SealMaxx Siliconate Sealer - is a high-tech specially formulated concrete sealer and curing agent. This is the ONLY concrete sealer in the nation that forms a cross-linked resin (internal film) within the substrate surface. This means that the sealer will wear away only when the substrate itself wears away to the lowest penetration point of the sealer. Substrates sealed with the SealMaxx Siliconate Sealer become stronger, moisture repellent and resistant to stains from oil, gas, grease, salts, and other damaging fluids. While blocking liquids, it allows entrapped water vapors to escape at an optimum rate which facilitates a more productive curing cycle and fortifies the substrate against repeated freeze/thaw cycles. It meets most D.O.T. specs in the U.S. as well as ASTM 309 and 1315 for curing concrete. It comes with our exclusive 20 Year Guarantee which is replacement of sealer to any area that deteriorates after application. Material and labor are included. The quality of the concrete determines the effectiveness of the sealer.
