The Best Tools and Materials for DIY Tile and Grout Repair

So, you’ve decided to tackle a little DIY tile and grout repair project. First off—bravo! You’re basically one step away from being crowned King or Queen of Home Improvement. But before you dive in, let’s talk about the MVPs of your toolkit. Because nothing kills that DIY spirit faster than realizing you’re missing the one tool that makes all the difference. (Yes, we’re looking at you, missing grout float.)

At Grout Medic, we know tile and grout repair like the back of our trowel. In this article, we’ll cover the best tools and materials you’ll want on hand before you start.

Prep Like a Pro: Cleaning Tools

Before you even think about slapping in new grout, you’ve got to clear the battlefield.

• Grout Saw or Oscillating Tool – For removing old, damaged grout. It’s oddly satisfying, like erasing mistakes from the past.
• Scrub Brush – Not the one you use on dishes, please. Get a stiff-bristled brush to clear out debris.
• Vacuum or Shop Vac – Because grout dust is sneaky and will haunt you if you don’t clean it up.

The Repair Crew: Application Tools

Here’s where the magic happens.

• Grout Float – Think of this as the spatula of the tile world. It spreads grout smoothly into the joints like you’re icing the world’s least delicious cake.
• Tile Spacers – If you’re replacing tiles, spacers keep everything looking sharp and aligned.
• Notched Trowel – For spreading adhesive when re-setting loose tiles. Pro tip: pick the notch size based on tile size.

Materials That Matter

Tools are nothing without the right stuff to use them on.

• Grout – Choose sanded grout for larger joints (wider than 1/8”) and unsanded grout for smaller ones.
• Tile Adhesive (Thinset Mortar) – The glue that keeps your tiles where they belong.
• Sealer – Like a raincoat for your grout, protecting it from stains and water damage.
• Replacement Tile(s) – Because sometimes the old one just can’t be saved. RIP.

Finishing Touches

Don’t forget the grand finale.

• Grout Sponge – For wiping away excess grout and smoothing joints. (Yes, you need a sponge made just for this—it’s worth it.)
• Microfiber Cloths – To polish up tiles after the job’s done. Because no one wants cloudy grout haze ruining their hard work.
