Hi,
Started a bathroom renovation a few weeks back and noticed some tiles on one of the external walls was bowing so decided to investigate as the tiles needed to come off anyway.
The old Newton lath circa 1970s (Which I was told on here) has perished but didn't seem to be any damp coming through anywhere.
I've taken off the undercoat and plaster on the external walls and replaced with permagard/dab/skim.
1st question...
How long does it usually take for dabs and skim to dry out on permagard. As it was nearly a week and there were still patches and especially around the toilet waste which was as dark as the day after I skimmed them.
2nd question...
There was a few bricks and joints not in great condition around the toilet waste, I used expanding foam to fill and the cut the parmagard around it and then used the role of joint tape they provide to patch in the gaps. Could the foam hold damp and cause a severe bridge? As now 9 days later it still looks like this.
.........
I have taken 400mm off the dabbed boards on the two external walls and have noticed these droplets.
If I chase out the floor along the line of the permagard and sand cement around the toilet waste properly. Would tanking the walls and floor solve this problem?
