Cementing Basement Walls

[Clodfobble]

Yeah, I don't understand what's going on in the pictures there either. Is that what you painted it to look like? Or what it looks like after you tried to strip some of it off with paint remover?

You can't paint someone else's house, dude. If you did that to my basement, I'd be making you pay to fix it too.

Edit to add: Regardless of how it got that way, I think a far better solution than cementing over it is to just give it a new uniform coat of paint. Get an outdoor paint (the kind meant for cement/industrial floors) in a shade of cement gray, and do it right.
