ChimneySaver Flash Seal
FlashSealTM Elastomeric Flashing Sealant

DIRECTIONS FOR USE
Preparation: Clean surfaces to which product will be applied with stiff brush to remove any dust, dirt, or debris. Measure and cut enough reinforcement fabric to completely cover the repair. Work the lowest side of the chimney or vent first, overlapping reinforcement fabric as you would shingles. Note: White FlashSeal can be colored using any standard mortar dye. To color, remove all the FlashSeal you will need for the job to another container and add mortar dye one drop at a time, mixing until desired color is reached.
Stir product well. Apply approximately 1/8” of coating to the surface to be sealed. Make sure product fills all cracks and holes entirely and extends about one inch beyond the edges of the pre-cut fabric. Using a brush, embed the pre-cut fabric into the first coat of FlashSeal. The FlashSeal should extend beyond the edges of the fabric and fill the holes in the fabric. Apply a liberal topcoat of FlashSeal making sure to completely cover the fabric and extend beyond the problem area about one inch. Note: On hot days FlashSeal will dry quickly. Work in 2-3 ft. sections. Use of duct tape will produce clean edges and enhance the appearance of the repair. See step-bystep photo instructions on the web at: www.chimneysaver.com/ FlashSeal. Coverage: 1 gallon of FlashSeal covers approximately 28 linear feet. Clean-Up: Soap and water while product is still wet. Note: Do not use in cold, damp rainy weather or product may wash away. Allow at least 12 hours of dry, clear weather for proper curing. Apply at temperatures above 45° F.
