How to Prepare Drywall for Painting

The drywall efficiently replaces masonry. Instead of bricks, it consists of plaster plates fixed on galvanized steel structures with own screws. Walls and linings in drywall are suitable for receiving any finishing, including painting and texture. As the plates are made of a plaster-coated kernel on both sides by a duplex card, it is the card that receives the ink. – How to Prepare Drywall for Painting To achieve a better outcome and ensure the quality of the work, you must pay attention to some care.

Check the surface that will receive the painting

  The first thing to do is evaluate the walls that will be painted. Make sure there is no irregularity on the surface before the work begins. The joints between the plates and screws receive a mass and ribbon-specific treatment to leave the surface smooth and uniform, as well as the screws. Failures in this process can cause protrusions or downgrades, and hinder all the work of painting. Therefore, any irregularity should be corrected in advance.

Prepare the surface properly

The second step, and perhaps most importantly, is to perform the correct preparation of the wall or lining. The drywall already offers a smooth and level surface, requiring less work than its equivalent in masonry. Even so, it can display distinctions in color and texture. Furthermore, the dye’s absorption level is different between the surface of the cardboard and the dough, applied in the joints, between the plates, and the head of the screws. The shallowest imperfections are corrected with a simple process: simply apply latex race mass to interiors. Be sure to check that the dough is completely dry before proceeding with the work. To do so, just press the tip of some object (it can be your own fingernail) and observe whether it will be formed any crease or groove. In case that happens, it means the dough isn’t dry yet.

After ensuring the drying, the areas treated in the joints and the head of the screws must be screwed. This prevents scraps of mass and small irregularities, flushing the entire surface of the wall or lining to be painted. Ideal to use a sandpaper money 150 or 180, with a base to keep it flat (you can use a floor bat). But stay tuned: The card should not be screwed! If you want a more sophisticated finishing, the solution is to apply more a coat of background or dough over the entire surface of the drywall. Then sand the walls with a sandpaper money 220 or 280, always with a base. After this part of the process is completed, you need to clean the dust that accumulates on the surface.


In addition to preparing the drywall in the correct way, it is also necessary to prepare the ink. Don’t forget to stir all the products before using. This leaves the ink with the homogeneous texture, ensuring that its contents are perfectly uniform at the time of the application. To dilute the product, observe the specifications of each manufacturer and follow what is recommended in the packaging.

Understand quality levels

The painting in drywall complies with three levels of quality: minimal, intermediate and superior, which should be chosen according to the need for your environment. For the minimum level, the application of the diluted ink is made to 50% as a background in two or three hands. It presents a good finishing with a low cost, and small imperfections are acceptable. It is ideal for popular residential and commercial environments, deposits. At the intermediate level, a diluted pigmented fund should be applied first. Then two or three coats of standard ink.

The result is a quality finish, without visible imperfections, except under the incidence of intense and shallow light. The upper level accepts no imperfection, even when subjected to strong light and thorough examination. In addition to the diluted pigmented fund, the application of one or two grader dough must be made. The surface must be sanded by the sandpaper dough 220/280, with a base. Only then applies to premium ink in two or three hands.
