You spot a chip on the skirting board, or a small flake hanging off the kitchen wall, and figure it’s a five-minute fix. Then you slap on some leftover paint and a fortnight later the patch looks worse than the chip did.
Chipped paint is one of those jobs that looks trivial but trips up most DIYers, because the repair isn’t really about the paint. It’s about what caused the chip in the first place. Get that wrong and you’ll be back with a paintbrush every few months.
This guide walks you through how to repair chipped paint properly, the way a professional painter would: diagnose first, fix the underlying issue, then make it invisible. By the end, you’ll know exactly what to do and when to leave it alone.
Skip this step and you’ll end up repairing the same spot again and again. Chipped paint is a symptom; the cause is what actually needs addressing. Most chips fall into one of four categories.
If a wide patch of paint lifts off cleanly when you pick at it, the original coat wasn’t bonded properly. Common causes: skipping primer on bare plaster or new wood, painting over dust, or applying latex over old oil-based paint without a bonding primer. The fix is to take the affected area back to a sound surface and start over.
Bubbles around the chip, brown staining, or paint that’s still soft to the touch all point to moisture. In an Irish home, that’s usually condensation (bathrooms, exterior walls, behind heavy furniture against a north-facing wall) or rising damp at lower levels. Don’t paint over it. Find the source and dry the area properly first. Otherwise the chip will be back within months.
Door handles, vacuum cleaners, kids’ toys, dog tails. The boring physical knocks. These are the easiest to repair because the surface underneath is usually fine.
Exterior woodwork around windows, sills, gates and fences takes a beating from sun, rain and salt air. After five or six years, even a good exterior paint job will start chipping at the edges. This is normal wear, not a defect.
Scrape gently outward from the chip until the surrounding paint stops lifting. If a flake doesn’t want to come off, leave it. Feather the edges with sandpaper so the transition from old paint to bare surface is gradual, not a sharp shelf.
If the chip is deeper than a coat of paint, exposing plaster, wood or render, fill it. Apply filler slightly proud of the surface, let it dry, then sand flush with 220-grit. On exterior woodwork, use a flexible filler that can move with the timber. Standard interior Polyfilla will crack outdoors.
Any repaired area must be primed. This is the step most homeowners skip and most regret. Primer seals the patch, locks down dust, and gives the topcoat something consistent to bond to. Without it, the repaired patch will show through every angle of light, no matter how well you match the paint.
Use a small brush to feather the new paint slightly into the surrounding old paint, rather than stopping cleanly at the chip’s edge. This is the single biggest difference between an obvious touch-up and an invisible one.
Thick paint leaves a raised patch that catches the light. Two thin coats with light sanding between them will blend in far better, even if the colour match isn’t perfect.
Here’s the bit most online guides skip entirely. Even if you have the original tin in the shed, the paint on your wall has changed. UV light, smoke, cooking grease, and the natural yellowing of white paint over time all mean your repair patch will sit slightly darker, cleaner, or yellower than the surrounding wall.
There are three honest options:
Some chips are warnings, not just damage. Call a professional (or at least investigate) before painting if you see:
If you live anywhere within a few kilometres of the coast (Cobh, Crosshaven, parts of Carrigaline, the harbour villages), salt air gets into exterior paint and accelerates chipping on woodwork. Sand back to bare timber, use a salt-tolerant primer, and budget for repainting exterior wood every four or five years rather than the eight or ten you’d get inland.
Older terraces in the city centre often have multiple paint layers built up over decades. If you’re chipping into a layer that looks chalky or powdery, stop sanding aggressively and read up on lead paint testing before going further. Pre-1980s paint can contain lead, and disturbing it without precautions is a real health risk.
If you’ve diagnosed and fixed the cause, a proper repair should last as long as the surrounding paint. If you’ve just covered the chip cosmetically, expect six to twelve months before it fails again.
Not recommended. Spray paint dries too quickly to blend into existing paint, and the texture is wrong for almost any wall finish. Stick with a brush or small roller in the same paint type and sheen as the original.
No. You only need to sand the chip itself and a small feathered area around it, maybe 5cm beyond the damage. Sanding the whole wall is overkill and removes paint you don’t need to replace.
For interior doors, a fine-grade wood filler or a two-part filler like Ronseal High Performance. For exterior doors, use a flexible exterior wood filler that can expand and contract with the timber. Avoid lightweight interior wall fillers, which are too soft and won’t take impact.
Almost always one of three things: you skipped the primer, you applied the paint too thick in one coat, or the colour has aged on the wall. Fix all three and most patches become invisible.
Repairing chipped paint properly is genuinely doable for most homeowners, but it takes time, the right materials, and a willingness to sand, prime and feather edges carefully. If the chip is in a high-visibility spot, on a large area, or if you’ve already tried once and weren’t happy with the result, sometimes the better move is to bring in someone who does this every day.
