DeepSeal Natural ‘W’
Unlike film-forming coatings such as those based on acrylic, polyurethane or epoxy resins. DeepSeal water repellents do not seal the pores at the surface of mineral masonry. They simply form a very thin layer on the pore walls. Water can no longer penetrate in liquid form into capillaries that have been rendered water-repellent, since, as a polar liquid, it is unable to interact with a non-polar, hydrophobic surface. In other words, pores, which have been DeepSealed and are therefore hydrophobic and can no longer, be wetted by water.
