For the new paint on your walls to be perfect and look good for a long time, you must prepare the surface beforehand. 

Hiring professional Oahu pro painters helps a great deal in producing this perfect result. However, in this post, we will give you some tips to prepare your walls before painting, which will be useful if they are new or already have a previous coat of paint.

  1. Remove The Remains Of Paint

The most common when painting a wall is that it has a previous coat of paint. The first step is to remove all the chips with a spatula, always taking great care not to damage the wall’s finish.

As we do not want the new layer of paint to leave the holes marked when the roller passes, we will use fine-grained sandpaper to even the edges and smoothen the unevenness. 

  1. Beware Of Mold

Mold can easily appear on walls that are in contact with humidity. It can occur in bedrooms or living room if we live in houses with a lot of humidity. If the mold is not removed correctly, it will come out again on the new layer of paint, spoiling the finish and damaging our health.

To eliminate mold, we must clean the entire surface with a cloth impregnated with bleach, vinegar, or bleach. Before painting, we will let the surface dry very well, then we can repeat the process two or three times to ensure complete disinfection.

  1. Repair Wall Damage

Small nicks, scratches, and cracks do not disappear just with a coat of paint. If we use satin paint, they will stand out even more. Ideally, they should be completely repaired before applying the new coat of paint.

You can do this by applying wall putty on them, choosing interior or exterior versions depending on the surface to be painted. The best tool to apply it is a soft spatula, plastic ones are recommended. Once the crack or slit is covered, we remove the rest of the putty, let it dry, and sand to eliminate the edges.

  1. Clean The Wall Properly

If we want the paint to adhere completely to the wall, it must be very clean. On the other hand, when the wall has previous paint coats, it is convenient to wash them and use a fine cement plaster.

With sanding, we remove the grain of the sand used for plastering and create a suitable surface for the paint to adhere properly. On plasterboard walls, the surface is already suitable for painting.

Whether we have sanded or not, the last step will be to clean the entire surface with a fine bristle brush and a dry cotton cloth.
