I have a tile shower that is functional, but has some undesirable things about it:
- The tile is white but much of the grout has become stained dark
- There are areas where the grout has started eroding
The shower could use a remodel but it might be 5 years before I can make that happen. My question is this: If I go over all the grout with a grout pen, how long can I expect it to last? Will it prevent eroding grout from eroding further (at least for a year or two)? What are the downsides to using grout pen?
Thanks for any advice!
