NatureWood© Pressure Treated Wood Products
About The Osmose NatureWood Preserved Wood Product
NatureWood preserved wood products offer termite and fungal decay protection similar to that of CCA treated wood. Ground contact testing of treated stakes confirms that while untreated SYP stakes fail in less than 5 years, stakes preserved with NatureWood preservatives perform similarly to CCA treated stakes.
Osmose NatureWood Preservative
The NatureWood® wood preservative is a waterborne, alkaline copper quaternary preservative system 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. The active ingredients, copper oxide and quaternary compounds, are dissolved in an alkaline carrier in NatureWood products.
Depending on the desired product application, wood species, and exposure hazard, the NatureWood preservative system may be formulated with a number of specialty additives such as water repellents to enhance product performance.

General Building Tips
When building outdoors with preserved wood, it's important to follow special construction practices, precautions, and maintenance procedures in order to get the most out of your finished product and protect it for years to come.
Most important, the project must be built safely and in accordance with state and local building codes. Before beginning your outdoor construction project using pressure treated wood, please make sure to review all building tips, consumer information, handling precautions, and care and maintenance recommendations.
When you choose pressure treated wood for your outdoor construction project, you'll want to be sure to follow quality craftsman guidelines for an excellent finished appearance and durability. Follow these helpful tips to make your project easier to build, last longer and look attractive.
When Appearance Permits, Nail Bark Side Up
As a general rule, nail boards bark side up (annual rings arc upwards) to reduce cupping. If a defect in the wood is noticeable, however, the best face should be placed up. Fasten thin boards to thicker boards to maintain structural integrity.
Drill Pilot Holes
To help minimize splitting of the wood, it's a good idea to drill pilot holes for your fasteners, especially when nailing near the edge or end of a board.
Deck Board Spacing
If the wood has been kiln dried or air dried after treatment (indicated by the word "Dry" on the end tag or stamp), it is not necessary to allow for shrinkage. However, if the wood has not been dried following treatment, some shrinkage can be expected. To allow for this, make sure to butt decking boards together.
Use an End Cut Preservative
Brush a wood preservative on all saw cuts and into drill holes during construction of wood projects. This is also recommended for any areas where moisture can collect.
After Care
There are many top quality maintenance products for your outdoor wood projects, including water repellents, stains, and cleaners. The finished product must be protected from moisture and sun damage.
