Grout colorseal can be a great way to refresh your tired-looking tile. Over time, grout can become discolored or stained, making your entire tiled surface look dull. Grout colorseal acts as a colorant and sealant, allowing you to restore the original grout color or even give it a whole new look. This can revitalize the entire look of your bathroom or kitchen for a fraction of the cost of replacing the grout or tiles altogether.
