ChemMasters Vexcon Certi-Vex Penseal 244 100%


Sold in Store Only

CERTI-VEX PENSEAL 244 100% is a high performance, 100% solids, surface applied, low-VOC, clear penetrating water repellent silane sealer for concrete. When properly applied the treatment does not produce a surface build up, darkening or other effect on the color or texture of the surface leaving a natural appearance. The material’s small molecular structure allows for maximum penetration into new concrete (14 day minimum) or existing concrete surfaces.

Certi-Vex Penseal 244 100% prevents the penetration of water, salts and deicing chemicals, protecting the concrete from costly surface damage caused by freeze/thaw cycles, scaling, spalling, corrosion of structural rebar, wind driven rain, airborne contaminants and other severe weather conditions.
