Concrete Sealers


Iso-Flex 618-40 W.B. is a V.O.C. compliant, clear, penetrating, breathable 40% water-based silane sealer emulsion. The sealer is composed of a concentrate alkylalkoxy silane emulsion in water diluted at the jobsite. Iso-Flex 618-40 W.B. is specifically developed to protect new and existing concrete structures against the damaging effects of moisture intrusion, freeze/thaw scaling, and chloride-ion (salt) intrusion


Iso-Flex 618-100 Corrosion Reducing Sealer is a clear, penetrating, breathable 100% blended silane sealer. It is specifically developed to protect new and existing concrete structures against the damaging effects of moisture intrusion, freeze/thaw scaling, and, most importantly, chloride-ion (salt) intrusion. The design of this system ensures that the protection provided is not simply on the surface, but deep within the substrate, sometimes as much as ¾”. Our unique 100% silane system chemically reacts with the substrate to form a hydrophilic barrier deep within the surface.
