These 50+ year old bathtub tiles are set very close together, less than 1/8".
There are numerous little "chips" that don't seen to go deep to the backing board, but maybe they have little cracks that do.
I'd rather not scrape out the grout down deep enough to re-grout in all these places.
I'd like to re-whiten the grout and then wipe on a sealer that hopefully also has enough body to fill these little divots.
Is there a product that will do that?
