Can you paint or wallpaper over vinyl walls in manufactured homes?
I own an older double wide in NJ and decided to paint over one of our bathrooms since the floral pattern might have looked good 20 years ago, but has not for at least a decade. I found that if you thoroughly clean the walls with TSP or similar after lightly scuffing the surface with a scothbrite pad and then using a quality primer that is made for this purpose (read the can), then painting with a good quality paint you should have not problems. I have had good luck with a Glidden primer and Behr paint. I painted about two years ago and have had no problems with peeling or cracking.
