A frozen/bursting outside pipe (now fixed) led to some minor water damage in the interior finished coat of a basement exterior wall. This is in an 80 year old house. The wall is a coat of finished plaster over a coat of gray first-coat (plaster as well I guess, or perhaps mortar?) over brick. The affected area is very small -- 4 feet x 4 feet. Please critique my plan: 1. Remove any top coat plaster and any first coat gray plaster/mortar that might have been compromised by the water, reaching to bare brick as needed in some areas. I won't be overly aggressive -- I will just remove what needs to be remove and leave what is in good shape 2. A coat of drylok in the bare brick area (and even in the exposed first gray coat areas) 3. A coat of the first-coat mortar in the bare brick areas as needed. 4. A coat of easy sand 20 over the first gray coat. Sanding as needed. 5. zinsser 123 primer 6. interior bm paint. The big question that I have is: after removing the compromised material (part 1) how long do I have to wait until any remaining moisture dries before applying the drylok and proceeding? The leak was fixed 3 months ago, so no new water has been present, but I didn't remove the compromised material, which might have trapped moisture. Is 2 week after removal of the compromised material reasonable before drylok? Thanks.

hi, I'm installing a new plywood ceiling. the decorator has tried to seal and paint the gaps between the boards several times, the next day the putty has leaked down to form ridges all around the ceiling. any suggestions? Started with regular household putty, that leaked down and formed the ridges, yesterday he tried car body filler. This has dried and separated from the wood.
