There are several ways to paint the walls, and one of them is the spray method. As practice shows, the technology of painting walls using spraying is the simplest, and the result is more accurate. And from a financial point of view, this method of painting walls is the most economical. Regardless of whether you use enamel or a water emulsion, it is important to follow the correct process technology, and then the result will be at the highest level.
How and what paint to paint the walls, you will receive recommendations on this page.
Painting walls will protect their surfaces from impacts and damage and give them an aesthetic appearance. Before you paint the walls with paint, it should be borne in mind that work should only begin on perfectly smooth surfaces, otherwise the paint will more likely emphasize than hide even small flaws.
What Paint to Paint the Walls: Enamel
Usually (unless otherwise provided by the manufacturer), the technology of painting the walls is a sequential application of 2-3 layers: base, intermediate and surface. They can be made with various types of paints. The composition for the base is well absorbed and also serves as a primer and protection against moisture. Surface paints are more flexible and give the walls the desired shade and texture.
If you do not know which paint is best to paint the walls, then for internal work feel free to use various enamels (oil, alkyd, epoxy, nitrocellulose, etc.). Basically, all these types of paints are toxic (it is advisable to work with them in a well-ventilated room, in a respirator), flammable and less durable, but still continue to be used, because they lie well and dry quickly.
In addition, they allow you to get different in texture walls: matte, rough, semi-gloss, silky, semi-gloss, glossy. Semi-matt and matte surfaces most effectively hide bumps, and paints with a glossy effect look better on perfectly smooth walls and, thanks to their high reflectivity, make the room brighter.
What Paint Is Better to Paint the Walls:
Absolutely even surfaces (for example, a wall lined with drywall) are recommended to be painted with water-dispersion paints (water-based emulsion). Unlike most solvent-based formulations, water-dispersion form a vapor-permeable coating that “breathes”, which has a beneficial effect on the indoor climate. Most often they are used for painting walls, relief wallpapers (wallpaper for painting) and ceilings in dry (bedrooms, living rooms, offices, etc.) and wet ( kitchens, bathrooms, pools, etc.) rooms.
Most of all water-dispersion paints are compositions based on acrylic binders (acrylic paints). They retain color well, do not turn yellow, are resistant to washing, are easy to use, and allow you to create flexible coatings that can “hide” cracks up to 0.5 mm wide.
Water-dispersion paints are produced, as a rule, in white. To obtain the desired shade, a special tinting composition (tint) is added to the paint. Before use, waterborne paint is not diluted with water. How to paint the walls with water-based paint? A water emulsion is applied to the surface to be treated using a roller, brush or spray method (airbrush or spray gun).
How to Paint the Walls With Paint
With proper work on a painted surface, joints of drywall sheets should not be distinguishable. According to the requirements of SNiP 3.04.01-87 “Insulating and finishing coatings”: “In the places of mating surfaces painted in different colors, the curvature of the lines should not exceed 5 mm for simple painting, and 2 mm for improved paint (per 1 m of the surface)”. In addition, the painted surfaces after drying should be uniform, without stripes, spots, smudges, splashes, abrasion (coating). Transmission from underlying layers of paint, peeling, unevenness, wrinkles, visible grains of paint, clots of film, traces of a brush, roller and swab are not allowed. Local corrections that stand out against the general background (except for simple coloring) should not be noticeable at a distance of 3 m from the surface.
How to paint the walls to get a uniformly painted surface? To obtain such a coating, the paint is applied in three layers. Coloring with the first two layers is best done with a fur roller with a long pile, richly dampened with paint. Due to this, the painted surface does not dry out too quickly, which makes it possible to make the layer more even. Finishing is done with a medium-sized paint roller. To wet the rollers with paint, it is advisable to use a flat metal box with longitudinal walls. A sieve (mesh) with cells 10–20 mm in size is installed in the box, along which a roller moistened with paint is drawn to eliminate excess and evenly distribute the composition along the entire perimeter of the roller. You can purchase special cuvette for paint. To eliminate excess and uniform distribution of paint, it has an inclined ribbed surface. For short breaks in operation, the roller should be wrapped in polyethylene to prevent drying of the paint on its “coat”. The next layer is applied after the previous one has completely dried.
The advice on painting walls regarding following a certain sequence is as follows: first, the ceiling and ceiling skirting boards (moldings, cornices) are painted, and only then the walls. The paint is laid first in one direction and in a thicker layer and then shaded in the other. Another recommendation for painting walls: shading is carried out in the direction of the light rays falling from the window. In the event that there are several windows in the room, then shade the paint along its length.
As can be seen in the photo, painting the walls with a border (strip width 50-200 mm) is carried out from the ceiling and cornice. Then it continues along the line outlined by the paint of a different color. Then the curb is diverted and painted directly. The rest of the wall is finished last. At the bottom of the curb, you can draw a panel about 10 mm wide. The choice of colors, of course, depends on the taste and imagination, but it is desirable that the colors of the border and panels are in harmony with the color of the walls.
Tips for Painting Walls by Spraying
Spray painting is considered one of the fastest, most accurate and most economical methods. It is suitable for decorating objects of almost any shape, including those that are difficult to stain with a brush or roller. By spraying it is convenient to paint flat surfaces – doors, walls, decorative screens, furniture – since this method allows you to get a perfectly smooth, thin layer of paint.
To cover small areas, it will be enough for you to purchase an air spray – an airbrush, which is a container equipped with a swap and spray system. More perfect and powerful are electric spray guns. They allow you to achieve high performance and guarantee quality.
When painting the surface of the wall by spraying, the paint must be applied with quick, but smooth movements from side to side, in no case stopping or concentrating the stream at one point. The paint used in this case is less dense than that intended for brush or roller application; therefore, when sprayed with too thick a layer, droplets quickly flow down and violate the uniformity of color.
Now that you know how to properly paint the walls, you can get to work.
