Certi-Vex Penseal CT O/W

CERTI-VEX PENSEAL CT O/W is a surface applied corrosion and stain prevention treatment for new concrete or as part of a corrosion repair system to existing concrete. The product is both a hydrophobic and oleophobic penetrating sealer that provides an organo-functional molecule to inhibit the electro-chemical interaction between rebar and chloride ions, oxygen and moisture within concrete. Easy to apply, Certi-Vex Penseal CT O/W penetrates the concrete and chemically bonds with steel, cement paste and other siliceous material present in concrete.
