Tradesman-Pro Polyurethane Wood Flooring Adhesive

Permanent Glue-Down Flooring Adhesive

Tradesman-Pro is a single component, water free, polyurethane adhesive formulated to bond engineered, solid and bamboo flooring to concrete, plywood and other approved substrates.

Tradesman-Pro is designed to trowel easily for fast-paced installations of flooring when applied as directed.

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

Tradesman-Pro 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. Tradesman-Pro is suitable for the installation of flooring over electrical warming and radiant heat systems.

Low VOC Wood Flooring Adhesive

Strong Adhesive for Solid Plank, Engineered Hardwood or Bamboo Flooring

Strong and easy to apply adhesives are essential to the health and longevity of any wood floor installation. The chemists at Epic Flooring have formulated a high quality-low VOC flooring adhesive which is easy to apply for fast flooring installation.

Prolonged exposure to VOCs can lead to nervous system, liver, and respiratory system damage. Epic Flooring’s Tradesman Pro flooring adhesive features low volatile organic compound levels, minimizing common air pollutants found in many flooring adhesives and promoting good indoor air quality. With Tradesman Pro, you’ll be sure your flooring has no ill effects on your health.

Tradesman Pro is a single-component polyurethane flooring adhesive which creates strong and lasting bonds for the installation of all types of flooring, from solid wood to bamboo and engineered flooring types.

Directions for Use of Solvent-Free Adhesives

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.

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-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 cutback adhesive residue, and do not install over cutback adhesive residue below grade or if there is or ever has been a moisture concern with the 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 or natural stone, all waxes and sealers must be completely removed. Highly reflective tile or stone should be lightly abraded with a sanding disk to improve adhesion.

Installation

Job-site conditions affect 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.

Installation 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 Tradesman-Pro to the subfloor using a ¼” X ¼” square 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

• Periodically check coverage of the adhesive during the installation. Solid and bamboo wood flooring require a 95-100% adhesive transfer between the substrate and flooring. Engineered flooring requires a minimum 80% adhesive transfer between the substrate and the flooring.
• Installation of unstable flooring such as bamboo or solid flooring is not recommended for below grade applications.
• On or below grade construction must have a functioning vapor barrier (6 mil poly or better) beneath the slab.
• Do not install dimensionally unstable wood such as solid or bamboo over existing sheet vinyl or VCT.
• Do not install flooring over perimeter bonded sheet vinyl.
• Slab temperature should be between 50°F-90°F during installation.
• Turn radiant heating or floor warming off during and for 72 hours after installation.
• Do not use on wet, dusty, contaminated, reflective or friable substrates. Do not use on sub-floors treated with sealers or curing compounds. Do not use on concrete slabs subject to hydrostatic pressure.
• Completely remove adhesive residue, sealers and contaminates by diamond grinding, shot blasting or scarifying.
• Use over gypsum concrete should be limited to substrates in that are in solid condition. Do not glue down flooring over gypsum concrete that is powdery and cracked.
• Gypsum concrete should have a minimum mix design of 2000 psi for engineered flooring and 2500 psi for solid or bamboo wood flooring.
• Do not use to install foam backed parquet.
• Refer to the flooring manufacturer’s recommendations and NWFA guidelines for acclimation and required expansion space as these requirements vary substantially.

Storage and Shelf Life

Pails of Tradesman-Pro 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. Tradesman-Pro 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.

Trowel sizes are suggested to maximize adhesive transfer. Uneven subflooring may require the use of a patching or leveling compound or the use of a larger notched trowel.
