(Up to 25 lbs/1,000ft2/24 hr.) CHEMPROOF FC is also suitable on calcium sulphate-based screeds with slightly higher residual moisture. Can act as a primer for absorbent, non-absorbent, as well as smooth surfaces. For interior and exterior use. Tack Free in 45 Minutes!!

Available in 3 Gal Units. 2 Gallons of Part A and 1 Gallon of Part B. 2:1 Mix ratio. Available in Clear only but can be pigmented with color packs (pods)

See Slow Curing version here which can be used in full flake broadcasts and give applicators a little bit more working time to apply the coating. Slow curing version is also good to use when conditions are hot as the fast curing version needs to be applied IMMEDIATELY once A and B are mixed.
