I own a split-entry home where the foundation block is exposed about 4 feet above ground on either side of the house. On one side I have started notice a significant amount of paint lifting and flaking away. Last night as I was preparing the surface for Dry-Lok I noticed some spawling as well. some areas are real superficial, but some spots crumble away almost .25 to .5 inches deep. I know there are several products that claim to fix this problem, but what is the best solution? I want to repair the block now while it is dry and warm out. Also, Is it safe to use a pressure washer to remove all the loose paint and cement or do I run the risk of creating a larger problem? The block is typical concrete cinder blocks. The house was built in '79 and I have lived there for just over 2 years, so I really don't know how long the block has been this way. I only noticed it due to the paint chipping away. I should also not that I do not have a water problem in the basement, so perhaps this is indicating that the problem is on the surface and I'm catching it early. Please advise before I proceed.
Thank you
