E-600 Vapor Retarder Polyurethane Adhesive

Sound Reduction Adhesive Features

Flooring Adhesive Formulation Technical Data

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 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. 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 Use of Flooring Adhesive Formulation

Review the technical data sheet prior to starting the installation. Follow applicable industry guidelines and manufacturer’s instructions for design, layout, acclimation and expansion space around the perimeter and within the field of flooring.

Vapor Retarder Surface Preparation

Improper surface preparation is the most common reason for failure of glue down wood flooring. Surface preparation is especially critical when installing less stable products such as solid hardwood or bamboo flooring.

Surfaces must be clean, dry and flat to within 3/16” in 10’; free of voids, loose materials, paint, varnish, adhesive residues, sealers, oil, grease, plaster and gypsum finishing compounds. Asphaltic “cut-back” adhesive residues should be completely removed prior to the installation of solid or bamboo flooring or if there is concern/history with elevated moisture content in concrete.

CAUTION: Black mastic or cut-back adhesive residues may contain asbestos. Follow applicable state and federal regulations for handling asbestos containing materials.

Dimensionally stable, engineered flooring may be installed over on and above grade concrete that has an asphaltic or “cut-back” adhesive residue after preparation. Such a residue must be completely removed from the surface and only exist as a black stain on the concrete. Do not install solid or bamboo flooring over cut-back adhesive residue; and do not install over cut-back adhesive residue below grade or if there is or ever has been a moisture concern with slab.

Concrete substrates should not be smooth or reflective. Suitable concrete will have a minimum CSP 3 surface profile, which is similar in roughness to a light broom finish.

Remove contamination and create a surface profile by diamond grinding, shot blasting or scarifying. The use of floor sanding equipment may polish contaminates into the concrete. Be sure the resulting concrete is porous and clean.

Areas that require patching or leveling should be treated with Portland cement based materials. Do not use gypsum patching or leveling products for substrate preparation.

If installing over existing sheet vinyl or VCT, all waxes and sealers must be completely removed and the existing flooring must be well bonded. Installations over existing sheet vinyl or VCT are limited to dimensionally stable engineered wood flooring only.

If installing over existing ceramic tile, natural stone or terrazzo, all waxes and sealers must be completely removed. Highly reflective tile, stone or terrazzo should be lightly abraded with a sanding disk to improve adhesion.

Bamboo and Wood Flooring Installation

Job-site conditions effect the handling and curing of this adhesive. Cold conditions make adhesives more difficult to spread. High relative humidity accelerates cure/hardening. Dry conditions slow cure/hardening.

Vapor retardant and sound reducing polyurethane adhesiveInstallation begins with a starter row secured to the subfloor. The starter row provides a stationary point to push against so the flooring doesn’t move during the installation process. Once the starter row is complete, apply the adhesive to the substrate using the appropriate notched trowel. Refer to the trowel coverage chart on the back page.

Install the flooring immediately into the adhesive. Avoid getting adhesive on pre-finished wood flooring. Immediately remove any adhesive from the surface of the flooring using a towel or rag dampened with mineral spirits paint thinner. Take care to remove all adhesive from the surface prior to curing/hardening. Cured adhesive is difficult to remove from pre-finished flooring.

After a few rows have been installed, tape the boards together using 3M #2080 Blue tape. The tape will prevent the flooring from sliding. Flooring that is not flat should be weighted to ensure proper adhesive transfer between the flooring and the sub-floor.

To remove cured adhesive from prefinished flooring, use Sentinel 747 adhesive remover. Apply the adhesive remover to the affected area with a non-abrasive towel and allow to sit for 5-10 minutes to soften the adhesive. Then buff the adhesive off with the non-abrasive towel. Be sure to clean any remaining adhesive remover from the floor.

Glue-Down Installation of Plywood Subfloor

Use 19/32” (5/8”) or better plywood subfloor panels cut into 2’ X 8’ or 4’ X 4’ sections. Score the backside of the panels every 12” in both directions. Apply Epic E-600 to the subfloor using a ¼” X ¼” square or V notch trowel and lay the sections of subfloor into the adhesive in a staggered joint pattern with 1/8” space between the panels and ¾” space around the perimeter and vertical obstructions.

Limitations

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. 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.

Suggested Notched Trowels

Larger notched trowels are used for thicker flooring products. Additional adhesive will fill voids and minimize hollow spots. For adhesive and moisture protection, trowels with a saw tooth configuration are required to ensure 100% slab coverage.
