John Carroll (above) joined the family business after he finished high school in the seventies and is still working in the family timber business more than 45 years later.

ACQ Treatment

ACQ Treatment Process

alkaline copper quaternary (ACQ) is a wood preservative method recently adopted by countries such as Australia, Canada and the U.S where the need for an alternative to chromated copper arsenate exists. Composed of a quaternary ammonium compound, a fungicide, a bactericide and copper, ACQ makes treated wood resistant to all forms of biological attack, including insects and natural decay.

Benefits of ACQ Treatment

  • Suitable for use in environmentally sensitive regions
  • Offers long-term protection against fungal rot, damage due to high moisture conditions and destruction by wood-boring organisms
  • Gradually weathers to a rich, honey colour
  • Can be easily stained or painted
  • Industry-recognised QA systems ensure quality control of ACQ application at timber treatment plants
  • Treated wood scraps can be safely thrown into typical rubbish collections
  • Specially suited for use on retaining walls, outdoor chairs and tables, walkways, gazebos, decking, benches, landscaping and domestic and agricultural fencing

Environmentally Safe and Effective as a Wood Preservative

For those who are concerned about other treatments, ACQ and its primary ingredient copper does not pose any kind of risk to the environment or to humans. Copper in ACQ is combined with “quat”, or a quaternary compound co-biocide that dramatically improves treated woods’ resistance against copper-tolerant insects and fungi. “Quats” are also found in many “green” household cleaners and disinfectants.

ACQ Treated Wood and Metal Fasteners

Wood that has been treated with ACQ will expedite corrosion and degradation of metal fasteners relative to wood that is not treated with ACQ. Consequently, other types of steel fasteners must be incorporated with ACQ treated wood, such as stainless steel, copper or hot-dipped galvanized steel fasteners.
