Then the contractor grids the concrete again with finer diamonds resulting in a smoother surface. But that depends on your end goal regarding the finish and desired durability, so a second grinding may not be necessary.

After grinding, the surface is cleaned thoroughly. During this step, a staining colour can be added if you want, and you can choose between different earth tones and appealing concrete dyes.

The last step involves resealing the concrete floor using a high-performance sealer for durability. Depending on your floor goals, the concrete installation company can advise you on the most suitable grind and seal finish for your project.
