According to my knees, I’m finished with the grout portion of the program.
I applied Mapei brand “warm gr(e)y” Keracolor S grout, hoping that it wouldn’t argue with the 12-inch Glacier Bay “Arctic Blue” porcelain tiles I had set into Mapei Ultracontact full-contact mortar. The application went well, and the clean up really only required a solid block of time and lots of elbow grease.
The floor has a few issues, but in general I’m pleased with the outcome. Tiling is definitely something that I wouldn’t want to do five (or more) days a week.
