A new fence looks great for about six months. Then the weather gets to it — UV fades the colour, rain soaks in and raises the grain, and before long you’ve got a grey, rough, tired-looking boundary. Staining a fence protects the wood and restores its appearance, and it’s one of the most straightforward outdoor DIY jobs you can tackle.
Stain vs Paint vs Oil
| Finish | Appearance | Protection | Maintenance | Best For |
|---|---|---|---|---|
| Wood stain | Shows grain, tinted colour | Good UV + moisture | Recoat every 2–3 years | Most fences (recommended) |
| Paint | Solid colour, hides grain | Excellent barrier | Peels/flakes — requires scraping before recoat | Smooth-planed fences only |
| Oil | Natural, shows grain | Moderate moisture, minimal UV | Recoat annually | Hardwood fences, premium look |
| Nothing | Grey weathered | None | None — but wood deteriorates faster | If you like the grey look |
For most garden fences (rough-sawn softwood panels or closeboard), wood stain is the best choice. It soaks into the wood rather than sitting on top, so it doesn’t peel or flake. When it eventually fades, you simply clean and recoat — no scraping required.
Choosing the Right Stain
Fence stains come in two types:
- Water-based — low odour, fast drying (1–2 hours between coats), easy brush cleanup. Slightly less durable than solvent-based. Good for most applications
- Solvent-based — stronger smell, slower drying (4–6 hours between coats), brushes need white spirit. More durable and better penetration into weathered wood. Better for exposed or heavily weathered fences
Popular brands include Cuprinol Ducksback (water-based, one-coat formula), Ronseal Fence Life Plus, and Barrettine Premier Wood Stain. For colour, mid-tones like ‘Harvest Brown’ and ‘Dark Oak’ are the safest choices — very dark colours show every splash and mark, while very light colours fade noticeably.
What You’ll Need
- Fence stain (calculate coverage: typically 5–8m² per litre, depending on wood absorbency)
- 4-inch paintbrush or fence sprayer
- Old sheets or plastic sheeting to protect plants and paving
- Stiff brush or pressure washer for cleaning
- Masking tape (for protecting posts or different-coloured sections)
- Stirring stick
- Old clothes you don’t mind ruining
Step 1: Clean the Fence
This is the most important step. Stain applied to a dirty fence looks patchy, doesn’t penetrate properly, and won’t last. For an old fence, scrub with a stiff brush and soapy water, or pressure wash on a low setting (under 1,200 PSI with a wide fan nozzle to avoid damaging the wood grain). Remove any moss, algae, and flaking material.
For a new fence, brush off any dust and loose fibres. New pressure-treated fence panels sometimes have a waxy surface that repels stain — check this by flicking water at the surface. If the water beads up instead of soaking in, the fence isn’t ready to stain. Wait 3–6 months for the treatment to weather, or lightly sand the surface to improve absorption.
Let It Dry
The fence must be completely dry before staining. After rain or pressure washing, allow at least 48 hours of dry weather. Stain applied to damp wood won’t penetrate properly and will peel. Check the weather forecast — you need a dry window of at least 24 hours after application for the stain to cure.
Step 2: Protect Surroundings
Cover nearby plants with old sheets (not plastic — plants need to breathe). Lay plastic sheeting or cardboard along the base of the fence to protect paving and grass. Fence stain splatters everywhere and stains concrete permanently.
Step 3: Apply the Stain
Brush Method
A 4-inch brush is the traditional method. It’s slower but gives excellent penetration, especially on rough-sawn wood:
- Stir the stain thoroughly — pigment settles at the bottom
- Load the brush without overloading it (dip about 1/3 of the bristles)
- Work from top to bottom, following the grain of the wood
- Apply generously — the wood should look wet but not dripping
- Pay attention to end-grain (cut edges of boards) — they absorb more and need extra stain
- Work one panel at a time for consistent coverage
Sprayer Method
A fence sprayer (pump-action or electric) is 3–5 times faster than brushing. It works best on flat panel fences but can be messy with closeboard fences where the overlapping boards create shadowed areas. If spraying, use a piece of cardboard behind the fence to protect anything on the other side, and always back-brush (go over the sprayed surface with a brush) to work the stain into the grain.
Step 4: Second Coat (If Needed)
One-coat formulas like Cuprinol Ducksback are designed to give full coverage in a single application. Standard stains often benefit from a second coat, especially on porous or heavily weathered wood. Apply the second coat once the first is dry (check the tin for recoat times) — you want it touch-dry but still within the recoat window.
Maintaining Your Stained Fence
- Recoat every 2–3 years, or when you notice fading
- Clean moss and algae annually with a stiff brush — don’t let growth sit on the stained surface as it traps moisture
- Cut back plants that grow against the fence — they trap moisture and accelerate decay behind the stain
- Replace any broken or rotten boards promptly — rot spreads from damaged sections to healthy ones

Common Mistakes
- Staining a wet fence — the stain sits on the surface and doesn’t penetrate. Wait for dry wood
- Not stirring the stain — pigment settles. Stir regularly during application, not just at the start
- Staining in direct sun or heat — the stain dries too fast on the surface, preventing proper penetration. Work in shade or during cooler parts of the day
- Applying too thinly — a thin coat provides minimal protection and fades quickly. Apply generously
- Staining new treated timber too soon — the preservative treatment prevents stain absorption. Wait for it to weather
