arrowhead Can be used on properly prepared, non-porous substrates and existing vinyl floors.

1. Pour all of Part B into Part A. Allow enough time for the material to flow completely out of the container. Parts A and B are packaged to exact quantity ratios for proper curing, so always mix complete units. Do not add other materials to the mixture. Use a mechanical mixer (slow speed, less than 375 RPM), and mix thoroughly to achieve a smooth, homogeneous mix. Avoid air entrapment and prolonged mixing; both will shorten the pot life of this product. Inadequate mixing will cause bond failure. Pot life at 73 °F (23.8 °C) is approximately 30 minutes. Do not mix more adhesive than can be used in a 30 minute period.

2. Pour the adhesive onto the substrate immediately after mixing, and spread using a 1/16” x 1/32” x 1/32” U-notch trowel. Do not allow it to sit in the container, and do not back roll the adhesive.

3. Lay the flooring material into the adhesive after it has been spread, taking care not to trap any air bubbles, and roll in both directions with a minimum 75 lb., three-section roller, checking for full adhesive transfer from the substrate to the back of the material. Roll again 2 to 3 hours later.

4. Allow no foot traffic for a period of 24 hours after the installation, and allow 72 hours for the adhesive to fully cure, before setting heavy furnishings or allowing heavy traffic.

Clean Up: Promptly clean all hands and tools with ethyl alcohol after mixing. Use ethyl alcohol applied to a clean, dry cloth to wipe up any adhesive residue from the surface of the flooring while still wet. Do not apply ethyl alcohol directly to the material. Always use caution when working with ethyl alcohol. Take care when removing the cured adhesive from the surface of the sheet vinyl. Using a clean, damp cloth, gently remove the adhesive by wiping from the surface. Due to the embossing of some products, it may be impossible to remove cured adhesive without permanent damage to the surface. Because of this, always attempt to remove the adhesive while it is still wet.

Limitations: Protect from freezing. Use only when the substrate temperature is 65 °F – 85 °F (18.3 °C – 29.4 °C).
