** NOTE TO SPECIFIER ** Heavy Duty Concrete Water Repellent Sealer - System can be applied to both existing and newly poured broom finish concrete that permanently fuses within the surface creating a breathable cross-linked insoluble internal membrane barrier which significantly increases concrete surface strength, combats freeze/thaw damage, and limits penetration of stains and damaging impurities such as oil, gas, grease, and salt without minimizing surface profile and traction. Heavy Duty system includes a surface enhancement application of lithium-silicate and siliconate solution that permanently fuses within porous substrates of concrete that creates calcium silicate hydrate crystals that will wear away only if the substrate itself wears away, increase surface strength, limit concrete dusting, limit penetration of stains and damaging impurities such as oil, gas, and grease, and remain breathable without altering the surface profile or leaving a topical residue.
