How to use this product

Avoid contact with skin and eyes.
Surfaces to be bonded should be free of oil, grease and dust. On wet timber pooled water should be wiped off. Cut cartridge tip, fit nozzle and cut end to desired opening. (Approx 5 mm diameter).


  • Direct a bead along the length of the joist, stud or batten. On broad flat surfaces apply beads every 40 cm. (‘zig-zag’ beads are more appropriate on surfaces of moderate width; eg shiplap panels.)
  • Fix with sufficient nails, screws or clamping to hold load and achieve contact over the total bond area. Wet bonds are repositionable for up to 15 mins after fitting.
  • Allow adhesives to set (at least 8 hours) before removing any temporary fasteners or clamping.(Refer to Bond Strength Time.)

CONTACT BOND METHOD – for faster grab

  • Apply a bead to one surface only, press together and pull apart.
  • Allow surfaces to dry 2-4 minutes before firmly joining. Surfaces should not be kept apart for longer than 10 minutes as to do so will impair bond strength

When fixing sheet flooring (e.g. particleboard), use in conjunction with flooring manufacturer’s installation specifications for minimum nailing requirements. Note: To eliminate squeaks in tongue and groove flooring, use Liquid Nails Heavy Duty in conjunction with mechanical fixings.

Handy tips

  • Time for strong bond depends on nature and condition of application. In most situations^ strong bond can be achieved after 8 hours and will continue to strengthen over a 2-3 day period. Full cure can take up to 7 days.

^Curing is achieved by evaporation of solvent. The time required to achieve the bond’s full strength is increased by: constant low temperatures; thick applications (joints) are used; wide areas are bonded; and when bonded surfaces are impervious (e.g. metals and dense timbers).
