Hey Partners, I was contacted by a contractor who is installing this
high gloss white porcelain (from India). The issue is that after install
but before grouting the tile seems to loose some kind of topical coating
that you can barely tell by looking at it but can feel it when you wipe
across it with a eraser sponge, on the uninstalled tiles its very
smooth, on the installed tiles the sponge drags across the tile but only
in the center area of the tile and not around the perimeter. Also the
tiles seem to stain, an appliance slid across and left a skid mark that
will not clean off, i even tried with some cream cleanser. I have that
porcelain polish from National chemical, would that be a possible fix
maybe after poulticing the stains? IN the picture you can barely make
out a scuff mark that would not clean off with a mild cleanser.

Thank you
