Scheme of painting a wall with a roller.Painting a plasterboard wall with water-based paint is the cheapest finishing option. After painting, the surface acquires a matte shade, which hides minor imperfections well. This is how water-based paint differs from other coatings that form a glossy surface, which is extremely demanding on the quality of the preparatory work. In addition, by adding different colors to the white base of water-based paint, you can create any color, but you must remember that this paint becomes somewhat lighter when dry. When preparing it, take this into account and pre-apply the coating to some rough surface to check what the result will be. Having prepared the emulsion for painting, you can begin finishing the wall. Remember that painting is carried out in several thin layers, which must be dried before applying the next one. You need to start painting plasterboard walls from the corners, which are painted with a brush. Also, the space around switches, sockets, distribution boxes, etc. is painted with a brush to a width of 3-4 cm. It is better to paint the wall surface with a roller made of natural materials. Do not stop working until you have completed applying the paint layer to the entire wall area. Surfaces are painted in 2 or 3 layers. Each subsequent layer should be applied perpendicular to the previous one, while the paint of the finishing layer should be stretched by vertical movements of the roller.
Types of paint for walls and ceilings.Using a spray gun for painting can only be recommended to experienced painters who know how to evenly distribute paint over the entire surface. It should be added that replacing brushes and rollers when painting walls is highly undesirable, since new tools may differ from the previous ones in the condition of the bristles or fur coat. As a result, they will leave a different mark. Painting walls should be done in a room protected from drafts, which will ensure uniform drying of the paint. To work with water-based paint, you will need:
- mixer with a nozzle for stirring paint;
- Paint roller with pile medium length;
- flute brush;
- paint bath.
Water-based paint can be used in all rooms where the humidity level does not exceed the normal value.

Therefore, these types of paints are used to paint plasterboard walls in rooms where the humidity level may increase. The painting technology is practically no different from painting walls with a water-based coating, but water-dispersion paints and enamels are applied to the surface in 3 layers. The middle layer is applied somewhat thicker than the primary and finishing layers. Work with paints diluted with chemical solvents should be carried out in well-ventilated areas and with the use of respiratory protection. Return to contents</a>
How to hide irregularities
To the consolation of home craftsmen who stillfailed to achieve a perfectly smooth surface for painting, it can be reported that the defects are well hidden if the walls are painted using the spray method. To do this (after applying the main tone to the surface), use a sprayer or brush dipped in paint of a different color. In front of the wall, hit it on a lath. For spraying, it is better to use at least two tones different from the main one. Having practiced on a rough surface, you will be able to get a very decent result when painting the wall.</ ul>
