How do I Protect my Chimney Stack?
All new and existing masonry structures are susceptible to water damage and, even if repaired, will continue to deteriorate if not protected. However, water damage can be prevented by choosing to apply a water repellent rather than a conventional water sealer. The difference could save you hundreds, or even thousands of dollars in repairs because sealers actually damage masonry.
That’s why we are big fans of ChimneySaver Water-Based Water Repellant. Unlike waterproofing sealers that remain on the surface, ChimneySaver penetrates deep enough to protect masonry from destructive water penetration while maintaining the structure’s vapor permeability. While moisture from a variety of sources is always present in masonry and concrete, sealers and silicone coatings form a water resistant surface film which traps water vapor inside. Chimney systems are especially vulnerable to condensation because water vapor is a large component of flue gases. Most of the water vapor escapes out the flue, but some will pass through tile liners and the mortar joints between the liners. If these vapors cannot escape, they will contribute to spalling, scaling, and, given how chimneys are highly exposed to the elements, eventual structural deterioration.
ChimneySaver contains patented siloxanes small enough to penetrate most masonry pores up to ¼” or more, forming strong bonds with the silica in masonry and concrete. Because of this bonding process, one application of ChimneySaver provides up to ten times the water repellent protection of typical sealers while maintaining the masonry’s breathability and extending the life of the chimney. That’s why SaverSystems offers a ten year warranty on their water repellent, as they do with another remarkable product, trowelable CrownSeal.
