CS-309-30 acrylic curing and sealing compound offers a 30% solids content. It is a clear, transparent, ready-to-apply, non-yellowing liquid compound formulated from special acrylic polymers and quick-evaporating solvents that effectively and economically cures and seals freshly placed concrete. CS-309-30 meets the 350 g/L VOC limit for concrete curing compounds.

CS-309-30 is ideal for application on commercial and industrial concrete surfaces, sidewalks, patios, multi-level parking decks, driveways, and parking areas … wherever you want to simultaneously cure and seal exterior concrete surfaces. The use of CS-309-30 on any exterior concrete surface provides a durable, long-lasting finish that has improved resistance to chemicals, oil, grease, de-icing salts, and abrasion. CS-309-30 provides an attractive, low sheen finish that enhances the natural appearance of the concrete.
