Painting stairs: how to give your wooden staircase a durable finish

Painting a staircase is less about skill than about sequence. Worn treads, dark wood from the nineties, or a finish that's flaking at the edges – all of that can be changed over one long weekend. There are two things you need to get right: the build-up of the finish, and how you actually get upstairs while it's drying.

Why treads are treated differently from furniture

A staircase is the hardest-worked painted surface in the whole house. That changes every decision, from the primer to the final sanding.

Point load, not surface contact

A cupboard gets touched, a step gets trodden on – with your full body weight, on a few square centimetres, hundreds of times a day. Add grit under your soles, which acts like sandpaper. A finish that's meant to withstand that has to be resistant to mechanical stress.

The tread and everything else

Treads, risers, stringers and handrails are four different jobs. Only the tread gets stepped on; risers and stringers get, at most, the tip of a shoe. So you can happily use different shades for each, and give the tread build-up your closest attention.

The surface gives itself away at the edge

Before you buy anything, take a look at the edges and the area under the handrail. That's where the old finish is least worn, and you can see whether it's varnished, oiled or waxed. Nothing sticks to waxed surfaces until every last trace of wax is gone.

The trick that keeps the staircase usable

The most common question first, because it decides your whole schedule: how do you get upstairs while everything below is still fresh?

Every other step, in two passes

You paint every other step first and let it cure fully. During that time, you use the steps in between – standing a bit wider than usual, but without any real climbing. Once the first set can take weight, the skipped steps follow.

Mark them, so no one steps wrong

Tape a strip of masking tape to the handrail above every freshly painted step. It sounds excessive, until the first family member comes home in the dark. A note at both ends of the staircase belongs to the same idea.

Plan your schedule around it

With two passes and two coats each, you're working across four sessions, not one. So plan the staircase over a long weekend, and time the final coat so the surface can be left undisturbed for as long as possible afterwards.

Which finish belongs on treads

Wall paint and unsealed chalk paint have no business on treads. What you need is a finish made for furniture, wood and heavily used interior surfaces.

re-box protect for the tread

re-box protect is re-box's satin-finish furniture and colour lacquer. It's resistant to mechanical stress, everyday dirt and outside influences – the three demands that define a step. It's mixed in any shade from the lacquer range, in 750 ml tins.

No primer, no hold

Before the lacquer comes re-box core. The primer bonds well to a wide range of surfaces, and that matters especially on a staircase, because you're almost always dealing with mixed surfaces: sanded-back old paint next to bare wood next to freshly filled patches. The primer evens all of that out.

Satin, not matt or high gloss

Satin is the practical middle ground for treads. You can wipe it clean without every little imperfection standing out as if under a mirror, and it shows scratches less than a high-gloss surface would. On a staircase that matters twice as much, since hallways often get raking light.

What should be within reach on the top step

A staircase is a narrow workspace. Everything you need up there should already be up there – every extra trip across fresh steps is a risk.

• Primer for the first build-up
• Furniture lacquer in your chosen shade
• A small paint roller for the treads
• A 35 mm synthetic-bristle lacquer brush for edges, stringers and profiles
• Sandpaper in two grits: coarser to strip back, fine to key the surface
• Wood filler for knots, dowel holes and dents
• Degreaser for leftover polish and care products
• Masking tape to mark the freshly painted steps

Why the small roller is the right one

A tread is rarely wider than 30 centimetres. A large wall roller won't reach the edge or sit cleanly into the corner by the stringer. The small paint roller covers the surface in two to three passes, with the brush cutting in the edges beforehand.

Everything together in one package

If you'd rather not put the tools together yourself, Treppe streichen is the ready-matched project package with lacquer in your chosen shade and the right accessories. If mixed paint is included, the whole box is excluded from returns – so only order the shade once you've seen it.

Steps 1 to 3: clean, sand, fill

Not a single drop of paint reaches the staircase yet at this stage. And still, this is the part that decides whether the finish still looks flawless in two years.

1. Clean and check

Vacuum thoroughly, then wipe down with a damp cloth. Scrape off any loose old paint, check for wobbly steps and protruding nail heads and secure them. Remove any traces of polish or care products with a degreaser – on old staircases, they're the most common invisible enemy of adhesion.

