On the other hand, you can use latex paint over oil-based primer, but proper preparation is essential. Before applying latex paint over oil-based primer, make sure to sand and clean the surface thoroughly. This will create a suitable surface for the latex paint to adhere to.
Yes, using latex over an oil based primer is fine! Sounds like you have preped the previous painted surface well, so over it up with your oil base primer and you're good to go... with you BM Impervo!
Yes, latex over oil base is fine as long as the oil base paint is 'dull' enough to allow good adhesion. Oil base over latex is not so good since latex paint is soft and will flex and oil base is hard and will crack.
In addition, water-based paint is preferred when covering an oil-based product because it has a faster drying time and resists fading in the sunlight for exterior applications.
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.
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. 15-30 days after painting, you'll even be able to peel that paint right off after getting the surface wet. Yikes!
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.
Latex primers are water-based and ideal for prepping unfinished drywall for painting. They are more flexible and fast drying, and are less brittle than oil-based primers, making them less susceptible to peeling and cracking.
You can paint acrylic over oil paint pretty easily actually. All you have to do is follow the 7-step process in this blog post!
You can use any paint over oil-based paint as long as you use the right technique and primer. Always remember that oil and water paints will not adhere together. So, you must follow extra steps to make these two paints compatible.
Oil-Based Primer - These primers work with both oil paints and latex paints for interior and exterior paint jobs. Oil-based primers are great for blocking stains and are preferred for porous surfaces like wood.
May be used under and over any oil or latex architectural paint. The dried film is mold and mildew resistant.
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.
High Exposure to Sunlight. Exposure to intense sunlight makes oil-based paints vulnerable to cracking. Elastic and latex paints tend to contract and expand when exposed to direct sunlight, which weakens their adhesive bonds.
KILZ ORIGINAL INTERIOR/EXTERIOR Primer has excellent adhesion and penetration to bare wood. It also dries quickly and provides a mildew resistant coating. It can be used under water-based or oil-based paint. Not recommended on flooring.
Yes you can. You have two choices to do this. First would be to wash the surface, sand and then clean the sanding dust off. You may then apply your latex paint over the oil base paint.
Latex Over Oil: Yes, with Proper Prep
On the other hand, you can use latex paint over oil-based primer, but proper preparation is essential. Before applying latex paint over oil-based primer, make sure to sand and clean the surface thoroughly.
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.
When the oil-based primer is completely dry, the surface may still have a few small imperfections. This is typical even if you are a pro. The surface may feel chalky or even slightly rough. Using a Sanding Sponge, lightly sand the entire surface.
It's important to note that Zinsser Cover Stain is an oil-based primer, which means it has a strong odor and requires proper ventilation during application. Additionally, if you're planning to apply latex-based paint over Cover Stain, make sure to allow the primer to dry thoroughly before applying the paint.
Most acrylic and oil-based primers will accept both acrylic and oil-based top coats. For example, acrylic paints can be used over oil-based primers. If your project surface has an existing oil-based top coat and you would like to repaint it, either use another oil-based top coat, or the appropriate bonding primer.
No, you should not paint latex over acrylic. In fact, painting latex over acrylic can cause significant adhesion problems.
The best way to proceed is to apply a high end primer over the oil based paint before covering with latex. The sanding is only needed of the oil based paint has a gloss or shine to it. You only have to rough up the surface to give it some tooth to hold onto the next layer. But definitely follow sanding with priming.
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.
Oil over acrylic is fine with certain caveats, but acrylics over oil paints and oil grounds should be avoided. Oil paints form tight, water-resistant films that provide poor adhesion when acrylics are painted on top of them. We recommend avoiding this combination.
