ChimneySaver® Water-Base with Stain Blocker protects masonry chimneys against damage due to penetration by water and waterborne chemicals. In addition, it will form an invisible barrier that blocks the return of unsightly stains. ChimneySaver Water-Base with Stain Blocker is not a surface coating. It penetrates 1/4” or more into treated surfaces and bonds with the surface to provide long lasting protection against water penetration, even at hairline cracks. It will not change or alter the color or appearance of compatible treated surfaces. This product becomes water repellent after 4-6 hours of exposure to ultraviolet 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.
DIRECTIONS FOR USE
Do not apply if standing water, ice, or frost are visible on surface to be treated. Do not proceed with application when temperature of surface, air and material is below 40°F or greater than 110°F, or when rain and /or temperatures below 40°F are predicted within 6 hours after application.
Surfaces must be free from dirt, dust, stains, efflorescence, coatings or other foreign materials which might interfere with penetration of water repellent. Stains should be removed prior to treatment using an appropriate cleaner. 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.
Vertical: Test small area of surface before starting general application to ensure desired results and coverage rates. Apply from bottom up using a low pressure sprayer (10-25 psi), 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; retreat within three to five minutes after initial application. A wet treated surface may be agitated with a soft bristle brush to ensure even distribution and greater penetration. Protect all adjacent glossy surfaces, paint films, windows, plant life, asphalt-based materials and all other non-targeted surfaces from overspray and rundown. Remove overspray from non-targeted surfaces immediately with soap and water. Apply to southern exposed areas during the coolest part of the day.
Horizontal: Apply a single flood coat using sufficient material so that the surface remains wet for a few minutes before final absorption occurs. If additional material is required to reach desired coverage rate, a wet on wet application can be used. Avoid puddling or ponding; brush or broom to spread material to more porous area. If applicable, block all drains and use absorptive coverings to contain runoff of excess material. Use soap and water to remove overspray as soon as possible.
Drying Time: To touch, two to six hours depending on temperature and humidity. Clean-Up: Thoroughly rinse spray equipment with clean water. Wash rollers with soap and water. Rinse thoroughly. Storage and Disposal: Do not store below 32°F. Dispose of this container and any unused product in accordance with all federal, state, and local regulations. Helpful Tips: Protect surrounding vegetation. Wet the 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 Water-Base with Stain Blocker after a 24 hour drying period.
Coverage Guidelines: Actual coverages will vary due to porosity of surface materials, but approximate coverage is 125 sq. ft. per gallon. Do not thin product.
