Generator Superstore – Stratham, New Hampshire – This slab is located in a strip mall that was constructed approximately 30 yrs ago. The customer requested a black diamond graphic, centered in the front (retail) portion of the unit. Measurements were taken and temporary protection was set up. Stain and densifier were applied, and the slab was polished to an 800 grit finish. Months later, the floor was restored to its original polished condition by washing and burnishing it in a couple of hours.
