How to paint or stain a new fence.

What this guide covers:
How long to wait before coating
The water test that tells you it's ready
Oil vs stain vs paint
Exactly how many litres you need
Wait 4 to 6 weeks before coating a new treated pine fence, then apply two coats of oil or stain between 10°C and 35°C. You can coat it sooner using a new-timber preparation product. Allow roughly 0.7 litres per metre of fence for two coats on both sides, and test the timber with water before you start — if the drops bead up, it isn't ready.

That's the answer. Below is why, and the parts most people get wrong.

How long should you wait before staining a new fence?

Four to six weeks for treated pine, in most conditions.

Treated pine leaves the treatment plant wet. The preservative is driven into the boards under pressure using water as the carrier, and a lot of that water is still in the timber when it arrives at your place. Coat it while it's saturated and the finish can't penetrate — the pores are already full — and whatever moisture is left is sealed in behind a film.

You get blotchy colour, poor adhesion, and a coating that lifts within a season. At that point you're not recoating a fence, you're stripping one, across sixty-odd palings, by hand.

There's a second reason. Timber that comes off the saw smooth has a compressed, resin-sealed surface — mill glaze — that repels finish. A few weeks of sun and rain opens it up.

How do you know when the fence is ready to stain?

Don't count days. Test it.

1
Sprinkle water
Flick a few drops of water onto the boards.
2
Watch what happens
Give it about thirty seconds.
ABSORBS = READY
The drops soak in and darken the timber. You're ready to coat.
BEADS = WAIT
The water sits on the surface. Still too wet or too glazed — leave it longer.

Test three or four spots, not one, and test both faces. The shaded southern side of a fence can be weeks behind the sunny side, and it's the one people forget to check.

The water test: beading means wait. Soaking in means it's ready.

Can you stain a new fence straight away?

Yes, if you use a new-timber preparation product.

Most coating brands sell one. It's a scrub-on product that strips mill glaze and surface moisture so you can coat immediately instead of waiting out the weathering period — Cabot's, for example, specifies exactly this as the alternative to the standard four to six weeks.

It's a real shortcut, not a cheat. It also means buying an extra product and wet-scrubbing the whole fence, so it's worth doing if you've got people coming over and it isn't worth doing if you can just wait a month.

One rule if you go this way: stay inside a single brand's system from prep through to topcoat. Mixing one brand's preparation with another brand's stain is the most common reason a coating warranty gets declined.

Does the timber type change the answer?

Yes, and this is where most generic advice falls over.

Treated pine
WAIT 4–6 WEEKS

The four-to-six-week case above, and it's what most Melbourne paling fences are built from.

Hardwood
WEATHER, WASH, WATCH THE RUN-OFF

Merbau, jarrah, spotted gum — doesn't carry the treatment moisture, but it does bleed tannin. Give it a few weeks of weather and a wash before coating, and know that the run-off will stain pale concrete, render and pavers on its way down. Hose it off the same day.

Cypress
COATING OPTIONAL

Naturally durable and doesn't need a coating to last. If you coat it, you're doing it for the look, and leaving it bare to silver off is a perfectly good decision.

Not sure what you've got? Ask whoever installed it. It's a ten-second answer and it changes what you buy.

Should you use oil, stain or paint on a fence?

This is the decision that actually matters, and it's less about colour than about what happens in year five.

RECOMMENDED FOR PALING FENCES
Oil & stain

Penetrating oils and stains soak into the timber instead of sitting on top of it. They fade rather than fail. When they wear out you wash the fence and put more on — no sanding, no stripping. The trade-off is doing it more often.

Trade-offMore often
FRONT FENCES & PICKETS
Paint & film coatings

Paint and other film-forming coatings last longer up front and give you any colour you like. But they sit on the surface, and when a film coating fails it doesn't fade quietly — it peels. Recoating then means stripping back to bare timber across every single paling.

