Hello, first post here.
First off, our basement walls (1927 house) are very dry. We live on a hill. However, the walls are quite dirty. In one corner is the chimney cleanout and also the coal door. We shop vac'd most of the old coal chunks off the floor in that area, but the walls are still quite dirty. Photo below. Would these be a good candidate for drylok? I'm worried the walls are so dusty/dirty that the paint won't stick.
I'd like to not only seal against any future drips, but brighten the area up a bit. I would like to do some projects down there, and make it a little more appealing for storage.
Second, if we are a good candidate for drylok, how nasty is this stuff? We can really only open the little coal door for ventilation, the other windows and doors have been sealed up to prevent snow/ice/cold air getting in.
Pics: Most of the basement is like this. Decent shape really:
However the bad parts are over by the coal area... pretty dirty and grubby:
