Various names: ChimneySaver, water repellent, masonry waterproofing, weatherproofing, waterproofing.

Description of product from the manufacturer: According to the Brick Industry Association, chimneys require special attention and maintenance to prevent costly damage caused by water penetration. Because chimneys project above the roofline, they are vulnerable to the elements. Nearly every chimney you encounter has signs of water damage! The first step is to determine the cause and then find the best corrective measures. ChimneySaver, the first product developed specifically for chimneys, has been used successfully by leading chimney professionals for nearly 20 years. According to ASTM tests conducted at the University of Wyoming, it reduces water penetration into the masonry by 99.9%.

It’s also 100% vapor permeable, which means it won’t trap water vapors that may pass through the bricks when the chimney is in use, unlike other products found in most hardware or home improvement stores. When applied to a masonry chimney, those products can actually slow down water vapors as they pass through the chimney, which leads to water damage.

Moisture from a variety of sources is always present in masonry and concrete. Sealers and silicone coatings form a water-resistant surface film that traps water vapors inside. If these vapors cannot escape, they will contribute to spalling, scaling, deterioration, and freeze-thaw damage. ChimneySaver is a 100% vapor permeable, non-film-forming water repellent that penetrates and lines masonry pores.
