They do make countertop paint kits made to resemble granite that you can apply to laminate counter tops if that is a possibility for you.

Here’s a link to one type of countertop resurfacing paint. They also carry similar items at Lowe’s.

Rustoleum has a paint I am going to use ... it comes in a multitude of colors and I've been told by those who've used it that it does a good job.

I do not think chalk paint would hold up on your counter tops--even if you put poly over it. I would use a paint kit for counter tops.

Good luck with that!
