These sage green decorative tiles are super easy to use. First, clean the surface where you want to install them to make sure it's dry and smooth. Then, apply tile adhesive evenly on the surface and press the tiles firmly. Use tile spacers to keep the gaps uniform. When cleaning, just use a mild detergent and a soft cloth. Avoid using abrasive cleaners as they can scratch the tile surface. Store the tiles in a dry place to prevent damage.
