Decking oils are highly resistant to water and dirt, making them an ideal protective finish for all kinds of wooden decks.

A range of decking oil formulations and brands are available, so you’ll have plenty of options to choose from. Below is our pick for the best decking oils available in Australia to protect your deck from sun damage, water damage, and more. We’ve also included a helpful buyer’s guide so that you can choose the best decking oil for a beautiful and long-lasting finish.

Decking Oil Buyer’s Guide


Now that you’ve seen some of the best decking oil options, here’s a buyer’s guide to answer some of your questions.

Water-Based vs Oil Based Products

Decking oils can be either water-based or oil-based. While water-based oil formulas are newer, they seem to be just as effective as traditional oil-based formulas. Oil-based products are known to penetrate deeply and provide moisture resistance, whereas water-based formulas are usually fungus and mould resistant.

Both options will work well, depending on your deck type, the age of your wood, and what properties matter most to you personally.

Deck Oiling Coats

Most decking oil should be applied in at least two coats. Even though there are a few one coat products available, we highly recommend opting for at least two coats.

As always, read the instructions on any product you buy and follow them. Generally, though, you can expect to apply two coats to achieve fresh and well-oiled looking results.

Application and Drying Time

To apply decking oil, you will need to use a brush or lambswool applicator. It’s best to have an applicator with a long sturdy handle accessible so that you can evenly coat those hard to reach areas. You’ll paint each coat onto wood using smooth and even strokes. Just like with paint, it’s important to wait for each layer to dry completely before applying a new one.

Unlike paint, decking oil gets absorbed deeply into the surface of the wood. So, after the first coat dries, it’s best to wait twice as long before adding the second coat. The same goes for adding a third coat. This is very important, as applying a second or third coat too quickly can cause blotches, streaks, and pooling. To get the best possible results, you might even consider waiting a couple days after the second coat before applying a third.
