Still trying to understand why you don’t care about trapping vapor under a vapor barrier
Still trying to understand why you don’t care about trapping vapor under a vapor barrier if there is vapor constantly pushing up from the earth. Also interested in good sealant.
I am having trouble nailing down the answers to two questions: first I asked about creating a greenhouse effect by putting a layer of poly over the slab on grade basement floor. I have an imperfect vapor barrier below the slab but there are seams and strips with missing plastic. So in short, if vapor is constantly pushing up why arent you concerned about trapping it over the slab, creating a mold inducive environment?
Second, I would like to use a sealant on the concrete floor and walls. Ive learned of two: Enduro Seal which supposedly infiltrates the concrete and fills in the capillaries to block moisture pushing upward to the slab surface. They claim to have no offgassing. I wonder what your team thinks of such a product for an insulated living space?
