How To Use

Do not swallow. Use in a well ventilated area. Avoid contact with skin and eyes. Pierce foil seal before inserting into caulking gun.

  1. Ensure surfaces are dry and free from oil, grease and dust. Wipe off any pooled water from wet timber.
  2. Cut cartridge tip and pierce foil, attach nozzle and cut to size (5mm), then insert into caulking gun.
  3. Apply Liquid Nails with a  zig zag pattern along the adhesion area.
  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.

Handy Tips

  • *Usually mechanical fasteners are required for only 8 hours on porous surfaces and a strong bond is achieved in 24 hours and continues to strengthen over 2-3 days. Cures in 7 days. Expect longer times for thicker applications, less porous surfaces and in cold weather.
  • Adheres to wet/poor seasoned timber.
  • Bridges gaps up to 9mm.
  • Paintable after 24 hours.

Clean Up

  • Uncured product may be removed with mineral turpentine.
  • Cured product can be removed by scraping or sanding.
