My problem is this, having a wall with traces of mold, I treated with DIP treatment wet plasters, only downside, the walls were already painted !! And the painting that I wanted to apply has no adhesion, what is the solution to my problem?

Whatever its surface, a damp wall is a bad base for renovations. You must first look for the cause of the moisture and eliminate it. Once the problem is solved, scrape all the affected parts of the wall with a stiff brush, sand to remove the various coatings. Then only, and after drying by heating or dehumidifier you can pass a water repellent product in two layers. After complete drying you can apply a new plaster and paint it.

Consult our sheet on WET WALL TREATMENT which is on our site to help you in your work.
