Description

Repairing flashings that have been tarred over, split, cracked, or are in disrepair is easy with FlashSeal. It’s like installing a custom-fit rubber boot at the base of the chimney! It remains permanently flexible and has a 7 year warranty when used with FlashSeal Reinforcement Fabric.

For complete chimney protection, we recommend waterproofing the chimney and sealing the chimney crown.

ChimneySaver Water-Base Water Repellent

ChimneySaver Water-Base Water Repellent is a penetrating, V.O.C. compliant, water repellent which contains a proprietary modified siloxane. This water-based siloxane penetrates masonry up to 1/4 inch or more depending on surface porosity and moisture content at the time of application. ChimneySaver Water-Base 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 Water-Base Water Repellent to become an integral part of the substrate and provide long term water repellent protection.
  • 10 Year Warranty
  • VOC Compliant in All States
  • 100% Vapor Permeable
  • Non-Glossy Look
  • Efflorescence Protection
  • Freeze/Thaw Protection
