Fred:  In my experience, sanded grout will not “hold” the enhancer over time.  It will become modeled again and have color variations.  Initially, it will appear to solve the problem, but ColorSealing will provide a longer lasting solution in this case.  Again, this is based on my experience with this.  Feel free to call me with questions.  Thanks…Nino 440-521-6565

Baird;

 

All the options you mentioned will work and my best advise would be to test them first. I agree the color enhancer would be the easier solution.  Just make sure the grout is cleaned and dry first.

Hi Everyone,
I have a client who recently had about 3000 sf of tile installed in his house. Apparently they think that the grout is not dark enough for their tastes (hydroment flash walnut) .  I inspected the floor and removed any white efflourescent residue.  I then color enhanced a small strip of grout with some impregnating sealer that they had around (I did not have a a proper color enhancer on hand) and unfortunately it dried without darkening the grout (although looked great when wet).  My plan was to go back and try a solvent based color enhancer ( I have an old can of MB-? color enhancer). But, was wondering if anyone has a good line on a decent color enhancing product?  Would some dark concrete dye help if mixed with the enhancer?  It would be great to find something that doesn't dry out too quickly or creates a more or less permanent color enhancement/darkening.  Have thought about color sealing with grout perfect color seal, but am concerned about the color seal migrating beyon
 d the
grout line and wear and chipping down the line. It would seem to me that color enhancer would be easier to apply and to touch up later.
Thanks so much.
