Method of Application

  1. Substrates must be clean, dry, smooth, free of sharp edges, fins, loose or foreign materials, oil grease, and other materials which may damage the Uncured Flashing.
  2. All roughened surfaces which could damage the Uncured Flashing shall be repaired as specified to offer a smooth substrate.
  3. All surface voids greater than 1/4" wide shall be properly filled with an acceptable fill material.
  4. Install EPDM Uncured Flashing in accordance with current Royal Edge Specifications, Details and workmanship requirements.

Precautions

  1. Keep away from fire and ignition sources during storage and installation.
  2. Use of heat guns during cold weather will improve workability of flashing, but a wide nozzle should be used and care should be taken not to localize heat, as a hole in the flashing can result.
