Should I apply adhesive under boards?
- Yes – apply exterior quality adhesive (Bostik Ultra Set Polyurethane) this also serves as an acoustic membrane between the floor joist and the decking boards.
- Specifically (a polyurethane adhesive) supplied under several brands. We recommend Bostik Ultra Set SF as the product comes with the manufacturers specification for this application.
- This process is part of the Deck-Max™ proprietary system and is included in each kit – however we always recommend to buy some extra cartridges as we seem to use more than what is included. E.g. in a Kit No. 30 you will receive 4 x 300ml cartridges – buy one extra.
- Apply adhesive into the lateral cut and on the butt joints and mitred corners on final assembly.
