All new and existing masonry substrates are susceptible to water damage and, even if repaired, will continue to deteriorate if not protected.
Chimneys are highly exposed to the elements and, if left unprotected, are susceptible to structural deterioration. It is important to address this problem before serious damage occurs. We recommend accomplishing this by waterproofing the entire chimney with ChimneySaver water repellent. This water repellent is superior to other products in many ways and comes with a 10 year limited warranty.
ChimneySaver contains patented siloxanes small enough to penetrate most masonry pores up to ¼” or more. These special siloxanes form 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.
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 vapors inside. If these vapors cannot escape, they will contribute to spalling, scaling, deterioration, and freeze-thaw damage. ChimneySaver is 100% vapor permeable –a non film- forming water repellent that penetrates and lines masonry pores.
ChimneySaver is an investment in long-term protection that will help prevent expensive reconstruction. No water repellent, however, is a substitute for good construction and workmanship. The first step in preventing water damage is to make necessary repairs to structural cracks, damaged crowns, flashings, deteriorated bricks, and mortar joints. The second step is to protect porous masonry from further water penetration by applying ChimneySaver water repellent.
