FAQ: How To Regrout Shower Wall Tile?

Can I put new grout over old grout?

The short answer is, “no.” You cannot put new grout over old grout. With regard to filling in holes and cracks on the surfaces in our homes, we might compare grout repair to drywall repair.

Do I have to remove all old grout before 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. After all, grout primarily is just cement. Removing much of the grout isn’t necessary; just get it down enough from the surface to allow new grout to bond.

Can you touch up grout?

If there are small areas where the grout is cracked or crumbling, you can repair the areas without scraping out every grout line and starting over. If your grout has mildew stains, clean with a mildew-killing product before applying liquid grout touchup coloring.

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.

Can I use silicone instead of grout?

Grout is a hardwearing emulsion but should only be used between joints of the same plane. This means any corners or bends that your tiles and fittings encounter should be handled with silicone instead. This is because grout is not flexible enough to withstand any structural movement.

Can I use caulk instead of grout in shower?

Caulk is used to waterproof joints for space like bath tubs, showers, windows etc. Caulk is strong enough to adhere to tile surfaces without crevices. Caulk may shrink or dry out over time, which is why it shouldn’t be used in large installations or as a replacement for grout.
