It’s not uncommon for paint to start peeling off latex paint surfaces. Peeling can be caused by a number of things, such as improper painting techniques, using the wrong type of paint, or failing to properly prepare the surface before painting. Whatever the case may be, peeling latex paint is unsightly, so you’re probably wondering if you can paint directly over it.
You can paint directly over peeling latex paint if the peeling is minor. If you’re dealing with major peeling problems, you’ll want to first sand off the excess latex paint before painting over it.
In this article, I’ll go over the circumstances of when you can paint over a previously painted surface, the different types of paint you can use, and the best practices for repainting. I’ll also cover how to sand off peeling latex paint, in case you’re dealing with excessive peeling. Keep reading to fix those unsightly peeling spots once and for all!
Step-by-Step: How to Paint over Latex Paint
It’s actually pretty common for latex paint to start peeling, especially if it wasn’t applied correctly in the first place. You shouldn’t worry if you find yourself in this situation–painting over peeling latex paint spots is quite common.
You’ll need to follow some steps to make sure that you prepare your surface properly. Whether you’re painting over latex paint that’s peeling or not, there are some basic steps you’ll need to follow in order to get a smooth finish.
Here’s detailed guide on how to do it:
- Cleaning the surface. Start by giving the entire surface a good cleaning. This will remove any dirt, dust, or grease that could prevent the new paint from adhering properly. Keep in mind that latex paint won’t stick to dirty surfaces, so don’t gloss over this step!
- Sanding the surface. If you’re painting over an existing coat of paint, you’ll need to sand down the surface first. This will create a smooth surface for the new paint to adhere to. Check out the section below for a more detailed guide on sanding off paint.
- Applying a primer. Once the surface is clean and sanded, you’ll need to apply a primer. This will help the new paint to stick to the surface and will also provide a good base for the new paint color.
- Painting the surface. Once the primer is dry, you can then proceed with painting the surface. Just make sure to use a paint that’s compatible with the primer you used.
Following these steps will help to ensure that your new paint job looks great and lasts for many years to come.
With any painting project, it’s always best to consult with a professional before proceeding. They can assess the condition of your latex paint and advise you on the best course of action.
How to Sand Down Your Peeling Surface
If you’ve never sanded down paint before, do not worry. This step is actually a lot simpler than it sounds, but you will need to gather some supplies before you begin. Some of the things you will need for sanding off a peeling paint coat include:
- Sandpaper (coarse, medium, and fine grits).
- Vacuum cleaner.
- Tack cloth.
Once you have your supplies, follow these steps to sand down the surface:
- Start with coarse sandpaper. Use coarse sandpaper to remove any loose paint or debris from the surface. How rough or gentle you need to be depends on the surface you’re sanding the paint off of.
- Switch to medium sandpaper. Once all of the loose paint has been removed, switch to medium sandpaper and sand the entire surface.
- Finish with fine sandpaper. Finally, use fine sandpaper to create a smooth, even finish.
- Vacuum the surface. Once you’re finished sanding, use a vacuum cleaner to remove all of the dust from the surface.
- Clean with a tack cloth. To remove any lingering dust particles, wipe down the surface with a tack cloth.
And that’s it! You’re now ready to apply primer and paint to the surface.
Keep in mind that sanding can be a time-consuming process, so it’s important to allow yourself plenty of time to do it right. Also, be sure to wear a dust mask while sanding to avoid breathing in any harmful particles.
If you don’t feel comfortable sanding down the surface yourself, you can always hire a professional to do it for you.
Can You Paint Over Peeling Latex Paint With a Different Type of Paint?
If you’re wondering if you can paint over peeling latex paint with a different type of paint, the answer is yes! You can use oil-based or water-based paint over peeling latex paint.
The main thing to keep in mind is to make sure that the new paint is compatible with the old paint. For example, you wouldn’t want to use a water-based paint over an oil-based paint, as this could cause the new paint to peel.
It’s always best to consult with a professional before painting over any type of surface, especially if you’re not sure what type of paint was used originally.
When to Paint over Peeling Latex Paint
When it comes to painting over top of peeling latex paint, there are some tell-tale signs that will help you know whether or not you can apply your new coat of paint directly.
These include:
- The peeling paint is only in one small area.
- There are only a few areas of peeling paint.
- The underlying wall is in good condition.
- The peeling paint is not caused by a moisture issue.
