How to Paint Garden Furniture

Painting your garden furniture is one of the most cost-effective ways to refresh your outdoor space. Whether you're reviving a tired wooden bench, updating a metal garden furniture set, or giving a worn chair a new lease of life before summer, a fresh coat of paint goes a long way.

This guide covers everything you need to know, step by step.

What Kind of Paint Should You Use for Outdoor Furniture?

The short answer: always use a paint specifically formulated for outdoor use.

Standard interior paint won't hold up against rain, UV exposure, or temperature changes. For garden furniture, you need a paint that's weather-resistant, durable, and designed to flex with the material underneath. Here's what to look for by material:

Wooden garden furniture: Use an exterior eggshell or satin finish paint. These offer strong weather resistance without the heavy sheen of a full gloss. Water-based exterior paints are a practical choice — they dry quickly, clean up easily, and hold their colour well over time.

Metal garden furniture: Look for a paint formulated for metal, or a multi-surface exterior paint that explicitly covers metal. Rust-inhibiting formulas are worth the investment, especially for steel. Powder-coated aluminium can also be painted, but requires careful preparation first.

Rattan garden furniture: Synthetic rattan garden furniture can be painted using a spray paint designed for plastics or a multi-surface exterior paint. Natural rattan requires a wood-specific exterior paint. In both cases, thin, even coats are essential — too much paint at once clogs the weave.

What finish should you choose? Satin and eggshell are the most versatile for outdoor furniture — they're durable, easy to clean, and won't show every mark. Gloss offers maximum durability and a high-shine finish, but imperfections are harder to hide. Matt finishes are less common outdoors because they're harder to maintain.

Do You Need to Prime Garden Furniture Before Painting?

It depends on the material — but when in doubt, prime.

Priming is the step most people skip, and the reason most paint jobs don't last. Here's a quick breakdown:

Wood: If you're painting bare or stripped wood, a primer helps the topcoat bond properly and improves coverage. If the wood has existing paint that's in good condition, you can sand lightly and go straight to topcoat. Knotted wood should always be primed first to prevent resin bleeding through.

Metal: Always prime bare metal, particularly steel or iron. Use a rust-inhibiting primer before applying your chosen topcoat. Even aluminium — which doesn't rust — benefits from a bonding primer to prevent peeling.

Rattan (synthetic): A light sanding and a bonding primer will help paint adhere to smooth plastic-based rattan surfaces. Without it, paint is more likely to chip or peel over time.

The rule: If you're painting a new, bare, or previously unpainted surface, prime it. If you're repainting an already-painted surface that's in good condition, a light sand and clean is usually enough.

How to Paint Garden Furniture: Step by Step

Step 1: Clean the furniture thoroughly

Before anything else, the surface needs to be clean, dry, and free of dirt, grease, and mildew. Use warm soapy water and a stiff brush, or a dedicated sugar soap solution for older, grimier pieces. Leave it to dry completely — painting on a damp surface is one of the most common causes of peeling.

Step 2: Sand the surface

Sand with medium-grade sandpaper (around 120 grit) to remove loose or flaking paint, smooth out rough areas, and give the new paint something to grip. For metal, this step also removes surface rust. Wipe away all dust before moving on.

Step 3: Fill any damage (wood only)

For wooden furniture with cracks, holes, or deep grain damage, use an exterior wood filler. Apply, allow to harden, then sand smooth. Don't skip this step — paint won't hide structural imperfections.

Step 4: Apply primer (where needed)

If you're priming, apply one even coat and allow it to dry fully according to the manufacturer's instructions. Don't rush this stage — a properly dried primer makes all the difference to the final result.

Step 5: Apply your first coat of paint

Use a brush, roller, or spray paint depending on the surface and your chosen method (see below). Apply thin, even coats rather than one thick coat. Thick paint takes longer to dry, is more likely to run, and won't last as long. Work with the grain of wood.

Step 6: Sand lightly between coats

Once the first coat is dry, lightly sand with a fine-grade sandpaper (180–220 grit) to remove any dust particles or brush marks. Wipe clean before applying the second coat.

Step 7: Apply a second coat

Most surfaces benefit from two coats as a minimum. Allow the final coat to cure fully before using the furniture — this usually takes 24–48 hours, though some paints recommend longer.

Is It Better to Spray Paint or Brush Garden Furniture?

Both work well — the right choice depends on the furniture.

Spray painting is faster and gives a smoother, more even finish with no brush marks. It's particularly well-suited to rattan garden furniture, where getting a brush into every crevice of the weave is difficult. Spray paint is also a good option for metal furniture with intricate detailing. The downsides: you'll need to mask off surrounding areas carefully, and multiple thin passes are essential to avoid drips.

Brush painting gives you more control and is better suited to larger flat surfaces like wooden garden furniture. A good quality exterior brush produces a clean finish with minimal effort. Use a 2–4 inch brush for larger areas and a smaller detail brush for legs and edges.

For most outdoor garden furniture, the practical recommendation is:

• Rattan and intricate metal pieces: spray paint
• Flat-surfaced wood and simple metal sets: brush or small roller
• Large projects or multiple pieces: a combination of both

Tips for a Long-Lasting Finish

• Paint in the right conditions. Aim for a dry day above 10°C with no rain forecast for at least 24 hours. Avoid painting in direct sunlight — it causes paint to dry too quickly and can lead to cracking.
• Don't skip sanding between coats. It takes five minutes and makes a significant difference to the final result.
• Protect your furniture once painted. A set of garden furniture covers will extend the life of both the furniture and the paint job, particularly over winter.
• Store cushions separately. Even the best paint job won't protect cushions from prolonged damp — bring them in during bad weather.
