PSA: That $250 'waterproof' basement sealer from Home Depot ruined my floor
I spent $250 on that thick rubberized sealer for my Cleveland basement after a wet spring, and it peeled off in sheets within 6 months. Now I'm looking at $1,200 to sand and redo it properly. Anyone else get burned by those big box store sealers?

Oh man, that stuff is garbage. I learned the same lesson in my garage - those rubberized sealers don't bond right on concrete that's even slightly damp or dirty underneath. You gotta go with a two-part epoxy or that Drylok paint that's meant for masonry, but even then you need to etch the floor first.

Bought into the same hype a few years back. Spent a whole weekend scrubbing my garage floor only to have it flake off in sheets a month later. Ended up grinding the whole thing down to bare concrete and using that two-part Rust-Oleum epoxy kit, but even that took a full etch and waiting three days for it to cure before I could park on it. Never cutting corners on prep again.

Big box specials like that are a total trap, I speak from experience. @ivanross is right about the prep work - I thought I could skip etching because I was in a hurry and my floor looked clean, but it peeled like old sunburn. Did you end up going with the two-part stuff for the redo or trying something else?
