Treated H3 Pine timber is designed for long-term protection against termite attack, rot, decay and weather for more than 30 years in above ground outdoor applications. Treated timber enhances its durability in exposed conditions, making it ideal for Australian conditions. Porta uses clear knot-free pine that is easy to cut, nail and glue.
Porta's Treated H3 Pine is impregnated with copper fixed ACQ (Alkaline Copper Quaternary) waterborne preservatives that increases the timbers service life and durability for 30+ years. It is a safe, user friendly, preservative that complies with Australian Standard AS1604. H3 Treated Pine uses Select grade Pine. Porta grades Pine timber according to the Australian standard AS 4785.2 - 2006. Select grade features very few marks and natural characteristics, making it a stronger, cleaner and more versatile timber.
Treated H3 Pine will initially have a greenish appearance that will eventually weather to a honey brown before fading to a lustrous grey after exposure to wind, rain and sun.
Treated Pine is very easy to work with standard tools. Its low density means it holds nails and screws very well. It can be successfully stained, painted, waxed or colour-washed. Its open grain structure readily accepts preservative treatment. If modifying the original dimension of the treated timber, you may expose untreated heartwood (inner timber). If so, please apply a brush-on or spray-on preservative to all cut-ends or planed surfaces.
What timber can I use outdoors?
Porta has a number of timbers suitable for outdoor applications including Cumaru, Karri, Jarrah and H3 Treated Pine. It is important to determine whether the application is for above ground or inground as the durability class of the timber will determine its suitability. Porta's moulding range includes H3 Treated Pine which is suitable for above-ground exterior applications, having a natural durability class of 30 years above-ground. Hardwood such as our Tasmanian Oak timber is also suitable with a natural durability class of 7-15 years above-ground.For more information and FAQ visit Our Timber page.
How do I store and care for H3 Treated Pine?
Store boards on a rigid, smooth, flat surface. Boards should be kept covered from direct sunlight, well ventilated and adequately supported. To care for H3 Treated Pine we recommended a clear or tinted oil-based water-repellent coating be applied, either timber stain or paint preparation to all faces and edges.
Do I need to use a special type of fastener with H3 Treated Pine?
Yes, only use recommended hot dipped galvanised or stainless steel fasteners.
Is Porta's Pine treated with any chemicals?
Porta Pine is conditioned with potable town water to stabilise the fibre. No chemicals or treatments are used in the production process. It is exclusively made from timbers sourced from independantly certified, sustainable and renewable forest plantation operations. Porta Treated Pine is treated with ACQ process which is based on a Copper preservative.
Can Porta's treated pine be used for a pet kennel or externally?
Yes, it can be used for a pet kennel or external projects. It is treated with a fixed waterborne copper preservative, known as Alkaline Copper Quaternary (ACQ). This protects against rot, decay, UV and weathering. Any chemical treatment may irritate the skin and it is advisable to seal all surfaces with an acrylic or urethane coating.
