Characteristics of Wood Preservatives - NatureWood

The NatureWood wood preservative is a waterborne, alkaline copper quaternary preservative systems developed to provide long-term protection of wood exposed in exterior applications. The NatureWood system is based on the well-established effectiveness of copper combined with an organic quaternary compound and is applied to wood by pressure treatment. Copper and quaternary compounds are effective fungicides and termiticides. Together they provide protection from a broad spectrum of fungi and termites. Quaternary compounds are commonly used as swimming pool additives, disinfectants and sanitizers and have antibacterial properties.

Properly treated and processed NatureWood products are similar to CCA treated wood products - both are pressure treated, long lasting, durable, clean to the touch and have no objectionable odor. More than a decade of field test performance and commercial use worldwide establishes the proven effectiveness of the NatureWood preservative technology against termites and fungal decay.

Freshly treated NatureWood products begin with a familiar greenish color and will over time turn to a light tan/brown color upon exposure to sunlight. As with outdoor wood products, NatureWood products will eventually fade to gray over time. The preservative technology in NatureWood products is registered by EPA as a non-restricted pesticide and does not require Proposition 65 labeling in California. NatureWood products as described in National Evaluation Report - NER# 628, meets all major model building code requirements.

Important Information

  • Do not burn preserved wood. (see Disposal section)
  • Wear dust mask and goggles when cutting and handling wood.
  • Wear gloves when working with wood.
  • All sawdust and construction debris should be cleaned up and disposed of after construction.
  • Some preservative may migrated into soil/water or dislodge from the wood. Incidental contact with skin during construction or use may occur.
  • After working with the wood wash exposed areas thoroughly.
  • Wash work clothes separately from other household clothing before reuse.
  • Preserved wood should not be used where it may come into direct or indirect contact with drinking water, except for used 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.
  • Do not use preserved wood for mulch.
  • Only preserved wood that is visibly clean and free of surface residue should be used for patios, decks, and walkways.
