Paint, or a coloured fence treatment, gives solid colour and suits rough-sawn fence panels. Stain adds colour while letting the grain show. Oil soaks into the wood, keeps it looking natural and suits decking best, but needs re-applying most often.
The right choice depends on the timber, what is already on it and how much upkeep you want. This guide from PDS Painting Birmingham compares the three, then covers preparation, timing and the mistakes that make finishes peel. You’ll find more in our painting and decorating guides.
Paint, Stain and Oil Compared
| Finish | How it looks | Best for | Durability and upkeep | Can you switch later? |
|---|---|---|---|---|
| Fence paint / treatment | Opaque, solid colour | Rough-sawn fence panels, posts, trellis | Per manufacturer guidance on the tin; recoat when faded | Easy to go over with more paint; moving to stain or oil means sanding back to bare timber |
| Wood stain | Translucent or semi-transparent colour, grain shows | Planed timber, feather-edge and slatted fences | Per manufacturer guidance; darkens with each coat | Can be painted over once sound; lighter stain over darker won’t work |
| Decking oil | Natural, enhances the grain | Softwood and hardwood decking | Per manufacturer guidance; re-oil most often | Easy to top up; can be stained or painted later once weathered and clean |
| Decking stain | Coloured, some grain shows | Decking where you want a set colour | Per manufacturer guidance; can peel if over-applied | Can be painted over; oil won’t soak in over it |
| Decking paint | Opaque, strong colour | Tired or mismatched boards | Per manufacturer guidance; wears on walkways | Needs stripping back to change to oil or stain |
If you are unsure how a product will look on your timber, test it on an offcut or a hidden board first.
Painting a Fence
Most garden fences in the UK are rough-sawn softwood panels, and a water-based fence paint or treatment suits them well. It goes on quickly, covers uneven timber, hides weathering and comes in a wide range of colours. Greys, blacks and greens are popular because they make planting stand out and suit most brick.
Use a wide brush and work the paint into the overlaps and rough grain, following the direction of the boards. A roller with a long pile can speed up flat panels, with a brush to finish the edges and gaps. Do posts, rails and the tops of panels as you go.
On bare or faded timber, plan for two coats. The first soaks in; the second evens out the colour.
Some DIYers use a garden sprayer. If you do, watch for overspray: it drifts onto neighbours’ cars, windows, paving and plants, so sheet everything and avoid breezy days.
Be considerate about the other side. Only paint your neighbour’s side of the fence, or a fence they own, if they have agreed.
Staining a Fence
Stain is the better choice where the timber is worth seeing - smooth, planed boards, or a new feather-edge or slatted fence. It colours the wood without hiding the grain.
Stains darken with each coat, so start light and build up. A preservative treatment protects timber against rot and insects; a decorative stain adds colour and some water repellence. Some products do both, so check the label for what you need.
Staining, Oiling or Painting Decking
Decking has a harder life than a fence. Horizontal boards hold rain and dew, take full sun on top and get walked on, so they weather far faster than vertical panels.
Decking oil penetrates the timber rather than forming a film. It brings out the grain and keeps a natural look. Because it does not sit on the surface, it does not peel - but it wears away, so expect to re-oil more often. The upside is that refreshing it is easy: clean the boards and apply another coat.
Decking stain adds colour as well as protection. It can look very smart, but it is easy to over-apply. Extra coats sit on top of the boards rather than soaking in, and under foot traffic they wear, crack and peel. Apply only what the tin recommends.
Decking paint gives strong, even colour and can hide tired or mismatched boards. It forms a film, so on busy routes - steps, the path to the back door - it will wear through over time. Changing your mind later means stripping it back.
All three are available with anti-slip options, either built into the product or as an additive. On shaded decks that stay damp and on steps, it is worth it. Whichever you choose, check the manufacturer’s guidance for how often it needs recoating rather than relying on a general figure.
Can You Use Fence Paint on Decking?
Generally, no. Fence paints are made for vertical, rough-sawn timber and are not designed to take foot traffic, furniture being dragged or standing water. On decking they wear through quickly and can become slippery. Use a product labelled for decking.
How to Prepare a Fence or Deck Before Treating It
- Clear and protect. Cut plants and climbers back from the fence, and cover paving, gravel boards and borders with sheets.
