Adhesive/Vapor Retarding Membranes.

Was reading the Bostik Vapor-Lock pdf.

Quote:Quote Bostik "For substrates that have an MVER of greater than 15 lbs or an RH
greater than 85% or for substrates where a vapor retarder is not
used or is not functioning below slab, use Bostik Ultra-Set® Single-
Step™or Bostik MVP4/Bostik Adhesive System."

Hmmm, what-a-da-yas-think?
