As another option, Rock Solid Designs suggests concrete overlays. Concrete overlays are genuinely used on pre-existing surfaces including old concrete and tile floors. The overlay is a material made up of cement, acrylics/polymers and small aggregates. The material colors that are standard are white and gray. However, you may also add many color pigments during the application to create integral color overlays. Likewise, the overlay material can be surface stained like ordinary concrete slabs. This option has an infinite color scheme.
