Suddenly, the plaster bowed outwards and cracked. (Brown plaster on sand/cement render underneath.)
Question: The area in question (10 ins x 6 ins) is tucked away in a remote corner. Given that I intend to wallpaper over it, is it acceptable to slap some filler on the crack, ignore the bowing and hollow sound and just forget about it (until next time)? Or do I need to dig out and replace the entire patch. If so, is it acceptable to use filler/polyfilla stuff? I haven't done any plastering before. It all sounds a bit technical! Bruce
