Seal Coat Information

Seal Coat - Gem Seal Black Diamond AE  
  • 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. Gem Seal Black Diamond Products

How long should you stay off the driveway?
  • We urge everyone to stay off the pavement for at least 24 hours on a good hot summer day. If your driveway is shaded it can take longer to dry. To be safe, allow 48 hours before driving on the pavement. It may look dry but it will not be fully cured for quite some time. Should you drive on the pavement and damage the coat, you will have to pay for us to reseal the pavement.
