Detailed Application Instructions

Products: Ames® Elasto-Barrier™ and Ames® Maximum-Stretch™

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. Follow seam taping instructions. Mask all sensitive areas before starting.


Step 1:
Prime with two to three coats of Super Elasto-Barrier at the rate of 3 gal/100 sq. ft. until roof surface is smooth and sealed.

Step 2:
Finish with one to two coats of Maximum-Stretch or a similar Ames product as needed to complete application.

Estimated Coverage:

The minimum application of Super Elasto-Barrier and Maximum-Stretch is 2 gal/100 sq. ft. for each product.

Weather & Drying Guidelines:

Ames’® Maximum-Stretch™ or Super 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.

Clean-up, Storage and Disposal:

Clean tools and small spills with water. Store unused product in its original container, tightly sealed and protected from freezing. Dispose of this product in accordance with local, state, or federal requirements.
