What is the difference between deck sealing and deck oiling?

Deck sealing uses a film-forming product that creates a protective barrier on top of the timber surface, while deck oiling uses a penetrating oil that soaks into the timber grain. Sealers tend to last longer but can peel or crack over time, requiring more prep work to recoat. Oils are easier to maintain and allow the natural timber grain to show through. Sydney Deck recommends the best product for your specific timber species and usage.

How often should a deck be sealed in Sydney?

In Sydney's climate, timber decks typically need to be re-sealed every 2 to 3 years depending on sun exposure, foot traffic, and the type of sealer used. Decks with heavy UV exposure or close to the coast may need sealing more frequently. Doing the water bead test is the easiest way to know when it is time to reseal your deck.

How much does deck sealing cost in Sydney?

Deck sealing in Sydney costs between $20 and $45 per square metre depending on the size of the deck, its current condition, and the number of coats required. A standard 40 sqm deck seal costs approximately $800 to $1,800. Sydney Deck provides free on-site quotes with no hidden charges.

Does a deck need to be sanded before sealing?

Yes, if the old sealer or stain is peeling or worn, the deck should be sanded back to bare timber before applying a new sealer. If the existing sealer is still in good condition, a light clean and a fresh coat may be sufficient. Sydney Deck inspects every deck before recommending the right preparation and sealing process.

Can Sydney Deck seal my deck the same day as sanding?

In most cases, yes. Sydney Deck can sand and seal your deck in one visit for smaller jobs where the sanding is complete early in the day. For larger decks or in humid conditions, the first seal coat is applied the same day and the second coat the following day. We always ensure the timber is clean and dry before applying any sealer.

What is composite decking and how is it different from timber?

Composite decking is made from a blend of recycled wood fibres and plastic polymers, creating a durable, low-maintenance alternative to traditional timber decking.

Does composite decking get hot in the Sydney sun?

Some composite decking can get warm in direct sunlight, especially darker-coloured boards.

Sydney Deck recommends lighter-coloured boards for north-facing or full-sun decks.
