How to Paint a Shed (Best UK Paints & Techniques)
Painting your shed isn’t just about looks — it’s essential protection against rain, rot, and UV damage. This guide explains how to paint a shed properly, what paints to use, and how to make the finish last for years.
Why Painting a Shed Is Important
Painting your shed protects the timber from rain, UV exposure, mould, and cracking. It also improves appearance and can extend the lifespan of your shed by many years.
- Seals timber against moisture
- Prevents rot and fungal growth
- Enhances appearance and colour longevity
Most garden sheds and wooden sheds require regular re-treatment every 2–5 years.
What Paint Should You Use on a Shed?
Not all paints are suitable for exterior timber. For best results, use products designed for outdoor use.
- Shed & Fence Treatments: Penetrate timber and resist moisture.
- Exterior Wood Paint: Thicker coating, more colour choice.
- Wood Preserver: Protects against rot and insects.
Always check that the product is suitable for exterior wood and compatible with pressure-treated timber.
How to Paint a Shed (Step-by-Step)
- Prepare the surface: Brush off dirt, algae, and loose paint.
- Repair damage: Fill cracks or sand rough areas.
- Apply the first coat: Use a brush or roller following the wood grain.
- Allow to dry: Follow manufacturer drying times.
- Apply a second coat: For full weather protection.
How Often Should You Repaint a Shed?
Most sheds need repainting every 2–5 years depending on exposure and paint quality. South-facing sheds may require more frequent treatment.
Regular maintenance dramatically extends the life of your shed and keeps it looking fresh.
