Out Nitro Tiles can be used outdoors. The tiles are resistant to UV but can fade slightly from constant exposure. These tiles are mold and mildew resistant and are also slip resistant when wet. These tiles are very easy to clean, maintain, and install. If there is not constant sunlight across the whole flooring surface, you may experience some buckling in the areas that do have direct sunlight constantly. If you do run into this issue, we recommend installing our vented patterned tiles.
