Horrible tile! Do Not Purchase! Went from beautiful color to grey (seriously grey!) after one season outdoors! Extremely dissatisfied with this purchase. Complete waste of money. Photos not altered. First picture taken June 2019 just after installation. Other photos taken today April 25, 2020. I moved the deck box and grill mat to see what happened. How do I fix this?!?Apparently tiles were not sealed after staining and prior to shipping? Instructions never said I was to apply a sealant or top coat. I give this product zero stars!
