Apply a bonding primer that is specifically designed to promote adhesion between oil-based and latex paints. A good quality primer I like to use is Stix. I also use this on my kitchen cabinets before painting them.
Acrylic/Latex paint will not adhere to oil based paint, unless you sand it down or use a latex primer that is 100% acrylic and has high adhesion. Or you can use an oil primer and then 48 hours later paint over that with a latex paint.
When covering oil-based paint with latex or water-based paint, you cannot paint directly over it. You must sand off the glossy finish, wash the surface with TSP, and prime it before painting it. This will provide a longer-lasting paint job and prevent the paint from peeling.
Latex paints will not stick to oil based paints. The exception is that an oil based primer may accept any kind of top coat paint. For that reason, an oil based primer is recommended to be applied over any oil based top coat, then a water based paint may be used as a top coat.
In this case you'll need to remove as much of the new paint as possible. Then you can use a water based primer with an adhesive like Gripper from Glidden. There are other brands of course, but an adhesive based primer will stay on oil paint or other surfaces that water based latex paint would peel off of.
If the paint does NOT come off, it is oil-based paint and you will need to prime the surface with a bonding primer before applying latex paint. The primer can be latex, but it has to be a product that is made to prepare the surface and help with adhesion and that says “bonding” on the label.
Prime the Surface with a High-Quality Primer
Priming is a critical step that can significantly improve paint adhesion and we recommend you use a quality sandable primer. A high-quality primer will provide a uniform surface for the paint to adhere to, improving both the appearance and durability of the final coating.
Use on interior and exterior surfaces including woodwork, drywall, plaster, paneling, masonry, brick, painted metal and properly prepared glossy surfaces†. Use under or over water-based or oil-based paints.
Applying layers of paint
Start by adding areas of shadow and light, fill in large areas with color, then work patiently, laying on more and more intense layers of color. You need to follow the golden rule of oil painting: painting "thick on thin" .
The glossy surface of oil-based paints makes it so difficult for any other paint to bond. That's why, if you apply water-based paint straight to oil-based, it will flake and crack as the water-based paint pulls away. So, to get oil-based ready to paint over, you need to take away a lot of that gloss.
If you have various stains, shellac Bonding primer is the ideal choice. It can be used to cover rough surfaces and old varnish as well as metal and ceramic.
Always start by painting the ceiling, move on to the walls and finish with baseboards. Leave any windows or doors for last.
Latex paint won't stick to oil-based paint and will eventually peel off, as shown in the picture above.
Peel Stop® tightly bonds to old paint and problem areas forming a sound surface for new paint. Peel Stop® forms a tough acrylic film that stays flexible and helps prevent peeling by letting moisture escape. A clear sealer, Peel Stop® works like nothing else to stop peeling problems on old or new surfaces.
Interior | Premium Stainblocking | Paint and Primer in One. Our most technologically advanced paint and primer in one, KILZ® Tribute® is 100% acrylic, low VOC, and offers both excellent stain-blocking performance and exceptional durability.
If you put latex paint over oil, you'll end up with that fruit roll-up look all over your house because they just can't adhere. Since they're not compatible, they won't form a good bond.
“If you are looking for a primer that can stick to almost anything for both interiors and exteriors, Stix® has you covered.”
We recommend KILZ KLEAR® Clear Sealer & Bonding Primer – a high performance fast-drying, multi-surface clear primer developed to seal highly porous surfaces inside and outside your home. It is also recommended for use when painting the same topcoat paint color on top of an existing paint coat.
Painting and Staining
The acidic qualities of the vinegar will clean and degrease the surface and help the paint adhere. Odors: When applying paint of any kind, keep small dishes of vinegar around the room to absorb paint odors. Keep the dishes out for a few days, adding new vinegar each day.
Lightly sanding the surface helps to remove any existing gloss, roughen the surface slightly, and create a better bond for the adhesion spray paint. Additionally, applying a primer or sealer to the surface further enhances adhesion by providing a suitable base for the adhesive paint.
The only reason that ALL-IN-ONE Paint does not adhere is if there is oil/grease or a chemical present on the surface before you painted. Things to look at: what did you clean with? Soap & water isn't going to cut it. You need a chemical degreasing agent.
You can use a latex primer over oil-based paint as long as it is a bonding primer. Bonding primers are best because they are formulated to adhere to glossy surfaces, such as oil-based painted finishes.
In order for your new paint to form a good bond with the existing paint, it's important that the two paints are compatible. Don't apply oil-based paint over latex; but you can put latex paint over oil-based, as long as you prepare the surface properly first.
Firstly, when painting with oils, it is important to adhere to the three rules of oil painting. These are 'fat over lean', 'thick over thin' and 'slow-drying over fast-drying'. This means that each layer of paint should be progressively more flexible, thicker and slow drying than the one below it.
