Brick-Block Masonry Sealer is a silane/siloxane emulsion that acts a water repellent treatment for mineral substrates such as stone, brick, concrete and mortar. Brick-Block Masonry Sealer penetrates and provides water repellency by chemically reacting with the substrate. The active ingredients in this product are small molecules that penetrate deep into the substrate surface. After the emulsion breaks, these active ingredients react with moisture to produce hydroxyl groups. These hydroxyl groups bind with the substrate and each other to produce a hydrophobic treatment that inhibits water absorption into the substrate. This treatment does not change the appearance of the substrate and reduces spalling due to freeze-thaw and efflorescence, thereby increasing the life of the substrate.
