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. It might also cause the new paint to start peeling prematurely.
No, you can paint over old paint, providing it is in sound condition and not peeling. If there is peeling paint or a cracked surface you must address those issues by scraping, sanding, and priming before applying a top coat of paint.

If the peeling is due to poor adhesion or surface preparation issues, it is generally possible to paint over it. However, if the peeling is caused by moisture, mold, or other structural issues, addressing the root cause is essential before applying new paint.
Get another painting support and start your new painting on a fresh surface. The most common solution is to cover the old painting with gesso as a method for starting over or perhaps changing a certain area of the composition. This is not a good idea for oil, or acrylic paintings. Gesso is a ground, it is not paint.
Applying the second coat too early will result in streaks, peeling paint, and uneven color. Not only will this ruin the entire project but it'll cost additional money to get more paint in some occasions. It's best to wait for the first coat to dry.
In painting, a pentimento (Italian for 'repentance'; from the verb pentirsi, meaning 'to repent'; plural pentimenti) is "the presence or emergence of earlier images, forms, or strokes that have been changed and painted over". Sometimes the English form "pentiment" is used, especially in older sources.
You probably don't need a primer. If the current wall is smooth, clean and covered with the same type of paint (both are oil-based for example), you can head straight for the paint. You need to fill holes, spackle and sand*, maybe even cut a new piece of drywall in to the existing wall.
Although the bacteria that grow in paints aren't going to be ingested, they break down the compounds in your paint, making it less adherent and leading to streaks and peeling.
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.
Some people choose to skip this important step, but they're missing out on some of the benefits paint removal provides. Both individuals and businesses have situations where they need to paint strip, and removing old paint gives you a fresh start and a more even new coat of paint.
It can be dangerous to use old paint. Paints made prior to 1978 may contain lead and expired oil-based paints can emit harmful fumes that are toxic. Even latex paints made prior to 1990 may contain mercury which is dangerous to you and your family.
Yes, you certainly can paint over painted walls, but not with just any old paint over any old painted wall. As long as the underlying paint is sound, you can paint over it, but to achieve a professional result, you'll need to know the specific factors that will give you a high-quality paint job.
Remember you do not need to remove all of the paint, just the damaged and flaking portions of it. Any paint that can just be peeled off needs to be removed as it is not bonded to the underlying layers sufficiently.
One gallon of Wall Paint will cover approximately 375-425 square feet. One gallon of Trim Paint will cover approximately 375-425 square feet. One gallon of Ceiling Paint will cover approximately 350-400 square feet.
Conclusion. To sum up, it is generally okay to paint over old paint as long as you prepare your surface correctly.
While you may not love the smell of fresh paint, spoiled paint has a scent that's much worse. "Paint that is beyond its shelf life can develop a rancid, sometimes rotten-egg odor," says Edrosa. If you open a can and find either of these problems, dispose of the paint and buy new.
The bottom line is that watery paint is unusable. So if your paint is too watery and you attempt to use it to paint your home, you will notice that the paint won't adhere to surface correctly. It will be 'thin' and therefore will perform poorer than expected.
Without primer, the paint absorbs into the surface unevenly, leaving an inconsistent finish with patched areas showing through the final coat of paint.
The good news is that you can paint old furniture, without sanding, and it comes out beautifully. I've painted about 8 or 9 pieces of furniture, and I've gotten better results with each one.
Do I have water-based or oil-based paint in my house? The test to determine whether your paint is oil-based or water-based is pretty easy. Simply put some methylated spirits on a rag and wipe at a small section of your wall. If the cloth is stained with the wall colour, it is water-based.

It's important to spread the paint evenly over the surface but with enough opacity to kill the original image. You can see how the ridges and bumps of the original painting disappeared under the creamy underpainting – the surface is still there but the image has gone.
