Help your chimney brick last longer and look better for years to come with Rutland Chimney Shield. With just one application it will form a barrier against water penetration while still allowing water vapor to escape. This means it will protect against spalling, deterioration, and freeze/thaw damage. This non-flammable, transparent formula works on most vertical, exterior masonry surfaces and is best applied with a low-pressure sprayer.
Approx. Coverage: Varies with the porosity of the chimney material.
