Filling Gaps Between the Tile and Wall: 4 Efficient Methods to Follow

Suppose that you’ve finally attached tiles to your wall after much effort. But now the gaps between them are sticking out like a sore thumb! How heart-breaking is that?

How exactly do you fix this and fill gap between tile and wall?  

Firstly, caulking the gaps is a very useful method you can apply. If not, you can use a baseboard to close the gap! Filling the gap with cement is another available method. Finally, building a ‘fake’ wall to cover the gap is also a smart move!

A bit confused on how you can do all these? We got you covered. Read this piece for an in-depth discussion about these methods!

How Do You Fill the Gap between Tile and Wall?

Grouting is not usually a recommended method to fill the gaps. But you can easily use other easy methods. We have narrowed down the 4 most useful ones below for your convenience. They are as follows-

Method 1 of 4: Caulking the Gap

We would personally recommend you to use acrylic or latex caulks for filling gaps. Since they have elastic properties. So they won’t crack due to movements happening over the wall. 

Silicone caulking has a tendency to be peel off later on, so it’s best not to use them. Then again, does your area often come in contact with water? In that case, silicone caulking would be ideal.

Now before caulking gaps, there are some steps to be followed. Which are-

Cleaning the Area

Scrape off all the dirt that has accumulated inside the gaps. Vacuum out everything and take a bowl of rubbing alcohol. Then, take a sponge and start scrubbing the area. Let it dry afterward.

Applying the Caulk

For the next step, take your caulking gun and load the caulk tube inside it carefully. Cut the end of the nozzle using scissors. Pull the trigger of the caulking gun to start applying it. 

Carefully seal the gaps between your tile and wall. It is recommended that you hold the gun at 45 degrees while applying the caulk. Once you’re done, smoothen the caulk using a caulking tool.

You know, caulks are actually used for many purposes in this way. Just like filling gaps like this, they are used to caulk baseboards to the tile floors too!

Observing the Area

For the final step, let the caulk dry after you’re done sealing the gap. Wait for 24 hours to let it completely dry. Afterward, search for any uneven places. Because sometimes, there might be holes inside your caulks by termites after caulking.

If that’s the case, apply the caulk again in those specific damaged areas. Then, wait for another 24 hours. 

Method 2 of 4: Using a Baseboard

For filling gaps with a size of around ¼”, baseboards are perfect! So, all you need to do is put the baseboard between the gaps and simply grout them. And voila! It’s done!

Apart from wooden baseboards, there are multiple things you can use as alternatives too:

  • Vinyl cove base
  • Toe base
  • Shoe molding
  • Quarter Round Piece
  • A bevel-edged tile (Preferably of the size 3×12) 

We’d like to give you an additional tip. That is, are you using baseboards to fill the gap between hard surfaces? By hard surfaces, we mean filling the gap between the floor tile and wall

If that’s the case, install a quarter round or shoe molding along with your baseboard. Because for hard surfaces, one layer of baseboard is not sufficient. There might be cracks between the surfaces later on. 

So you see baseboards are a wonderful solution to this problem! In fact, many people often make a transition from wall tile to baseboards for their multiple uses too.

Method 3 of 4: Filling with Cement & Sand Mixture

Filling gaps using cement and sand is an option used by many! For this, collect a portion of your local sand. Then, take 15 cups of sand and mix it with 5 cups of cement. You can adjust the amount in a 3:1 ratio

After that, you need to mix this mixture with a pack of Styrene Butadiene (SBR). This is a synthetic rubber emulsion that will improve the quality of your sand and cement mixture. 

Thoroughly mix the mixture. Then, create a mold of your desired shape. Apply it inside the wall and tile. You can take the help of a small trowel and brush to get the desired shape. Just let it set and you’re done!

If you don’t have SBR, you can mix lime mortar with your cement mixture too!

Method 4 of 4: Building a ‘Fake Wall’ 

Sometimes you’ll see that there are significant gaps. This is because your wall was exposed to moisture. Then, your wall and tile won’t even have equal gaps at varied distances. So, how to fill the large gap between your wall and tile then?

You see, for this kind of problem, there is a smart trick that you can use! Which is, making a ‘fake’ wall. Don’t get what we mean? Hold on, we’re explaining.

You can use a tile-setter and cement to construct an extra layer of ‘wall’ for filling the gap. Then, enclose the gap between your original wall and tile. Flush the ‘fake’ wall to their surface and you’re done!


Question: Can you grout between wall and tile?
Answer: It is not recommended to grout between wall and tile. This is because grout is not flexible. And it cannot withstand the pressure of walls. This will lead to the cracking of walls. So caulking is recommended instead.

Question: How do you transition from tile to drywall?
Answer: The easiest method of transition from tile to drywall involves using the ‘Schluter Profile’. The method uses metal bars to fit over the edges of tiles. 

Question: How big of a gap can I fill using a bead of caulk?
Answer: A single bead of caulk can fill a gap of ¼ inch. If the gap is greater than that, then simply apply to the deeper areas. Then, wait for your caulk to dry. Next, apply another layer of caulk. Keep doing until all the space between the wall and tile is covered.

Final Words

These are the 4 methods using which you can fill gap between tile and wall

Simply remember that caulking is a common solution to this problem. Otherwise, using cement as a sealant can also serve the purpose. Using baseboards or another layer of the wall are other options you can go for!

Good luck!
