* Required Fields



Water-based solution designed for liquid repellent protection and waterproofing impregnation of mineral and stone surfaces. On application, a substrates outer layer is modified to create an invisible long lasting water repellent barrier with breathable properties. Protecting against water and dirt ingress, treated surfaces stay cleaner for longer, keeping paving and patios algae free, reduce frost damage of winter freeze-thaw cycles and prevent salt-efflorescence.

nanoSystem STONE Paving W3 penetrates deep into stone and mortar joints, providing the best possible protection against water, dirt, salt, acid rain and extreme weather conditions.

When applied to mineral surfaces, the result is a liquid repellent effect that causes water or oil droplets to bead on the surface that easily roll off or wipe away leaving the surface completely dry and free from staining or soiling. The surface is easy to maintain and cleaning with toxic chemical or detergents is no longer necessary. Just rinse with water as required.
