Penabrick WB

Product Description

Penabrick WB is a water-based, single-component, VOC compliant, silicone waterproofing sealer designed to penetrate and protect brick, stone, stucco and mortar.  Penabrick WB is a very low viscosity water repellent capable of penetrating most substrates.  It protects surfaces from rain, sleet, snow, de-icing chemicals and acid rain. Penabrick WB penet rates and adheres to most surfaces, producing a weather resistant sealer.  Penabrick WB should be used on surfaces that are porous and have not been previously waterproofed. Use Penabrick SB to retreat previously waterproofed surfaces.
