Well either someone installed the vct upside down or you guys scrubbed the hell out of the vct resulting in dust from the tile suface. Is this new vct flooring or old?
************************************Its new VCT. I have had the same result on more then one job. Today I got down to really look at it and it looks like dirt in "pors" of the tile. Someone told me to use a high speeed buffer with a white pad and water. He think I scrubbed the dirt out but also the surface of the tile. Thanks for the help
************************************VCT is not expensive unless this is non-stocked special order tiles..you can buy vct at 39 cents a square ft and install new vct. Hope you did not use too much glue on the floor otherwise your removal of the bad vct is going to be very labor intensive. Even with a powered floor scrapper.
It sounds as though you are installing vct upside down, you can easily tell one side of vct is glossy and the other is not.....