When it wearsPeels
To recoatStrip to bare timber
UpsideLasts longer, any colour
On a standard paling fence, use an oil or a stain. The maintenance is a Saturday with a broom and a brush instead of a week with a sander. Save paint for front fences and pickets, where the finish justifies the future work.
Oil and stain soak in — they fade, not peel.
When a film coating fails, it peels — and then it's a strip-back.

Do you need to stain both sides of a fence?

Coat your side at minimum. A fence sealed on one face and bare on the other dries unevenly and is more likely to cup.

If it's a boundary fence, talk to your neighbour before coating their side. Agree who is supplying the product and doing the work before you start. It adds about an hour to a job you're already standing in front of.

How much stain do you need for a fence?

Coverage runs around 12 square metres per litre on dressed timber and less on rough sawn — a first coat on thirsty new pine can drink close to double.

Halve those figures if you're only doing one side. Buy toward the top of the range — running out halfway along leaves a visible join and costs you a second trip.

When is the best time to stain a fence in Melbourne?

Coatings have a working range, usually 10°C to 35°C. That rules out most Melbourne winter mornings and the worst of a January afternoon, which leaves October through April and the cooler ends of those days.

✓10°C to 35°C
The usual working range for coatings.
✓Dry timber
Passes the water test on both faces.
✕Rain within 24–48 hours
Check the forecast before you start.
✕Direct hot sun
Flashes the carrier off before the finish can penetrate and leaves a patchy surface.
✕Late starts
Starting so late in the day that dew settles on a wet coat.

The practical version: begin on the shaded side in the morning and follow the sun around the house.

How to stain a fence, step by step

01
TEST THE TIMBER.
Water test, three or four spots, both faces.
02
CLEAN IT.
Sweep off dust, cobwebs and leaf litter. Wash any mould or grime and let it dry fully.
03
SAND ONLY WHERE YOU NEED TO
Raised fibres, rough patches. Fresh smooth boards usually need nothing.
04
MASK WHAT YOU DON'T WANT COATED.
Brickwork, letterboxes, plants at the base.
05
FIRST COAT.
If you're spraying, always back-brush behind the spray to work the finish into the grain — spray alone sits on the surface. Do one full paling top to bottom before moving to the next, or you'll get lap marks you'll see for years.
06
SECOND COAT
Once the first is dry. Most products want a minimum of two hours.
07
LEAVE IT ALONE.
Many coatings take up to seven days to cure fully. Keep the sprinkler off it.

How often should you recoat a fence?

Don't work to a calendar. Work to the water test.

ONCE A YEAR
Flick water at the fence.
STILL BEADING
The coating is still working.
SOAKS STRAIGHT IN
The coating is spent. Time to recoat.

On a Melbourne fence that's typically two to four years for an oil, longer for a good film coating on a sheltered aspect. North and west-facing sections always go first.

Five mistakes that cost people a fence

1Coating timber that's still wet.
2Coating over dust, cobwebs or mould.
3Coating in direct hot sun.
4Buying too little and joining mid-run.
5Mixing brands within a single coating system.

Frequently asked questions

Can you stain a fence the same day it's installed?
Not with a standard oil or stain — the timber is too wet. Use a new-timber preparation product first, or wait four to six weeks.
Is it better to stain or paint a fence?
For a paling fence, stain. It fades instead of peeling, so recoating is a wash and a brush rather than a strip-back. Paint suits front fences and pickets where the finish matters more than the maintenance.
Can you stain a wet fence?
No. The finish can't penetrate wet timber, and any moisture left in the boards gets sealed in behind the coating.
Do you have to sand a new fence before staining?
Usually not. New boards generally need a clean rather than a sand. Sand only raised fibres or rough patches.
How long does fence stain take to dry?
Touch dry in about an hour and recoatable in about two, but full cure can take up to seven days.

Built by Boundary Co.

We build fences across Greater Melbourne. We don't coat them — coating has its own weather window and its own product warranties, and it's better done by you a month after we've left, or by a painter who does it every day.

What we do is tell you exactly what timber went into your fence and what it needs, so whoever picks up the brush isn't guessing.
