ACQ Timber Treatment
ACQ - Alkaline Copper Quaternary (ACQ) was developed as a safer alternative to CCA. While it is designed to be used as an insecticide and fungicide and is very similar to CCA in effectiveness, the main benefit to ACQ is that it does not contain any arsenic. While it is more expensive than CCA, ACQ is perfect for high-contact applications, such as garden furniture, children’s play equipment and exterior seating
