If you need to glue foam boards together, the best choice is construction adhesive. It is designed to stand up to the weather and bonds well to common building materials. Here are some tips for installing it:

  3. Apply construction adhesive to the back of the board and the edges if appropriate. Run the adhesive in lines about 25cm apart.
  4. Press the board into position and secure it with screws or tape until the glue dries.
