The harsh aggregate material present in sanded grout can damage delicate materials such as granite, marble, limestone, and other soft stones. If you don’t manage to coat your entire work area in your epoxy-based unsanded grout before it cures, it’s going to become totally stiff and unworkable – you won’t be able to spread it at all. Sanded grouts, such as MAPEI's Keracolor S grout, are generally recommended for grout joints 1/8" (3 mm) and larger. MAPEI Flexcolor CQ is a professional-grade, ready-to-use specialty grout for precision commercial and residential installations with porcelain, ceramic and natural-stone tiles. Still, if you’re working on highly-polished tiles that have a joint of more than ⅛ of an inch, epoxy unsanded grout is going to be the best choice.Still, it seems unusual to us that the subcontractor is charging you directly, rather than indirectly through the contractor. Usually, most contractors use an epoxy-based unsanded grout in these situations – not traditional sanded or unsanded grout.

When grouting installations of polished stone tile, it is recommended to build a mockup (sample board) or, at the very least, test MAPEI Flexcolor CQ in an inconspicuous area before grouting.

The aggregate “sand” material used to create it can be quite bulky, and preclude you from being able to squeeze it into small tile joints, making it unsuitable for precision work.
