    ACQ (alkaline copper quaternary) is a water-based wood preservative that prevents decay from fungi and insects (i.e. it is a fungicide and insecticide). It also has relatively low risks based on its components of copper oxide and quaternary ammonium compounds. Water-based preservatives like ACQ leave a dry paintable surface.
