Bamboo and Exotic Wood Floors - Moisture barrier bamboo

I recently put bamboo on my upstairs floor, nails to subfloor, and everything looks great. I just started my pool (billiards) room downstairs. The room is concrete slab and I layed the first set of rows using an adhesive from Home Depot called Roberts 1408. I didn't put down a moisture barrier. The room is at ground level and I live in Phoenix. I'm assuming that I shouldn't have moisture issues. Bad assumption? If so what should I use as a moisture barrier? I was told there is a product that is like a sealer that I can then put the adhesive on top of.

Hi James,

This is straight from a bamboo manufacturer:
Concrete subfloors must be fully cured, at least 60 days old, and should have minimum 6-mil polyfilm between concrete and
ground. Subfloor should be flat and level within 3/16” per 10’ radius. If necessary grind high spots down and level low spots with
Ardex® K-15 Portland Leveling Compound.
All concrete should be tested for moisture using a Calcium Chloride Test, and the result must not exceed 3 lbs. (2 lbs. when
installing over radiant heat). Ceramic tile, resilient tile and sheet vinyl must be well-bonded to subfloor, in good condition, clean
and level. Do not sand existing vinyl floors, as they may contain asbestos.
If gluing down on concrete (even if you believe it is dry) which is on or below grade, it is highly recommended to install sheet
vinyl first and then glue the wood flooring on top of the vinyl, as this provides an effective permanent moisture barrier. Another
alternative to sheet vinyl is to use the Bostik® or Taylor® Moisture Barrier Systems, which are warranted by their manufacturers.

Thanks for the quick response.
