Description
Moisture is always present in masonry and concrete! Sealers and silicone coatings form a water resistant surface film, which traps water vapors inside - if they can't escape, issues arise such as spalling, scaling, deterioration, and freeze-thaw damage. ChimneySaver Water Repellent is designed to be 100% vapor permeable, allowing water vapors to escape when the chimney is in use - unlike other products found in hardware or home improvement stores.
ChimneySaver - Water Based
- The most popular formula among our available ChimneySaver products! This water repellent contains a proprietary modified siloxane that penetrates masonry up to 1/4" or more, depending on surface porosity and moisture content at the time of application. This product forms strong permanent bonds beneath the surface that provide long term water repellent protection. This product is available with a ten-year warranty.
ChimneySaver - Water Based, Stainblocker
- This product forms an invisible barrier that blocks the return of stains, yet doesn’t change the appearance of the chimney surface. This product protects masonry chimneys against damage caused by water penetration and waterborne chemicals by penetrating 1/4" or more into treated surfaces, and bonds with the surface to provide long lasting protection against water penetration, even at hairline cracks. This product is available with a seven-year warranty.
ChimneySaver - Water Based, Block Chimneys
- A high performance, penetrating blend of silane/siloxane, and acrylic elastomers which bond with the minerals in block chimneys and CMUs (concrete masonry units) to provide long-lasting water protection. This product is an architectural grade repellent that meets all industry guidelines for selection of commercial water repellents of block chimneys or other CMUs. This product is available with a seven-year warranty.
ChimneySaver - Water Based, Multi-Purpose
- An architectural grade product that meets all industry guidelines for selection of commercial water repellents for masonry, bonding with the minerals in concrete and masonry to provide long-lasting water repellency. ChimneySaver Multi-Purpose Water Repellent is an all-purpose, heavy-duty water repellent that is commonly used on walkways, patios, driveways, and other masonry surfaces. It contains SaltShield, making it resistant to chlorides from sea salts and road/sidewalk salts. This product features a seven-year warranty when used on vertical surfaces.
ChimneySaver - Solvent Based, V.O.C. compliant is a penetrating water repellent that contains a proprietary, modified siloxane in a V.O.C. compliant solvent carrier.
ChimneySaver - Solvent Base, Not V.O.C. compliant is a penetrating water repellent that contains a proprietary, modified silane/siloxane blend in a mineral spirits carrier.
- Both these water repellents penetrate masonry up to 1/4" or more depending on surface porosity, and moisture content at the time of application. These products form strong, permanent bonds beneath the surface and create hydrophobic zones that prevent water molecules from penetrating, while still allowing water vapors to escape. The chemical bonds formed in this process provide long-term water repellent protection. These products are both available with ten-year warranties.
- Please Note: Non V.O.C. Compliant products are not available in all states
The average coverage rate for most chimneys is about 125 square feet per gallon of ChimneySaver product. Based on this estimation, a 5 gallon container of ChimneySaver treats roughly 2-5 chimneys, depending on the size and porousness of the masonry. Please refer to product data sheets for most accurate coverage information.
Pro Tips:
- Be sure to spray the roof down before applying these products!
- These products not recommended for slate roofs.
- Product dry time is 1-2 hours. Before applying, allow 6 hours before rainfall.
- For cleanup, simply use soap and water while product is still wet. Be sure to remove over-spray from non-target surfaces (especially windows and glass) before product dries.

Vertical Surfaces: Agitate surface before using product. Apply from bottom up using a low-pressure sprayer (10-25 psi) with a fan type nozzle, or by roller with a minimum 3/8" nap. Flood surface until excess runs down six to eight inches below spray or roller pattern. For maximum penetration and desired coverage rates, a wet on wet application is recommended; re-treat within three to five minutes after initial application. A wet treated surface may be agitated with a soft bristle scrub brush to ensure a more even distribution and greater penetration. Remove inadvertent over-spray from non-target surfaces immediately with soap and water.
Horizontal Surfaces: Agitate surface before using product. Apply a single application with low pressure sprayer or a deep nap roller so that surface remains wet for two to three minutes before final absorption. Avoid puddling or ponding; brush or broom to spread material until it thoroughly penetrates the surface. Block all drains and use absorptive coverings to contain run-off of excess material. Use soap and water to remove inadvertent over-spray from non-target surfaces as soon as possible.
Drying time: Two to six hours, depending on temperature and humidity.
Please Note: Product may cause darkening of pre-existing stains on masonry or concrete.
Coverage: Coverage rates will typically range from 90-150 sq. feet per gallon depending upon surface porosity. See coverage rate section. Do not thin product
