Why customers choose TaskHolt Tools

Why choose Ames Maximum-Stretch

Ames Maximum-Stretch is a white elastomeric roof coating and sealant that blends rubberized resilience with acrylic flexibility. Its standout feature is up to 650% elongation, allowing it to move with the roof as temperatures shift, reducing the risk of cracking and peeling over time.

The bright white finish isn’t just cosmetic. With about 88% light reflectivity, the coating helps reflect a large share of the sun's energy away from the roof, potentially helping keep the surface cooler and contributing to lower cooling costs in hot climates.

Versatile adhesion for many roofs

Designed to adhere to a variety of substrates, including metal roofing, tar, and rolled roofs. Use it as an RV roof sealant, waterproof coating, or as a protective membrane for low-slope applications. The formula is a flexible, rubberized coating that moves with the roof.

  • 650% elongation to resist cracking and peeling
  • 88% light reflectivity with a bright white finish
  • Excellent adhesion to metal roofing, tar, and rolled roofs
  • Non-toxic, eco-friendly, low VOC, made in the USA

Easy to apply, versatile use

Apply by brush, roller, or spray for a flexible, user-friendly experience. Suitable for low-slope roof maintenance and as an RV roof sealant, waterproof coating, or rubber roofing membrane. Tintable white gives you color options for certain projects. Packaged in a 4.6-gallon container for larger jobs.

  • Brush, roll, or spray application for flexible use
  • Adheres to metal roofing, tar, and rolled roofs; ideal for low-slope surfaces
  • Tintable white option for color customization
  • Long-lasting seal with a 4.6-gallon pack
