You can paint anything you want to paint; the question is whether it will last.

The answer depends upon the surface of your countertops, but, generally, countertops are designed to be resiliant so that things do NOT stick to them. Thus, ordinary paint on typical formica countertops will scratch off within a week to the point where you will wish you did not do it. If any paint would work, you would need a specialty paint plus primer, plus you would probably need to scuff the surface to give the primer something to "bite" onto.

thax for ur help

There are companies that specialize in painting counter tops and that would be your best bet as opposed to doing it yourself as the chance for failure is very high if not done exactly correct.
