Freshly painted stairs can look stunning. Crisp lines. Fresh colour. Instant upgrade.
But if the paint starts peeling in a month or the treads turn into a slip-and-slide, the only thing going down those stairs will be your mood.
The good news: if you choose the right products and follow the right order, you can get beautiful, durable, non-slip stairs that actually hold up to real life.
Let’s walk through it step by step.
Choose the Right Paint & Finish
Your stairs take a beating. Pets. Kids. Groceries. That one friend who stomps. So you need products made for abuse – not wall paint pretending to be tough.
Best types of paint for stairs
Use a floor-rated or porch & floor paint. These are designed for high traffic and scuffing.
Look for labels like:
- Porch & floor enamel
- Floor and patio paint
- Interior / exterior floor paint
Gloss level:
- Satin or low-sheen: Best for treads. Enough durability without showing every speck of dust.
- Semi-gloss: Good for risers, balusters, and handrails where you want easier cleaning.
Then you layer in the secret weapon: a non-skid additive.
Non-skid additives
These mix directly into your paint or clear coat to create fine texture. Common types:
- Silica sand
- Ground polymer / plastic grit
- Pre-made non-slip packets from the paint aisle
Use them on:
- Treads (always)
- Landings
- First and last step – where people are most likely to slip
Here’s a quick cheat sheet:
| Surface | Paint Type | Sheen for Treads | Non-Skid Additive? |
| Interior wood stairs | Floor or porch & floor enamel | Satin | Yes |
| Concrete stairs | Concrete floor / epoxy paint | Satin / Low gloss | Yes |
| Metal stairs | Metal-safe floor or epoxy paint | Satin | Yes |
Key takeaway: If the label doesn’t say floor, porch, patio, concrete, or epoxy, skip it. Wall paint will peel and polish into a slippery surface on stairs.
Gather Your Materials
Before you touch a brush, get everything in one place. Future you will be grateful.
You’ll need:
- Primer
- Bonding primer for wood
- Masonry primer for concrete
- Metal primer for steel / iron
- Floor paint
- Interior or interior/exterior floor or porch paint
- Polyurethane or clear floor sealer
- Water-based for faster dry time and less yellowing
- Floor-rated, not just general furniture poly
- Non-slip / grit additive
- For paint or topcoat (or both)
- Painter’s tape
- For stringers, risers, walls, and edges
- Brushes & rollers
- Angled sash brush for edges and balusters
- Small foam or microfibre roller for treads and risers
- Prep supplies
- Utility knife and pry bar (for carpet removal)
- Filler or wood putty
- Sandpaper (120–150 grit) or sanding sponge
- Vacuum and tack cloth or microfibre cloth
- Mild cleaner or TSP substitute
Pro tip:Buy all paint and clear coat from the same brand when possible. It reduces compatibility surprises like soft finishes, wrinkling, or peeling.
Prepare the Stairs
Prep is where you decide whether your paint job lasts 6 months or 6 years. Do not rush this part.
Cleaning & repairing
- Remove carpet or runners
- Pull staples with pliers.
- Pry tack strips carefully using a flat bar.
- Remove old finishes that are failing
- If paint is peeling, scrape off anything loose.
- Feather rough edges with sandpaper so they don’t telegraph through.
- Clean like you mean it
- Vacuum the stairs thoroughly.
- Wash with a degreaser or TSP substitute, especially on older stairs with wax, polish, or years of skin oils on the nosing.
- Rinse with clean water and let dry completely.
- Repair damaged areas
- Tighten any loose boards or squeaks with screws.
- Fill nail holes, cracks, and dents with wood filler (for wood) or patching compound (for concrete).
- Let the filler dry, then sand level.
- Lightly sand all paintable surfaces
- Use 120–150 grit sandpaper. You are scuffing, not stripping.
- Vacuum and wipe with a damp cloth or tack cloth to remove dust.
Fun fact:Stairs concentrate foot traffic into a tiny area. Per step, they can get more wear per square centimetre than your kitchen floor. That’s why prep and product choice matter so much.
Masking: Tape Like a Pro
Good lines instantly make your stairs look more expensive and intentional.
Tape off:
- The edges where treads meet the stringers
- Along walls and trim
- Any areas you want to keep natural wood
- Brackets, metal spindles, or hardware you don’t want painted
Press the tape down firmly with your fingernail or a plastic card to stop paint from bleeding underneath.
Prime the Stairs
Primer is the glue between your surface and the paint. Skip it and you risk peeling.
Prime:
- Treads
- Risers
- Handrails
- Balusters
- Landings
Choose the right primer:
- Wood: Bonding or adhesion primer. If there are stains or knots, use a stain-blocking primer.
- Concrete: Masonry or concrete primer designed for horizontal surfaces.
- Metal: Rust-inhibiting metal primer.
Apply one even coat using:
- A brush for edges, corners, and detailed areas
- A roller for wide, flat parts
Let it dry fully according to the label before you paint.
Key takeaway: If your stairs are glossy, dark, stained, or previously waxed, never go straight to paint. A bonding primer is your best defence against chipping and peeling.
Paint Handrails & Balusters First
Handrails and balusters are drip factories. If you leave them to the end, you risk ruining finished treads.
- Start with the handrail
- Use a high-quality angled brush.
- Work in sections, keeping a wet edge so you don’t get lap marks.
