Dining room 15x20 addition, block on slab, circa ~1960 backfilled about 4’. Impossible to remove backfill & seal exterior due to huge slope. Furring strips w/Sheetrock & flooring was ruined due to water penetration from waterseal failure. Appeared to be Drylock. Wirebrushed & cleaned interior block. Did the recommended adhesion test. It failed. Primed the surface & did the test again, all good. Primed the wall & applied 4 coats of Ames Block & Wall. The material went on great & penetrated & sealed the pores in the block extremely well. Very good coverage per gallon. I was pleasantly surprised. As I don’t want any further issues, I did the 4 coats. Basically the wall now has an integral contiguous rubber barrier to fend off any permeation of water. After seeing this product I have a high degree of confidence that I will not have any issues going forward, none. I intend on purchasing another 5gal jug with which to seal my basement. I would not hesitate to recommend Ames Block & Wall.
It’s great stuff paint it on or roll it even spray it make sure surfaces are clean and when applying do coats the thin let dry and do it again is best way to make it work
Really good stuff worth the money I've used it on various projects an never disappointed me.. Awesome
