Water Repellents

Reliable Water Repellent Sealants

Provide reliable protection from water and atmospheric moisture for a wide range of masonry surfaces, including highly alkaline mortars and cement rich materials, with Pecora’s 100% Silane and Water-Based Penetrating sealers and water repellents.

These high-quality water repellents create a hydrophobic barrier that prevents the intrusion of water and water-borne salts into the structure. This greatly reduces damaging moisture penetrations into masonry and concrete, helping to avoid salt leaching, freeze-thaw cracking and corrosion of reinforcing bars.
