Vapor Barrier for Existing Slab
I’m seeking product recommendations for topically applied above slab concrete vapor barrier for old existing slabs, achieving a documentable .06 Class I vapor barrier per ASTM E96 . I’m stuck with the .06 requirement, and can’t make any form of compromise there. And I’m stuck with the old slabs. California Climate Zone 3
Thanks to Martin, I’m aware that:
What would you use on top of such slabs?
How would flooring choice affect the barrier choice?
The photo is one of the slabs that needs the treatment.
