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
  • Can Be Used On Most Vertical, Above-Grade Masonry

Sorbent Pads

Sorbent Pads are great for protecting roof shingles from ChimneySaver overspray. When spraying ChimneySaver through a pump-up sprayer, overspray that is allowed to dry on the roof can discolor shingles, making dark spots appear where overspray lands. This soft, absorbent material prevents overspray from soaking through and are designed to stick to the roof without sliding off. Sorbent Pads are available in packs of six. Don’t forget these when doing your next ChimneySaver job.
