Our grout color staining clients all want their grout to look better. If you try it yourself, your grout could look worse. This is not simply because our trained technicians are better at applying the stain itself. There is also certain preparation for a tile grout color stain project that must be performed. Grout must be healthy and clean for the best color stain result. The Grout Medic will ensure that your grout is in its best possible form before a brush even touches your grout lines.
