I’ve been making a mess stripping wallpaper. The wallpaper had been painted with a gloss or vinyl paint which defeated the steamer. I ended up using a 5 inch bladed scraper to take the top layer of the wallpaper off, then the steamer and a paint scraper to remove the remains. The whole room should be stripped in 3 days.
The steamer can also remove the textured paint underneath, but that is slow work and a scabbler and another skim coat will be quicker (there is no asbestos – it’s a thin emulsion textured coating).
Guess what – I found some damp! The impermeable paint had trapped water coming through from underfloor in the adjacent rooms which have a higher ground level. It seems to be drying out now the wallpaper has been removed so a nice breathable clay paint should allow the wall to find a new equilibrium and avoid damp without any real effort on my part.
