ROCK HARD is the first step of a synergistic two-step
polishing and maintenance program for all types of terrazzo and natural
stone. ROCK HARD works to harden the surface of terrazzo, marble and
granite. Then, with the use of DIAMOND GLOSS, an easy-to-maintain, super
high gloss is produced on the surface. Terrazzo (both cementitious and
resinous) will be improved with this process. It is recommended for
polishing hard marble surfaces (such as serpentine) and most types of
granite. It works to form a protective layer at and below the surface.
Continued use of this product will increase the density of the surface.
This will make the surface more resistant to wear and staining.
