A topical that breathes? Another reason Modern Stone is leading the way in the hard surface industry. Barrier EXT solves the common problems caused by applying a topical to outdoor stone and masonry surfaces. This highly chemically resistant sealer is designed to strongly bond to varied types of surfaces and create a hard, abrasion resistant layer of protection. Though extremely strong and highly UV resistant, Barrier’s true innovation lies in its ability to repel dirt and stains while still allowing the transmission of water vapor – in other words, allowing the substrate to breathe! Now you can protect your outdoor surfaces from the harsh effects of weathering without causing spalling within the interior of the stone or delamination of the topical layer. Barrier is an excellent choice for indoor surfaces where strength and chemical resistance is required.
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 semi-gloss finish is desired.
