About GAF Elastuff® 103 Roof Coating

GAF Elastuff® 103 Roof Coating, when used with Elastuff® 101 Base Coat, creates a roof coating system that provides an excellent balance of tensile strength, elongation, and hardness, along with excellent durability, dirt and mildew resistance, chemical resistance, weatherproofing, and high abrasion and impact resistance (formerly known as United Coatings™ Elastuff® 103 Roof Coating).

  • Elastuff® 103 Roof Coating is particularly effective as a protective membrane over new or existing roof substrates, including concrete, metal, polyurethane foam, and asphaltic substrates.
  • Also effective when used on other horizontal or vertical applications requiring a tough, abrasion- and chemical-resistant membrane, such as secondary containment and hot or ambient storage tanks
  • Very effective when used on its own in a wide variety of applications requiring a tough, abrasion-resistant finish
