Post Treatment Handling Guidelines.

 Ensuring on-going protection of treated timber:

  • Any surface exposed by drilling or cutting must be retreated with a cut end preservative (available from Glenavon in 2.5 and 5 litre containers). Failure to retreat will reduce the effectiveness of the preservative.
  • It is recommended that the re-preserved ends are not put in the ground or in direct contact with water.
  • Rip-sawing, thicknessing and planing are not permitted unless the timber is subsequently re-treated to the original specification.
  • Preserved timber can be painted or stained once dry.
  • Preserved timber, once dry, can be glued with most commonly used adhesives.
  • When working with preserved timber, it is important that you use the right fixings to ensure the long-term future of your outdoor project. Use only hot-dipped galvanised, stainless steel or other approved Osmose fixings. Do not use Naturewood products in direct contact with aluminium.
  • Once fully dry, treated timber may be regarded as untreated for COSHH (Control of Substances Hazardous to Health Regulations 1994) purposes.


Safe Handling of treated timber:

  • Do not burn.
  • All sawdust and construction debris should be cleaned up and disposed of after construction.
  • Preserved wood should not be used where it may come into direct contact with drinking water, except for uses involving incidental contact such as fresh water docks and bridges.
  • Do not use preserved wood under circumstances where the preservative may become a component of food, animal feed or beehives.
  • Only preserved wood that is visibly clean and free of residue should be used for patios, decks and walkways.
