Let’s say you’ve got a small section of tile that’s seen better days. Maybe it’s the bathroom backsplash, maybe it’s that mysterious strip behind the kitchen sink. Wherever it is, the grout has gone from “charming patina” to “what even is that color?”
Don’t worry—you don’t need to rip out all your tile or call in a demolition crew. You just need a little know-how, a few tools, and maybe a good playlist. Here’s how to remove and replace old grout in a small area, the right way (a.k.a., the Grout Medic way).
There’s no sugarcoating it—grout removal is messy. Not quite sand-in-your-swimsuit messy, but definitely “why is there dust in my coffee?” levels. Set the mood: lay down drop cloths, tape off nearby surfaces, and open a window if possible.
If you’re working in a bathroom, take the extra step of removing anything that’s within a five-foot radius unless you want gritty toothbrushes and fuzzy soap.
For a small area, you’ve got a few options depending on your comfort level and willingness to break a sweat:
Gently start scraping along the grout line. The goal here is to remove the old grout without cracking your tiles, not dig to the center of the earth.
Once the old grout is removed, vacuum the joints thoroughly. You’d be amazed at how much stubborn debris hides in those cracks. Then, wipe the area with a damp sponge or cloth to clear out any fine dust. Your new grout needs a clean surface to bond properly.
This is the part where you stare at the exposed tile gaps and feel a little bit like you’ve ruined everything. Don’t worry—you’re about to put it all back together.
Grab your fresh grout (unsanded for narrow joints, sanded for wider ones—Grout Medic rule of thumb) and mix it according to the manufacturer’s instructions. You want a consistency like thick peanut butter, not runny pancake batter.
With a rubber float, press the grout into the joints using diagonal strokes. You’re not just filling the lines—you’re convincing the grout that it belongs there.
Once all the joints are filled, wipe off the excess with a damp sponge. Don’t wait too long—if grout dries on the tile surface, it turns into a stubborn haze that’s more annoying than a pop-up ad.
After everything dries (usually 24 to 48 hours), give the tiles one last wipe to remove any remaining haze. Then—very important—seal that grout. Even if it’s a small area, unsealed grout invites stains, moisture, and eventually regret.
A grout sealer protects your hard work and keeps things looking fresh. Plus, it’s oddly satisfying to apply. Kind of like giving your grout a raincoat.
