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.
