My walls are a vinyl covered drywall and I want to apply drywall mud to change the texture and paint it. A friend did this to a regular paneled wall. Will it work? My husband is afraid it will peel and/or crack because of the vinyl covering. Thanks for all help!
It is not difficult to resurface your vinyl walls. At the seams, tape and mud like regular drywall (I cut about 2" of the vinyl off each side of the seam, leaving the paper backing for mud adhesion). Then prime the walls with Kilz or a primer like that. After priming, if you truly want to smooth out the wall to match the seam, skim the whole wall with a very thin layer of mud. Sand, re-prime and paint. I have tried this in various mobile homes with great success.
