I have striped wallpaper off my wall. to my surprise the wall is patchy, rough, and flaky. e time i rub my hands on the wall or sand the wall, small grins of sand rub off on the floor. the solution to the problem will be to re-plaster or re-skim but i don’t have the money and i don’t have the expertise (no how) to plaster a wall. is there an inexpensive way for a diy novice to solve the problem?

It sounds to me this wallrequires to be sealed witha diluted pva solution available from most diy shops,coat the wall with the solution let it dry and then fill any major blemishes with a fine surface polyfilla, then re paper or paint as requiredregardssteve
