Tar & Gravel Roof

Application Instructions

Ames® 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. 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. 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. 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.

Estimated Coverage:
The minimum application of Elasto-Barrier®  is 3 gallons per 100 sq. ft. and Maximum-Stretch® is 2 gallons per 100 sq. ft. for each 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.

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.
