5 Common Mistakes to Avoid When Using Floor Spacers


Are you tired of unsightly grout lines and uneven gaps in your tiling projects? A small tool makes a big difference in tile installation – the floor tile spacer.

Yet, many professional and DIY tilers often need to correct their mistakes when using these vital tools. To get that professional finish, it’s essential to understand how to use floor tiles with spacers properly.

In this blog post, we’ll discuss five common mistakes and give you expert tips to avoid them, ensuring a flawless finish for your floor tiling projects. These tips will significantly enhance your tiling expertise, whether you’re laying ceramic tiles or clay ones. Let’s turn your tile laying into wins.

What is a Floor Spacer or Tile Spacer?

A floor spacer, often referred to as a tile spacer, is a small yet crucial tool in the tile installation process. Usually made of plastic, these little objects come in various shapes, including cross-shaped spacers designed to create precise gaps between tiles. Tile spacers are mainly used to guarantee an even gap or grout lines between each tile, providing consistency throughout the entire tiling project.

Whether laying floor tiles or installing wall tiles, using tile spacers can differentiate between a professional-looking result and a flawed outcome. Remember, laying tiles is a precision job, and every millimeter counts. These simple tools ensure your tiles don’t slide around during the adhesive drying, leaving you with a well-aligned, beautifully finished surface.

But why is this tiny piece of plastic so important?

It all comes down to the structural integrity of your tiling project. Correct spacing isn’t just about aesthetics; it also affects the durability and longevity of your tiles. Irregular spacing can lead to tiles loosening over time or even cracking under pressure. Therefore, the seemingly simple task of correctly placing a tile spacer can significantly enhance the overall success of your project.

5 Common Mistakes When Using Floor Spacers

1. Misalignment and Uneven Spacing

When laying floor tiles or wall tiles, achieving a professional finish depends heavily on the evenness of your tile placement. Misaligned tiles and uneven grout lines can occur when tile spacers aren’t used. They can cause a lack of uniformity, undermining your tiling project’s aesthetic appeal and structural integrity.

Why does this happen?

It’s often due to rushing the tile installation process, needing to press the tiles into the adhesive adequately, or placing the spacers inconsistently.

The consequences?

You may notice gaps of varying widths between tiles, leading to uneven grout lines that mar the beauty of your room. Moreover, these irregular gaps can create weak spots, compromising the durability of your tile installation.

So, how can you avoid this pitfall?

Start by planning your project carefully. Use a chalk line or laser level to mark your starting point and ensure your first tile is aligned correctly. From there, it becomes much easier to maintain proper alignment for the following tiles.

When you lay each tile, place it firmly into the adhesive, then position the tile spacers. Depending on your project and personal preference, these could be cross-shaped spacers or other shapes. Remember, they should be placed at each tile corner to maintain an even gap.

Lastly, avoid the temptation to rush. Proper tile installation requires patience and precision. Measuring and aligning your tiles will pay off in the long run, ensuring a flawless and durable result.

2. Incorrect Spacer Size Selection

The next mistake that tile installers usually make is the incorrect selection of spacer size.

Yes, that’s right! Just as there are different sizes of floor tiles, there are also different sizes of tile spacers, and picking the right size is crucial for your project’s success.

Firstly, what is the relationship between tile size and spacer size?

A general rule of thumb is that larger tiles require larger spacers. That’s because more oversized tiles have more weight that could cause shifting during installation, and larger spacers help maintain consistent spacing and prevent sliding.

Choosing the incorrect size of the spacer can lead to irregular gaps and grout lines, affecting the visual appeal of your project. Moreover, inappropriate grout width can compromise the structural integrity of your tiles, causing them to loosen or crack over time.

How can you ensure you pick the right size spacer for your project?

The size of the spacer you select depends on the size of your tile, the type of tile (such as ceramic tile or clay tile), and the location of your project. For example, you might need spacers as small as 1/16 inch for small wall tiles, while larger floor tiles require up to 1/2 inch.

However, personal preference and the desired look also play a part. If you prefer more comprehensive grout lines, you might opt for larger spacers, even with smaller tiles. Also, consider the advice of the tile and adhesive manufacturer, as they often provide guidelines for the best spacer size to use with their products.

