WHY USE MACROCARPA TIMBER?
Macropcarpa is a great enviro-friendly alternative to treated timber. It is naturally durable because it has natural oils that deter insects and fungal growth. So it can be used without having to resort to the toxic trio of copper, chromium and arsenic (chromated copper arsenate or CCA) with which radiata is treated to achieve the same durability. Macrocarpa has very good dimensional stability—better than radiata which means it will swell and shrink less in response to atmospheric humidity. Above ground the heartwood timber should be sound for 20 to 30 years (macrocarpa has very little sapwood).
PAINT OR STAIN, WHAT WORKS BETTER?
Macrocarpa has a fine grain and machines and sands well to give a high-quality finish. When dry, macrocarpa will accept a variety of paints, oils, two pot resins and varnishes. For exposed areas it is best to stain. The advantage is that it does not peel and can then be re-stained without much treatment. Painting is okay for sheltered areas. Keep in mind to re-paint before the paints starts cracking or peeling. You can also leave the timber bare – the timber will get a nice silvery / grey look over time and it can still be stained later if you wish.
The recommendation for pine is to follow the manufacturer’s instructions and label of the finishing product, If you desire to apply a paint, stain, clear water repellent, or other finish to your preservative treated timber. Before you start, we recommend you apply the finishing product to a small exposed test area before finishing the entire project to insure it provides the intended result before proceeding.
