EternaBond® installations on built up roofs (asphalt, or coal tar).

When EternaBond® is installed to a built up surface, there is a series of steps that should be followed:

ETERNABOND®: WebSeal®, EternaPrime®.
OTHERS: Roof Coating of installer?s choice.

  1. Scrape back the gravel as much as possible.
  2. Whisk, broom, or blow off remaining dust and dirt. Do not wet the area trying to wash it.
  3. Treat the repair area with EternaPrime®. Allow it to dry completely.
  4. Apply WebSeal® over primed area. Rub aggressively so WebSeal® will conform to the roof surface and the gravel which is embedded in the roof and cannot be removed. If done correctly, the WebSeal® will wrap around each individual pebble!
  5. Coat the WebSeal® with the coating the installer has selected.
  6. Sweep the gravel back into place.
