Eco-Friendly Flooring Adhesives

Eco-friendly sound reduction polyurethane product is unmatched among flooring adhesivesEpic E-600 is a single component, water free, polyurethane adhesive formulated to bond engineered, solid and bamboo flooring to concrete, plywood and other approved substrates.

Epic E-600 is also designed to have a low permeability to reduce moisture vapor transmission between concrete sub-floors and hardwood or bamboo flooring. Epic E-600 develops a permanent bond and remains flexible to withstand expansion and contraction of the flooring.

Epic E-600 is designed to flow slightly so gaps between trowel ridges will close and create a continuous polyurethane membrane. When applied as directed for subfloor moisture protection, Epic E-600 will prevent damages caused to flooring from moisture in the substrate. Epic E-600 is flexible and will bridge in-plane cracks up to 1/8” wide in concrete.

Do not use Epic E-600 on subfloors with historical or obvious severe moisture problems, or those with a moisture vapor emission rate > 20 lbs per 1000 square feet using the calcium chloride test (ASTM F-1869) or with a relative humidity >90% when tested using in-situ RH probes (ASTM F-2170).

Epic E-600 is also ideal for permanent glue-down installations of plywood subfloors over concrete and for ceramic or stone tile inlays.


Epic E-600 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 chipboard and gypsum concrete that has a minimum 2000 psi mix design for engineered flooring and 2500 psi mix design for solid and bamboo flooring. Epic E-600 is suitable for the installation of flooring over electrical warming and radiant heat systems.

Epic E-600 exceeds the VOC requirements for 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.

Directions for using flooring adhesive.


IMPORTANT: Epic E-600 is designed and intended to reduce moisture vapor emissions originating from concrete subfloors. There are numerous potential sources of moisture that may damage wood flooring. Epic E-600 does not affect moisture from sides, ends or top of the flooring or humid conditions within a structure.


Storage and Shelf Life

Pails of Epic E-600 are purged at the factory to remove moisture and minimize skinning or curing in the container. If there is a layer of cured adhesive simply remove it with a utility knife and discard. The shelf life of unopened containers is 1 year from the date of manufacture. Epic E-600 is available in 4-gallon and 2-gallon pails.
