How to Respray Garden Furniture Step by Step

Garden furniture takes a beating. Rain, frost, sun, bird droppings and the occasional spilled drink leave tired chairs with flaking paint and rust freckles. Replacing the lot is expensive, but if the frames are sound, a respray can bring them back to life for the price of a few tins and a weekend. This guide shows you how to respray garden furniture step by step, whether your set is metal, timber or plastic.

Check that your furniture is structurally sound first. Heavy rust that has eaten through the metal, rotten timber or brittle, cracked plastic is not worth painting.

What you will need

Preparation
– Brush, bucket, warm water and detergent
– Scrapers, wire brush, sandpaper in several grits or sanding pads
– Degreaser or white spirit alternative suited to your surface
– Rust remover or converter if needed
– Tack cloth or lint-free cloths

Painting
– Primer suited to the material
– Spray paint for outdoor use, in aerosol cans or a sprayer, with a matching clear coat if desired
– Masking tape and newspaper or plastic sheeting
– Dust sheets or a large cardboard area

Safety
– Respirator suitable for paint fumes
– Goggles and gloves
– Old clothes

Check that the paint is labelled for exterior use and for the material you are painting. If you use solvent-based paints, treat ventilation seriously. Our spray painting safety FAQ has detail.

Step 1: Choose a good place and day

Spray outdoors, in a sheltered spot out of wind, or in a well-ventilated outbuilding with doors open. Avoid direct sun on the furniture, damp days and very cold weather. Check the temperature range on the paint label.

Lay a dust sheet or large cardboard to catch overspray. Keep neighbours’ cars, washing and plants out of range.

Step 2: Take it apart

Remove cushions, fabric, slings and any removable hardware. Unscrew arms, legs and fittings where practical. Photograph the assembly so you can put it back. Items such as rubber feet and plastic caps are best removed and replaced afterwards.

Step 3: Clean thoroughly

Scrub the furniture with warm water and detergent to remove dirt, algae, bird droppings and grease. Rinse and let it dry fully. Moisture trapped under paint leads to bubbling.

Wipe with a degreaser or surface cleaner suited to the material. Handle with clean gloves afterwards.

Step 4: Remove loose paint and rust

Metal

1. Scrape off flaking paint.
2. Wire brush rusty areas, then sand back to firm, bright metal where possible.
3. Treat stubborn rust with a rust remover or converter following the instructions closely.
4. Sand the rest of the surface lightly to give the new paint something to grip.
5. Wipe off dust.

Old furniture may carry old paint, which could include hazardous substances. If you suspect lead paint, avoid dry sanding and seek advice.

Timber

1. Scrape and sand off loose paint or varnish.
2. Check for rot by prodding with a screwdriver. Cut out or fill damaged areas using exterior wood filler.
3. Sand with medium, then fine paper along the grain.
4. Wipe off dust.

Plastic

1. Clean thoroughly.
2. Lightly sand to dull the glossy surface.
3. Wipe with a plastic-safe cleaner.

Not all plastics take paint well. Check for special plastic primer or paint labelled for plastic, and test on a hidden area.

Step 5: Mask and protect

Cover anything you do not want painted: rubber, glass tops, threads, labels and adjacent surfaces. For glass-topped tables, remove the glass if you can. Use tape for sharp edges, and crumple foil or paper for tricky areas.

If you can hang parts, do. Hanging chair frames or legs from a line or hooks lets you spray all sides without touching them. Otherwise, lift items onto blocks so you can reach underneath.

Step 6: Prime

Primer improves adhesion and protects against rust and stains.

• Metal: use an anti-rust or metal primer. For galvanised or aluminium, choose one made for those metals.
• Timber: an exterior wood primer, especially on bare patches or knots.
• Plastic: a plastic adhesion primer.

Shake the can for the time stated. Test on a scrap or hidden area. Hold the can about the distance recommended, keep it moving and apply light, even coats. Do not try to get full coverage in one pass. Let the primer dry as instructed. Lightly sand if the label advises, then wipe off dust.

Step 7: Spray the colour

1. Shake the can well and test the spray pattern.
2. Start with the least visible areas, such as undersides and inner faces, then do the top and front.
3. Spray in light, overlapping passes. Keep the can moving, and trigger on just before the surface and off just after.
4. Allow flash-off time between coats. Apply two or three thin coats instead of one heavy one.
5. Rotate or move the piece so you can reach all faces without bending awkwardly or spraying at an angle that causes runs.
6. Keep an eye out for drips. If you catch one just as it forms, tipping the piece can help, but avoid dabbing wet paint.

If you plan to use a sprayer instead of cans, see our article on HVLP versus airless sprayers to pick the right one. For avoiding common faults, read our guide on runs and orange peel.

Step 8: Add a clear coat (optional)

A clear topcoat can add durability and gloss, particularly on timber and decorative metalwork. Ensure it is compatible with the colour coat, follow the drying times and apply thin coats. Some paints already include a protective finish.

Step 9: Let it cure

Dry to the touch is not fully cured. Leave the furniture somewhere dry and sheltered for the time on the label, often several days for a hard finish. Avoid moving it around too much, and keep cushions off until the paint is fully hard, otherwise they can stick or mark the surface.

Step 10: Reassemble and protect

Remove masking carefully, ideally while the paint is touch dry but not fully hard, to get clean edges. Reassemble, replace feet and fittings and put cushions back. Consider fitting new rubber feet to keep legs off damp patios.

Looking after the new finish

• Wash with mild soapy water and a soft cloth, not harsh abrasives.
• Touch up chips quickly before rust takes hold.
• Cover or store furniture over winter if you can.
• Avoid leaving wet cushions on the surfaces.
• Re-inspect each spring, and treat small areas as needed.

Choosing colours and finishes

• Darker colours show dust and water marks less but get hot in sun.
• Light colours feel fresher but can show dirt.
• Matt and satin finishes hide minor imperfections better than gloss.
• Hammered effect paints work well on rough metal.
• Test a small patch to check colour in daylight.

Mistakes to avoid

• Painting over damp or dirty surfaces.
• Skipping primer on bare metal.
• Spraying in direct sun or wind.
• Applying thick coats to finish faster.
• Using interior paint outdoors.
• Reassembling before the paint has hardened.
• Neglecting safety gear.

Frequently asked questions

Can I spray paint over old paint?

Yes if the old paint is sound and well bonded. Clean, sand to key the surface and use a compatible primer. Remove anything flaking.

How many coats do I need?

Usually one or two light primer coats and two or three light colour coats. Follow the label.

Is spray paint durable enough outdoors?

Products labelled for exterior use are designed to resist weather, but longevity depends on preparation and conditions. Maintenance helps.

Can I respray wicker or rattan?

Rattan-effect plastic can be painted with the right primer and paint, but natural cane can behave differently. Test a hidden area first.

Wrapping up

To respray garden furniture, pick a calm day, clean thoroughly, remove rust and flaking paint, mask carefully, prime, then apply thin coats of exterior paint. Let it cure properly before use. With decent preparation, your set will look fresh again and stand up to the seasons.
