Latex paint over Oil Paint


This has probably been rehashed many times but I cannot find it by searching, so here goes:

The kitchen cabinets are painted with oil based paint and it is time to freshen them up. With oil based paint becoming more scarce, is latex based paint proper?

Can Latex paint be painted over oil based paint if sanded or deglossed?

Should a protective clear coat be done over the Latex paint?

Am I missing anything?

Not regular latex. You need a good acrylic enamel. Industrial grade acrylics fit the bill pretty well here and there are some coatings designed just for cabinets.

Can Latex paint be painted over oil based paint if sanded or deglossed?

It can but depending on the products used you may have peeling problems. I've only come across a couple of products I'd recommend to do this way with no worry of peeling. You are probably better off sanding the finish and priming with oil based primer. You can top coat with acrylic and keep using acrylic from that point forward.

Should a protective clear coat be done over the Latex paint?

No. Paints are not meant to be clear coated this way.

Am I missing anything?

Probably, but it's too early here for me to think of anything else right off.

If at all possible, it would be better to paint again with oil,especially kitchen cabinets. That said, yes they can be painted with latex, with proper prep and primer.
Protective clear coat is not recommended.

According to the folks at SW, you must use an oil-base primer and can then use a latex paint over the o/b primer. If you use a latex primer over the o/b paint, you'll end up with peeling problems.

Because the latex is water based and will not adhere to the oil base paint.

That is odd, because the guy at my local SW told me that I could just degloss the oil coat, then paint right over it with latex. That statement is what started this thread for me, because I had heard the oil based primer and then the over coat of what ever was desired.

Otherwise there are bonding issuse between the latex (primer/topcoat) and the oil base.

I was just told this last week by SW in Huntington, WV. I hope they told me correctly.

I am afraid that deglossing is not enough. You really need to make the transition from oil to Latex with an oil primer.

The oil primer is the best way to do it. Will other methods work? Sure they will. I've sold a ton of 1-2-3 over the years to people too lazy to properly prep oil trim for a latex top coat. I've never had anyone complain that it doesn't adhere. It can work just fine, but you are taking a greater risk that it won't work and you'll have a mess to clean up.

I wouldn't lose sleep over using water-base bonding primer. The SW PrepRite ProBlock Latex is a bonding primer labeled for this use. I wouldn't use just any primer, but a quality product labeled for this should do okay.

I have used it in the past with nary a chip, anywhere, when combined with SW ProClassic Waterbourne.
