Hey everyone, I am really not sure if I should continue with what I have started. I started scraping our passage(hallway) wallpaper off the other day and the plaster underneath is cracked all over especially around the corners of the door frames and where the radiator was there was chunks of it hanging off and some grey coloured filler of some sort covering the brickwork ended up falling off when I was scraping, the hole in the wall is about 30cm wide and about 2-3" deep. Knocking the walls in different places it sounds hollow here and there too. Would it be best for me to give this a shot mys