By choosing the right spacer size for your tiling project, you ensure an even, professional finish that enhances the room’s aesthetic while maintaining the durability of the tiles.

3. Not Removing Floor Spacers Before Grouting

Next on our list of common mistakes in tile installation is leaving tile spacers in for too long. Many tiling novices wonder, “Should I remove tile spacers before grouting?”

The answer is a resounding yes!

However, only some follow this crucial advice.

Tile spacers are not meant to be permanent fixtures. Spacers can get stuck in the adhesive when left in too long. This can create significant problems when it comes time to grout. You might be wrestling with a pair of needle-nose pliers trying to remove the stuck spacers, which can potentially damage your tiles and disrupt the overall layout.

Furthermore, if spacers are not removed before grouting, they can interfere with the grout’s ability to bond, resulting in a weaker tile installation.

So, how can you avoid this common mistake?

The key is to remember that tile spacers are temporary aids meant to be removed once the adhesive is set but before grouting begins. In most cases, this would be the next day, but it’s always wise to follow the manufacturer’s guidelines regarding adhesive setting times.

When removing the spacers, do so gently to avoid displacing the tiles. Using a tool like a needle nose pliers can make this task more accessible and precise, and remove the clip with a rubber mallet.

4. Misplacement of Most Spacers

Another common pitfall that DIYers and even some professionals encounter while installing tiles revolves around the incorrect placement of cross shape spacers. This issue can significantly affect the outcome of your tiling project, particularly when it comes to the task of removing the cross spacers.

Often, individuals lay the spacers flat at the corner where four tiles join.

Although it may seem like the logical spot, this method can complicate the removal process, potentially causing the spacer to get stuck and making it harder to pull out without disturbing the tiles or damaging the adhesive, and with the tile spacer laying flat underneath the tiles you will not also be able to get grout underneath the corner most of the time.

What is the right way to place your floor or wall tile spacers?

The best practice is to position the tile spacer upright between two tiles. By placing the spacer in this manner, you maintain the necessary gap for the grout lines and make the removal process more straightforward and less risky. When it’s time to remove the spacers, whether using needle nose pliers or screwdrivers, you’ll find it much easier to pull out upright spacers without disturbing the surrounding tiles or adhesive.

Should you choose or find it necessary to place your spacers at the four-tile intersection, you can still ensure a smooth removal process using a long-needle screwdriver.

This allows you to gently dislodge and extract the spacer without causing damage to the tiles or disrupting the adhesive.

However, another solution is available to those who prefer placing spacers at tile intersections – shanked tile cross spacers. Unlike their cross-shaped counterparts, Shanked cross spacers feature a handy ‘handle’ or ‘shank’ that protrudes above the tile surface. This design allows easy removal, as you need to pull on the shank to extract the spacer.

5. Using Rubber Tile Spacers for Tiling

One more typical error creeping into the tile installation process revolves around the choice of tile spacer material. Some might find rubber spacers appealing due to their perceived flexibility, but we’d advise against them.

But why is this?

Though seemingly user-friendly, rubber tile spacers tend to be inconsistent in shape and dimensions. This lack of uniformity can lead to uneven grout lines and spacing in your tiling project, disrupting the pattern you aim to achieve.

Furthermore, rubber spacers can create additional complications if you embark on a wall-tiling project. Due to their softness, they’re prone to compress under the weight of the tiles, which results in irregular tile joints and less filling of gaps during grouting, jeopardizing both the aesthetics and structural integrity of your tiling installation.

So, what’s the alternative to rubber tile spacers?

Our strong recommendation is to opt for tile spacers made from high-grade Polypropylene (PP) material. These rigid plastic spacers hold their shape under the pressure of tiles, providing consistent, even gaps crucial for precise grout lines.

Whether laying walls or installing floor tiles with a spacer, these sturdy spacers can stand up to the task, ensuring a high-quality and professional-looking result.


Avoiding common mistakes in your tiling project—installing floor tiles with a spacer or laying wall tiles—is critical to achieving a professional finish.

Attention to these finer details will make a big difference, turning your tiling project from good to excellent.

With the proper knowledge, tools, and methods, you can create a lasting, appealing surface that enhances the beauty and value of your space.
