Jarrah Oil In response to requests for a water-based coating for export timber products, TIMBACHEM have developed Jarrah Oil . This product is based on a drying oil and application equipment may be washed out with warm, soapy water. It is ideal for large areas such as decking, fences, weather board and gates. It may be also be used on furniture and joinery. Jarrah Oil is also sold as by Jensen Jarrah as "Jarrah ColourGuard Plus". The two products are identical.


Timber surfaces should be dry, clean and free from paint, varnish or other non-porous coatings. Jarrah Oil should be applied straight from the can using brush, spray or roller. Jarrah Oil may be used on green (unseasoned) timber, however seasoning faults may lead to surface degradation.

Excess product should be wiped off approximately 5 minutes after application with a clean, lint free cloth.

This is most important!

If Jarrah Oil is allowed to "pool", or is too thickly applied, long drying times may result. The product should be "rubbed into" the timber.

One or two coats are recommended for optimum exterior results.

Recoating Time: 24 - 36 hours.

Drying Time: 1 to 2 days.

Clean up with water.

Jarrah Oil may be used on any species of timber however trials should be conducted when a previously untried timber is to be coated.

Coverage: 15-20 square metres per litre depending upon method of application and texture and porosity of timber surface. For optimum performance tinting and/or thinning is not recommended.

Jarrah Oil is available in 1 litre, 4 litre, and 20 litre containers.


Jarrah Oil and ColourGuard treated timber should be re-coated on a regular basis. In the worst possible case, i.e. north facing and totally exposed, the products should last at least one season. South-facing, sheltered surfaces should last up to five years.

Re-coating is simple:

  • Wash the surface down to remove dirt.
  • Allow to dry. Recoating is best done in warm weather.
  • Apply one or two coats of the same type of the product that was originally used.

If the surface of the timber has seriously degraded, as evidenced by greying and checking, a light sanding is recommended to freshen up the timber.

Hint: If your Colourguard treated timber has become dull and dirty but not weathered, spruce it up with our Orange Oil!
