You can put water based/latex paint or primer over oil based. Its not recommended to do the other way around do the flex of the latex.
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.
After priming, allow to dry 4 hours, test a small area for bleeding by applying the topcoat before painting the entire project. If the stain bleeds through, apply a second coat of primer and allow to dry overnight and retest before topcoating. Use Multi-Purpose Latex Primer over solvent sensitive stains.
You can paint with water based paint over oil primer! That's fine because the primer finishes flat and the latex can grip to it.
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.
Do not thin. Stir thoroughly before and occasionally during use.
It's recommended to wait at least 24 hours before adding a coat of paint over your primer. Painting over it soon could cause your paint to adhere to the wall improperly, flaking and peeling.
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.
Oil-based primers permeate wood more comprehensively compared to latex primers, making them ideal for getting ready weathered wood for painting. The best permeation is attained by a slow-drying primer, however, the price to pay is an extended wait period before doing the topcoating.
May be used under and over any oil or latex architectural paint. The dried film is mold and mildew resistant.
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.

Water-based primers work well on ceilings, interior walls, and exterior surfaces for new projects. On the other hand, oil-based primers offer better performance on surfaces that require more durability and stain-blocking capabilities.
Waterbased paints can be applied over solvent-based paints, provided you prepare the substrate correctly. Conversely, we prefer to be a little more cautious. Although you may read here and there that it is possible, we would rather not recommend painting with solvent-based paint over water-based paint.
Priming makes sure the paint sticks to the wall better. A quality bonding primer, such as UMA®, can be used. You can also use an oil-based primer such as Ben Moore Fresh Start. Avoid water-based primers!
Under optimal conditions, these BEHR® primers listed below are ready for topcoat after one hour. Once completely dry, apply one to two coats of the desired BEHR water-based topcoat. Allow two hours of dry time in between coats.
Sanding the primer before painting is not just a recommendation; it's a critical step in the preparation process for painting a car. Skipping this step can lead to a less than satisfactory finish and potentially compromise the paint's durability and appearance over time.
Natural bristle is the best choice for oil-based paints, varnishes, shellac, alkyd enamels, oil stains and oil-based polyurethanes. The highest quality bristles come from mainland China. Experienced, traditional painters will say there's nothing like the finish that a China bristle can provide for oil-based coatings.
Depending on the brand, oil-based primers can take about 30 minutes to 4 hours to dry. Shellac primers can be used to cover water or smoke stains and inhibit odors.
Technically, yes, you can do that. Some circumstances don't require sanding the existing paint and primer before repainting. If you choose this route, the car's surface might show minimal damage like puncture holes, body scratches, dents, and cracks.
It's ready to brush, roll or spray and can be topcoated after one hour with latex or oil-based paint. Use KILZ STANDARD Primer on almost all interior surfaces including wood, drywall, plaster, brick, masonry and more. Not recommended for flooring, glossy surfaces, mold and mildew prone surfaces or for stainblocking.
You can use turpentine, white spirit or paint thinners to thin down oil-based paints for use in a spray gun. The best ratio for oil-based paints is 3/1. That's three parts paint and one part thinners.
Depending on how strong or bold the previous color is, it may be necessary to apply more than one coat of primer. However, it is not necessary to over apply the primer with so many coats. As long as the primer applies uniformly over the previous color, then one or two coats should be sufficient.
