Allowing the deck to weather for 2 to 4 months lets the timber bleed out all its natural oils and tannins. This process makes the deck much more receptive to coatings, treatments, and stains. Just be careful not to let it sit bare for too long, however, as over-weathering can have a negative effect on the timber.
Sanding is essential, as it removes any built-up dirt, mould, grime, or natural imperfections in the timber. A good-quality sand using a high-powered machine will ensure a pristine surface for applying timber coatings. It takes a bit of elbow grease, but it ensures a top-notch overall finish.
The final job before you can fire up the BBQ and enjoy your new deck is treating it. There are plenty of great treatments out there for timber decks, with the two main varieties being water-based and oil-based coatings. There are hundreds of different colour options available—from light oak to chocolate brown to weathered grey—so you should easily find one to suit your taste. Once you’ve decided on a treatment, get busy applying it; just make sure you pick a dry day! For more on this process, have a read of our dedicated coating blog.
