Painted bathroom a couple of years ago with FOCUS soft sheen emulsion. I have had to make a hole about one foot by one foot to fix a plumbing problem. Have fixed the hole and now want to paint over the filler. Open the pot of paint and its like a lump of stiff jelly. Focus have gone so i cant get the same paint. Can i do anything to liven the paint up to be able to use it? I dont really want to have to paint the whole room, help please!!!!
