So, how does it work? Masonry Responder's advanced formula penetrates deep into the pores of your masonry. The silane and siloxane molecules react with the silica and other minerals within the masonry to form a breathable, water-repellent matrix. This allows vapor to pass through, preventing moisture buildup, while effectively blocking water absorption, protecting against cracking, spalling, and efflorescence.

With its no-sheen natural finish, Masonry Responder is designed to not alter the appearance of your masonry. It is also ideal for use on many historic structures.
