Hi there
Iv'e just stripped our walls this weekend to see what state they are in ,but it's a bit of a mixed bag.Some of the original plaster is cracked but solid ,in other areas its blown from the wall, plus somebody else has tryed to fill in the cracks and holes but have made a pigs ear of it.
(1)I have thought of knocking off the old plaster in the bad areas then fillin and skimmin the walls.but i want to try and keep the dust aspect as low as possible .
(2) is to plaster board over the old stuff(ie) dot and dab then skim.But would the boards come away with the old plaster.
any advice would be welcome thanks.
