Preserve® PLUS® CA
for Outdoor Wood Protection

(Wood Decay, Termites & Water Resistance)

Preserve® PLUS® logo

Sunbelt’s Preserve® PLUS® CA treatment protects wood against decay and termites is a wood preservative formulation made of soluble copper, combined with built-in water repellent protection. Preserve® PLUS® is suited for outdoor building projects in residential, commercial, and industrial applications where appearance is important and protection from the effects of weathering is a priority. It has water repellent plus CA preservative protection that is pressure treated deep to the heart of the wood, unlike brush-on applications that only protect the surface of the wood. This wood treatment provides long-lasting protection against the effects of weathering.

Painting and Staining or Natural Weathering

Preserve® PLUS® can be painted or stained to match any outdoor color scheme. High-quality oil-based paints and stains are recommended. Water repellent coatings can be applied to improve the long-term surface appearance of Preserve® PLUS®. Left uncoated or with clear water repellent coatings, this wood treatment 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

For the best results, the use of building-code-approved, corrosion-resistant fasteners, and connectors are always recommended.

Direct contact of Preserve treated wood with aluminum fasteners and fittings is not recommended.
