Forum Title: Bostik Vapor lock or Mapei UltraBond Eco980?
Bostik Vapor lock or Mapei UltraBond Eco980? Which is better for glue down engineered wood installation? I need both vapor/moisture and adhesive combo.

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. I will not use the Mapei, but anything Bostik has always worked for me.
