Step 1: Prime with Ames® Super Primer™ at the rate of 1 gallon per 200 square feet per coat. Goes on milky white and dries clear in about 30 minutes to an hour. Once the Super Primer™ is completely clear, Ames® Peel & Stick™ Seam Tape™ may be applied to any seams, cracks, splits, transitions, around any vents or units and skylights, or where two unlike surfaces meet. For the tape to work properly, it has to be on a smooth surface.

Step 2: Next apply two coats of Ames® Super Elasto-Barrier® at the rate of 1 gallon per 100 sq. ft. per coat. (2 gallons per 100 sq. ft.) Allow proper drying time between coats. Work the product until it is smooth and looks consistent in thickness.

Step 3: Finish the application with two coats of Ames® Maximum-Stretch® or other similar Ames® acrylic roof coating at the rate of 1 gallon per 100 square feet per coat (2 gallons per 100 sq. ft.) for a highly reflective energy saving roof system. Allow proper drying time between coats.

Estimated Coverage:

Standard product coverage on a smooth surface for Ames® Super Primer™ is 200 sq. ft. per gallon per coat and the product coverage rate for Ames® Super Elasto-Barrier® and Ames® Maximum-Stretch® is 100 sq. ft. per gallon per coat. Rough or uneven surfaces may require additional product. More than one coat of Ames® Maximum-Stretch® is recommended. More coats equal longer life for your roof.

Weather & Drying Guidelines:

Ames® roofing products is best applied between 50° to 90° F (10° to 32° C) on warm dry surfaces. Apply when the streets are dry, the sun is in the sky and no inclement weather is forecast. Starts to dry in about 2-8 hours, depending on thickness of application and weather. It is recommended to allow a minimum of 24 hours between coats with no rain in the forecast and no freezing temperatures. Low temperatures, high humidity and evening and morning dew will require increased drying/curing time. Do not apply after 2pm for best drying. The earlier you can put it on, the better. Make sure any morning dew is completely dried off before proceeding.

Clean tools and small spills with pure water, no soaps or detergents needed. Store unused product in its original container, tightly sealed and protect from freezing. Dispose of this product in accordance with local, state, or federal requirements.
