Treatment is carried out by impregnation of the timber, under pressure with CCA/ACQ preservative in accordance with Australian Standards 1604.1 - 2005.

Why Treat Timber?

Preservative treatment of pine provides long-term protection from decay fungi and termites that can attack and destroy untreated non-durable timbers. The use of treated pine for outdoor projects extends the service life of the structure through the improved durability of the timber itself. This maximises the efficient use of our pine plantation resource while reducing replacement and maintenance costs.

Is Pine a Renewable Resource?

Davids Timber has a vested interest in ensuring there are more pine trees in the future, not less. All products produced by Davids Timber are supplied from a renewable resource - plantation grown pine, harvested from well-managed forests on a sustainable yield basis.

How to Safely use Treated Timber.

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.

Safety Precautions.

Wear gloves to help avoid splinters.
Cuts and abrasions should be protected from sawdust whilst sawing or machining timber.
Wash hands and face free of sawdust before meals or smoking. Food and drink should not be left exposed to wood dust.
When sawing and machining treated wood, wear a dust mask. Whenever possible, these operations should be performed outdoors to avoid indoor accumulations of sawdust.
When power sawing and machining, wear goggles to protect eyes from flying particles.
Sanding operations should be performed in well-ventilated areas. If this is not feasible, use dust protection equipment. A dust mask and goggles will generally suffice. Gloves and overalls in high dust situations are also recommended.
Avoid handling or machining freshly treated wet timber.

How should I dispose of treated timber?

Treated timber waste and off-cuts must not be burned in barbeques, fireplaces, wood burning stoves or in any confined spaces. Toxic fumes may be produced and preservative residues may be left in the ash. These could pose health or environmental concerns.
The best method of disposal for normal trade and domestic users is by your normal garbage collection services. Treated timber should not be left where other people may collect it for firewood.

How to Paint & Stain Treated Timber?

Treated timber can be left in it's original form, painted or stained to suit individual preferences. Always ensure that treated timber is dry prior to applying stains, paints or coatings.

Clear water-repellent stains and paints should be applied to timber used in an external applications. We recommend the use of a water resistant stain. These applications will extend the life of external timber products.

How does Treated Timber Weather?

Treated timber will weather naturally when exposed to the elements, eventually from its pale green colour to a pleasing driftwood grey. All timber exposed to the outdoors will have a natural tendency to warp, twist, cup and split due to the properties of the timber itself and the action of mechanical weathering caused by rain, wind and sun.

What are the Hazard Levels?

The treated pine produced by Davids Timber is treated to specific preservative loadings in accordance with Australian Standard 1604.1 - 2005. Above ground applications exposed to the elements require a preservative loading classified as H3. Ground contact applications are more severe and require preservative treatment to higher H-4, H-5 and H-6 loadings.
