How much grout do I need to remove to Regrout?

The tile grout should be scraped out with a Grout Getter about 1/8” to 3/16′ below the top edge of the tile. This will allow enough room for the new grout to substantially fill in the grout joints. The old remaining grout in the joints will act as a good roughed-up bonding surface for the new grout to adhere to.

Do you have to remove all the grout when Regrouting?

You don’t need to remove all the grout, or even most of it, but removing the dirty grout on the surface gives the new grout something to which to bond. Removing much of the grout isn’t necessary; just get it down enough from the surface to allow new grout to bond. Vacuum up any loose dust and particles.

What to do if you leave grout on too long?
