Description Technical Specs Extended Information

Crack and Joint Sealant (formerly CrackMagik) is a brushable elastomeric sealant for mortar joints used to repair exterior cracks in mortar on chimneys, brick walls and between concrete or stone masonry units. The product seals larger cracks and other defects that cannot be corrected with water repellents alone.

Crack and Joint Sealant seals cracks up to 1/8 inch wide on brick faces and at mortar and brick joint interfaces to provide waterproof protection. It dries to a clear, translucent, milky film. Crack and Joint Sealant prevents water infiltration and subsequent damage, yet allows water vapor to escape.

When applied to a properly prepared wall or chimney surface, Crack and Joint Sealant can solve tough leak problems without the expense of tuck pointing or surface grouting.

Crack and Joint Sealant is a chimney sealant product formulated specifically for mortar joints. This chimney waterproofing product is ideally used in combination with ChimneySaver Water Repellent to prevent leaking brick chimneys.
