Am doing some re-tiling, and in the process of ripping the old tiles off the
existing plasterboard. Because I have driven a scraper behind to break the
tiles away, this has actually gone OK with minimum damage - limited to
strips and patches of the think paper of the plasterboard torn away, and no
damage to the plaster beneath.
Whilst it looks a mess, there is a fair percentage of the original surface
left where each new tile would be so I was thinking about sanding flat the
sound areas where adhesive remains and then skimming over the damaged areas.
Whatever I use will need to bind to the fuzzy paper surface. Assuming this
is what most people do - what is best, a filler or a finishing plaster? The
skim would be very thin so I'm thinking a filler may be better......
