I also have plastic wall tiles in my kitchen and I like the idea of the metal tiles. I may do that right behind the area where my stove is to catch any grease that flies up. I also have a kitchen nook with a diner seat so that may be a great idea right in that area too. But I do want to paint the rest of the tiles.
What is the best paint and what do you use to paint with? Can I use a semi-gloss paint and smooth roller? Or should it be gloss? Is a roller alright or a foam brush?
