We can grind the concrete to lighter salt and pepper grind all the way through to a full grind that exposes larger stones buried deeper. There are two ways to seal a concrete floor:

Spray on Sealers

  • Involves scrubbing the concrete with our ride on scrubber and applying a surface sealer to the concrete. An anti-slip additive can be used in the sealer.

The sealed surface is then polished with resin bonded diamonds in various grades until the desired finish is obtained.

The desired finish is highly dependent on the quality of the concrete poured and the curing conditions. Thus, the polished floor may inherit a natural variability in the distribution of the stones. For more information on other types of finishes, kindly send us an inquiry in the Contact Us section.
