Aussie Clear Decking Oil


AUSSIE CLEAR is an exterior decking oil and timber finish that protects hardwoods from the weather. It is the best oil-based finish to highlight the natural grain and beauty. This results in a completely natural oiled look. AUSSIE CLEAR stabilises timber as it repels moisture, reducing checking or splitting. No film is allowed to form, so peeling or cracking is never a problem. It also inhibits unsightly mould growth with its powerful mouldicide. It has been specially formulated and tinted to use on a broad range of hardwoods.

Recommended Uses

AUSSIE CLEAR can be used wherever a transparent oil-based exterior finish is required. This includes exterior decking, fencing, pergolas, weatherboards, window frames, furniture, cladding or facia. Timber finishes/decking oil such as AUSSIE CLEAR are suitable for all popular timbers including Cedar, Merbau, Jarrah, Cypress Pine, Spotted Gum etc. It has been formulated with its own “transparent” pigment to appear clear on darker hardwood timbers. Use Preschem TREATED PINE CLEAR on Treated Pine-based products.

Which product to use for darker and lighter timber

AUSSIE CLEAR is recommended for mid to dark-toned hardwoods such as Merbau, and Spotted Gum. AUSSIE CLEAR LIGHT is for blonde to mid-toned timber such as Blackbutt, Silvertop Ash, and Cypress Pine.

AUSSIE CLEAR and AUSSIE CLEAR LIGHT are Preschem’s range of decking oil for all hardwood timber. The philosophy behind this is that most hardwood timbers available in Australia are very similar in their properties. Even if their natural appearance is different. Thus a simple range of timber finishes will fit the bill.

Most people should be aware that the AUSSIE CLEAR range is lightly pigmented with a “transparent” pigment. This will appear “clear” on all mid to dark-toned timber, but the pigment will show up on blond or light-toned hardwood.

Correctly chose which version of our decking oil product to use it’s very simple. The original AUSSIE CLEAR should be used for mid to dark-toned timbers such as Spotted Gum, Jarrah, Ironbark, Redgum, and Merbau.

However, Aussie Clear is also suitable for Western Red Cedar, which is a softwood. For blondE to light-toned timbers such as Blackbutt, Yellow Stringybark and Cypress Pine, Aussie Clear Light should be used.

So what purpose does the pigment serve? There are three very good reasons for having a “transparent” pigment:

  1. The best UV protection is currently available. “Transparent” pigments offer superior performance in preventing grey weathering of exposed timber.
  2. Colour stability. As any decking oil ages, it will fade faster in some areas than others over time. This is due to timber being a natural product. The pigment evens the appearance while this happens.
  3. Restoring the natural colour. A timber deck that has been there for some time will have bled out all its natural colours. By adding pigment to timber finishes, it restores the natural colours*.

Directions For Use

Apply AUSSIE CLEAR to dry surfaces, free from dirt grease and wax. Previously varnished or painted surfaces must be thoroughly stripped. Badly weathered surfaces should be sanded back or cleaned using a wood cleaner such as Preschem’s GREY DECK CLEANER. It can be applied by any convenient means, such as brush, roller, spray or dip application. However, floors & decks are most easily applied with a lambswool applicator. Apply one coat of AUSSIE CLEAR, working it into the timber. Any excess oil, remaining on the surface after one hour should be wiped off. If the timber still looks dry, another application may be required. Allow 24 hours for thorough drying.


Timber treated with carefully formulated wood finishes such as the AUSSIE CLEAR decking oil, will not blacken when maintained regularly. However, over time and depending on the severity of exposure, the rich colour of the timber will fade. Repeat applications are simple as the timber can be re-oiled to bring back the rich natural timber texture.

Does Aussie Clear or Aussie Clear Light contain any tints?

Yes, both Aussie Clear and Aussie Clear Light are tinted with “clear” tints. They serve three important functions:

  1. To assist with maintaining the colour of the timber as the oil fades, for a more even and natural look
  2. Restore the natural “as new” timber colour when the natural timber pigments bleed out
  3. Offer the best possible protection against UV weathering

Aussie Clear is tinted to be “transparent” on mid to dark-toned timbers, whilst appearing a reddish-orange on light or “blonde” timber.

Aussie Clear Light is tinted for light-coloured or “blonde” hardwood timbers to appear like “wet straw”. Aussie Clear Light can also be used on mid to dark-toned hardwood timbers too.

Is Aussie Clear or Aussie Clear Light suitable for any hardwood species?

Yes, Aussie Clear and Aussie Clear Light are suitable for all hardwood species and also for Cedar (which is a softwood).

Note that Aussie Clear and Aussie Clear Light have different coloured pigments, so on mid to dark-toned hardwoods, either version of Aussie Clear will appear transparent. However, on blonde or light-coloured hardwoods, the pigment colour will be noticeable. Aussie Clear Light is the colour that most people will prefer on blonde-coloured timber as the finish will resemble “wet straw” in most instances.

Can I use Aussie Clear Oils without prepping with Grey deck cleaner?

Yes, if the deck has dark spots or showing any signs of greying, it’s best to apply Grey Deck Cleaner prior to using either Aussie Clear or Aussie Clear Light.
