Hardening tile pain?

I have painted over my existing kitchen tiles. They look ok but are prone to scratch. Is there anything (like clear varnish maybe) that I can use as a final top coat

u could have used eggshell paint its hardy than gloss and gives a nice finish if its scratchy it need another coat paint. get clear vanish not water base one and u can wash it

go to you local car accessories shop and get a can of clear lacker this should do the trick (test on a small area first).
