Jarrah
Jarrah (Eucalyptus marginata) is one of over 500 different species of eucalyptus trees and grows only in southwestern Australia. The jarrah tree has a diameter of 1–1.5m and a height of 30–45m. Of the wood, only the heartwood is normally used, which is dark red, but darkens further in light, and resembles mahogany (hence the name “Australian mahogany”). The wood, which is heavy, hard and strong and very resistant to rot and insects, is used in Australia for, among other things, flooring, outdoor joinery and railway sleepers. In Europe it is imported as an alternative to wood from tropical rainforests.
It has been used in many construction situations where high demands are placed on strength and durability. The piers in Perth Harbour are an example and in the London Underground system where sleepers are still in place after 130 years. Unlike many other hardwoods, Jarrah is relatively fast-growing. It takes about 65 years from plantation to harvest. This enables Jarrah forestry that is both economically and ecologically sustainable. The trees are grown and harvested under the control of the government agency CLAM (Department of Conservation and Management).
Your Jarrah furniture
Like all untreated outdoor furniture, your Jarrah furniture should be regularly oiled with the recommended oil to maintain its original red luster and prevent deeper cracks. However, changes in temperature and humidity affect all wood, including Jarrah. Cracks may appear on the surface. This has no effect on the durability of the wood and is therefore not to be considered a defect. If treatment is not carried out for a long time, the luster and colour of the wooden surface will dull. If this is the case, you can still restore your furniture to its original colour, see below. However, please note that the furniture will develop more cracks, especially in sensitive areas such as end wood. If this is the case, you can order spare parts.
Reddish brown luster
Oil your Jarrah furniture with a special thin Jarrah oil before you take it out, then you will get a reddish-brown luster. Tip!: Use a plant sprayer to apply the oil, spray the underside as well. Wipe with a cloth. Polish a fine surface with a dry cloth after the oil has dried. If a fatter oil was used, more polishing is needed to achieve a fine surface. Before using a "own" oil, first test how it affects your furniture. Color deviations have occurred with other oils. Repeat the treatment once, 2, 3 times a year or when you see when the furniture becomes dry. When oiling for the second time, oil the furniture, sand lightly with sandpaper grain size 180, before the oil has dried. Wipe with another cloth, let the oil dry, polish a fine surface. this should be done once a year. Note that you can always make the furniture look like new in luster even after 10 years. You then need to sand thoroughly with a machine and then oil the furniture, sand lightly with 180 grit sandpaper before the oil has dried. Wipe with a cloth, let the oil dry, and polish to a fine surface.
Warm silver gray
If you want your furniture to be warm, you should go for a silvery gray.
Oil the furniture before you put it in place, the wood should be well saturated. After that, the elements of the weather will patina your furniture to a warm silver-gray color. It can take up to 5 years. If you regret it, just sand thoroughly with a machine and then oil the furniture, sand lightly with sandpaper grain size 180 before the oil has dried. Wipe with a cloth, let the oil dry, polish a fine surface and the furniture will regain its reddish-brown luster.
Warning! Rags with oil can ignite spontaneously!
