MasonryDefender Chimney Crown Sealer protects most masonry or concrete chimney crowns. It provides a long lasting, flexible, waterproof membrane that protects crowns from water intrusion.

DIRECTIONS

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 PREPARATION

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. Larger cracks and voids can be filled with fast setting patching cement or a premium grade latex caulking. Chimney Crown Sealer may be applied over top of the caulk before it cures as the caulk will cure underneath the product. To produce a clean edge, place duct tape beneath the crown, over the top row of brick and then above the crown, one inch from the bottom of the protruding flue tile. Remove tape when application is complete.

APPLICATION

Lightly mist the crown with water using a spray bottle. Using a synthetic bristle paint brush, brush a thin coat of material over the entire crown. Allow the first coat to set for a few minutes until it forms a tacky film, then brush a second, heavier coat over the first coat.
Coverage: Two coats of product will cover approximately 20 square feet per half gallon container, depending on texture and porosity of surface to be coated.
Dry Time: Dries to touch in 30 – 60 minutes. Product cures completely within 2 – 4 hours depending on temperature/humidity.
Clean-Up: Remove product from tools immediately after each use by scrubbing with a brush and water. To clean inadvertent spills from roofs, etc., remove excess and clean remaining product with a stiff nylon scrub brush and water. Rinse thoroughly.

CAUTIONS
