How To Choose the Right Oil for Your Timber
First things first: why do we oil? Timber is a natural material and a serious investment. Left unprotected, even the toughest wood can crack, grey, or warp under Australia’s brutal sun and unpredictable weather. That’s where regular oiling comes in.
Timber Is a Living Material
Unlike concrete or plastic, timber breathes. It expands, contracts, and reacts to moisture, heat, and sun. That natural movement means it needs protection from the elements without blocking it from breathing. Natural oils (like lanolin oils) nourish the wood without sealing it in plastic.
Oil = Nourishment, Not Just Protection
Timber oils like Deck Doc don’t just sit on top they penetrates deep into the wood grain. This prevents cracking, splitting, and drying out. It also repels water and reduces the risk of mould and rot. Finally, it enhances the natural beauty of the timber without changing its character.
Long-Term Savings
Replacing or repairing timber like timber decking or timber fencing is expensive. Regular maintenance with a quality oil protects your investment. A well-oiled timber deck lasts longer, looks better, and adds value to your home or rental property. Think of it like sunscreen for your timber - prevention is always cheaper than repair.
Now, how do you choose the right oil?
With so many products out there, it’s easy to feel overwhelmed so here’s what really matters.
Know Your Timber Type
Hardwoods (Spotted Gum, Merbau) are more dense and you have a greater flexibility of oil choice. Natural oils like lanolin oils are a great choice. You want to choose an oil that enhances their natural beauty while providing protection against the elements.
Softwoods (Treated Pine, Cypress) are more porous and soak up more oil. An oil-based product that offers good penetration is needed to achieve long-lasting protection. Softwoods may require a bit more TLC and additional treatments to increase their durability and resistance to moisture, decay, and pests.
Consider the Finish You Want
Want to keep that natural, matte look? Go for a clear timber oil that showcases the natural beauty of the timber. Want to restore a tired, greying deck? A tinted oil brings back warmth and depth.
Climate & Exposure Matter
If your deck gets hammered by sun and rain, you’ll need a product with staying power. Lanolin-based oils: repel water, reduce UV damage and stay flexible so timber can breathe.
