Natraseal LVOC is a breathable, solvent-based, non-yellowing, transparent acrylic copolymer decorative concrete sealer, blended for maximum working time and easy application. Natraseal LVOC is a breathable, solvent-based, non-yellowing, transparent acrylic copolymer decorative concrete sealer, blended for maximum working time and easy application. The clear sealer minimizes common errors that can occur when applying traditional sealers, such as bubbles or whiting. Natraseal LVOC has longer working time than traditional 25% solids sealers and can be applied with a brush, roller or sprayer. This new generation sealer uses top quality resins and a solvent blend in order to penetrate deep into the concrete surface for enhanced breathability and less "capping off" of the pores. Combined with UV inhibitors, Natraseal LVOC minimizes potential whitening or yellowing. Natraseal LVOC meets all Canadian and U.S. VOC requirements, except California SCAQMD regions.
