The pic quality isnt brilliant. I have been stripping the wall paper off the kitchen wall and the top layer of plaster has come off revealing the plaster underneath which is also falling apart, its like a mixture of sand and stones. What plaster do i use to fix this? Thistle coat multi finish? Sorry i havnt got much experience in plastering cue the laughs Also the last pic is taken of the only bit of plaster situated abouve the gas cooker which doesnt come away from the wall. There is a hole just above it reveling a pipe or cable.
