Protectosil® BHN

Especially suited for the water repellent impregnation of mineral construction materials in outdoor areas.
Especially suited for use on cast-in-place, precast, glass fiber reinforced concrete (GFRC) and high-strength concrete, to protect the material against water, deicing salts and other waterborne contaminants. Alleviates deterioration of concrete due to alkali-silica reactivity. For use on bridge decks where fast drying is needed to minimize lane closures. For treating heavy-traffic wearing surfaces or areas that receive high salt concentrations (piers, coastal buildings), to provide a high-performance, long-lasting chloride screen.
Protectosil® BHN is not intended for below grade water-proofing.
