Black Diamond

Product Description

Black Diamond™ is GemSeal’s new, high performance alternative to asphalt emulsion (AE) sealer and refined tar sealer.

With all the environmental benefits of AE sealer, Black Diamond exceeds AE performance with longer durability, increased toughness against power steering marks, and stays black. Black Diamond also provides performance similar to refined tar sealer’s fuel resistance, durability, and ease of application.

Finally, like all GemSeal pavement sealers, Black Diamond is manufactured with our precision colloid mill system, providing a product that will always be consistent and backed by our nationally recognized quality assurance program.

  • Tougher – resists power steering marks
  • Water based Low VOC – less than 100 grams per liter
  • Easy to apply – applies as smoothly as refined tar sealers
  • Burn free – crews will love to work with it!
  • Temperature friendly – can be applied in lower temperatures than AE sealers
  • Weatherproof – seals out damaging effects of water and oil, extending the life of asphalt pavement
