How to Replace Grout – and Keep It Looking New

  • Transcript

    LESLIE: Joyce in Missouri is on the line with a grout question. What can we do for you?

    JOYCE: Hi. I have ceramic bathroom tile that I have had down for a few years. And I have – the grout is a charcoal color with a black-and-green tile. And the charcoal has dulled over the years and looking almost chalky. What can I do? Do I have to pull all that grout out and regrout it? Do I need to paint it or what can I do to give it new look of life?

    TOM: Well, the grout is pretty easy to replace – on walls and around tubs, at least.  Replacing grout between flooring tiles is more labor-intensive. For your situation, there is a special tool called a grout saw that you can use to carve out the grout and then put new grout over sort of where the old grout was. You know, you don’t have to get it all out but you’ve got to go down at least an 1/8-inch or so. And so, if your real concern is the grout and the condition of the grout, I think that’s the easiest way to deal with that.

    JOYCE: OK. So that’d be – the best way to make it look fresh and new again is just take the top layer off at least an 1/8-inch and just regrout it?

    TOM: Yeah. Make it look fresh and new by putting in fresh and new grout.

    LESLIE: Yeah. And then make sure you seal it.

    TOM: Right. Yeah, that’s key. You want to seal the grout to keep it clean.

    LESLIE: Otherwise, it’s not going to look fresh and new for so long.

    JOYCE: Seal it after I put new grout in and let it dry? Then seal it and then we’re good to go?

    TOM: Right, exactly.

    JOYCE: OK. Thank you.
