ChimneySaver Legacy Solvent-Based Water Repellent
ChimneySaver Legacy Solvent-Based Water Repellent is a penetrating water repellent which contains a proprietary modified siloxane. This solvent-based siloxane penetrates masonry up to 1/4 inch or more depending on surface porosity and moisture content at the time of application. ChimneySaver Legacy Solvent-Based 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 Legacy Solvent-Based Water Repellent to become an integral part of the substrate and provide long term water repellent protection. 10 Year Warranty 100% Vapor Permeable Non-Glossy Look Efflorescence/Stain Protection Freeze/Thaw Protection Can Be Used on Previously Treated Surfaces Can Be Used on Driveways and Sidewalks 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 roof line, they are vulnerable to the elements. Nearly every chimney you encounter has signs of water damage! The first step is to determine the cause, 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. It reduces water penetration into the masonry by 99.9%, according to ASTM tests conducted at the University of Wyoming. 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. Those products when applied to a masonry chimney can actually slow down water vapors as they pass through the chimney leading to water damage. Whether to use Water-Base or Solvent-base ChimneySaver is available in both solvent (mineral spirits) and water-based formulas. The water-based formula is most popular, however, if a water repellent has previously been applied to the masonry, we recommend the solvent-based formula. Moisture from a variety of sources is always present in masonry and concrete. Sealers and silicone coatings form a water resistant surface film which trap water vapors inside. If these vapors cannot escape, they will contribute to spalling, scaling, deterioration, and freeze-thaw damage. ChimneySaver a is 100% vapor permeable, non film-forming water repellent that penetrates and lines masonry pores.
