A chimney crown can sometimes become cracked and allow water to flow into the chimney. Chimney Cricket can cover the crown with a rubbery substance that looks just like cement called chimney crown coat and, if the cracks are extensive, a new crown can be formed.
What Exactly Is A Chimney Crown and Chimney Crown Coat?
A chimney crown is a masonry roof that covers the roof your chimney. It prevents water from seeping into the masonry and chimney liner below. Water damaged or cracked chimney crowns can lead to costly repairs. A chimney crown coat will fill cracks and prevent further damage to the entire sructure.
Stop Water Intrusion With A Chimney Crown Seal
A chimney crown seal is a flexible waterproof sealant that is applied over the entire chimney crown. A professionally applied chimney crown seal stops further water intrusion. It's specifically formulated to withstand severe weather and thermal stress to which chimneys are exposed to. It’s flexible and forms a continuous, seamless coating with a textured appearance that can be troweled in a variety of mortar-like finishes. A chimney crown coat is designed for use over exterior masonry, stucco, poured concrete, precast concrete, and concrete block.
Component Protection
Chimneys require special attention to prevent costly damage, which results from water damage. Chimneys that project above the roofline are especially vulnerable to the elements.
A complete chimney protection program should include repairing the crown with chimney crown coat, as well as a treatment of water repellent. Flue tiles should have a chimney cap to help prevent water damage to the interiors. Attention should also be given to the flashing around the base of the chimney and all visible points of water entry.
