Have you successfully used ceramic tile for outdoor patio? My concern is will the color fade?
Not ceramic, but we have porcelain tiles on our outdoor decks which are cantilevered out & away from the house, one on the 1st floor and the other on the 2nd floor. Porcelain is a little bit more expensive, but you can find it sometimes at tile centers on sale. If you crack porcelain the color runs all the way through, unlike tile that will show white underneath. Also, porcelain is less likely to crack in the weather conditions. I would not recommend slate for the above reasons as well. I checked with numerous tile distributors and installers before deciding against ceramic and for porcelain. It’s beautiful and we love it!
