Chimney Defender Next Gen Crown Repair

Because of its unique quick drying water base technology and its easy brush on application, Next Gen Crown Repair has become a favorite among chimney professionals.  Next Gen Crown Repair 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 Next Gen Crown Repair. When applying to a "new" crown allow the crown 48 hrs. cure time before applying the crown saver. This will cover approximately 40 sq. ft. per gal.

Instructions for Use

The surface and air temperature should be above 45 degrees Fahrenheit for proper application. Make sure to not apply if the temperature is expected to dip below 45 degrees Fahrenheit for a period of 4 hours after sealer is applied. Do not apply on wet or saturated surfaces. Make sure that it does not rain for 4 hours after it is applied unless it's protected by a polyethylene film. Store unused product in an airtight container above 32 degrees Fahrenheit.

Application

The surface to be coated must be structurally sound, not loose, and the surface must be clean and dry. Brush the surface with a wire or poly brush to remove any loose material. If the surface has larger cracks, you can fill them with 100% silicone caulk. Before applying Next Gen Crown Repair lightly mist the top of the crown with clean water. Make sure not to flood the crown. Misting will help Next Gen Crown Repair penetrate the crown creating a strong bond. Use a 3 to 4 inch synthetic bristle paint brush. Brush a thin coat over the entire crown, working Next Gen Crown Repair into the crown like painting a wall. Once you have applied the first coat you will have to wait a few minutes before applying a second coat, so that the first coat will form a tacky film. To finish, brush a second heavier coat. For a clean finish, wrap duct tape around the brick sides of the chimney and the flue. Next Gen Crown Repair can be stored for 18 month shelf life.
