North America, Europe and Japan, to neighborhood playgrounds and
backyards like yours, Preserve treated wood has been used around
the globe to provide a durable building product for outdoor  projects where environmental
values and product safety are priorities. Northern Crossarm Co.

products of Arsenic-Free Pressure-Treated Wood using Preserve® treatment.

Painting
and Staining or Natural Weathering
Preserve can be painted or stained to match any outdoor color scheme.
High quality oil and latex-based paints and stains are recommended.
Water repellent coatings can be applied to improve the weathering
performance. Left uncoated or with clear water repellent coatings,
Preserve will initially weather to a natural brown color, eventually
turning gray following long-term exposure to the sun.
It is important to ensure that the wood is dry and free from surface
deposits prior to applying any coating.
Nails, Fasteners and Fittings
Hot-dipped galvanized or stainless steel fasteners and fittings
are recommended. Anti-corrosion coatings applied to fasteners and
fittings in contact with treated wood will enhance long-term performance.
Direct contact of Preserve treated wood with aluminum fasteners
and fittings is not recommended.
