• Carefully clean the hole as required by the manufacturer. It is crucial to follow the manufacturers instructions:
  • Some specify cleaning hole with water
  • Some specify absolutely no water should be in hole
  • The hole must be properly brushed and blown out prior to adhesive installation.
  • Note the use of a nylon brush for cleaning the hole.
  • A steel brush should not be used as it leaves metal particles in the hole
