Any suggestions please? I'm painting newly plastered walls I put stainblock on what I thought might be damp patches coming through. I then painted the walls with two coats of watered down emulsion. The stainblock was still showing through. I then painted on a coat of dulux matt emulsion. The stainblock is still showing through and seems to be stopping the paint soaking in. Would I be better using vinyl matt or vinyl silk instead of matt emulsion to get a better purchase and stop the stain block showing through?
Cheers.
