If you have ceramic tile outside that needs some updating, painting the tiles with a fresh coat of paint will renew the look for little money. Painting outdoor tiles allows you to improve the look of the exterior space without any messy demolition projects or frequent trips to the hardware store. If you are re-painting the exterior of the house, update any outdoor ceramic tile you have as well.
Clean the outdoor tile thoroughly to remove any build-up of dirt or grime. Mix oxygen-bleach with water according to package instructions, and spread out onto the tile and grout. The oxygen in the bleach will clean deeply, removing the dirt build-up. Allow the oxygen-bleach to penetrate the tiles and grout for 10 minutes.
Scrub the tile with a scrub brush, and the grout lines with a grout brush. The grout brush will remove the dirt without scrubbing it away.
Allow the floor and grout to dry for at least 48 hours before painting, as grout needs to be completely dry.
Paint over the ceramic tile in a paint colour of your choice. Choose a water-based paint with urethane resin to avoid the paint from peeling. The paint will also be tacky, so it sticks to the shiny ceramic surface adequately. Roll the paint onto the tiles using a low nap paint roller, so that it rolls on smooth with the minimum amount of texture.
Hang a tarp around the area to keep dust or debris from blowing onto the fresh paint. If you are painting a patio, hang the tarps off of the roof to create a room-like area until the paint is dry.
Allow the paint to sit for 48 to 72 hours to ensure it is completely dry and hardened before removing the tarp.