If you can answer yes to all of the above, then you can go ahead and apply your new paint right over the peeling latex paint.
Just make sure to sand down the area first so that the new paint will have a smooth surface to adhere to.
If the peeling paint is caused by a moisture issue, you’ll need to address that before painting over top. Moisture can cause paint to peel for a number of reasons, including high humidity levels, leaks, or condensation.
If you’re not sure what’s causing the peeling paint, it’s always best to consult with a professional before proceeding.
When NOT to Paint over Peeling Latex Paint
In addition to moisture issues, there are a few other instances when you should not paint over peeling latex paint. These include:
- The paint is peeling in large areas.
- The wall is cracked or flaking.
- There is significant mold or mildew growth.
If any of the above applies to your situation, then it’s best to strip the paint off completely and start from scratch.
Trying to paint over large areas of peeling paint will only result in an uneven finish that will eventually start to peel itself. The same goes for walls that are cracked or flaking–any new paint will just end up cracking and flaking right along with the old paint.
And finally, if there is significant mold or mildew growth, painting over top will only trap the moisture in and make the problem worse.
In these cases, it’s best to remove all of the paint before repainting. This can be done with a paint stripper or by sanding down the surface.
Once all of the paint is removed, you can proceed with painting the surface using fresh paint.
What to Do If Your New Paint Starts Peeling
Even if you’ve repainted your surfaces with the steps described above, there’s always a chance that your new paint will start to peel. This can be caused by a number of factors, including:
- Poor surface preparation. If you don’t clean and sand the surface properly before painting, the new paint may not adhere properly and could start to peel. Latex paint needs a completely clean surface to adhere to, so a dirty or dusty surface will result in peeling latex paint.
- Incompatible paint. If you used a paint that’s not compatible with the primer, it could cause the new paint to peel. If repainting over peeling latex paint, you should stick to oil-based and water-based paint to ensure compatibility.
- Excessive humidity. If the air is too humid when you paint, it could cause the new paint to peel. Excessive humidity can result in peeling latex paint, even if you followed our instructions perfectly.
If your new paint does start to peel, you’ll need to strip off the paint and start from scratch. This can be done with a paint stripper or by sanding down the surface. Once all of the paint is removed, you can then proceed with painting the surface using fresh paint.
The Bottom Line
Overall, painting over latex paint that’s peeling can be done, but it’s not always the best option. If the paint is peeling in large areas or if there is mold or mildew growth, it’s best to remove all of the paint before repainting.
Following the steps that we outlined above, you should have no problem painting over latex paint that’s already peeling. Just make sure to take your time and do a good job for the best results!
In 2002 renovated our house. All new dry wall etc. painted by a professional company- spray primed and painted the rest “by hand”. Benjamin Moore latex paint. 2022 I am painting the house room by room. The first two rooms were bedrooms, and I primed both rooms as there was to be a drastic change of colour i.e. dark wall to white. My consistent prep for the all the surfaces is: clean the entire room – vacuum – then TSP wash, rinse with water, dry, lightly scuff , vacuum and then I cleaned (with damp cloth only), dry the walls again to remove any dust.
Two weeks ago my daughter came home and painted the ceiling. A week later I painted the closet in my son’s room – walls, ceiling, trim. The next day I went check my painting and missed a few spots on one wall so wanted to just paint that wall – I started to lightly scuff – and the paint started to come off in large sheets. Consult with two different Benjamin Moore paint stores – both told me oil paint – I know is NOT oil paint as I bought the paint 20 years ago but to satisfy them I did a wipe test with methyl hydrate and one with nail polish remover – I went all over the house in different rooms and different walls etc and the result the same for both products. paint on the cloth that should indicate latex – and I did larger areas not jus a Q-tip.
The only solution by both vendors was to prime with Zinsser Stain Killer Primer – an oil base primer that allows for painting with latex after dry. I did scrape as much paint off the closet as I could get off I have now primed the room – except for the ceiling my daughter painted as it seems fine and nothing will touch it.
So why can I not paint latex over latex? My sister and my cousin had the same scenario happen to them several years ago. Did I prep too much? should I have left at the TSP? Why does the painter company tell me not to scuff? And more importantly in these times of environmental concerns , has the latex paint changed enough in the last 20 years that it will act more like a oil based paint to the new latex paint? OR can you actually never paint over paint – unless fresh paint?
There is 9,000 sq ft of drywall in this house. So is a big job. Answers? Ideas?
