Yes, you can paint over peeling paint, but it is not as simple as just painting directly onto the peeling paint. You must take the necessary steps to prepare the wall first. Here’s my guide to painting primer over peeling paint:
- Step 1: Brush away as much of the peeling paint as you can; use a paint scraper to remove any more stubborn patches.
- Step 2: Use a high-performance sealant primer on the affected areas.
- Step 3: Once the primer has fully dried, use a filler to lightly coat the area.
- Step 4: Using an electric sander or just handheld sandpaper, sand the filler area down until the wall feels smooth and even to the touch.
- Step 5: Apply a second coat of primer over the freshly filled patch/patches.
- Step 6: Go in with the paint of your choice to match the rest of the wall, and apply two coats for a great finish.

Can I Paint Over Peeling Paint?
Peeling paint is the worst! I get it; as soon as you notice a section of paint that’s peeling, your first instinct is to quickly paint over it and hope that solves the problem. Unfortunately, that’s not the case.
Painting over peeling paint will only be a temporary fix, and within the year, you will notice the paint start to peel again. So, what are your options?
Removing it will require hours of scraping and sanding, not to mention annoying to destroy all your previous hard work sanding, priming, and painting in the first place.
The best solution would be to identify and remove the underlying issue causing your paint to peel, then seal the wall to stop the peeling and prevent future peeling. Then you can go in and repaint the peeled patch without having to worry about the issue coming back to haunt you.
Will Primer Stop Peeling Paint?
Primer is one of the most important steps in any DIY paint project. Primer is hailed as the magical healer of all paint-related sins. If you don’t sand your surface properly or at all, a good primer will have your back and make sure the paint still sticks to the wall nicely. Primers also help to block stains and give top coats a better, truer color.
But it’s actually not as simple as that. When it comes to painting interior walls, you can feel confident that whatever primer you use, your walls will be taken care of. However, exterior walls are a little more complicated and require a lot more thought when it comes to choosing the right primer.
If your exterior walls already have a peeling problem, this becomes even more important. Simply painting any old primer on them will result in a short-term fix, and eventually, you may be dealing with peeling paint again.
A lot of external factors will affect the lifespan of the paint on your exterior walls and cause peeling, such as harsh weather, including both wet and cold conditions and hot and humid conditions.
A good primer to go for to stop peeling paint is a Peel Stop primer. This is an exterior binding primer that is specially designed to stop paint from peeling, even on exterior walls.
It’s just as easy to use as other primers. You can apply it using any of the standard painting methods, including spraying. It can also be applied to most materials, such as wood and brick.
It works by getting into any cracks and under edges to seal the surface and stop further peeling and prevent future peeling.
Is Peeling Paint a Sign of Damp?
When moisture becomes trapped between a wall and the paint, it can cause the paint to bubble and/or peel. This is generally a sign of damp, in particular, rising damp. Ongoing damp issues cause paint and wallpaper to peel away from the wall, essentially because the moisture breaks the bond between the wall and the paint.
You will find paint peeling is particularly common in areas that see a lot of moisture and condensation, such as bathrooms and kitchens.
So it doesn’t necessarily mean you have damp in your home. Peeling paint may just be the result of condensation from a shower or bathtub, causing the paint on the walls to get wet over and over again.
If you do have a damp problem in your home, you can try to prevent it from causing the paint on your walls to peel by cleaning the area. Use a damp rag or sponge and wipe the area that has been affected by damp. It’s also a good idea to clean walls like this before painting to help prevent peeling issues in the future. Another good preventative technique is priming the walls before painting to further protect the paint from mold and moisture.
What Causes Peeling Paint?
- Poor Preparation – Before painting any surface, it’s super important that you prepare the surface material properly. Poor preparation can include painting directly on top of peeling paint or repainting without priming first. If the wall was not cleaned before painting, this could also cause the paint to peel. Additionally, using the wrong primer or paint can result in peeling too.
- Too Many Layers – Paint can become heavy if too many layers are applied. That is why it is generally recommended that we apply only two coats of paint for the ideal finish.
- Moisture and/or Damp – Water will break through the layers of paint, causing them to peel away from the wall. Water damage can be the result of any number of external causes, such as a leak, humidity, condensation, and poor ventilation.
- Dryness/Heat – Hot and dry environments stop paint from properly bonding with the wall when drying. Paint often peels in parts of the world that regularly experience hot temperatures because the heat dries out the paint, making it fragile and crumbly. Too much direct sunlight can also create this issue.
