Best For First-Time Application
Superior Water Repellency 

ChimneySaver® Professional Water Repellent protects masonry chimneys against damage due to infiltration by water and waterborne chemicals. ChimneySaver Professional Water Repellent is not a surface coating. It permeates into the capillaries of the substrates and bonds with the surface to provide long-lasting protection against water penetration, even at hairline cracks. ChimneySaver Professional Repellent will not change or alter the color or appearance of compatible treated surfaces. ChimneySaver Professional Water Repellent is designed to create immediate water beading at the surface as well as develop long term hydrophobicity beyond the surface layer. It is 100% vapor permeable and allows water vapor produced during the combustion process to escape from the chimney.

How it Works

ChimneySaver Professional Water Repellent reacts with the minerals in masonry in the presence of ultraviolet light and atmospheric moisture. This reaction forms strong permanent bonds beneath the surface and creates a hydrophobic zone that prevents water molecules from penetrating, while allowing free migration of water vapors. The chemical bonds formed in this process allow ChimneySaver Professional Water Repellent to become an integral part of the substrate and provide long term water repellent protection.
