This job from 2013 still looks like it was done recently. We began this dyed and polish job by grinding the concrete to a Class B: Salt & Pepper exposure and applying a black dye. It was then polished to a Level 3: Semi-Polished finish. The floor was hardened using Retroplate 99 and sealed with Retroguard. This durable polished concrete floor has withstood many years of use and will continue to do so for many more.
