Painting Wooden Garden Furniture - All the info, tips and expert advice you need

Published: 18th Jun 2025

Painting your wooden garden furniture is an excellent way to breathe new life into your outdoor space. Whether you're looking to add a fresh pop of colour or revitalise some old favourite pieces with a new coat of paint, this guide provides you with all the tips, techniques, and advice you need to achieve a professional-looking finish that lasts for years to come.

Whether your furniture is brand new or has seen a few summers, a bold new palette of contemporary shades can quickly transform the look and feel of your garden or patio. A fresh coat of paint can make a simple bench or a wooden arbour feel like a brand-new addition. It’s a simple but powerful update that really helps your furniture stand out and feel more “you”.

Sometimes, painting is less about style and more about upkeep. Maybe you're covering up weathered patches, reviving timber that’s gone a bit grey and tired, or hiding those inevitable food and drink spills from the BBQ season. Or perhaps you’re freshening up a veg planter, greenhouse, or cold frame that’s been splashed one too many times during watering.

Whatever your reason, painting softwood garden furniture can be a great way to both transform and protect it. And like with any good DIY project, knowing the steps and having the right tools makes all the difference.

Consider the Age of Your Furniture Before Painting

One of the most important things to consider before picking up your paintbrush is the age and condition of your wooden garden furniture.

If your furniture is brand new – particularly if it's made from pressure-treated softwood, like many garden products – you’ll need to give it time to dry out fully before painting. Pressure treatment helps protect the timber from rot and insects, but it leaves the wood slightly damp for a while.

The general rule of thumb is to wait at least six months after purchase before painting pressure-treated wood. That said, the actual drying time can vary depending on your local climate, the time of year, and the thickness of the timber.

Try this simple test: sprinkle a bit of water on the surface. If the water beads up, it’s still too damp to paint. If it soaks in fairly quickly, you’re good to go.

This step is important – paint applied too early can peel or flake as moisture tries to escape from the wood underneath.

Choosing the Right Paint for Softwood Garden Furniture

When it comes to painting wooden garden furniture, not all paints are created equal. Choosing the right product is key to getting that long-lasting finish you’re after.

Here’s what to look for:

• Exterior-grade paint: Always use a paint designed specifically for outdoor use. Indoor paints won’t hold up against rain, sun, and frost.

• Weather resistance: Look for paints that are water-repellent and UV-resistant to prevent peeling, fading, or cracking.

• Breathability: This is especially important with softwood – it helps moisture escape naturally, reducing the risk of rot.

• Wood compatibility: Some paints are better suited to softwood (like pine or fir), while others are aimed at hardwoods. Read the label carefully.

We recommend looking at products like Protek Wood Stain & Protector, which is widely trusted for timber garden products. It’s available in loads of colours, and it’s designed to withstand the elements without flaking or fading.

Preparing the wooden furniture for painting

Before you can begin painting your wooden garden furniture, it's crucial to prepare the surface properly. This step is often overlooked, but it's essential for ensuring a smooth, long-lasting finish.

Start by thoroughly cleaning the furniture to remove any dirt, grease, or debris that may have accumulated over time. Use a mild soap and water solution or a specialised wood cleaner to scrub the surface, paying close attention to any crevices or hard-to-reach areas. Once the furniture is clean, allow it to dry completely.

Next, inspect the furniture for any damage or imperfections, such as cracks, splinters, or uneven surfaces. Address these issues by sanding down the affected areas and using wood filler to smooth out any irregularities and create a uniform surface to which paint can adhere.

Wipe away any dust or debris with a clean cloth, and then apply a wood primer. Priming the surface will help the paint adhere better and provide an additional layer of protection for the wood. Choose a primer that is specifically formulated for outdoor use and compatible with the type of paint you'll be using.

How to Prepare Wooden Garden Furniture for Painting

Before you even think about applying paint, make sure the wood is clean, dry, and smooth. This part takes a bit of time but makes a huge difference to the final finish.

