Applications

Review all technical data sheets, system sheets, labels, instructions, SDS, and Guide Specifications before applying. Cure time will vary based on temperature and atmospheric conditions. Prior to coating any surface, be sure the coating will adhere by performing an adhesion test (ASTM D903). Coating may be applied by brush, spatula or trowel. Do not apply when temperatures are below 40°F (4.4°C) or when precipitation is in the forecast within 8 hours.

Coverage

The first coat of Ever-Thane Roof Flash should be applied at the rate of 1.5 gallon/100 square feet or 150 sqft/gallon The wet film thickness, exclusive of aggregate is 24 ± 2 mils per coat at rate of 1.5 gallon/100 sqft or 150 sqft/gallon. For metal roofs, fasteners coverage count per 3.5 gal pail is 1400 square feet. For seams, 3.5 gal pail @ 24 wet film thickness, 6” on center will cover 295 linear feet. Coverage rate will depend on surface roughness and porosity.
