INSTRUCTIONS

Limitations

• For interior installations only
• Radiant in-floor heating should be off during installation
• Do not use this adhesive for pure vinyl or vinyl-backed products

Preparation
Subfloors must be structurally sound, dry, smooth, flat (≤ 3/16” within 10’), level, and free of excess moisture/alkali, and all substances (oil, wax, grease, paint, oil-based sealers, adhesive residue, etc.) that may inhibit the bond of the adhesive or the performance of the flooring or its installation. Moisture testing must be performed by ASTM F1869 with levels not to exceed 5 lbs/1000 ft2/24 hrs and/ or ASTM F2170 with levels not to exceed 90%. All substrate cracks, chips, holes, joints, high spots, and irregularities must be adequately repaired. Expansion or other moving joints must not be filled or covered with flooring. Patching compounds must be suitable for the use application, cement-based and polymer-modified, and applied according to the manufacturer’s instructions.

Installation
Materials and area temperature must be between 65-95°F with a maximum RH of 65% for 48 hours before and during installation as well as for 72 hours afterward. Large temperature or humidity increases or decreases can affect the flooring and performance of the installation. This product is ready to use and does not require mixing. Lift a corner periodically to ensure 100% coverage of adhesive to the flooring backing and the substrate to ensure a void-free bond. Spread adhesive uniformly. Adhesive ridges should be of sufficient height to achieve full coverage of the substrate and the deepest recesses in the back of the flooring material. Place flooring into the adhesive while the adhesive is still fresh. The amount of time in which you have to place the flooring will vary with temperature and humidity.

Clean-up
Fresh adhesive – warm, soapy water on a clean cloth. Dried adhesive – use mineral spirits sparingly with a clean, white cotton cloth. DO NOT POUR DIRECTLY ONTO FLOORING.
