I've knocked the wall tiles off easily enough - a strip of them above
where the old kitchen units were. The adhesive left on the walls is
your usual white stuff. Is there anything I an apply to it that will
cause it to lose its adhesion, or dissolve it, so I don't have to
scrape it all off? I don't mind the work in scraping it off, but I'll
probably leave marks in the plaster, and I want to paint the wall
afterwards.

Regards
Richard
