Both are almost identical, the more important decision would be whether or not you need a vapor barrier glue ... this will be determined based on whether or not you are on a slab or subfloor.

Redbud is correct. The two brands have lines that are often times interchangeable. Some people use Mapei because they have easy access to the line. Others use Bostik for the same reason.

Your conditions of the subfloor will direct you towards the correct version of Mapei or Bostik.

I have concrete subfloor, so would I go with Bostik Best Adhesive for example?

Our company has been using Bositk's EFA glue for all engineered wood installs, slab and pier and beam, for nearly 15 yrs. Wouldn't recommend any other glue.

Mochaheart, Bostik best is for solid wood. You will want to use EFA from Bostik. EFA=Engineered Flooring Adhesive.

What's the moisture content of the concrete? What tests have you done to confirm which adhesive will work? How many different tests did your flooring professional perform to confirm the RH of the slab? Did they HAND YOU the test results and go over them with you?

Concrete is fascinating...and considered an art form rather than a science. Getting to grips with concrete takes a lifetime. And most general installers have very little info/training with concrete. Which means DIY homeowners have very little understanding of concrete as you can get.

A DIY glue down installation over concrete is possible...but fraught with danger. It is easier to ruin than it is to get right.
