Surface Preparation (Residential & Commercial): Pressure wash when possible using pure water. Be sure the surface is clean and completely dry before the application of the coating. Read all label instructions before beginning. Surface must be in savable condition, clean and dry, and should have proper drainage. Always run a test patch first in an inconspicuous area, to ensure that proper adhesion and drying occurs and the product works to your satisfaction. Apply Ames® Peel & Stick™ adhesive seam tape and tape on all badly deteriorated fasteners, rubber washers, joints, seams and around vents. Do not use any soaps or detergents to clean the surface.

Step 1: Seam Tape all seams, joints, cracks, splits and transitions around vent pipes, air conditioning units and areas where two dissimilar materials come together.
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® Maximum Stretch® and Ames® Iron Coat® is 100 sq. ft. per gallon per coat. Rough or uneven surfaces may require additional product. More than one coat of Ames® Maximum Stretch® or Ames® Iron Coat® is recommended. More coats equal longer life.
Weather & Drying Guidelines: Ames® Super Primer™, Maximum-Stretch® and Iron Coat® 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-up, Storage, and Disposal: 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.
