Certi-Vex Guard

CERTI-VEX GUARD is a clear innovative one step penetrating silane water repellent and cure & seal product that can be applied to new or existing concrete.  Available in three grades; matte, regular and high gloss, the products penetrate the pores and capillaries of the concrete reacting with the alkali and moisture to form a hydrophobic gel in the pores and a water retentive film on the surface.

This membrane, which meets ASTM curing requirements and the Chloride Ion Penetration requirements of NCHRP 244 forms a   film that restricts moisture loss allowing concrete to reach maximum hardness and reduces staining, chloride penetration, prevents intrusion of water, salts, deicer chemicals and acids that can result in costly damage to concrete and masonry.

This innovative one-step product eliminates the costly removal of curing compounds and time consuming water curing of fresh concrete when a protective penetrating water repellent sealer is desired. Once applied, the surface is properly cured and water repellent is one application and puts concrete into service weeks sooner.
