QUESTION

Floor Rating - Is there a "rating" for ceramic tiles and does the rating really matter for my project? One store told me the rating is 1 through 5 with 5 being the best.

ANSWER

ANSWER - There is a PEI rating for glazed ceramic tile that goes from 1 to 5. 1 is wall application only, 2 is light traffic floor use i.e. residential bathroom, 3 is all residential use, 4 is light commercial use, 5 is heavy commercial use, and 5+ is extra heavy commercial use. The rating has to do with the wearability of the glaze surface.
