A brushable elastomeric coating for chimney crowns that may be applied in temperatures as low as -40 degrees Fahrenheit.
This brush-able sealant is used to repair exterior cracks in mortar on chimneys, brick walls and between concrete or stone masonry units. It seals larger cracks and defects that cannot be corrected with water repellents alone.
CrownSeal forms a flexible waterproof membrane specifically formulated to repair and protect chimney crowns from water intrusion. It dries to a natural concrete/ mortar appearance.
