100% Breathable

Moisture from a variety of sources is always present in masonry and concrete. Sealers and silicone coatings form a water resistant surface film which traps water vapors. If these vapors cannot escape, they will contribute to spalling, scaling, deterioration, and freeze-thaw damage. ChimneySaver is 100% vapor permeable - a non film-forming water repellent that penetrates and lines masonry pores. ChimneySaver offers the best protection because it releases water vapors and effectively reduces water absorption.

NOT A SEALER
ChimneySaver penetrates up to 1/4" or more and bonds to the silica in concrete and masonry. Because it is not a sealer, it does not change the color or
appearance of masonry.
100% BREATHABLE
ChimneySaver releases 100% of water vapors that can damage masonry.

SEALER
Sealers work by coating a masonry surface and clogging the pores. This can cause the surface to darken or appear glossy.
TRAPS WATER VAPOR
Sealers trap water vapors which can accelerate water damage. Sealers are not recommended by the Brick Institute of America.
