Water-Based, Penetrating Water Repellent for Concrete and Masonry

A breathable, water repellent sealer, Hydroshed soaks into the substrate and forms a barrier that protects concrete and masonry from the damaging effects or water and salts, especially in freeze-thaw climates and marine environments. Hydroshed does not alter the appearance or texture of the substrate. 

With no need for special equipment, Hydroshed can be applied by brush, roller, or spraying with a common airless sprayer. It requires a coverage rate ranging from 100 to 150 ft2/gal. Extremely porous surfaces may require two coats of Hydroshed.  When this is necessary, use the “wet-on-wet” technique for best results. 


Hydroshed is a ready to use, water-based, siloxane/silane penetrating, sealer for concrete and masonry walls.
