INTRAGUARD is a water-based, penetrating sealing compound for concrete and masonry surfaces. INTRAGUARD is water-repellent, specifically designed to reduce the intrusion of water and chlorides into the substrate. This proprietary blend of silane and siloxane penetrates into the pores of the concrete and masonry to reduce scaling caused by deicing salts as well as protecting vertical masonry surfaces from the ingress of water. Good concrete and concreting practices must be used, as INTRAGUARD will not be effective on improperly designed, placed or cured concrete.
