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.
The best way to prevent paint from peeling is to properly prepare the surface before painting. This includes cleaning the surface and removing any loose paint or debris. You may also need to apply a primer to help the paint stick better.
Moisture and Water
Collectively, you can be assured that water is the number one cause of peeling paint issues. Even if water damage cannot be seen, moisture could still be wreaking havoc.
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.
If you are in a pinch, then PVA can be used as a barrier between peeling paint and a new coat of paint if you do not have a primer. The PVA glue will bind the edges of the peeled paint and provide a tacky surface for the new paint to adhere to once you have removed any large flakes coming away from the wall or ceiling.
Method 1: Use Spray Varnish
First, lay down some old newspapers or anything else to protect surfaces around your work area. Next, hold the can about 12 inches away from the painting and evenly spray the surface. Allow the first coat of sealer to dry completely before applying a second coat.
Well, an alternative to this drastic action is using a binding primer. A popular choice is Zinsser's Peel Stop, which is a water-based primer that penetrates chalky surfaces and helps to glue-down the edges of cracking and peeling coatings to the substrate so they can be successfully painted over.
Moisture. One of the main causes of peeling paint is the presence of moisture or water around the paint. This will usually happen when water gets into the wood behind the paint. This separates it from the wall and seeps through the layer of paint.
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.
Zinsser Peel Stop 1-gal. Water Base Clear Interior/Exterior Binding Primer and Sealer (Case of 4) glues down peeling paint and bind chalky surfaces. Designed to seal cracked and checked surfaces for durability, it helps provide a sound surface.
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 Stop® tightly bonds to old paint and problem areas forming a sound surface for new paint. Peel Stop® forms a tough acrylic film that stays flexible and helps prevent peeling by letting moisture escape. A clear sealer, Peel Stop® works like nothing else to stop peeling problems on old or new surfaces.
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!
Extreme dryness can prevent the formation of strong adhesive bonds that allow the innermost coating of paint to stick to the surface properly. Similarly to painting highly humid surfaces, extreme dryness causes any newly applied coats of paint to peel.

Peeling or cracking paint is not just unsightly—it can pose a safety hazard. As soon as you notice a problem, remove the peeling areas and start over with fresh coats of primer and paint.
The ability to paint over peeling paint largely depends on the underlying cause of the peeling. If the peeling is due to poor adhesion or surface preparation issues, it is generally possible to paint over it.
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.
Turns out, it's ok to leave primer unpainted in CERTAIN situations. But most of the time, it's not recommended because it doesn't offer the full protection and benefits of paint.
If the paint does NOT come off, it is oil-based paint and you will need to prime the surface with a bonding primer before applying latex paint. The primer can be latex, but it has to be a product that is made to prepare the surface and help with adhesion and that says “bonding” on the label.
Customers have mixed reviews about the product's ability to prevent paint peeling and chipping. Some say it works well for preventing peeling wallpaper and paint chipping, while others mention issues with cracking or shiny paint in cracks.
