The Ashford Formula does not cover up blemishes and flaws seen on the surface of the concrete. When it penetrates and reacts, it works inorganically to densify the floor, eliminate dust, and make the floor harder. All of these properties are brought about through chemical reactions. That is, the Ashford Formula leaves no film, coating or membrane on the surface of the floor. Because nothing is covered up, the floor will look much as it did before the Ashford Formula was applied.
