What is Ames® Elasto-Barrier®?

For roof and deck waterproofing, use Ames® Elasto-Barrier® waterproof base coat. It is a great base coat for our other coatings and creates an impermeable bond. Elasto-Barrier® is elastomeric and expands up to 1000% to move with the surface and resist cracking and peeling. This waterproof deck coating is UV sensitive and must be top coated if used in a place where it is exposed to sun. Goes where the water flows and stops leaks. Flows into cracks and crevices.

Where to Use:

Roofs Including:
• Tar
• Rolled
• Gravel
• EPDM Rubber
• Concrete Roof Repair
• Plywood
• Roof Decks

Other Areas Including:
• Balconies
• Porches
• Living Areas
• Wood
• Roof Valleys
• Plywood Sub-Roofs
• Decks
• Grain Bins

*Ames® Elasto- Barrier® waterproof base coat is UV sensitive and must be top coated if exposed to sunlight.

Ames® Elasto-Barrier® waterproof deck coating is ready to use – no mixing required. It can be applied with a paint brush, a push broom, a low nap roller with a long handle or a Commercial Airless Sprayer. In addition, you will need Ames® Peel & Stick™ Seam Tape and scissors or a utility knife. For larger commercial jobs, we recommend using a commercial grade airless sprayer. Graco, Bulldog or Titan brands work well. Call for specifications, 888-345-0809.

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. Mask all sensitive areas before starting.

Estimated Coverage:
Standard product coverage on a smooth surface is one to two gallons per 100 square feet. More than one coat is recommended. More coats equal longer life.

Weather & Drying Guidelines:
Ames® Elasto-Barrier® is best applied between 40° 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 1-2 hours, depending on thickness of application and weather; Allow to cure for a minimum of 24 hours between coats. Low temperatures, high humidity and evening and morning dew will require increased drying/curing time.

Can be used in Conjunction with:
Peel & Stick® Seam Tape, Super Primer™ (for EPDM rubber roofs). Roof Fabric (for plywood and OSB roofs). Top coat with Maximum-Stretch®, Snow Seal®, or Iron Coat® roof coating. Ames® Elasto-Barrier® is UV sensitive and must be topcoated if exposed to sunlight

Durability and Longevity:
Ames® Elasto-Barrier® is a base coat and must be top coated. When top coated it will last for many years to come.

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.

    Overall I am happy with the product performance. I put in a new estimated 240sq ft plywood roofdeck. I bought the seal tape and elasto barrier, and the roofing fabric. Seal tape review, takeaway is it works well, but the 6 inch is hard to work with. The inch tape is MUCH easier to work with. Lessons learned, use smaller sections of the 6inch tape so that it doesn’t fold onto itself and ruin the entire piece. Elasto barrier review, I put down a liberal first coat directly onto the clean, dry plywood. This coat has been my saving grace to this point. Lessons learned. Apply the first coat liberally under direct sunlight. Roofing fabric review, For the next step I tried to embed the roofing fabric as seen in a few videos online. I realized a few key points after I experienced some hardships. Takeaways, If doing this alone, cut the roofing fabric in half to make it easier to use. Two, make sure the coat of elasto barrier you put underneath the fabric to embed it is liberal and does not miss any areas the fabric touches. Three, DO NOT allow any wrinkles or bubbles. My final steps have been and will be, elasto barrier the cut-out bubble holes. Let the patches cure for 1.5 days in sun and double-check for any more bubble patches I have missed. Next, I will apply final liberal topcoat of elasto barrier to whole roof. Let cure. Top coat with safe t deck. Overall I am happy with the product performance, although the roofing fabric application could have been a better experience if I had known the dire importance of these few things I mentioned above. Live and learn and hopefully this deck will still turn out nice. Hope this helps another serious DIYer.

    Good stuff. I used this under the Maximum stretch and it has been 10 years in the southern sun, and I have my first leak. I am going to order some maximum stretch and recoat. It was recommended to recoat in 5 years so lasting 10 was good service.

    We tried all kinds of products to seal our deck. This one worked and lasted well over 10 years. Apply as instructed with a base coat, then the mesh then extra base coats to cover the mesh and finally the UV protection. We applied an added coat after 5 years and it still was shedding water with no cracking after 15 years when we moved.

    Once upon a time, I had a leak on my upper deck that covers my lower patio area. So desperate to stop the leak, I was hoodwinked into buying products like Flex Seal and other tarred materials. Those products did not stop my leak. It wasn’t until I used your products the Super Elasto Barrier followed by the Maximum Stretch, I was able to stop the leak. I waited several months after the initial use to provide this feedback because I wanted to be sure your product worked. Well, here in the Dallas Metro Area we have had several tornado like rains and my deck does not leak. I will not hesitate to recommend your product particularly the Maximum Stretch to anyone. Keep up the good work, take care.
