Gloss paint typically peels off because it has lost its adhesion to the surface beneath it. This is almost always caused by improper surface preparation (like skipping sanding or cleaning), painting over incompatible paint types (like applying water-based paint over old oil-based paint), or trapped moisture.
How to fix peeling paint
Fixing a peeled paint spot requires five simple steps: scrape away loose flakes, feather the edges with sandpaper, apply a special "peel-stopping" primer, patch with spackle, and repaint.
Painting over existing gloss (paint with a high-shine finish) is totally doable, but you cannot paint directly over it. Because gloss is slick and designed to repel dirt, new paint will slide right off. You must prep the surface by cleaning, sanding (or using a deglosser), and priming.
No, painting over flaking paint will lead to poor adhesion and more peeling. Always remove it first.
You cannot paint directly over peeling paint. The most important step is to first scrape away all loose flakes, sand the edges smooth, and apply a specialized binding primer—such as Zinsser Peel Stop or Sherwin-Williams PrimeRx—to lock down the edges.
Poor paint adhesion can manifest in several ways, including cracks, flaking, peeling, and other forms of paint failure. For example, if a wall is not properly cleaned before painting, the paint may fail to adhere and begin peeling within months.
Painting glossy surfaces—like laminate, glass, ceramic, or previously painted oil enamel—requires either thorough prep or specialized products. To get paint to stick without peeling, you can apply a high-adhesion bonding primer first, or use a multi-surface "all-in-one" paint designed to bypass sanding.
Red is universally considered the hardest paint color to cover. Vibrant red pigments are highly transparent and inherently prone to bleeding through subsequent layers. Other notoriously difficult colors to cover include black, dark blue, dark green, and bright yellow.
Allow a minimum of 6 hours for the undercoat to dry before applying the gloss finish. Where a second coat of Dulux Trade High Gloss is required, allow a minimum of 16 hours between coats.
Start by scraping off the excess dried paint then rub down your area with a low grade 100 sandpaper to ensure a flat surface. We recommend you then apply a layer of filler like Toupret wood filler to fill the peeled spot. Add a coat of Zinsser Peelstop to help seal the peel and paint 2 coats of your chosen topcoat.
Adding baking soda to paint thickens the mixture and gives it a heavy, gritty texture. It transforms standard acrylic or latex paint into a matte, chalky finish that resembles plaster, concrete, or rustic pottery. It also increases the paint's opacity.
Paint peeling is almost always a failure of adhesion, where the paint film loses its grip on the underlying surface. The root causes typically fall into three categories: trapped moisture pushing the paint off from behind, inadequate surface preparation, and material incompatibility.
Using a scraper or 100-grit sandpaper, remove any loose, cracked, or peeling paint from the damaged area. Remove any dust or debris from the area with a water-dampened rag. Using a putty knife, apply a thin layer of patching material to the damaged area. Allow it to dry.
There are several reasons that gloss work peels the most likely and one that I see often is due to the surface not being prepared properly. It is likely that whoever painted last painted water-based gloss on solvent based gloss without using a suitable primer/undercoat first.

Yes, you can do two coats of paint in one day, provided you use water-based (latex or acrylic) paint. Most latex paints dry to the touch in 1-2 hours and are ready for a recoat within 2-4 hours, allowing you to safely layer them without peeling or pulling up the first coat.

The ultimate sign of a bad painting job is peeling or flaking paint. This can happen if the surface wasn't properly prepared prior to painting, if the wrong type of paint was used, or if the painter didn't apply enough coats of paint.
