary greatly.
The next stage is the leveling of the walls. You can do this with gypsum cardboard. Then the wall will be ready for putty already for the next day, but drywall takes away excess space, so this option is not suitable for everyone.
The second popular way is plaster leveling. For indoor use, use a gypsum, not a cement mix. It is easy to apply, dries quickly and does not crack. The cement base is suitable for wet rooms, for example, a bathroom. It is better for beginners not to save and use ready-made plasters. They are perfectly met proportions, they are durable and durable. Well protected from the appearance of cracks a fine mesh of fiberglass (fiberglass). It is pasted after the full drying of the plaster and the primer, before the finish putty for painting.
Finish putty on fiberglass should be applied twice, using the technology "on the scuffle". A thin layer of putty is applied with a large spatula, and the excess of the mixture is removed with a tool of a smaller size.
After drying the putty it should be sanded with a fine mesh. Strongly press on the wall can not be to avoid the appearance of scratches. Fresh plaster primed and painted can only be completely dry. The walls are primed in 2-3 layers. It is better to use an acrylic antibacterial primer and leave it to dry for 12 hours.
Principle of coloring
It is quite easy to paint walls with water-based paint. The main thing is to apply the paint evenly. Of great importance is the quality of the paint. It is worth choosing proven manufacturers, you can consult with experts in advance. If the paint has bubbled in the process of work, it is best not to use it, since the defects will remain even after drying. Each painter chooses the proper consistency himself. Some dilute it with a small amount of water, others simply mix the paint well with a mixer directly into the container. A good nozzle mixer is equipped with the right whisk - it has two rows of blades, twisted in the opposite direction, while simultaneously raising the paint from the bottom and lowering it without capturing air. Before applying the paint, the roller must be well impregnated, there should be no interlayers between the pile.
Apply paint at least 2 times. The paint is applied from the top down, evenly distributed over the entire surface. The roller should not reach the ceiling surface by 5-10 cm. This unpainted zone should be painted with a brush. In order for the surface, painted with a brush, to have the identical structure painted with a roller, we need to use the tamping technique. If you make the painting in the usual way from the right to the left, there will be strips on the wall visible to the naked eye. Each strip of paint should go to the newly applied layer no more than 4-8 cm. Repeated layers are applied only after the previous ones have dried completely. If it is necessary to paint a strip about 2-5 cm under the ceiling, you can protect the unpainted surface with a paint tape.
Do not try to save on time and paint and paint the walls in one go. Water-based paint is absorbed differently in a heterogeneous structure, so the appearance of stains can not be avoided anyway.
If you want to paint the wall in the interior in several colors, then the colored strips should also be separated by a paint tape. Before applying it to the already painted area, it should be allowed to dry for 2-3 days. If you paste the tape earlier, when removing it, a part of the paint will come off.
In order to tint the paint in the right color, you can use the computer tinting service. It is very difficult to create the right shade yourself, because the colored water-based paints change color after drying.
