Penetrating Water Repellent Finish - KEIM SILAN-100 WATER REPELLENT

KEIM Silan-100 Water Repellent is a clear 100% Silane that deeply penetrates porous masonry and concrete surfaces with alkaline pH values. Because of the tiny molecules, it deeply penetrates the surface, offering optimal performance and long-lasting protection, and provides a flat finish with no gloss or sheen, maintaining original surface aesthetics. When correctly applied, Silan 100 produces a water beading or a water sheeting effect. The pores and capillaries of treated substrates are internally lined but not filled like paint or coating. This ensures the substrate doesn't trap moisture and the surface remains entirely vapor permeable (breathable).

Benefits

• Completely vapor permeable—allows substrate moisture vapor to freely escape without damaging water repellency

• Penetrates deeply and chemically reacts within pores of masonry and concrete for superior water repellency and durability

• Abrasion resistant

• Easy to use—brush, roll or pump-up sprayer

• Does not form a residue on metal, glass windows or painted surfaces

• 100% active silane means no waste and highest performance

• Protects against chloride ion and other chemical penetration

• Deep penetration into absorbent masonry ensures long-term durability
