If applying water based paint over oil based paint, an oil based primer like Kilz Original works well. Even though the primer is oil based, it's designed to bond to water based paints. I've used Kilz oil based primer in the past to paint over wall paper and varnish and polyurethane for great results.

Keeping this in consideration, what kind of primer should I use over oil based paint?

To prevent peeling and chipping in the drying and curing phase, use bonding primer—formulated to stick to glossy and other hard-to-paint surfaces—over the old oil-based coat for optimal paint adherence. Apply one to two coats of an oil-or water-based bonding primer and dry according to product directions.

Also Know, does oil based paint need primer? 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.

Considering this, can I use a latex primer over oil based paint?

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. Apply a coat of a quality bonding primer (oil-based or latex), and allow the primer to dry. Topcoat with two coats of high quality latex paint.

What happens if you paint latex over oil?

Why Oil Paints Don't Mix Furthermore, if you were to use an oil paint over latex, the new paint will expand and contract at a different rate than the underlying layer, causing it to crack. Latex will not properly stick when applied directly on top of an oil-based layer without preparation, and may easily crack or peel.
