Painting over alkyd enamel paint on wood doors....

ok so I tried painting a solid wood door that had alykd enamel semi-gloss paint on it. I sanded the door and wiped it clean with wet rags. Then used the CIL duo paint & primer in one as the new paint. The first coat went on and I let it dry for 24 hours. I noticed that I could in some areas scratch the paint off with my finger nail, I then applied a second coat of the same paint and let it dry for approx. 4 days. It now is alot more difficult to scratch the paint off but with enough pressure I can.

So my question how can I correct this....maybe another coat of paint? or, a light sanding and use an alkyd enamel paint over top?

These doors are in a doctors office so lots of traffic and some banging into as well....

Any thoughts?

Thanks in advance.

Welcome to the forums.

I don't know what the product is you said you used but I would have used a separate oil based primer (I prefer the Zinnser line) and then probably a latex or waterborne enamel paint.

At this point, I think I'd probably stop, it sounds like it's not that easy to scratch off the paint any more.

It's never a good idea to apply latex paint directly to oil base enamel. As Mitch said - it's best to sand and then apply a solvent based primer if switching to latex paint. Latex enamel does take a week or so to fully cure but I'd be leery that this paint job will fail over time.

I wouldn't advise applying oil enamel over the latex paint. To do it right, you really need to remove 90% of the latex and then either repaint with oil enamel or use a solvent based primer which can then be coated with latex or waterborne enamel.
