ACQ Preservative Protection
ACQ treated wood is a copper plus quat system that provides the same level of protection to wood as CCA preservatives against decay, rot and termite attack without the use of arsenic and chromium. ACQ treated wood does not contain any California Prop. 65 or EPA-listed hazardous chemicals.

The main active ingredient in ACQ is copper, which has long been established as the most cost effective preservative component used in timber preservation. Quat acts as the co-biocide in the ACQ preservative, providing additional protection from fungi and insect attack that copper alone would not control. Quats are commonly used in household and industrial disinfectants and cleaners and are biodegradable in soil. Copper and quat solutions similar to ACQ are used for the control of fungi and bacteria in swimming pools and spas.

Applications
ACQ can be used for any construction project and is particularly suited for applications such as decking, playgrounds, walkways, benches, outdoor tables and chairs, fencing, gazebos and landscaping, where long-term protection against decay and termites is a priority.
 
 
Nails, Fasteners and Fittings
For the best results, hot dipped galvanized or stainless steel fasteners and fittings are recommended. These are the same fasteners recommended for CCA-treated wood and specified for use with treated wood by major building codes. A list of manufacturers that recommend the use of their fasteners with ACQ® is available from your supplier or at www.treatedwood.com. Direct contact of ACQ treated wood with aluminum fasteners and fittings is not recommended.
 
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 enhance the long-term weathering performance. It is important that the wood is dry and free from surface deposits prior to applying any coating. 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.
 
Handling and Safety Information
ACQ pressure-treated wood is easy to work with, requiring no special precautions other than routine wood working safety procedures. When working with or machining, the following safety precautions should be followed:
  • Gloves should be worn to protect against splinters and abrasions.
  • A dust mask should be worn when machining any wood to reduce the inhalation of wood dusts.
  • Appropriate eye protection should be worn to reduce the potential for eye injury from wood dust or particles and flying debris during machining and construction.
  • Wash thoroughly with mild soap and water after working with any treated wood product.
  • Wood scraps should be disposed of by burial in accordance with applicable federal, state and local regulations. Do not burn treated wood product.
