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.
