Directions
In a well-ventilated area, clean both surfaces with acetone or equivalent solvent to prepare the surface. Allow surface to fully dry. Apply 1 oz./sq. ft. of ExtremeGrip® Vinyl Cement to both surfaces. Allow 5-10 minutes for drying. Once the adhesive achieves tack, firmly press both layers together, using a roller for best results. Bond will strengthen with time. Let set 24 hours to achieve initial cure. Product fully cures in 7 days.

Storage
Take measures to prevent the build up of electrostatic charge. Use explosion-proof equipment. Keep containers tightly closed in a dry, cool and well-ventilated place. Keep away from sources of ignition - No smoking. Solvent vapors are heavier than air and may spread along floors. Store locked up.

Performance may vary by application. Always test adhesives under your specific conditions to ensure suitability.
