How to Grout a Tile Backsplash in 8 Easy Steps

So, you’ve decided to tile the backsplash in your kitchen. Great! When done correctly, this project can really transform the space and make a bold statement. If done poorly, however, the end result can be a disappointment. 

What really brings a tile job all together is the grout. Sharp, clean grout lines make the backsplash a feast for the eyes. A poorly grouted backsplash, on the other hand, can look dingy and amateurish. 

If you’re the DIY type and want to give your kitchen a fresh, exciting new look and feel, the following step-by-step guide will help you grout the backsplash like a pro. 

Step 1: Protect All Surfaces

Before any work begins, protect all the countertops with plastic sheeting. Make sure to secure the edges with painter’s tape to ensure the plastic stays in place throughout the project. 

Step 2: Mix the Grout

Use a small bucket to mix the grout. Only mix a small amount at a time so it doesn’t have a chance to harden on you before you can use it all. Grout should be the consistency of peanut butter. 

Step 3: Begin Spreading the Grout

Hold the grout float at a 45-degree angle and begin spreading the grout in an upward direction. Spread the grout over the tiles making sure it fills each joint completely. 

Step 4: Wait

Set a timer for 15 minutes and allow the grout to dry. 

Step 5: Rinse

Get a second bucket and fill it with warm water. Using a sponge, wipe the excess grout from the tiles. 

Step 6: Wait

Allow the grout to completely dry for the next several hours. When dry, use a clean cloth to remove any leftover grout haze from the tiles. 

Step 7: Seal

After allowing the grout to cure for at least 24 hours, use a clean cloth and sealant to seal the dried grout. This step may not be necessary if you purchased a grout that already contains a polymer sealant.

Allow the sealant to cure another 24 hours before using the area.  

Step 8: Caulk the Backsplash

Apply a bead of caulk around the backsplash. Be sure to caulk under windows, around corners, along the countertops, and along any exposed edges of the backsplash where it meets another surface. 

Once the caulk is dry, your kitchen backsplash is ready for action. Take a step back and enjoy all your handiwork!

Many homeowners think that tiling a kitchen backsplash is hard work. The reality is, tiling the area is the easy part. Grouting it correctly takes skill. Luckily, if you follow the step-by-step guide above, you’ll be able to grout that tile backsplash like a pro.
