My painter claims that he is unable to get a uniform finish on my walls in my basement because he says that the drywall texture was not sanded enough so it is "furred". He says that the only way to remedy the problem is to spray enough coats to cover it. The problem I have with his statement is that has used 7 gallons of primer on my 1300 square foot basement (this included priming the unprimed mdf finishwork, but not the doors which were already primed). The walls currently feel like sandpaper. I don't know if he just didn't use enough primer or enough paint or both. Does anyone know if this "furring" really happens? We have a very light hand-troweled finish on the walls (almost smooth wall) and I know that the drywallers sanded it lightly.... Please help!
