Flaking paint is one of the most common maintenance headaches in Greek homes, holiday rentals, and hotel rooms — Mediterranean humidity, sea air, and temperature swings all accelerate the problem. The video above walks you through the technique in real time, and the steps below give you the full method in a format you can follow room by room. Done properly, the repair is invisible and the new coat will stay put for years.
Why Paint Flakes in the First Place
Paint lifts and peels when it loses adhesion to the surface beneath it. The usual culprits are moisture penetrating through walls or ceilings, a previous coat applied over a dusty or chalky surface, or cheap paint layered over incompatible primers. In Greece, exterior walls that face north or are shaded for most of the day are especially vulnerable because they stay damp for longer after rain.
In rental properties the problem is often found in bathrooms, kitchens, and the underside of roof terraces. Ignoring it makes things worse: each flake that falls enlarges the loose edge and gives water a new entry point, turning a cosmetic issue into a structural one.
Tools and Materials You Will Need
You do not need specialist equipment. Gather a stiff scraper or filling knife, medium-grit sandpaper (around 80-120 grit) and fine-grit finishing paper (180-240 grit), a damp cloth, a small brush, a stabilising primer or PVA diluted 4:1 with water, fine surface filler, and your topcoat paint. For larger areas add a sanding block and a short-nap roller.
If the flaking is linked to active damp — a stain on the ceiling, a salt bloom on an exterior wall — fix the source of moisture before touching the paint. No amount of surface repair will last if water is still coming through.
Step-by-Step: How to Fix Flaking Paint
- 1
Remove all loose paint
Work across the affected area with a stiff scraper, lifting and removing every flake and loose edge. Do not be shy here — any paint that moves under moderate pressure will fail again once recoated. Feather the edges between the bare wall and the sound paint with medium-grit sandpaper so there is no abrupt lip. Wipe the surface clean with a damp cloth and let it dry completely before moving on.
- 2
Seal the chalky surface with a stabilising primer
Old, powdery plaster or masonry acts like sand under a new coat — nothing bonds to it. Apply one coat of a diluted PVA bonding primer (or a dedicated stabilising solution) and let it penetrate the surface. This consolidates the substrate and gives the filler and topcoat something solid to grip. Allow full drying time, which is typically 1-2 hours, before the next step.
- 3
Fill, sand, and feather
Mix a fine surface filler to a smooth, lump-free consistency and press it into the scraped-back area with a filling knife, drawing it slightly proud of the surrounding surface. Let it dry fully — rush this step and the filler will shrink and crack. Once hard, sand it back flush with 180-grit paper using light, circular strokes. Run your palm over the patch: it should feel even with the wall around it. Wipe off all dust.
- 4
Apply a mist coat or undercoat
A mist coat is emulsion thinned 10-20% with water, brushed or rolled over the repaired patch (and ideally the whole wall in a rental or hotel context). It soaks into the filler and creates a uniform, slightly porous base so the final topcoat goes on evenly without flashing — the patchy sheen that appears when fresh paint sits on top of an unprimed filler spot. On masonry or heavily repaired areas, a dedicated wall primer does the same job.
- 5
Apply topcoat paint in two thin coats
Roll or brush on the first topcoat using smooth, overlapping strokes, and let it dry fully before adding the second. Two thin coats always outperform one thick one: the paint levels better, cures more evenly, and resists future peeling. In bathrooms and kitchens, choose a moisture-resistant or kitchen-and-bathroom formulation; for exterior facades in Greece, use a breathable masonry paint rated for high-humidity climates.

FAQ
- Can I paint directly over flaking paint to save time?
- No. Painting over loose paint traps the problem underneath and the new layer will peel again within months, often taking more paint with it. The only lasting fix is to scrape back to a sound surface first.
- How long does a flaking paint repair last?
- If you remove all the loose material, seal the substrate, and use a quality topcoat, the repair should last 5-10 years. Repairs in damp-prone areas like bathrooms will last closer to 3-5 years unless the underlying ventilation issue is also fixed.
- Is flaking paint a sign of something more serious?
- Sometimes. A single small patch is usually just age or a poor previous coat. But widespread or recurring peeling — especially with staining, salt crystals, or a musty smell — points to active moisture ingress from a leaking pipe, rising damp, or a failing waterproof membrane on a terrace above. In that case, get a damp survey before repainting.
