As far as the appearance of the stained concrete goes, we affirm what the L.M. Scofield Company, the maker of Lithochrome Chemstain, prints on its Tech Data Bulletin A-414.02 in section 2:

Limitations: Lithochrome Chemstain cannot be used to hide surface blemishes or to cover construction errors. The variegated colors produced are unique to each concrete surface and depend on the chemical composition, mix design, porosity, age, texture, and color of the concrete substrate. The surface appearance will also be influenced by the Chemstain color, preparation methods and application procedures...Mottling and wide variations in color and intensity will occur. The color obtained and the depth of penetration is not predictable, and it is not possible to successfully stain some concrete surfaces. If contaminants remain on the surface, the penetration of the chemical stain may be blocked....
