Barrier EXT

BARRIER EXT | OUTDOOR TOPICAL SEALER
BARRIER EXT
Modern Stone’s Barrier EXT is a highly durable, chemically resistant, film forming sealer designed for use on exterior and interior stone and masonry surfaces. Barrier EXT’s UV resistant formula will not yellow or cloud over time and will strongly resist the harsh effects of outdoor weathering. Its water-based, satin finish requires minimal coats in order to impart extreme strength and beauty to a substrate’s surface. Barrier EXT is also an excellent choice for indoor applications that endure significant wear. Use on slate, saltillo, terra cotta, concrete/masonry, sandstone, tumbled marble, quartzite and other porous substrates where a gloss finish is desired.
