Certi-Vex Penseal 244 40% AIM

CERTI-VEX PENSEAL 244 40% AIM is a low VOC premium high solids solvent base breathable clear water repellent sealer that penetrates into new (14 day minimum) or existing concrete and masonry surfaces. Certi-Vex Penseal 244 40% AIM prevents 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 40% AIM have a totally natural appearance.

Ideal for bridge and parking decks, building facades and balconies.
