    My chimney crown is in need of repair. It is starting to crack in numerous spots. I was thinking of just slapping on another layer of cement over the old cracked one, then using some kind of water sealant like UGL Drylock. What do you guys think?

    Also have seen some crown sealers for this but they want over $100 for 2 gal of the stuff. Is there a cheaper way to do this? Thanks.

    This is not a repair but to slow the weathering process down oncan get concrete patch in a caulking tube form. If adding a thin layer
    then you need to coat the exinting cement wit a bonding agent like weldabond first found at most masonry supply dealers

    I had a chimney sweep seal the crown on one of our chimneys about 5-6 years ago with the Crown Seal product. It has held up quite well, although it is expensive.

    I have used Quikwall Surface Bonding Cement (http://www.quikrete.com/catalog/QUIKWALLSurface-BondingCement.html) on two other chimney crowns and it too has held up well. It is designed to go on thinly and is waterproof. It is not flexible like the Crown Seal, but is reinforced with fiberglass. I havn't seen any cracking on either crown in the 4+ years since repairing them. It is much less expensive than the Crown Seal.
