Flaking is the lifting of a brittle paint coating from the underlying surface in the form of flakes. Flaking can affect one or more coats. Flaking is a follow-on effect of cracking, where cracks in the paint film have allowed moisture to enter the paint system and compromise the adhesion bond.
It can also be caused by the use of an incorrect paint system, poor surface preparation or ageing of the paint system. Flaking is similar to peeling, but with the former the coating tends to be harder and brittle.
Remove all loose and flaking paint with a scraper or wire brush, sand the surface and feather the edges. If the flaking occurs in multiple layers of paint, use of filler may be necessary. Prime bare timber areas before repainting. Use of a premium quality primer and topcoat should prevent a recurrence of the problem.
Peeling paint is most commonly created when water gets under the paint. Therefore, the most common areas for peeling paint to occur are in the wet areas of a house or building e.g. bathroom, laundry or kitchen. However, there may be other issues with the premises such as excess humidity or a leaky roof.
Yes, with proper preparation, priming, and painting, peeling paint can be restored effectively.
Peeling or flaking paint isn't just an eyesore—it's often a warning sign of deeper issues like moisture damage, poor surface prep, or extreme temperature fluctuations. Left untreated, it can lead to further deterioration, exposing surfaces to mould, mildew, and structural weakening.
Peeling paint must be removed prior to applying a fresh coat of paint to ensure proper adhesion. For Best Results: Refer to the how-to for guidelines on removing peeling paint. Using a scraper or 100-grit sandpaper, remove any loose, cracked, or peeling paint from the damaged area.

Look for these water damage signs when trying to detect water damage in your ceiling: Peeling, bubbling, or flaking paint. Small hairline cracks or a larger, spiderwebbed pattern of cracks. Water rings, usually a light brown color.
Improper Painting Surface Preparation
The painting surface needs to be thoroughly prepared before the paint job is initiated. When the paint is applied on an unprimed or uneven surface, it will start blistering and peeling. Proper prep work is a must if you want to avoid this.
To avoid peeling paint, make sure to properly prep the surface beforehand. Take a damp sponge with a bit of dish soap and gently clean the area. Allow the surface to dry completely before adding your first coat of primer or paint.
The cause of flakes and particles in paint and lacquers.
New paints and lacquers dry quicker than before. Paint tends to stick to a plastic roller grid or plastic lid of wall paint packaging and dry. Flakes easily come off and fall back into the paint. And boy, do we hate hard particles in paint!
Over time, fluctuating temperatures and humidity levels can make paint peel. For spaces where this is normal like kitchens, using KILZ 3® Premium Primer (known for its exceptional adhesion and durability) before you paint can help ensure your paint job lasts longer.
Peel Bond is a great bonding primer that can be used when you need to apply a topcoat over a surface that you are concerned it may not stick to.
If the old paint is flaking, bubbling, or peeling off, it might not be a good idea to paint over it directly. This is because the new layer of paint might not adhere properly to the surface, leading to an unattractive and uneven finish.
It's best to scrape off peeling paint with something like a 5-in-1 tool, then go over the area with sandpaper. If you need to, use drywall compound or spackling to repair any holes, and sand the area again. Then, finish with primer and top coat.
If you have various stains, shellac Bonding primer is the ideal choice. It can be used to cover rough surfaces and old varnish as well as metal and ceramic.
Flashing, or 'the halo effect', is when patches become visible on a painted surface in certain lights/angles. Flashing appears when two areas of a painted surface have been applied differently. In the example shown below, the wall was originally painted using a roller and has since been touched up using a paint brush.
Give it a freshening if the paint looks dull or faded. Paint flaking or peeling can instantly ruin curb appeal and give the impression that the house has not been well maintained. Your home could contain lead-based paint if it was built prior to 1978. It will need to have the paint removed to satisfy your lender.
Discoloration or Stains
When mold has been painted over, it can start to show through the paint. It often looks like stains on the wall that take on a yellow or brown color. You'll likely notice these stains through light-colored paint or on the ceiling.
For earlier signs of damp, you might notice a musty smell or your walls could feel cold and wet. Another sign is discolouring or peeling of your paint or wallpaper. You might also find that plaster is fragmenting too. While excessive condensation isn't a guaranteed sign of damp, it can be a cause of it.
