    ChimneyRx Crack and Joint Sealant is used to seal larger cracks and other defects that cannot be corrected with water repellents alone. ChimneyRx Crack and Joint Sealant is a brusable, elastomeric sealant that is used to repair exterior cracks in mortar joints on chimneys, brick walls, and between concrete masonry units.

    ChimneyRx Masonry Crack and Joint Sealant seals cracks up to 1/8" wide on brick faces and at mortar and brick joint interfaces to provide waterproof protection and minimize brick mortar repair. Depending on the size of the crack, Crack and Joint Sealant will dry clear to a milky white. Once it sets, it will prevent water filtration and subsequent damage while allowing water vapors to escape.

    Using ChimneyRx Crack & Joint Sealant will solve tough leak problems without the expense of tuck pointing or surface grouting. It will not significantly change the appearance of most walls, chimneys or masonry surfaces. A slight gloss will occur on dense surfaces which will lessen over time.
