Crack & Joint Sealant
1/2 gal
No water repellent can stop water from penetrating small holes and visible cracks, and because nearly every chimney has them, we developed Crack and Joint Sealant — a unique, breathable, silicone elastomer. Think of it as a paintable caulk. Use it for sealing minor cracks (up to 1/8”) and defects in mortar joints where the mortar and chimney are otherwise sound.
