I have black granite tile, with black grout. I purchased the grout from Home Depot with the blessing of my
'tile guy'. It looked great, much cheaper than solid granite which we will do when a full remodel is possible.
PROBLEM!!! I sealed the grout with super expensive tile sealer from a professional tile store, three times!! Sadly, though, the black grout washes out when I wipe with a washcloth, water only, dawn dish soap, etc. No scrubbing, nothing.
Does Home Depot have bad grout? Did my tile guy do a bad job? what can I do???
