ChimneySaver VOC Compliant Solvent Base is great for initial treatments and re-applications. It is 100% vapor permeable, which means it won’t trap water vapors that may pass through the bricks when the chimney is in use, unlike other products found in most hardware or home improvement stores. Those products, when applied to a masonry chimney, can actually slow down water vapors as they pass through the chimney, which leads to water damage.
