Help! Have filled several holes and cracks in my bathroom wall (fairly badly, I admit), but assumed I could just sand the edges flat after. However, the filler has set so hard, that when I try to sand, it simply removes the surrounding plaster, and the filler isn't budging!
Does anybody know of anything I can do - what is the best thing to use to sand, etc?
