Additional Details

Cure & Seal 309 is a solvent-based, non-yellowing, acrylic copolymer, concrete curing, sealing and dustproofing compound. This solvent based LVOC cure and seal is ideal for Canada and states with more stringent VOC regulations.

Cure & Seal 309 was designed for easy application, minimizing common errors that can occur when applying traditional low VOC products, such as bubbles or whiting. Apply this product with a brush, roller or sprayer.

When applied properly, Cure & Seal 309 creates a vapor seal that retains moisture for proper curing and dries to a dust- and tack-proof state in as little as 30 minutes, quickly providing protection from light rainfall, scuffing and foot traffic. Apply this product to freshly placed concrete or use it as a high-gloss, sealer on existing surfaces.

Cure & Seal 309 meets all Canadian and all U.S. VOC requirements except in California SCAQMD regions.
