Hydrophobic treatment for cement and lime-based products, brick and natural stone. Eco-friendly and practically odourless white liquid consisting of siloxanes in a solvent-free aqueous solution. On drying, BENFERDROP becomes completely transparent and invisible, leaving the original appearance and colour of treated surfaces unaffected. The product’s superior water repellent properties protect substrates from troublesome infiltrations of water that can result in blooming and permanent damp, or cause parts of the substrate itself to break off or crumble due to frost. BENFERDROP will not produce unsightly white efflorescence on treated surfaces.
