Antique white grout disaster
Hello. My contractor has grouted three times with two different brands of unsanded grout. The issue is that the grout color (Antique White) isn't uniform. It's blotchy ivory and gray. Looks dirty and sort of moldy.
After the first time, I called the manufacturer (TEC) and they said he used too much water. So he re-grouted. It was still blotchy and horrible looking so he switched brands, grouted again. Same effect.
My contractor says that there are color variations (red, yellow, black) in the grout and it will never be uniform. He said to achieve a uniform effect, I would have to use paint! I went to Home Depot and asked if that was correct, and the person said it was not. Rather, they said my contractor either used too much water or did not mix the bag of dry grout well before using a portion of it.
Does anyone know what's going on here? My contractor is coming by tomorrow to seal the grout, and I need to resolve this. The appearance is simply not acceptable.
Thanks so much in advance!
