How to Restore Weathered Teak and Eucalyptus Outdoor Furniture

Why outdoor timber turns grey

Sun breaks down the colour in the outer layer of timber, and rain washes the loosened fibres and natural oils from the surface. Over months, warm brown becomes silver-grey. It happens to teak and eucalyptus alike, and to the eucalyptus tops on most of our outdoor tables.

The important bit: on sound hardwood, the change is cosmetic. The grey layer is thin, and the timber underneath is still the colour it was. That's why restoration works — you're removing a weathered skin, not rebuilding the wood. The care notes for our all-timber Nassau Rectangular Outdoor Table say exactly this: if the finish lapses and the timber greys, it can generally be restored with light sanding and a fresh coat of finish.

A quick word on names. "Teak" turns up in a lot of product names as a colour. The Nassau, for instance, is solid eucalyptus in a light teak finish. The method below works on both timbers, so you don't need to know which one you have to get started. If you're still choosing a timber, see our teak vs acacia vs eucalyptus comparison.

Restore it or leave it silver?

Both are legitimate finishes. Decide before you start, because it changes how much work you do now and every year after.

Plenty of people restore once, enjoy the warm colour for a season, then decide they prefer the silver look and stop oiling. That's fine. What looks worst is the in-between: oil applied once and left to wear off unevenly.

Check it's worth restoring

Restoration fixes colour and surface texture. It doesn't fix structure. Before you buy sandpaper, spend five minutes on these checks:

• Soft spots. Press firmly with your thumb anywhere that looks dark or spongy, especially leg ends and where slats meet the frame. If the timber gives, there's rot under the surface.
• Loose joints. Rock the piece gently. Tighten bolts and screws now; joints that won't tighten need repair first.
• Cracks. Fine surface cracks along the grain (called checking) are normal in outdoor hardwood and usually sand out or close up once oiled. Cracks running through a leg or rail are structural.
• Mould. Black or green spotting is common after a humid summer. Deal with it during cleaning; our guide to removing mould and mildew from outdoor furniture covers it in detail.

Pieces with aluminium frames make life easier: only the timber top needs work. The Hydra Outdoor Coffee Table and Bendigo Square Outdoor Coffee Table both pair a slatted eucalyptus top with a black powder-coated aluminium frame, and the Tagula 4 Piece Outdoor Sofa Set has a eucalyptus-topped coffee table on the same kind of frame. The aluminium needs no treatment, just a wipe with a damp cloth.

Step 1: Clean the timber

Always clean before you sand. Sanding a dirty surface grinds grime and mould spores into fresh timber.

• Set up. Work on a drop sheet or tarp, out of direct midday sun, and wear gloves.
• Brush off loose dirt and leaves, including between slats.
• Wash with mild soapy water (a little dishwashing liquid in a bucket of warm water) using a soft brush. Work along the grain, never across it.
• Rinse with a hose on low. Don't pressure wash: high pressure tears up the soft grain between the harder growth rings and leaves a furry, rough surface.
• Let it dry completely. Allow at least a full day, longer in humid weather. Sanding or oiling damp timber gives a patchy result.

If the piece only had light greying, you may be pleasantly surprised at this point. A good clean alone often lifts enough grime to make the silver look even and fresh, and if that's the finish you want, you're done.

Step 2: Sand back the grey

Sanding removes the weathered layer and exposes the warm timber underneath. Go gently: you only need to take off the grey, not reshape the piece.

• Protect the frame. On aluminium-framed pieces, mask the powder-coat with painter's tape where it meets the timber. Sandpaper scratches powder-coat quickly.
• Start with medium grit (around 80–120) on heavily weathered surfaces until the grey is gone and the colour is even. Lightly weathered timber can start at 120.
• Finish with fine grit (around 180–220) for a smooth surface that takes oil evenly.
• Always sand with the grain. Cross-grain scratches show up badly once oil goes on.
• Use the right tool. An orbital sander is quick on flat tabletops; sand slats, edges and legs by hand with a sanding block. Avoid belt sanders, which remove too much too fast.
• Remove every bit of dust with a dry brush and a barely damp cloth, then let it dry again.

Slatted tops take longer than they look, because each slat has two edges. Take your time on the edges: they weather fastest and show most.

