I am planning on undertaking annual deck maintenance.
This is the first time I am doing the deck maintenance myself.
Looking for guidance on what is required (sanding, washing, etc).
The deck was installed brand new in March 2023 and this is the first maintenance since.
Not sure about what oil was used originally on the deck.
Hello @MSD
Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your questions about deck maintenance.
Undertaking your first deck maintenance is an excellent way to keep it looking great and well-protected. Since your deck is relatively new, you can approach the maintenance with less-intensive preparation. Start by giving it a thorough clean with a deck cleaning product like Cabot's Deck Clean. This will help remove dirt, grime, and any mould or mildew that may have developed. Use a stiff-bristled broom or brush to scrub the deck cleaner into the timber, then rinse it off with a pressure washer or hose, ensuring you don't use excessive pressure that might damage the wood.
Once the deck is clean and dry, inspect it for any rough or splintered areas. While a newly installed deck likely won’t need heavy sanding, a light sand with a fine-grit sanding sponge or paper, particularly on handrails or high-traffic spots, can ensure a smooth finish. After sanding, vacuum or sweep away dust to keep the surface clean for oiling or staining. There is no need to sand the entire deck, your goal is to smooth out any rough parts that might have splintered during the clean.
Finally, apply a decking oil or stain to nourish and protect the timber. I suggest having a look at this guide - How to oil your deck. Products like Cabot’s Aquadeck or Intergrain UltraDeck are popular choices, as they provide excellent protection while enhancing the natural beauty of the wood. Use a quality applicator, such as a deck brush or applicator pad, for an even finish. Follow the product instructions regarding drying times and apply a second coat if recommended.
If you need further assistance, please let us know.

Thanks Jacob. I did sand with a 120 grit. See attached pic. Does the sanding look ok?
Hi @MSD,
I wouldn't suggest using the belt sander on your deck as it doesn't need resurfacing. There are just some areas that look like the previous coating wasn't applied evenly. You could change to 80-grit in your detail sander, but I wouldn't push hard as you could scratch the timber. A belt sander is really a bit aggressive, and you risk damaging the timber.
I would scrub the deck down with Cabot's deck clean and see if it minimises the blotchy areas. If you were happy with the look of the deck before, then you've now improved it by sanding the areas. Give it a good scrub and you might like to post some images to check with us before coating.
