What is Ames® Maximum-Stretch® Liquid Rubber Roof Coating?
A thick, high premium grade quality rubber & acrylic elastomeric coating, Ames® Maximum-Stretch® is a top elastomeric roof sealant product from Ames Research Laboratories, Inc. It is designed for maintaining and waterproofing many different types of roofing systems. Changes and temperature as well as extreme weather cause expansion and contraction in roofing and will result in cracks and leaks over time. Maximum-Stretch® is an up to 750% elastomeric roof sealant and remains flexible at freezing temperatures. Available in three colors at no extra charge, also tintable. See store color charts.

Ready to use – no mixing required. Powerwash and clean the surface. Remove all loose paint, dirt, oil and grease leaving surface clean and completely dry. Do not use any soaps, detergents, or cleaners whatsoever to clean surface. 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. As an option, use Ames® Peel & Stick™ adhesive seam tape and tape all joints, seams and around vents. Call for specific instructions 888-345-0809.
Pour the thick liquid coating out and spread 1-2 gallons of product liberally with a push roller or broom. Work the product until it is smooth and looks consistent in thickness. Move on after a few minutes so the product does not skin over or form a film which can create an unintended texture in the coating’s finished appearance. In most instances, the minimum application is two coats at a rate of one gallon per 100 sq. ft. per coat.
Ames® Maximum-Stretch® 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 may need Ames® Peel & Stick™ Seam Tape and scissors or a utility knife. For larger commercial jobs, we recommend a commercial/industrial airless sprayer. Call toll free for sprayer specifications and information at 1-888-345-0809.
Standard product coverage on a smooth surface is 100 sq. ft. per gallon per coat. Rough or uneven surfaces may require additional product. More than one coat is recommended. More coats equal longer life.
Weather & Drying Guidelines:
Ames’® Maximum-Stretch® is best applied between 50° to 90° F (10° to 32° C) on warm and dry surfaces. Apply when the streets are dry, the sun is in the sky and no inclement weather is forecast. Starts to dry in about 2-8 hours, depending on thickness of application and weather; if at all possible, for best results, we recommend a minimum of 24 hours between coats. No rain in the forecast and no freezing temperatures. Low temperatures, high humidity and evening and morning dew will require increased drying/curing time. Do not apply after 3 pm for best drying. The earlier you can put it on, the better. Make sure any morning dew is completely dried off before proceeding.
Clean-up, Storage, and Disposal:
Clean tools and small spills with water. Store unused product in its original container, tightly sealed and protect from freezing. Dispose of this product in accordance with local, state, or federal requirements.
