Tip 1: Check for the cause of the damp wall

The very first thing to do whenever you’re looking for a way to deal with dampness on your wall is to check and work out what’s causing it. There are various types of damp that you’ll come across. These include condensation, filtration or capillarity. This means that several factors could have led to the dampness you see. Filtration dampness is caused by exhaust pipes. Therefore, it’s imperative to ensure the pipes are repaired to prevent dampness. Once the wall is dry, it can then be painted.

Another way through which dampness of a wall can result is by the intrusion of water from outside the house. The best treatment in such a case is through the use of bituminous paint to make the wall waterproof. It serves as a protective barrier for dampness and prevents filtration from taking place.

 

Tip 2: Check the Humidity of the room

Often, because of condensation of water vapour, a huge wet spot appears on the wall. This normally happens in rooms with a high degree of humidity, with little sun or which are very cold. Therefore, you should check the level of humidity in your room. To deal with this, you should first remove the stain in anticipation for later painting.

Tip 3: Use an Anti-damp paint to paint over

The first thing to do with the spot on the wall is to check whether it’s wet or dry. In case of a dry stain and doesn’t have any rust, you can simply use an anti-damp paint to paint the wall. This paint can be purchased from any home renovation and specialized maintenance store.

Tip 4: Check for Mould

In case the spot contains mould or efflorescence, you should remove them first. There are two different ways to do this. The first is to use a soft brush or cloth to apply a diluted bleach solution to the area. The alternative method is to remove fungi with a rag soaked in hydrogen peroxide. Once you’re finished, rinse the wall and leave it to allow the stain to dry.

 

Tip 5: Use a Chlorinated rubber

In the task of painting damp walls, the next best thing to do is to apply chlorinated rubber paint to the stained spot. This helps to ensure that the problem of dampness on the wall is dealt with permanently. Upon completing the application of the paint, ensure you leave it for between 15-20 minutes to dry. After this duration, you can then proceed to use a standard plastic paint to paint the wall.
