Diamond Grinding is a multi-step buffing process whereby we grind the concrete surface starting with a coarse diamond/metal grit, and moving to a finer grind for a smooth finish. After the grinding process is complete, a special surface treatment is applied and polished into the concrete pores using another multi-step buffing process from coarse to fine diamond/resin polishing tools. This process of polishing and sealing, and buffing the concrete produces a natural polished concrete floor finish that can last with high-traffic for up to 10+ years.
