I used this to cover my son's walls which had polystyrene wall cladding on and lining paper.There were holes in the lining paper and this covered them brilliantly.It goes up so easily and there's no match difference so no waste.I painted the paper and it looks so smooth and firm,you can't tell there's cladding underneath at all.Really impressed with it.My partner has also used it to cover his imperfect walls.
