If you want to repaint over old paint, you will first have to either remove any sealer or apply some primer to ensure that the new paint can adhere properly. But can you prime over peeling paint?
Truth is, you can’t. And it’s for a very simple reason. If you prime over peeling paint, you are essentially applying primer to an unstable surface that is coming off, and as it comes off, whatever you have applied over it will come off with it. Aka, the primer will also come off!
So priming over peeling paint will just be a waste of effort, time, and resources.
This doesn’t mean that you have to strip the entirety of the old paint. If the peeling paint isn’t too severe, you could simply brush away the pieces that are already coming off, and then prime the surface. Basically, as long as the surface is smooth and stable (with no pieces hanging off the wall about to come off), then you should be able to apply the primer. But if the peeling is too severe, then priming will not be viable, and will just be in vain.
Instead, you will have to fully scrape off and strip all of the old peeling paint off from the wall, so that you can start over with preparing the surface with some primer, without the risk of it peeling off as the old paint did.
Can I paint over peeling paint?
Old paint that has started peeling can’t just be painted over, as it would create far too many future problems. Peeling paint is unstable and is coming loose from the wall, meaning it is not a suitable surface on which to paint on, as the new paint will simply come off with it. On top of that, peeling paint causes the surface to have holes and cracks, in which dirt and moisture can seep into, causing even more problems such as cracks and damage. So covering all of this up with a new layer of paint will not solve the problem, it simply hides it away from view for a short amount of time, after which all of the effort, time, and resources will have been wasted in vain.
Instead, before painting over peeling paint, you have to fix the peeling paint. And by fixing, we essentially mean remove it.
Here is what to do, step by step:
- Start by using a paint scraper, or a similar tool, to scrape away all of the peeling paint. All of the loose edges that are already falling off should come away easily with minimal force. If you’re struggling to remove more paint, stop using the scraper. Too much force and you might damage the surface beneath.
- Use a brush to remove the remaining paint, along with all of the bits and pieces of peeled paint, dirt, and debris. Keep brushing until nothing is coming off the surface.
- Repair any damage done to the surface. This might include filling in cracks and holes with the appropriate type of filler products. Essentially, you need to ensure you end up with an even and smooth surface on which to repaint.
- Once the filler products have dried, use some sanding paper to sand down the entire surface for a smooth and even finish all around.
- Next, make sure to clean the surface thoroughly. Remove all of the dust from the sanding, and make sure there is no dirt or debris that might get trapped beneath the pain while repainting.
- Let everything dry. When painting, it is vital that the surface is 100% dry without any moisture or dampness, or else the new paint will end up with cracks. You should also double-check that everything is smooth and ready.
- Now you can apply the primer. Make sure to use the right type of primer for both the surface and paint that you are working with.
- Finally, once the primer has dried, you can begin painting the surface anew!
Will primer stop peeling paint?
As a general rule, if the paint is peeling off, then you cannot apply a primer because the primer will not stop the peeling, and will instead come off with the peeling, resulting in a waste of time, energy, and money.
Instead, the solution is to scrape and brush away all of the loose edges of peeling paint that is coming off, until you are left with a surface that is stable. This way, you make sure there’s no peeling paint, without having to fully strip away the old layers of paint before you apply the new primer.
But what do you do if the paint just keeps peeling? If the paint is particularly old, scraping away the loose edges won’t do much, because other bits of the paint will loosen and peel off not long after, and it can be a painful never ending process that would make primer completely useless.
The obvious solution would be to completely strip away all of the old layers of paint. And this can be a nightmare of a job, as it’s going to take a lot of effort, a lot of time, and the right products for the job.
But what if you don’t want to resort to that? Is there really no other solution?
Okay, fine. There is one other course of action: using a special type of primer.
There are primers that have been specially formulated and designed to be used over peeling paint, and they essentially not only prime the surface, but also help glue down the loose edges of peeling paint, so that the old paint beneath them stops peeling.
This type of primer is known as a binding primer, and it is the go-to for dealing with eternally peeling paint that you need to paint over.
Can you seal peeling paint?
You can seal peeling paint with the right type of primer. However, it is highly recommended that you first scrape off all of the loose edges of the peeling paint that is in the worst condition, as this can negatively affect the efficiency of the primer used.
