Protectasilane is a high quality water repellent silane for the impregnation of masonry.
This is a traditional Silane Sealer, containing below 50% of silanes, which makes it a more cost efficient product.

The product is designed to deeply penetrate into the capillaries of masonry surfaces and render the substrate water repellent. This water repellent zone significantly reduces the absorption of water or efflorescence or other water-borne staining materials and reduces efflorescence. The treatment will not significantly change the appearance of the masonry substrates and the vapour permeability.

However, a slight darkening of the surface may occur for some substrates. Protectasilane is recommended as a water repellent sealer for concrete and other permeable masonry building substrates such as stone, bricks, and ceramic tiles and grout.
