Was reading the Bostik Vapor-Lock pdf.

http://www.bostik-us.com/files/tdsfiles/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?

Here is a better sheet: http://www.bostik-us.com/sites/default/files/Vapor-Lock.pdf

Wood is interesting. It isn't as problematic as vinyl or rubber and note that this product can't be used with vinyl or rubber. Wood can take some vapor and pass it on, like VAT. Mapei has a similar wood adhesive. But you can't use these adhesives on vinyls due to plasticizer migration.

There are great adhesives out there but if you get a failure the adhesive company, when you get down to brass tacks, you have to read the warranty which can be found here: http://www.bostik-us.com/resource-center/
warranties

You can't copy/paste from those waranties... they are locked. But I think it just says that you get Bostik product for Bostic failures.

Tell you what, I will happily sell you miles of every flooring out there, and in the event of a failure I'll give you free glue. Mmmm hm yea I can make those numbers work every day.

I copied this from that link you posted eg 2012 warranties.

Quote:Remedy for Breach of Warranty: In the event of a valid claim under this Limited Warranty, as buyer’s sole remedy, Bostik shall pay the reasonable cost of materials and labor, on a square foot basis, necessary to repair or replace the portion of the original installation that is proven to be defective. IN NO CASE WILL BOSTIK BE LIABLE FOR DIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, ECONOMIC, OR OTHER DAMAGES. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitations may not apply to you.

So, back to my main point, disputing what one person here Tongue is always claiming about having no vapor or functioning vapor retarder under slab.
