Hi All,
We have some damp at the bottom of a chimney breast which seems to be due to hydroscopic salts. The wall is plaster (pink) over brick and covered with lining paper and emulsion.
I have been trying to dry out the damp patch with a dehumidifier, fans, hair dryer etc for a week and while it dries out a bit visibly during the day, it comes back overnight. The plaster itself is solid and as the damp is not very widespread I want to try and find the least disruptive solution. Options in order of ease -
1) Paint over the current lining paper with a damp sealing paint and emulsion over - Preferred option - Any suggestions for this?
2) Cover with Wallrock Dampstop lining before lining the wall again and painting with emulsion
3) Hack off the plaster, seal the masonry, replaster and decorate
Thanks
