Mixing Ratio: 4 quarts (3.8 L) of water per 40 lb. (18 kg) bag
For smaller batches, use 3.5 parts powder to 1 part water by volume
Coverage: 25 sq. ft. per 40 lb. (18 kg) bag at 1/4’’ (2.3 sq. m at 6 mm)
50 sq. ft. per 40 lb. (18 kg) bag at 1/8’’ (4.6 sq. m at 3 mm)
Coverage will vary depending on the texture of the surface being smoothed.
Performance
Initial Set (ASTM C191): Approx. 30 minutes
Final Set (ASTM C191): Approx. 90 minutes
Compressive Strength (ASTM C109/mod – Air cure only): 4,200 psi (294 kg/sq. cm.) at 28 days
