A top coat to make paint stick?
 
I just painted my old bathroom cabinets and when I was putting the hinges and knobs on I noticed how easy it was for my fingernail or screw driver to scratch off the paint. I lightly sanded each cabinet before I painted too. Is there some kind of top coat that I can apply that will help this not occur?

What was the paint you used? Some are MUCH better than others for cabs.
Also- it take a while (sometimes weeks) for a paint to cure to full hardness.

But it its hard to make a paint stick better by putting something on top- what is underneath, and what the paint itself is is what makes the difference.

Most of the time for cabinets, you need a BONDING primer like Zinsser's Cover Stain before applying a topcoat. The primer BITES onto the surface and gives a substrate that will accept the topcoat(S). I agree with BrushJockey that some paints are better than others at "sticking" to cabinets. I prefer SW's Proclassic waterbourne. Used it on some cabinet doors in the library area of my home and 10 years later they look great........beat up a bit, but still looking good.

Acrylic and vinyl semi gloss paints take a minimum of 30 days to cure.

You can put on a second coat to build up the film thickness or a clear water-based poly over them once cured with possible good results but as mentioned, if there is nothing under the paint to adhere to like a good primer, top coating is not going to help much.
