NCL ROCK HARD™ Step 1 - Stone Hardener
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.

Features & Benefits
- Increases surface density
- Increases resistance to wear and staining
SURFACE HARDENING: The surface must be dry and free of any coatings, grease or oil. Remove any floor coatings, greases, or soils by using HURRICANE™ Intensive Stone Cleaner.
Mist 4 trigger pulls of ROCK HARD™ Step 1 onto a 9 sq. ft. (1 sq. m) area.
Buff with an AQUA MAGIC™ pad until dry. Repeat this process 1-2 more times until a slight gloss is achieved.
Best results are obtained using the STONE BLAZER™ floor machine with a total weight between 140-180 lb. It may be necessary to repeat this 3-4 times on very porous stone or cementitious terrazzo.
Then mist 3 more trigger pulls of ROCK HARD™ Step 1 and buff with a STEEL FORCE™ pad until the surface is dry.
Repeat process until surface has a moderate gloss at a 60° angle.
The surface is now prepared for using DIAMOND GLOSS™ Step 2 Stone Rejuvenator.
NOTE: If moisture is present, the STEEL FORCE™ pad may leave a dark transfer. Use an AQUA MAGIC™ pad and buff ROCK HARD until dry.
COVERAGE: For ROCK HARD: 25,000 - 30,000 sq. ft. (2,300 – 2,800 sq. m) per gallon.
