SP Seal Coat is a one component coating that combines three high performance water-borne resins.
The coating is designed using a high quality elastomeric and a self-cross-linking resin system for long life and weathering, as well as against water that ponds, and having good dirt release. SP Seal Coat is used as a topcoat over Super Therm, HPC or other base materials. It remains flexible and is resistant to mold and mildew. Sp Seal Coat can be applied over most firmly bonded paints or foams. Allow the base coat to dry before applying the SP Seal Coat.
