Tile Paint Preparation

• First, you will need to remove the old layer of paint from your tile. It is the bond between the tile and this old layer that is causing the problem, covering it up with another coat will do nothing to stop the peeling and you will end up wasting paint. In order to remove the old layer of paint, use a paint scraper or scrubbing brush to tackle the peeling layers.
  
  

Scarify

• Scarify refers to sanding down the tile surface. Porcelain and ceramic tiles have glazes on them that prevent paints from working on the tile surface. This is a major reason that paints flake in the first place, and if you try to add a new coat with the glaze still there the same problem will occur again. Use a buffer or sander to remove the finish on top of the tile surface and fully roughen it. This will render the tile surface into something more like stone or concrete.
  
  

Cleaning

• When you are finished removing the surface of the tile, carefully clean the entire area. Remove all dust with a vacuum cleaner and ensure that no dirt or grime is left to interfere with the new paint-bonding process. You can use denatured alcohol to remove any traces of oil or dirt that's present, although a detergent should be sufficient for simple cleaning.
  
  

Types of Paint -- Primer and Gloss

• When you start painting the tile, use a tile primary first. These are paint primers that are designed to go over tile surfaces and prepare them for the next layer. Gloss paints are the most typical for tile surfaces, and do not be afraid to add more than one coat to ensure the paint layer looks smooth and natural. Because the glaze is gone, you should also put a sealant on top of the paint layer to protect it from moisture damage.
