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 Fitting

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.

Decay & Termite Protection

Wood used in outdoor environments and in high moisture conditions, is susceptible to attack from decay fungi and termites that can cause strength reduction and eventual failure of wooden structures. Preserve® pressure treated wood products are ideal for use in a wide range of applications where protection from biological degradation is required.

Safety & Handling

Preserve® pressure-treated products do not contain any California Prop. 65 chemicals or EPA-listed hazardous chemicals and are easy to work with, requiring no special precautions other than routine wood working safety procedures. When working with or machining Preserve® pressure-treated wood, the following safety precautions should be followed:

  • Wear a dust mask and goggles when cutting or handling treated or untreated wood.
  • Wear gloves when working with treated or untreated wood.
  • After working with wood, wash exposed areas thoroughly.
  • Do not burn pressure-treated wood.
  • Wash work clothes separately from other household clothing before reuse.
  • Pressure-treated wood should not be used where it may come into direct or indirect contact with drinking water, except for uses involving incidental contact such as fresh water docks and bridges.
  • Do not use pressure-treated wood in circumstances where the preservative may become a component of food, animal feed, or beehives.
  • Do not use pressure-treated wood for mulch.
  • ACQ treated wood scraps and cut offs should be disposed of in a non-hazardous material lined landfill in accordance with local, state and federal regulations.
