Usage Instructions

Preparation:

1. Surface Assessment: Ensure the substrate is structurally sound, dry, clean, and free from dust, dirt, oil, grease, paint, curing compounds, and any other substances that may impede adhesion.
2. Temperature Conditions: The substrate temperature should be between 65°F (18°C) and 90°F (32°C).
3. Substrate Profiling: For non-porous or glass-like concrete surfaces, mechanically profile the substrate to an ICRI concrete surface profile (CSP) #2 to #3 standard using methods such as shotblasting or diamond grinding.

Application:

1. Trowel Selection: Remove the clip-on trowel attachment provided inside the pail. Select the appropriate trowel notch size based on the flooring type and desired spread rate.
2. Adhesive Application: Using the flat side of the trowel, key the adhesive into the subfloor to form a continuous film. Immediately spread the adhesive with the notched side of the trowel, holding it at a 60° to 90° angle to ensure 100% coverage without voids.
3. Working Time: Only apply as much adhesive as can be covered within 45 minutes to prevent premature curing.
4. Flooring Installation: Place the flooring material into the adhesive, pressing firmly to ensure full contact. Roll the installed flooring with a 100-pound roller to ensure proper adhesive transfer and eliminate air pockets.
5. Curing Time: Protect the installation from light traffic for at least 12 hours and from heavy traffic for at least 24 hours to allow the adhesive to cure properly.

Cleanup:

• Immediately remove any adhesive smudges using a solvent-based urethane cleaner while the adhesive is still fresh.
• Note: Once cured, the adhesive is extremely difficult to remove. Do not use water for cleanup.
