Treated Pine Description
Radiata pine is a softwood. It grows up to ten times faster than eucalypts. Its timber is creamy yellow, with distinct growth rings. The grain is straight and carpenters easily work it, making it a timber with low natural durability. Radiata Pine is grown in plantations in most states of Australia.
Working with CCA Treated Timber
CCA treated timber can be planed, 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.
All end cuts, rebates, drill holes and notches should be resealed with an approved “in can” timber protective such as Protim Re-seal.
You will never regret the small additional cost of taking these steps when you appreciate the long term benefits of durable outdoor structures using tantalised treated timber.
Good building practices should always be utilised in the application of treated pine to ensure maximum stability and endurance.
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 any wood dust.
Follow the same normal standard safety practices associated with working with any sort of timber.
* When sawing and machining, 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.
Domestic users should dispose of off-cuts and redundant pieces through normal waste collection services. Trade or industrial manufacturers generating larger volumes of treated wood waste may require approval from their local waste services authority or council.
Treated timber should not be burnt as a means of disposal or left where other people may collect it for firewood.
Painting, Staining, Weathering
CCA treated can be left in its original form or painted or stained to suit individual preferences. Always ensure that treated pine is dry and dust free prior to applying all stains, paints or coatings.
How does treated timber weather
CCA 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.
We recommend you apply a clear water-repellent stain such as Protim Raincoat or paint to timber used in an external application. These products will extend the life of all external timber products.
