CCA treated timber has some limitations to its use within the Australian market. CCA treated timber cannot be used for garden furniture, picnic tables, exterior seating, children’s play equipment, patio and domestic decking and hand rails.
Alternative treatments such as MicroPro®, Naturewood® ACQ® and ProtimOptimum® are registered for use in these applications.
Koppers Performance Chemicals recommends these preservative options as suitable alternatives.
