Roof Tar Sealant & Coating
Ames® Super Elasto-Barrier® can be applied with a paint brush, a push broom, a low nap roller with a long handle, or a Commercial Airless Sprayer. You will also need Ames® Peel & Stick™ Seam Tape, as well as scissors or a utility knife. For larger commercial jobs, we recommend using a commercial grade airless sprayer. Graco, Bulldog, or Titan brands work well. Click Here for Sprayer Specifications
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. Be sure surfaces are clean and dry before the coating application. 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, and mask all sensitive areas before starting.

Step 1: Prime with two to three coats of Super Elasto-Barrier® until roof surface is smooth and sealed.
Step 2: Roll the Contouring Roof Fabric™ into the wet coating using the push broom or roller until the coating comes up through the fabric and totally saturates it. Avoid folds and wrinkles. If you choose to overlap the fabric, overlap its entire length by three to four inches. Repeat this process until the entire surface is completely covered with fabric. Allow the embedded fabric to dry completely for 24 to 48 hours. Apply an additional coat over the surface to completely seal and fill all remaining pinhole openings in the fabric.
The minimum application of Super Elasto-Barrier and Maximum-Stretch is 2 gal/100 sq. ft. for each product. Low spot areas would have a minimum of 5 gal/100 sq. ft. total including Super Elasto-Barrier 3 gal/100 sq. ft., Contouring Roof Fabric, and Maximum Stretch 2 gal/100 sq. ft.
Weather & Drying Guidelines:
Ames® Maximum-Stretch® or Ames® 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.
