i a going to attempt to install br111 solid plank over a concrete slab approx 10 years old. I have poured leveling compound on just about the entire floor. I have some parabond 870 ultra-thane adheasive that was recommended to me by a localstore. they said it has a builtin moisture barrier but i cannot confirm that on parabonds website. i want to put down umbiii from parabond or the bostik mvp4 product. I am wondering if this glue and moisture barrier will work together???

The Parabond is not a moisture barrier.


Use the moisture blocker and adhesive, as a system, from the same manufacturer.

But most importantly, solid over concrete, is a VERY BIG RISK, no matter who says you can do it.
