MasonryDefender Chimney Flashing Sealer seals and protects chimney flashings (where the chimney meets the roof) as well as any other protrusions in a roof including skylights or vents. It provides a long lasting, flexible, waterproof membrane that protects against water intrusion. This product is ready to use and can be easily applied with a paint brush. Unlike other tar-based products, this product is permanently flexible and will not crack or become brittle.
Before use, read all directions for preparation, application, and safety information. Always test each type of surface before application for suitability and desired results before proceeding with general application. Surface and air temperature should be a minimum of 45º F at the time of application but not greater than 95º F. Do not apply if temperature is expected to drop below 45º F within a 4 hour period. Do not apply to frozen or frost covered surfaces. Do not apply to water saturated surfaces and/or when rain is expected within four hours unless adequate protection with a polyethylene film or its equivalent is provided. Store unused product in an airtight container above 32º F.
Surface to be coated must be structurally sound, not loose. Surface must be clean and dry. Place drop cloths at base of chimney to protect roof from inadvertent spills. Brush surface to be coated with a stiff poly or wire brush to remove loose particles. To produce a clean edge, the use of duct tape will produce clean edges and enhance the appearance of the repair.
Using a brush, apply a liberal coat of material, making sure to fill all cracks and voids completely. Extend application beyond problem area about one inch.
