This marble polishing and grout cleaning and color sealing job was done in Brick NJ. Notice the huge contrast in these before and after pics. Besides the obvious difference that the marble is polished and shines as opposed to the dull low hone finish of beforehand, notice the grout color. Cleaning the grout and sealing it as well as changing its color from white to dark brown makes the grout blend in to give an even greater beauty to the marble. Many glamorous halls and buildings have highly polished marble floors. Many times it is terrazzo which has no grout joints separating it. This has a sleek appearance that spreads like glass. Even with grout lines if they are thin and the grout color matches to blend properly it can have a similiar effect. Color sealing grout can achieve this by customizing the grout color desired without the need to remove or change grout. Furthermore this will enable easier maintenance by rendering the grout stain proof.
