This adhesive is formulated for use on porous/moisture-absorbent substrates only — primarily wood roof decking. Not intended for: • Rubber-to-rubber seaming • Adhering rubber to metal surfaces • Adhering rubber to fiberglass surfaces • Adhering rubber to plastic surfaces For non-porous surfaces or specialty applications, contact Dicor directly.
Surface Preparation: 1. Ensure all surfaces are clean and completely dry — clean, dry surfaces are required for optimum bond strength Application: 2. Stir adhesive thoroughly before use. Keep container covered when not in use 3. Apply adhesive evenly to the substrate using a 9" wide short nap roller at 160–180 sq. ft. per gallon 4. Roll EPDM or TPO membrane onto the adhesive immediately — no waiting time is required 5. Take care to minimize air trapped between the substrate and membrane Bonding: 6. Mate surfaces with only enough pressure — evenly applied — to ensure good contact. Excessive pressure can redistribute adhesive unevenly 7. Use a push broom or squeegee to remove any air pockets and ensure full membrane contact

Keep from freezing. Store at 50°F–60°F for maximum storage life. Do not store below 40°F — freezing will damage the adhesive. When containers are "empty," residual vapor and product may remain. Do not reuse empty containers or remove labels. Dispose of in accordance with applicable regulations.