2. Sanding

Sand any firmly bonded old lacquer until the sheen is gone. Wherever the finish is flaking, work down to solid, load-bearing wood. Do edges, profiles and the transitions to the stringer by hand. Then remove the dust – more thoroughly than feels necessary: vacuum first, then go over everything again with a slightly damp cloth.

3. Repairing

Fill knotholes, old dowel holes and dents with wood filler, let it dry and sand it level. It's better to apply too much filler than too little – you can always sand off the excess, but topping up means a second drying cycle.

Steps 4 to 6: priming, painting, repeating

Now it starts to show. From here on, the same rule applies to every lacquered surface: thin and twice beats thick and once.

4. Priming

Bare or fully sanded wood needs an adhesion primer, and mixed surfaces even more so. Apply it thinly, edges first, and follow the drying times stated on the tin. The primer coat also makes it easy to spot any unevenness you might have missed before.

5. First coat of lacquer on every other step

Cut in edges and profiles with a brush first, then roll the tread surface with the small roller in the direction of foot traffic. Work from top to bottom so you don't box yourself in, and mark each finished step on the banister right away.

6. Intermediate sanding and second coat

Once the first coat is fully dry, lightly matt it down, remove the dust and apply the second coat. Then it's the turn of the second set of steps – same process, same rhythm. Only once both sets have had two coats is the staircase finished.

Colour, quantity and timing

Three decisions best made before the first piece of sandpaper comes out, not halfway through the staircase.

Which shade works in a staircase

Staircases often get little daylight, which is why a shade with depth feels more pleasant than a pure white that turns grey. Forge Grey No. 28 Lack is a calm, strong grey that forgives dust and scuffing. If you prefer something warmer, go for a deep green like Hearthstone Moss No. 8 Lack. The whole family lives under Lackfarben Grau.

Test the shade on-site beforehand

Hold the shade up to the step, not to the screen. With the Farbmusterkarten you can see how the colour behaves in the staircase – differently under the ceiling light upstairs than downstairs in the hallway. Since every colour is mixed only after ordering, an individually mixed shade is excluded from the right of withdrawal – so the sample card is the cheaper detour.

Quantity and delivery time

Calculate treads, risers and stringers separately and plan for two coats plus primer. A straight staircase with fourteen steps quickly adds up to more surface area than you'd guess. Order in good time: delivery takes 3–5 working days from receipt of payment, because every shade is mixed individually.

Mistakes that really hurt on a staircase

You can't cover up a botched step the way you can a wall. These three points are almost always to blame.

Painting everything at once

Paint every single step in one go, and you've locked yourself out of half the house. The result: footprints in soft paint or a night on the sofa. The two-pass rhythm costs nothing but a bit of planning.

Painted over wax or polish

Old staircases have often been cared for over decades, and those residues sit deep in the worn areas. Skip the degreasing, and the lacquer will lift first exactly where the traffic is heaviest.

Loaded too soon

Dry means walkable, not load-bearing. Don't lay down runners in the first few days, avoid carrying furniture over the stairs, and follow the times stated on the tin. To see how the same build-up behaves on other surfaces, take a look at Küche streichen statt neu kaufen.

Frequently asked questions about painting a staircase

Can I repaint a lacquered staircase without sanding it down?
No, you can't skip sanding entirely, but a light sanding is enough as long as the old finish is still firmly bonded. The goal is simply to break the sheen. You only need to go all the way down to bare wood where the old lacquer is flaking.

Which paint is suitable for staircase steps?
A furniture and general-purpose lacquer designed for heavily used interior surfaces, built up over an adhesion primer. Matt wall paints and unsealed chalk paints aren't made for tread surfaces and wear through quickly in the most-walked spots.

How do I get upstairs while it's drying?
Via the steps you deliberately skipped in the first round. Paint every other step, let them dry fully, then take the second set – that way the staircase stays usable the whole time.

Paint the stairs or use foil?
Painting is the sturdier solution on worn, profiled steps. Foil traces every unevenness and looks worse than the old finish the moment it's damaged, whereas a painted coat can always be touched up.

Do I also need to paint the risers and the stringer?
You don't have to, but it's worth it visually. A common look is a dark tread with light risers – in that case the risers get the same build-up, just without the care a walked-on surface needs.
