How to use Universal Wood Preserver

  • Open up and make accessible as much timber surface as is practical; e.g. lift some floorboards to gain access to both top and bottom surfaces of floorboards and to flooring joists.
  • Ensure all wooden surfaces are clean and free from dust and other conta­mina­tion
  • Apply to all accessible surfaces of the timbers at the applicable coverage rates using either brush or low-pressure spray unit to provide lasting protection from wood rot and insect infestation,

  • Drying: Subject to timber and ambient conditions the product is touch dry after 1 hour and should be suitable for overpa­inting, varnishing or staining after 24 hours.
