Crack & Joint Sealant

No water repellent can stop water from penetrating small holes and visible cracks, and because nearly everychimney has them, we developed Crack and Joint Sealant — a unique, breathable, silicone elastomer. Think of itas a paintable caulk. Use it for sealing minor cracks (up to 1/8”) and defects in mortar joints where the mortar andchimney are otherwise sound.
