It is recommended for tiles to be site conditioned at room temperature for a period of 24 hours prior to installation. If tiles will be exposed to direct sunlight, it is ideal to allow the tiles to expand in the sunlight before installing. A minimum expansion gap of ¼’’ for 15.75″ tiles and ½’’ for all other styles should be left at the walls and/or any other immovable objects such as cabinets, vehicle lifts, support beams, etc.