Step 1: Clean the furniture thoroughly

Remove all dirt, algae, mildew, and grease. Use:

• A mild soap and warm water solution for general cleaning.

• Or a dedicated wood cleaner if your furniture is especially weathered or stained.

Use a soft-bristle brush or sponge to get into corners and slats. Once clean, rinse well and let it dry fully – ideally for 24–48 hours.

Step 2: Sand and inspect the surface

Check for:

• Rough patches

• Splinters

• Old flaky paint

• Any cracks or damaged areas

Sand everything down using medium-grit sandpaper (around 120–150 grit). For stubborn old paint, you may need a coarser grit to start.

This helps the new paint grip better and gives you a smooth surface for the best finish.

Step 3: Fill gaps and smooth out damage

If you find cracks or dents, use an exterior-grade wood filler. Apply it with a putty knife, let it dry, and then sand it smooth.

Step 4: Apply a primer

Priming helps paint stick better, improves coverage, and offers extra protection – especially on softwood, which can be more porous than hardwood.

Use a primer suited for exterior wood and make sure it's compatible with the paint you've chosen.

Step-by-Step Guide to Painting Wooden Garden Furniture

1. Check the weather

Painting outdoors? Choose a dry, mild day – ideally above 10°C, with low humidity and no rain forecast. Direct sunlight can dry the paint too quickly and cause bubbling, so aim for an overcast but dry day if possible.

2. Stir the paint well

Sounds simple, but it's often skipped. Stir your paint thoroughly for a smooth consistency and even colour.

3. Apply the first coat

• Use a good-quality brush or roller. For detailed areas or slats, a brush is ideal. For flat surfaces, a small foam roller can give a super-smooth finish.

• Apply a thin, even coat. Don’t overload the brush – it’s better to build up layers than risk drips or sagging paint.

4. Let it dry properly

Follow the manufacturer’s guidance for drying time – this is usually 2–4 hours between coats, but can vary.

Make sure furniture is kept out of the rain during this time. If you’re working on larger pieces like arbours or benches, tackle them in sections to avoid smudging.

5. Apply a second coat

Once the first coat is fully dry, apply a second. This will give you a richer colour and stronger protection. Some paler colours or weathered timber may benefit from a third coat.

6. Optional: Finish with a sealant

For extra durability, especially in wet or coastal areas, consider applying a clear wood sealant or outdoor varnish after your paint has cured.

Caring for Painted Wooden Garden Furniture: Aftercare Tips

A painted finish won’t look after itself forever. With a bit of ongoing care, you can keep your furniture looking great for years.

• Regular cleaning: Wipe down surfaces every few months with a damp cloth and mild soap.

• Touch up chips and scratches quickly to stop moisture getting into the wood underneath.

• Avoid abrasive cleaners that could damage the finish.

• Store or cover furniture during the winter months if possible. Use breathable, waterproof covers – avoid plastic sheets which can trap moisture.

Frequently Asked Questions

What type of paint is best for outdoor wooden furniture?

Use a high-quality acrylic latex or oil-based exterior paint that is weather-resistant and suitable for wood. Look for paints specifically designed for timber garden furniture.

Can I paint pressure-treated wood?

Yes – but only once it’s completely dry. Wait at least six months after buying pressure-treated softwood and check using the water-drop test before painting.

Do I need to prime my garden furniture before painting?

Yes, especially for softwood or bare wood. A primer helps the paint stick, reduces the number of coats you’ll need, and adds an extra layer of protection.

How many coats should I apply?

Two coats are usually enough for good coverage and protection. Some colours or older furniture may need a third.

How often should I repaint wooden garden furniture?

Typically every 2–5 years, depending on exposure to sun, rain, and frost. Always check the manufacturer’s guidance for your specific paint.

How do I maintain the painted finish?

• Wipe off dirt regularly
