How to choose paint for gypsum board and how to paint walls from this material? There are some nuances to consider here..
So, for painting drywall, you cannot use oil dyes. If the walls have some defects or if there were errors during the putty, then you should not use glossy paint, which will emphasize all the irregularities. Matte paint will be able to hide these small defects..
You can use alkyd enamel, water dispersion or water based paint. It is preferable to use the latter type of paints, and below we will tell you how to paint her drywall walls.
So, you will need water-based paint at the rate of 1 kg per 5 square meters, a paint bath or mesh, a paint mixer, a stepladder, several brushes of different widths, a long-nap roller or spray gun, a work tray, goggles and gloves.
Drywall has good absorption, so it must be prepared before painting, otherwise the paint will lie unevenly and stains will form. To do this, you need to prime the surface, putty all the seams and walls and sand them.
The paint is prepared according to the instructions — mixed or diluted with water. It is recommended to stir the paint with a construction mixer equipped with a special nozzle. First, paint over the joints of the walls and ceiling with a small brush, and then, stepping back 2-5 cm from the ceiling, repeat the procedure, but with the help of a roller. This will mark the boundaries and allow you to paint the walls without touching the ceiling. Next, dip the roller into the paint, remove the excess with a grid and use a W-shaped movement, starting from the top, to paint the wall. If you make two layers of paint, the first is applied horizontally, the second vertically. If there are three layers, then start with vertical movements, apply the second layer horizontally, and the third layer again vertically.
And finally, let’s talk about some of the rules for painting drywall. Use one roller throughout the entire process and do not stop, otherwise the wall pattern will be different due to the different reflective layers of different rollers. Do not turn the roller over and work with only one side of it. If a section of the wall begins to dry out, do not re-paint it. If you break at least one of these rules, then distinct or not very spots may appear on the wall..
