Drywall Patching Question
Thanks in advance
Thanks for question.
I have asked my painting contractor friend Mark from O’LALOR PAINTING COMPANY to respond to your question.
Hiding Drywall Patch Edges
Yes compound can be applied over a painted surface but it is very important to scuff the area and wash it with TSP so that maximum adhesion can take place.
If you don’t properly prepare it beforehand it will lift off in sheets within a couple of years.
The washing phase is important for two reasons. First, the TSP cuts the latex sheen and second it removes any ambient dust that would create a barrier between the wall compound and the painted surface.
Good Luck, Mark O’
