• Do not apply over any adhesive residues, including cutback adhesive. • Do not install when the moisture vapor emission rate (MVER) exceeds 5 lbs. per 1,000 sq. ft. (2,27 kg per 92,9 m2) per 24 hours, when using the anhydrous calcium chloride test (ASTM F1869).
• Do not install when the relative humidity (RH) of the concrete slab exceeds 80% (ASTM F2170).
• Use only when the substrate temperature is between 65°F and 90°F (18°C and 32°C). SUITABLE SUBSTRATES:
