This flooring adhesive with moisture and sound barrier provides a moisture barrier to protect your floor from any moisture transmitted from a sub-floor, as well as filling in any cracks or ridges in the concrete. In order to achieve the proper vapor barrier, you must use a 1/4" x 1/4" V-Notch trowel.


It has an ultra low VOC content and is low odor, so you can relax knowing that you are using the safest possible adhesive product. It is also extremely elastic so it allows the boards to expand or contract without having a detrimental effect.


This adhesive really is the all in one solution to installing a perfect, long-lasting floor. But, what happens if you accidentally drip some on your beautiful new floors? Get yourself a tub or two of these handy-dandy adhesive remover wipes and avoid the headache!


  • Retards Moisture Vapor Transmission from Concrete Slabs
  • Crack Bridging
  • Low Odor
  • Excellent Green Grab
  • Does Not Contain Water

This is a single component, water free, polyurethane adhesive formulated to bond engineered, solid and bamboo flooring to concrete, plywood and other approved substrates. It is also designed to have a low permeability to reduce moisture vapor transmission between concrete sub-floors and hardwood or Bamboo flooring. This product develops a permanent bond and remains flexible to withstand expansion and contraction of the flooring.

It is designed to flow slightly so that gaps between trowel ridges will close and create a continuous polyurethane membrane. When applied as directed for subfloor moisture protection it will prevent damages caused to flooring from moisture in the substrate. Is flexible and will bridge in-plane cracks up to 1/8 in wide in concrete. 


The manufacturer recommends allowing the adhesive to cure for 12-15 hours before walking on it, and 24 hours before moving heavy furniture back into place.

It is also ideal for permanent glue-down installations of plywood subfloors over concrete and for ceramic or stone tile inlays. It may be used over cement patches, cement self-leveling underlayments or screeds; properly prepared existing ceramic tile, well bonded sheet vinyl or VCT tiles existing cement terrazzo, underlayment grade chip board and gypsum concrete that has a minimum 2000 psi mix design for engineered flooring and 2500 psi mix design for solid and bamboo flooring. It is suitable for the installation of flooring over electrical warming and radiant heat systems.

This adhesive meets the most strict infoor air quality and VOC requirements set by the Southern Coast Air Quality Management District (SCAQMD) for wood flooring adhesives and therefore may contribute to the qualification of a project for LEED NC V3 certification for Indoor Environmental Air Quality credits for low emitting materials ED 4.1 Adhesives and Sealants.

Do not use this product on subfloors with historical or obvious severe moisture problems; or those with a moisture vapor emission rate >15lbs per 1000 square feet using the calcium chloride test (ASTM F-1869) or with a relative humidity >85% when tested using in-situ RH probes (ASTM F-2170).


A NOTE ABOUT VOC'S.  Our adhesives do not have any ingredients that are defined as volatile organic chemicals “VOC’s”  as part of the formulas.  VOC is a regulatory description for “solvent” which evaporates into the air and is considered an air pollutant.  These formulas contain none, so we refer to them as zero-voc. We can calculate "potential" trace VOC values based on the vapor pressure of the individual raw materials used in the formula. Anything with a vapor pressure greater than 2 mmHG at 25C is considered a VOC for these calculations. The results are as follows:


Bilders Ultimate has a VOC of  less than or equal to  0.77g/L 


These trace values reflect the highest possible VOC content- prior to processing and evacuating at elevated temperatures.
