CrownSeal Crown Repair (2 Gallon)

CrownSeal is a proprietary, trowel-grade, elastomeric coating that forms a flexible, waterproof membrane to repair and protect chimney crowns from water intrusion. It dries in about 6 hours and cures in about 24 hours to a natural concrete/mortar appearance. Use on chimney corbels, the tops of masonry and parapet walls, or wherever a flexible waterproof membrane is needed.

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 is a long lasting and durable coating that requires no mixing or special bonding agents. CrownSeal can be easily colored using standard mortar dye. Available in 2 and 5 gallon pails. One gallon of material covers about 14-18 sq. ft. per gallon at 1/8″ thickness, or 7-9 sq. ft. at 1/4″ thickness.
