There are 3 ways to make oil-based paint over oil-based paint.
- Paint directly with oil-based paint: You can paint oil-based paint directly over oil-based paint. If the paint is not too dirty and there have not been too many coats on it before, there is no problem in applying oil-based paint directly on the oil-based paint.

There are 3 ways to paint water-based paint over oil-based paint.
1-Apply Transition Primer
A transition primer is a primer that allows paint to adhere to shiny and slippery surfaces. For this reason, a transition primer is the best way to apply water-based paint over oil-based paint. Apply 1 coat of the transition primer on the oil-based paint and let the primer dry for at least 5 hours. Then apply 2 coats of water-based paint at least 4 hours apart.
2-Sand It
Sanding creates slight roughness on the oil-based paint. This helps the water-based paint to adhere to the oil-based paint. However, the sandpaper should be fine to get a smooth surface. For large areas, you can use a sanding machine.
3-Use General Purpose Primer
If you cannot obtain a transitional primer for water-based paint over oil-based paint, you can use a general-purpose primer. To guarantee the result, you can lightly sand the surface of the oil-based paint before priming.
