Read Material Safety Data Sheets before using this product. Trowel Grade – Apply to either vertical or horizontal surfaces using a smooth edge trowel. Coverage will vary depending on the desired thickness. To achieve a 1/16” thickness apply at the rate of 4 gallons per 100 sq. ft.; 1/8” thickness apply at the rate of 8 gallons per 100 sq. ft.; ¼” thickness apply in two coats at the rate of 8 gallons per 100 sq. ft. per coat. Brush Grade – Mix thoroughly just prior to using. Apply to horizontal roof surfaces with a fiber roof brush at the rate of 3 to 4 gallons per 100 sq. ft. Coverage will vary depending on the irregularity and porosity of the roof surface. Caulk Grade – Apply directly in and over cracks using a standard caulking gun. An application rate of ¼” x ¼” bead of caulk will yield approximately 75 linear feet per 30 oz. caulking cartridge. Coverage may vary depending on desired thickness and surface being caulked.
