Hi. I am planning on tiling my living room wall with reclaimed brick slips that I have already purchased along with the adhesive and mortar. I have just stripped the paper from the wall and a lot of plaster crumbled away. I believe that the house had warm air heating and I am now concerned about whether the plaster is good enough to hold the brick slips without crumbling away. I have attached a picture which shows the hole, the rest of the wall seems ok although sounds a bit hollow in places. What do you guys reckon? Am I ok to tile or would I need to get this checked out? A friend said i may need to knock it back to bare brick and put up new plasterboard. The wall is 2m by 4.5m. Your help and advice is greatly appreciated. Lisa x
