Copper Chrome Arsenate (CCA) water-borne preservative is by far the most widely used preservative for the treatment of pine timber. The first CCA product was developed in India by Dr. Sonti Kamassan in the 1930’s and it immediately started to take the place of many other timber preservatives used at the time. The copper acts as a fungicide while the arsenic is also an insecticide. Chrome is part of the formulation to fix the copper and arsenic.
CCA treated timber can be planned, chiselled, nailed or drilled just as easily as untreated timber. Carbide tipped saw blades are suggested when big projects are planned. Nails, plates and bolts should be hot-dip galvanized and/or stainless steel. Good building practices should always be utilised in the application of treated pine to ensure maximum stability and endurance.
CCA treated can be left in its original form or painted or stained to suit individual preferences. Always ensure that treated pine is dry to equilibrium with its intended end use environment prior to applying all stains, paints or coatings. CCA treated timber will weather naturally when exposed to the elements, eventually from its pale green colour to a pleasing driftwood grey.
