Damp walls, besides being an aesthetic problem that affects the whole room, can also lead to health problems and adversely affect the comfort and welfare of the inhabitants of the home. You should eliminate the problem as quickly as possible and repair the damage. In the following OneHowTo.com article we show you some simple tips so you know how to paint a damp wall. This method has excellent results and you won't have to worry about the appearance of stains on the walls.
Before you start painting the wall, you need to find and determine the cause of dampness. There are different types of damp (Filtration, condensation and capillarity) so the origin may be due to several factors:
- If damp is filtered, as can be for exhaust pipes, it is imperative to repair the fault to prevent damp. Thus, the problem is solved and when the wall is completely dry, it is ready to be painted.
- At other times, damp is generated due to water intrusion from the outside and the best method in this case is waterproof the wall using bituminous paint, which is ideal for creating a protective barrier against damp and prevent infiltrations.
However, in many cases and most often a big wet spot in the wall appears, due to condensation of water vapour. This usually happens in cold rooms, with little sun and a high degree of humidity. In this case, it is essential that you remove the stain so that you can later paint the wall and get excellent results. We explain how below.
First, check if the wet spot is dry or not. When the stain is dry and has no rust, simply paint the wall with a good anti-damp paint which can be purchased at any specialized maintenance and home renovation store.
If instead the wet spot has efflorescence or mould, you need to remove them. To do this you have two options: use a diluted bleach solution and apply it to the stain with a cloth or soft brush, or apply hydrogen peroxide with a rag to remove fungi. When finished, rinse and leave the wall to dry so that the stain dries.
To continue the task of painting a damp wall, it is best to then apply a chlorinated rubber paint to the stain which is perfect for permanently eradicating the problems of damp on the walls. It is a type of paint that is often used to paint pools due to its great and powerful fungicide power. Once you have applied the paint on the stain, leave it to dry for 15-20 minutes after this time, you can proceed to paint the wall with standard plastic paint.
