This tile BBQ was nicely done, however the adhesive failed in our high temperatures and needed to be re-built. We first numbered all the pieces before removing & cleaning them up. Next the subsurface was scraped clean and made level. The same tiles were re-installed with new ones cut to fit where needed. Finally Mapei Flexcolor grout was applied and the area cleaned up. A great looking cooking center once again just waiting for the grill & some steaks!
