Do not seal the floor prior to the re-grouting. If there is missing grout the sealer will go in between the grout line and the grout will not bond completely to the areas where the sealer is on the edges of the tile where the grout is missing.  The grout will bond for a time but will fail down the road.

Thanks, good info. It has a lot of missing grout. In this case, I think I will go 1st. Refinish to a honed finish @ 220 grit. Soak with a sealer and let the other company do the re-grouting. It is unsanded grout that is being replaced.

Generally we would be doing the grouting (or color sealing) on a restoration such as yours.

When we grind we always grout first.-If the process didn't involve flattening we would generally grout last.

But that depends on certain factors-if the floor was flattened already we will grout first. If we are removing sanded grout and replacing with unsanded we will do that first.

But the questions on your floor are -un sanded or sanded grout.

Why is the grout being replaced,color choice, stained beyond cleaning?

If the joints are a uniform normal size over 1/16 of an inch you could just color seal the joints after refinishing.

You could add a nice revenue boost to the job.(whether un sanded or sanded)

Seems like it is a commercial job where the grout lines are trashed and they have had it with the polished surface upkeep.

If that is the case it may be possible to refinish the floor to a good uniform hone and color seal all the joints to whatever color they like.

I agree with Mike, because if you were grouting that would be different, or if you had a vested interest in making sure that the job of this other company is done as if you had done it.  If they scratch it that is not on you, if rerouting is something they do then they need to take the precautions, but after the grout is done and looks good, they're is no saying what their quality is and you could wind up having to touch up a lot of the floor anyway.

Thanks for follow up, the stone is white carrera, so the grout would be light in color.

Are you flattening? If so then grout first and leave it high so you can flatten it. If the grout has a lot of color in it do it after. It also depende on what you are buffing with. New grout that has color will stain if you are using a honing compound, it is so porous when it is new. I would cover my butt and say "I go first"

I have a large white marble floor to service. Right now it is polished, but we are restoring it to a honed finish. Someone else is re-grouting the floor. What should be done 1st, the re-grouting or the stone restoration and why?