- Brush off dirt. Use a stiff brush to remove dust, cobwebs and loose debris, especially in overlaps and between deck boards.
- Treat algae and mould. Green growth needs a suitable cleaner, left for the time on the label, then rinsed and allowed to dry. Painting over algae traps it and the finish fails.
- Sand or scrub. Scrub decking with a deck cleaner, and sand or scrape off any flaking stain or paint so the new coat goes onto sound timber.
- Repair. Replace rotten boards, rails or posts and tighten or replace loose screws and nails.
- Let new timber settle. New pressure-treated timber is often damp from treatment; follow the manufacturer’s advice on how long to wait before applying a finish.
A pressure washer can speed up cleaning, but use it carefully. Too close or too strong and it raises the grain, gouges soft timber and drives water deep into the wood, which then needs longer to dry.
Best Weather and Time of Year
Timber must be dry, and you need a dry forecast for the full drying period on the tin. Most exterior wood finishes also have a minimum temperature, often somewhere around 5°C to 10°C, but check the tin for the product you are using. Avoid frosty mornings, damp evenings and hot midday sun, which makes finishes dry too fast and patchy. In Birmingham, late spring to early autumn is the usual window. Our masonry guide explains more about when it is too cold or wet to paint outside.
Common Mistakes With Fence and Decking Finishes
- Treating damp timber - the finish can’t soak in or grip, and it fails early.
- Putting oil over paint - the oil has nowhere to go and stays sticky on the surface.
- Too many coats of stain on decking - it builds up, then peels under foot traffic.
- Using fence paint on decking - it is not made to be walked on.
- Skipping the algae wash - green growth comes back through the new finish.
- Working in direct sun - fast drying leaves lap marks and a patchy colour.
- Forgetting end grain and post tops - these soak up the most water and rot first, so give them extra attention.
When to Get a Professional In
Some jobs are bigger than a weekend with a brush. Long fence runs, large or raised decks, and rough or previously painted timber that needs stripping or sanding back all take a lot of time to do properly. Peeling decking that needs restoring to bare wood is particularly hard work. For those jobs, see our fence and decking painting and staining in Birmingham.
It also makes sense to do the garden timber at the same time as the house. If you are already planning exterior house painting, adding the fence and deck means one round of preparation and one spell of good weather.

Fence and decking questions
Is it better to paint or stain a fence?
Paint, or a coloured fence treatment, is usually better for rough-sawn panels: it gives solid, even colour, hides weathering and is quick to apply. Stain suits smooth, planed timber where you want the grain to show. The comparison table above sets out the looks, upkeep and how hard it is to switch later.
Should I oil or stain my decking?
Oil if you want a natural look and easy top-ups - it soaks in, so you can simply clean and re-oil worn areas. Stain if you want a stronger colour, but apply only the number of coats the tin recommends; too much stain sits on the surface of decking and peels under foot traffic.
How often should you treat a fence or decking?
Follow the product's guidance, then watch the timber. When the colour fades or rain soaks in instead of beading on the surface, it is time to re-treat. Decking needs attention more often than fences, because horizontal boards take standing water, sun and foot traffic, while fences shed rain.
Can you paint over a stained fence?
Usually, yes. Once the fence is clean, dry and the old stain is sound rather than flaking, a fence paint will go over it. Going the other way is harder: stain or oil will not soak into timber that has been painted, so you would need to strip or sand back to bare wood first.
What is the best time of year to paint a fence?
In Birmingham, late spring to early autumn usually gives the best conditions. Pick a spell of dry, mild weather with no rain forecast for the drying time on the tin, and timber that has had a few dry days. Avoid frosty mornings, damp evenings and hot midday sun.
Do I need permission to paint my side of a shared fence?
You can treat your own side of a fence you own. If the fence belongs to your neighbour, or you want to paint their side, get their agreement first - ideally in writing - and take care not to splash their garden. This is general guidance, not legal advice; property deeds usually show who owns which boundary.
Do you need to treat new pressure-treated timber?
Pressure treatment protects the timber against rot and insects, but it does not add colour or much water repellence. A finish helps on both counts. New treated timber is often still damp from the process, so follow the manufacturer's advice on how long to leave it before applying paint, stain or oil.
