Read all label instructions before beginning. 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. Remove loose dirt and gravel, moss, and debris from the roof surface and power wash. Be sure that the surface is clean and dry before starting application of product. All major cracks, joints, and seams should be caulked with Blue Max® Trowel Grade liquid rubber. Do not use a silicone caulk. Large cracks may be filled with a sandable filler.
Step 1: Apply Elasto-Barrier® at a minimum rate of 3 gallons per 100 sq. ft. or until roof surface is smooth and sealed.
Step 2: Finish with Maximum-Stretch® at the rate of 2 gallons per 100 sq. ft. or a similar Ames® product.
Weather & Drying Guidelines:
Ames® Maximum-Stretch® or Elasto-Barrier® 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 2-8 hours, depending on thickness of application and weather; cures in 24 hours. Low temperatures, high humidity and evening and morning dew will require increased drying/curing time.
