by: NA Question: Say this happens: You scrape the peeling, black with mildew paint from your basement walls, only to have some mortar crumble out. How do you replace the mortar and waterproof it simultaneously? With ThoroughSeal? You've heard it's the best product. Can one put it over the plaster on your concrete block walls?
Does anything special need to be done where the floor meets the walls? Is a continuous crack all the way around the house anything to worry about? Diagnosis, Analysis, Solutions and other Feedback: The mortar joints should be filled or repainted by a mason. If you are having a real water problem we're so sure ThoroSeal is the answer. First, any type of coating is only as good as the base it's adhered to. This is also negative side waterproofing which will allow water to stay in the blocks. The floor/wall joint is a natural seam created by the construction and it's the number one source for water entry into the basement floor. There is no guaranteed way to seal this joint. Have a local reputable basement waterproofer look at your basement if you are having a water problem. If there is no real water problem then sealing may help with moisture or dampness. |
