Certi-Vex Penseal 244 O/W

CERTI-VEX PENSEAL 244 O/W is a premium high solids solvent base breathable clear water repellent sealer that combines hydrophobic and oleophobic technologies, providing greater protection over standard water repellents by sealing out water, oil, grease and other staining from concrete and masonry surfaces. Certi-Vex Penseal 244 O/W  penetrates into new (14 day minimum) or existing concrete and masonry surfaces preventing the penetration of water, salts, and deicing chemicals, which often result in efflorescence, mildew growth, corrosion, scaling, spalling, surface erosion and other costly damage to concrete and masonry surfaces. Surfaces treated with Certi-Vex Penseal 244 O/W  have a totally natural appearance.

Ideal for parking decks, parking areas, shipping docks, aprons and building facades
