  2. Cut cartridge tip and pierce foil, attach nozzle and cut to size (5mm), then insert into caulking gun.
  3. Apply bead along length of joist, stud or batten. On broad flat surfaces apply beads every 40cm.
  4. Position pieces and press firmly together. fix with sufficient nails, screws or clamping to hold load and achieve contact over total bond area. Repositionable for up to 20 minutes after fitting.
  5. Allow adhesive to set (minimum 8 hours) before removing any temporary fasteners or clamping. Use with mechanical fasteners in high stress applications.

Contact Bond Method
For immediate bond use contact bond method, apply to one surface only, press together and pull apart. Allow surfaces to dry 2-4 minutes, before firmly joining.

When fixing sheet flooring (e.g. particleboard), use in conjunction with flooring manufacturer’s installation specifications for minimum nailing requirements.
