Preparation and Application Information

Material Preparation
Stir well. DO NOT THIN. Apply only to clean, dry surfaces. Keep container closed when not in use to prevent solvent evaporation. If stored below 60°F, the product should be conditioned in its unopened container at room temperature for at least 24 hours before usage.

Application
Clean all surfaces thoroughly. Make sure the surfaces are free of any oil residue. Spray apply a uniform coverage of adhesive to one surface at 300 – 500 sq. ft./gal. (7.4 – 12.3 m² /l). While the adhesive is still w et, combine substrates w ith sufficient pressure to ensure 100% contact.