- Paint the balusters
- Load the brush lightly to avoid runs.
- Spin the brush gently around each baluster to get all sides.
- Check for drips
- Look from below and from the side.
- Smooth out any drips before they dry.
Let these dry completely before you touch the steps. If needed, apply a second coat and let that dry too.
Paint in Alternating Steps
You still need to use your stairs, right? This is where the alternating-step strategy saves your sanity.
How to do it
- Plan your pattern
- Paint every other tread and riser:
- Paint steps 1, 3, 5, 7, etc.
- Leave steps 2, 4, 6, 8 dry for walking.
- Paint every other tread and riser:
- First coat
- Cut in edges with a brush.
- Roll the centres with a small roller.
- Avoid heavy build-up on the nosing – that’s where paint loves to chip.
- Let it dry
- Follow the label, but plan for about 24 hours between coats on treads for best hardness and adhesion.
- Second coat on the same steps
- Repeat the process for steps 1, 3, 5, etc.
- Let them dry fully again.
- Switch pattern
- Now paint steps 2, 4, 6, 8 the same way: two coats with full dry time between.
Pro tip: Mark the wet steps with painter’s tape or sticky notes at eye level so nobody forgets and plants a footprint in your fresh paint.
If you’re mixing non-slip additive into the paint instead of the topcoat, add it to all tread coats following the instructions on the packet.
Apply the Topcoat with Non-Slip Additive
The topcoat is your armour. It protects the colour and adds durability – and it is a great place to boost traction.
Choosing a topcoat
Use a floor-rated clear coat:
- Water-based polyurethane or acrylic floor finish
- Suitable for stairs / floors (check the label)
Avoid regular furniture poly that is not rated for floors. It may be too brittle or too soft.
Adding non-slip grit
You can put non-slip additive in either:
- The last coat of paint, or
- The first coat of clear, or
- Both, for high-traffic or porch stairs
Common approach that works well:
- Smooth paint coats
- Non-slip in the first clear coat on treads
How to apply the topcoat
- Mix the grit thoroughly into the clear coat as directed. Stir often – the grit settles.
- Brush or roll the clear coat onto the treads, working along the grain for wood.
- Watch for pooling on the front edge of each step. Smooth it out to avoid thick, brittle ridges.
- If you want extra protection, apply a second clear coat (without grit or with a smaller amount, depending on how rough you want it).
Key takeaway: The more grit you add, the safer the tread – but the harder it is to mop. Aim for light to moderate texture, not sandpaper.
Alternative Surfaces: Concrete & Metal Stairs
Not all stairs are timber. Concrete and metal need slightly different prep, but the same two goals apply: bond well and prevent slips.
Concrete stairs
- Prep the surface
- Clean thoroughly – remove grease, dirt, and any sealers.
- Etch or mechanically abrade if required by your paint system.
- Patch cracks and holes with concrete patch and let cure.
- Prime
- Use a masonry or concrete primer that matches your chosen paint.
- Paint choice
- Concrete floor paint or 2-part epoxy floor coating for maximum durability.
- Many epoxy kits include non-slip additive or pre-textured finishes.
- Non-slip
- Mix grit into the final colour coat and/or clear coat.
- Pay extra attention to outdoor steps where rain or snow is a factor.
Metal stairs
- Remove rust and old flaking coatings
- Wire brush, sand, or grind rusted areas to bare metal.
- Wipe with a degreaser to remove oils.
- Prime
- Use a rust-inhibiting metal primer compatible with your topcoat.
- Paint choice
- Metal-safe floor enamel or epoxy coating.
- For exterior metal stairs, pick a product rated for exterior + metal.
- Non-slip options
- Grit additive in the paint or clear coat
- Pre-made anti-slip strips on the front edge of each tread
- Anti-slip tape for quick upgrades
Pro tip: For outdoor concrete or metal stairs, look for labels like anti-slip, traction, or textured and still add extra grit where feet land most. Double insurance is your friend in wet Canadian winters.
Maintenance & Safety
You’ve done the work. Now make it last.
Let the finish cure
There is a big difference between dry to touch and fully cured.
- Light use: After the time on the label (often 24–48 hours).
- Heavy use, moving furniture, or allowing pets: Wait 3–7 days if you can.
- Runners with rubber backing: Only after full cure, or they can imprint or stick.
Key takeaway: The longer you can baby your freshly painted stairs, the harder and more durable the finish becomes. Rushing heavy use is one of the fastest ways to cause peeling.
Cleaning painted stairs
- Use mild cleaners and a damp mop or cloth.
- Avoid harsh chemicals, abrasive powders, or aggressive scrubbing pads.
- Wipe spills quickly so they don’t soften or stain the finish.
Quick safety / upkeep checklist
- ☐ Add non-slip runners or small landing mats if needed
- ☐ Check high-traffic edges once or twice a year for wear
- ☐ Touch up chips early so water and dirt do not get underneath
- ☐ Keep the stairs free of clutter that hides edges or trip points
Pro tip: Keep a small labelled jar of your stair paint and a mini roller or brush handy. A 10-minute touch-up once a year is all it takes to keep stairs looking freshly done.
If you:
- Choose floor-rated paint,
- Use primer that actually bonds,
- Add non-slip texture where feet land, and
- Give everything time to cure,
you’ll have stairs that look sharp, feel safe, and don’t start peeling right when you were getting smug about how good they look.
