The new finish is applied as a liquid and covers the grout lines as well. The result is that the grout will be the same color as the tile. Because the grout is so porous, you will have the definition of grout – so it will still have the look of a tile bathroom. Anyone walking into your bathroom will think that you have new tile in your bathroom. A secondary benefit of resurfacing is that the grout will be sealed off. This means that mold and mildew will have a tougher time getting a foothold. The result is that the tile is much easier to keep clean.
