How To Eliminate Squeeze Up During Tile Installation

Recent Posts

When it comes to the tile installation process, there can be a few hiccups along the way. There’s a large amount of precision and care that goes into the process overall, but especially when it comes to the thin set mortar and grout. While we can likely all agree that the outcome of tiling is something for the books, there may be a few obstacles on our path to finishing the last few chapters.


When installed correctly, eliminating tile squeeze, the result is seamless beauty as seen in this bathroom backsplash featuring our Wooden Grey Fan Marble Mosaic Tile.

One issue in particular? Squeeze up from tiles. This is a common problem even the pros face, and today we’re going to review how to eliminate squeeze up from your tile installation so you can sail smoothly into your next DIY project. 

What is tile squeeze up, anyway? 

When it comes to installing your tile properly, you should always be ready for potential problems with squeeze up between tiles. This is a normal occurrence, albeit a frustrating one. Luckily, solutions exist! Photo via Forbes

'Squeeze up' is an industry phrase that essentially means thin set mortar that creeps up between tile joints. This happens when you apply the thin set mortar, and lay your tiles. The mortar has the opportunity to rise up, and go in between your tile joints. The result is a less-than-seamless experience when it comes time to grout your tiles and finish the job. In the long term, it can lead to gaps in the tile joints as well as cracking. Yikes!

How can you avoid tile squeeze up from happening? 

As mentioned earlier, setting tiles can be a challenging and time-consuming task, but the results can be truly stunning. 

There are a few tips and tricks you can use to minimize the negative effects of tile squeeze up, eliminating it completely. 


Squeeze up issues can be especially troublesome when installing mosaic tiles. Read on to find out how you can achieve a seamless look like this backsplash using our 4 Inch White Carrara Hexagon Honed mosaic tiles.

Consider trowel size. 

You would think if squeeze up is to be eliminated, the use of a smaller trowel would be the best choice. Many times, this trowel of choice is a 5/32” or 3/16” “Vee” notch, but perhaps to the surprise of most of us, this isn’t the ideal size to use to solve the problem of squeeze up.

The “Vee notch” trowel provides about 8 to 12 percent mortar coverage on the back of the tile, but many times, these mosaics are installed in wet areas, which require a minimum mortar coverage of 95 percent. 

That leads us into how to go about finding the right size trowel for the job. 

For most mosaic projects, a ¼” x ¼” x ¼” trowel will provide full coverage with no squeeze up. This size trowel is also relatively easy to control, making it a good choice for beginners. 

Note: When it comes to thicker mosaics, a ¼” x 3/8” x ¼” trowel may be necessary. You will need to judge and make the call.

Overall, the important thing is to choose a trowel that will provide full coverage without requiring too much effort. With the right tools, setting tiles can be an enjoyable and rewarding experience. We promise!

When installing the mosaic or traditional tile, there are a few things to keep in mind for preparation:

  1. It is important to ensure that the substrate is clean and damp before beginning. (Once the substrate is prepared, use the flat side of the trowel to key in the mortar. )

  2. Next, notch the mortar in one direction in a straight line. To apply the mortar to the tile, prime the flat side of the trowel with a small amount of mortar and pull it across the trowel ridges. This will create a smooth, consistent coating of mortar on the tile.

  3. Finally, place the mosaic tile into the thin set mortar at the desired location and beat in with a beating block and mallet or grout float. 

By following these steps, you can be sure that your tile installation will be successful.


Installing backsplash tiles using these tips will help you achieve a seamless appearance as seen here with our Azul Cielo Thassos And Carrara Striped Chevron Mosaic Tile.

Use an oscillating saw or tile scraper. 

Not one to try out a new trowel size? That’s just fine. 

Another, potentially easier option for you, is to rid the thin set mortar creep through scraping away the excess between the joints. This is particularly useful if you plan to complete the tile job over the course of a weekend vs. one day. 

In order to do this concept, you’ll need the following tools:

  1. A sponge 
  2. An oscillating saw or tile scraper
  3. A tile brush

Once you have these items, here’s what you will do: 

  1. Go over the thin set mortar, scraping away the dried squeeze up between the tile joints with the oscillating saw or scraper. 
  2. Take the tile brush and brush away all the dust and grime that is floating around the workspace / tile now. 
  3. Once that’s done, use a wet sponge to rinse away the rest of the dust and make the tile sparkling, ready for grouting!
