Crown Seal by ChimneySaver:

Crown Seal by ChimneySaver is a pre-mixed, trowel grade, elastomeric coating that forms a flexible waterproof membrane designed to repair & protect chimney crowns & more from moisture intrusion & to withstand severe weather & thermal stress. It can also be used as a bonding mortar to replace badly spalled brick units or for parging over brick faces that may have spalled, if remaining brick is solid. CrownSeal can be easily colored using standard mortar dye. It remains permanently flexible and carries a 10 year warranty.

A crown or splay as it is sometimes called is very important for the best protection of the chimney construction that is beneath the crown by helping to prevent the need for fireplace chimney repairs & chimney rebuilding. This crown helps to protect the top of the chimney starting at the fire clay flue liner & hangs over the chimneys edge (drip edge). Most masonry chimneys that have "crowns" are built inadequately. These "crowns" are constructed from common mortar mix, the same mixture used to lay the bricks of the chimney. This mortar is not designed for and will not withstand years of weather abuse without cracking, chipping or deteriorating; situations that allow water to penetrate the chimney and cause the need for fireplace chimney repairs & chimney rebuilds.
