CS-309-25 OTC acrylic curing and sealing compound is a clear, transparent, ready-to-apply, non-yellowing liquid compound formulated with special acrylic polymers and VOC-exempt solvents that effectively cures and seals freshly placed concrete.

Once properly applied, CS-309-25 OTC provides a premium-grade seal for optimum moisture retention. This produces a hard, dense, high compressive strength concrete.
