1
Clean the ceramic tile with a mildly-abrasive bathroom cleaner to remove any residue like dirt, oil or grease.
2
Plan out your tile designs. It may be helpful to sketch out your plan on paper. For those who are not artistically inclined, using stencils provides a way to create shapes and patterns.
3
Paint the designs onto the tiles using high-gloss acrylic paint. Use fine-tipped brushes for small tiles and intricate details. If you're using a stencil, attach it to the tile beforehand using small pieces of painter's tape in each corner.
4
Wait two to three days for the paint to adequately dry. Avoid touching the paint in any way during this time.
5
Paint a coat of water-based urethane over the entire surface of the tile. Urethane finishes seal in the paint so the design holds up to wear and tear. Once the coat is dry, add a second one.
