Read the Label - ChimneySaver Multi-Purpose Water Repellent

ChimneySaver® Multi-Purpose Water Repellent is an architectural grade product that meets all industry guidelines for selection of commercial water repellents for masonry. This high performance penetrating silane/siloxane blend bonds with the minerals in concrete and masonry to provide long-lasting water repellency. It is ideally suited for concrete where maximum chloride ion (de-icing salts) protection is needed. ChimneySaver® Multi-Purpose Water Repellent is breathable, non-film forming, and will not alter surface color or appearance.


SURFACE CONDITIONS: Surfaces to which ChimneySaver shall be applied 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 curing before application of water repellent. Repair or replace damaged masonry units. Allow new masonry and concrete to cure at least 28 days before applying water repellent.

WEATHER CONDITIONS: Do not apply if standing water, ice, or frost are visible on surface to be treated. Do not proceed with application of product 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 of application.


Vertical: Test small areas 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 6 to 8 inches below spray or roller pattern. For maximum penetration and desired coverage rates, a wet on wet application is recommended; retreat within 3 to 5 minutes after initial application. A wet treated surface may be agitated with a soft bristle scrub brush to ensure even more distribution and greater penetration. Protect all adjacent glossy surfaces, paint films, windows, plant life, asphalt-based materials, and other non-targeted surfaces from overspray and rundown. Remove overspray from non-targeted surfaces immediately with soap and water.

Horizontal: Apply a single flood coat using enough product so that the surface remains wet for a few minutes before final absorption occurs. If additional product is required to reach desired coverage rate, a wet on wet application can be used. Avoid puddling or ponding; brush or broom to spread product on more porous areas. If applicable, block all drains and use absorbent coverings to contain runoff. Use soap and water to remove overspray as soon as possible.

Drying Time: 2-6 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 leaves and greenery before and after application or cover with plastic. Asphaltic material may be damaged if soaked. Protect from runoff with drop cloths or other absorbent material. Most oil-based paints may be applied over ChimneySaver Multi-Purpose Water Repellent after a 24 hour drying period.

Caution: Over-application 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.
