Yup yup yup, looks like it has been waxed. Our wal mart waxed their entry tile a couple years ago. Knowing the mess they were in for I took these pictures over about a 3 month period. The first picture is about a month after waxing, the second one a month later, and the last one a month after that.
They have since tried to strip it all off LOL and even now two years later you can still see spots of wax where they have not been able to get it all off. The grout looks horrible now.
