what is the best way to fill holes and dents in plaster ready for it to be wallpapered over some of the holes and dents are over half an inch in depth, should i do it with poly filler in layers and also some big pieces of skim has come off about 12 inches square and about 3mm in depth can i use the poly filler to patch this as well or can i use something else, thanks,
someone told me i can use coving adhesive in place of filler, is this also correct or should i stick to poly filler.
