Can these tiles be used outside on concrete patio?

You can use our 5/8" Premium Soft Tiles outdoors. Since these tiles are made from foam, they will not handle the elements as well as some of our other flooring products and may need to be replaced more often. They are non-porous and are mold and mildew resistant and are very easy to clean and maintain. These tiles are not UV stable, so over time in direct sunlight they will fade a bit.