Step 3: Oil it, or let it silver again

To keep the warm colour

Use an outdoor hardwood oil (or a teak oil made for outdoor use). This is what the care instructions on our eucalyptus tables recommend.

• Pick a dry day with no rain forecast for a day or two. In humid storm-season weather, oil dries slowly and can stay tacky, so a dry spell makes a real difference.
• Apply thin coats with a lint-free cloth or brush, along the grain. Thin is better than thick.
• Wipe off the excess after the time on the tin. Oil left sitting on the surface goes sticky and collects dust and mould.
• Add a second coat once the first has dried, focusing on the tabletop and edges.
• Repeat every 6–12 months. More exposed pieces need it sooner; a breathable cover during long wet spells stretches the gap.

To let it silver

Stop after sanding, or even after cleaning. Fresh timber will weather to an even silver-grey again, usually more uniform than the patchy grey you started with. From then on it needs nothing but a regular clean.

A note on care products

Indoor furniture polishes are the wrong tool for outdoor hardwood. The Guardsman Wood Care Kit, for example, is a cleaning and polishing set made for finished, sealed timber such as veneer, painted and stained surfaces, and isn't for raw, oiled or waxed wood. It's ideal for indoor dining and coffee tables, not for the oiled outdoor tables in this guide. You'll find it, and our fabric and leather care, in our furniture care range.

Rather not do this again?

If oiling isn't for you, consider a composite top next time. The Chalfonte Rectangular Outdoor Table has a slatted Duraboard top on a dark brown powder-coated aluminium frame. Duraboard looks like timber but doesn't need oiling, sealing or sanding. Compare it with timber options in our outdoor dining tables and outdoor coffee tables.

When the result isn't right

• Blotchy colour after sanding. Usually leftover grey or old finish in patches. Sand those areas again with the finer grit until the colour matches.
• Dark spots that won't sand out. Often mould that has gone deeper than the surface. Treat it as described in the mould guide, let it dry, then sand again.
• Rough, furry surface after the first rain. The grain has lifted. Once dry, give it a light pass with fine sandpaper and another thin coat of oil.
• Sticky or patchy oil. Too much oil, or oil applied to damp timber. Wipe back the excess with a clean cloth, let it cure, and use thinner coats next time.
• Sanding uncovered soft timber. Stop. That's structural damage, not weathering, and the piece needs repair or replacement.

Storm season is also the time to protect freshly oiled pieces: move them under cover or use a breathable cover. Our guide to protecting outdoor furniture from storms has the full plan, and the seasonal maintenance checklist shows where re-oiling fits in the year.

Restoring outdoor timber FAQs

• Can you restore grey teak outdoor furniture?

  Yes, as long as the timber is still sound. Clean it with mild soapy water and a soft brush, let it dry completely, sand with the grain to remove the grey layer, then apply an outdoor hardwood oil in thin coats. The same method works on eucalyptus.

• Does grey timber mean the furniture is rotting?

  No. On teak and eucalyptus, silver-grey is a cosmetic surface change from sun and rain and doesn't weaken the timber. Rot shows up as soft or spongy spots that give when you press them with your thumb.

• Do I need to sand weathered teak, or can I just clean it?

  If you're happy with an even silver finish, cleaning is enough. To bring back the warm timber colour on heavily greyed wood, you need to sand: start with a medium grit to remove the grey, finish with a fine grit, and always work with the grain.

• What should I put on outdoor teak or eucalyptus after sanding?

  An outdoor hardwood oil, applied in thin coats on a dry day, with the excess wiped off. Don't use indoor furniture polish: products like the Guardsman Wood Care Kit are made for finished, sealed indoor timber and aren't for oiled wood.

• How often should outdoor timber furniture be oiled?

  Every 6–12 months if you want to keep the warm colour, sooner for pieces in full sun and rain. A breathable cover during long wet spells slows weathering. If you prefer the silver look, you don't need to oil at all, just clean it regularly.

• Can I pressure wash teak outdoor furniture?

  It's best not to. High pressure tears up the softer grain and leaves a rough, furry surface that greys faster. Use mild soapy water, a soft brush and a hose on low instead.
