Keeping your deck in good condition not only improves how it looks but also helps it stand up to Australia’s tough weather. By taking the time to plan, prepare, and paint carefully, you’ll give your deck a durable finish that protects the timber and keeps it looking its best.
- Planning
Before you even consider opening a paint tin, it’s important to plan ahead.
- Inspect regularly: Stained timber decks should be inspected annually. It is time to restain when the coating looks worn, dry or is porous when droplets of water soak into the surface.
- Check the forecast: Pick a time when humidity is low and no rain is expected for at least 48 hours. Rain and dew can ruin the finish if it hasn’t had a chance to dry beforehand.
- Avoid the heat: Don’t paint in direct sun or on hot timber, as the coating will dry too quickly and result in colour variation or patchiness. Early morning or late afternoon are usually the best times.
Tip: When the deck coating has dried, use furniture pads under chairs and tables to avoid scratches. This small step will help keep your finish looking new for longer.
- Preparation
Preparation is what makes the coating last. A clean, smooth and keyed surface helps the coating soak in properly and prevents peeling.
- Pressure wash the surface: Apply a timber or wood cleaner, then wash it off with a pressure washer. This removes dirt, mould, and old residue.
- Let it dry: After washing, allow the deck to dry completely for at least 24 hours before re-coating.
- Repair and smooth: Use a scrubbing brush to remove loose fibres and any stubborn dirt. Fill small cracks if needed.
- Stay safe: Wear gloves and safety glasses while cleaning and preparing.
- Recoating
Now comes the rewarding part—bringing your deck back to life.
- Stir thoroughly: Mix the paint or stain well with a broad flat paint stirrer to ensure the pigment colour and finish are consistent.
- Start with edges: Use a smaller brush to cut in around edges, corners, and hard-to-reach spots.
- Apply with a deck brush: For larger areas, use a deck brush to spread the coating evenly along the grain of the timber.
- Work in sections: Paint a few boards at a time, moving steadily so you don’t miss any areas.
- Thin coats are best: Apply light, even coats rather than one thick coat—this helps the coating dry properly and last longer.
- Follow drying times: Allow the deck to dry completely before moving furniture back or walking heavily on it.
