Hi,
I want to remove all wallpaper from the house and replace with paint. Unfortunately after stripping one of the bedroom walls I found out that the original builders just slapped wallpaper directly onto the plasterboard without a skim first. The wallpaper was subsequently removed in later years and replaced with newer wallpaper.
What I'm finding is that after using a steamer the backing of one of the wallpapers is still present. If I damp an area with warm water and try scrapping the backing away I end up removing the plasterboard lining (circled). I've started so I may as well finish but are there any good options besides getting the walls skimmed or removing all the backing/glue by hand (tortuous!)?
I was thinking of a shellac based primer on top of the backing, with plasterboard tape for the seams and some polyfilla on this and any rougher areas?
Thanks.
