About 4 days ago, I painted my countertop with Rust-Oleum countertop paint, and they look great. My question is, I would like to put a coat of clear gloss polyurethane on it. Will there be any issues doing that, and if there are no issues, how long should I wait to do it.

Thanks guys.

As soon as possible. And you would be better off getting a product called table top epoxy.

Definitely put epoxy or some sort of clear coat. I used the same kit a few years ago. Looked amazing till about a year in when it started pealing/chipping. I just finished stripping it all back off this weekend.

Agreed!

A two component clear coat will last longer. Ask the Rust-Oleum people if they know what works best, not what they're told to sell, applied over your current countertop.

There was a similar post a couple days ago where the poster had issues with his topcoat never properly hardening. IIR the consensus was he didn’t let the countertop dry properly before he put the topcoat on.

Oil will yellow. Waterborne poly will be alright.
