Any one use this product,you mix it with cement based grout and its claimed to make grout stain free.
I've used it a few times and its real easy to work with,
not sure why they have different units for sanded and unsanded.liguid all seems to be the same to me??
Its a bit pricey but what the hey,if i never have to use epoxy again it id be fine with me,yet ive never tried the STAR-QUARTZ URETHANE stuff either, any thoughts??ISLAND TILE CRAFT.

Sorry, don't know anything about that product. Its not available up here.
