Use Interior
  1. Surface to be filled must be clean, dry and free from dust.
  2. Cut seal and nozzle to suit width of gap. Fit to cartridge. Insert into caulking gun such as Selleys Light Speed Caulking gun.
  3. Apply with caulking gun, forcing product into the gap.
  4. Press in and smooth off with a spatula. Take care not to drag out applied filler from the gap. Use spatula to scrape off as much residue as possible from the timber surface, to minimise sanding necessary.
  5. Clean up with a damp cloth immediately.
  6. Allow to dry for at least 24 hours before sanding off any residue from timber surface. Allow longer time in colder weather or if residue left on timber is excessive.
  7. Stain and varnish/paint as desired. Ensure stain/varnish is not allowed to pool in the joint – lightly wipe off while wet if necessary.
