What is artisan tile? As if crafted by hand, the ARTISTIC TOUCH TILE collection features the one-of-a-kind look of handmade tiles with a slightly irregular edge, undulated surface and varied color tones. Can tiles be painted over? Most ceramic tiles can be painted, as long as it's not frequently subjected to water or heavy wear. ... Once dry, give the tiles a quick scuffing with sandpaper/abrasive cleaner to dull the surface gloss. Sanding or dulling is recommended on glossy, extremely hard surfaces for maximum adhesion. When painting tiles do you paint the grout? Just paint your tiles, wait for it to dry and apply the grout pen afterwards. There's no need to worry about painting over the grout, just apply your pen when the paint is dry. If you're going for intricate designs instead of a blanket cover, the same method applies. Paint first, then grout pen.
