This tile job was bad one, it wall all black and even under the beds and couches were black 1600 sq ft of nasty tile. here are some pic.
customer send pic of job she was blow away.
I used tile master and then scrub with CRB then used the tile spinner.
Looks great, not sure if it qualifies as the "tile job from hell" though...looks pretty standard. Are friend in Las Vegas probably wouldn't have even used chemicals just cranked his machine up to 5000 degrees and 1.2 million PSI and blasted that b1tch clean...
one more thing, this is the first job that it was black in clos and under all the furniture. could not find the original color no were. it was black all the way to the baseboard. even under china hutch. this is what I call mop damage. the owner used a commercial mop and bucket to clean the floors. I told him to throw it away. show him how to mop the floor the right way. done many black grout looking jobs this one would not come clean. thank god for the CRB with the black brushes and aloha Dave devil brushes. some joints had to get on my hands and knee with a ss wire brush and acid.
