Recently purchased 1900's Victorian mid terrace. 9inch solid brick external walls. Suspended timber floor at the front, quarry tile and Earth at the back.
The problem I have is that following a reskim over what appeared to be a gypsum finish to the internal wall between the front and back rooms using a multi finish (I think), I now have this small section of wall which refuses to dry out! In actual fact a few days after it was plastered the quarry tiles in this corner were so wet I decided to replace the floor with a new concrete floor to see if this helped with the issue. I now have a dry floor and a wet wall... Could this be condensation down to the fact we are not living in it and the place is not heated or do I need to knock this off and apply sand and cement?
