Step One: Time for the prep work! Clean your tile thoroughly with a heavy duty tile cleaner. Pick a cleaner that is abrasive.
Step Two: Assess the condition of your ceramic tile. Repair any grout or chipped tile if need be.
Step Three: Next, it’s time to remove that slick coating so the paint has something to adhere to. Use your orbital sander (if you have one!) or 220 grit sandpaper.
