Masonry waterproofer – vapor barrier?
Weekend worrier here. I’m working on the conversion of a slab-on-grade shed into occupied space. It will have 1/2″ treated ply laid on the slab, and then floating floor.
The floor surface of the slab is 4″ – 12″ above a slanted grade.
UGL sells a product that their advertising swears will waterproof masonry. Will such a product serve as a vapor barrier, or should I put down a plastic vapor barrier?
