Abstract: A method of polishing and coloring concrete surfaces using a dry concrete grinding process which includes locking in dye colors by applying the dye to the cementicious surface mid way during a series of grinding steps using sequentially finer grit, and then applying a sealer after the dye has dried and continuing the grinding process with sequentially finer polishing grits after the sealer has dried and hardened. A second coat of sealer is then applied at the end of the grinding process. In a presently preferred embodiment, the dye is applied after grinding with a grit of substantially 400 grit, the sealer is applied after the dye is dry and grinding is continued up to about 3000 grit after the first coat of sealer dries. Lastly, a second coat of sealer is applied.
