I'm thinking of ways to remove the concrete cream from my concrete in preparation for epoxy finish. Rather than grinding, I need to use chemicals. Initially was thinking muriatic acid but it's in a basement, although pretty well ventilated and someone told me mixing the standard ratios of acid to water might cause fumes that can be even lethal (that's what he said). They suggested etching solution as a less harmful alternative but that requires a little more hands on approach and attention.
I am interested in the pros and cons of these two competing materials. I have three rooms to clean, totalling about 400 sq ft.
