Painting and Staining or Natural Weathering

ACQ 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, ACQ 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 acceptable for use with ACQ treated wood. Direct contact of Preserve treated wood with aluminum fasteners and fittings is not recommended.
