My marble counter top is made of tiles. We bought the house and the previous owners installed them. my problem is that the grouts between are chipped and stained. how can i repair them to look new again?
you need to remove the old grout on the surface and re apply new grout to fix the problem, you can even get grout that is tinted to the colour that you like .
Tile stores sell a tool to remove old grout. Only a few dollars. You can remove and regrout, not a difficult job. You can buy stain proof grout that is pre-mixed. Follow instructions on the label. You will love the results.
