5 Gallons of CrownCoat Brushable Buff Sealant - 300012

This brushable sealant has become a favorite among chimney professionals because of its unique quick drying, water-based technology and its easy brush-on application. CrownCoat is premixed and can be used wherever a long lasting waterproof membrane is needed. Fill larger cracks and voids with patching cement or high quality caulk, then apply two coats of CrownCoat. Using a 3" or 4" paint brush (not included), apply a thin first coat, then immediately follow with a heavier top coat. It cures completely in two to four hours and covers about 40 sq. ft. per gallon. That's nearly twice the coverage of competitive products! CrownCoat can be custom colored using standard mortar dye.
