Got a bit of a DIY project going at the moment. All was going great until I decided to sand the wall down. The wall in question is plasterboard and the previous owner must have just chucked a tin of satin emulsion over it for coverage. The are raised streaks all over, plus the removal of various shelves meant some filler. I decided to get the sander out with a 120 grit paper but thats when the problem started. In places the paint is so thick that it gets hot, melts and then reforms in to a rock solid patch that only remelts and reforms each time I try to remove it. I have thought about replacing the plasterboard but the wife says NO! Shes right of coarse, the room is complete all but for this wall.
I was wondering if changing the grit size of the paper to maybe 80 would help. My theory on that is that it will hopefully remove the paint quicker and not have time to heat up :oops: . If not could anyone please offer some alternative methods.
Many Thanks In Advance
