Read the Label - Solvent Base Water Repellent

ChimneySaver® Solvent Based Water Repellent protects masonry chimneys against damage due to penetration by water and waterborne chemicals. ChimneySaver is not a surface coating. It penetrates ¼” or more into treated surfaces and bonds with the surface to provide long lasting protection against water penetration, even at hairline cracks. ChimneySaver will not change or alter the color or appearance of compatible treated surfaces. ChimneySaver becomes water repellent after 4-6 hours of exposure to UV light and atmospheric moisture and increases in strength for several weeks after treatment. It is 100% vapor permeable and allows water vapor produced during the combustion process to escape from the chimney.


Before use, read all directions for preparation, application, and safety information. Always test each type of surface before application for suitability and desired results before proceeding with general application.

SURFACE CONDITIONS: Surfaces must be free from dirt, dust, stains, efflorescence, coatings or other foreign materials which might interfere with penetration of water repellent. Repair loose or missing mortar joints and allow 72 hours for cure before application of water repellent. Repair and/or replace damaged masonry units. Allow new masonry and concrete to cure at least 28 days before applying water repellent.

WEATHER CONDITIONS: Surface and air temperatures should be a minimum of 40°F and a maximum of 100° F for three hours following application. Do not apply to frozen or frost covered surfaces. Do not apply to wet or water saturated surfaces, or when rainfall is expected within six hours unless adequate protection with a polyethylene film, or its equivalent, is provided.

Limitations: Do not use on asphalt-based material and surfaces. Do not apply to painted or glazed brick or tiles. This product is not intended for interior use or for resistance to hydrostatic pressures.


When transferring this product to another container, safe grounding procedures should be used.

Vertical: Agitate before using. 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 inch 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; retreat within three to five minutes after initial application. A wet treated surface may be agitated with a soft bristle scrub brush to ensure more even distribution and greater penetration. Remove overspray immediately with a dry rag or solvent wipe.

Horizontal: Agitate before using. 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 a dry rag or solvent wipe to remove overspray as soon as possible.

Drying Time: 2-6 hours depending on temperature and humidity.

Clean-up: Thoroughly rinse spray equipment with mineral spirits. Clean rollers with mineral spirits. Rinse thoroughly.

Storage and Disposal: Do not store in temperatures above 100°F. Dispose of this container and any unused product in accordance with all federal, state and local regulations.

Helpful Tips: Protect surrounding vegetation. Wet leaves and greenery before and after application or cover with plastic. Asphaltic material may be damaged if soaked. Protect from run-off with drop cloths or other absorbent material. Most oil-based paints may be applied over ChimneySaver after a 24 hour drying period.

Spills and leaks: Eliminate all sources of ignition. Soak up small spills with absorbent material. Dispose of in accordance with local, state and federal regulations.

Coverage Guidelines: Coverage rates will typically range from 90-150 sq. feet per gallon depending upon surface porosity.

Caution: Over application of material may cause darkening of surface. Accumulation of product on ladders, scaffolding, roofing, etc. may result in a slippery surface. Prevent overspray from accumulating. Clean surfaces as necessary
