CL-621 is a low-VOC solventborne acrylic sealer designed to permanently seal concrete and masonry surfaces. Application of CL-621 provides a non-yellowing high gloss finish which will protect the surface from water, dust, stains, and dirt. CL-621 may be used on new and old outdoor surfaces. The carrier solvents used in CL-621 are balanced to create a low viscosity, deep penetrating and quick drying sealer that is ideal for low build roller and pump-up spray and back-roll applications. CL-621 provides high gloss color enhancement for stained, integrally colored concrete, and porous masonry surfaces. On-site mockup tests are highly recommended to confirm that appearance requirements will be met and to determine both appropriate surface preparation and application techniques.
