Achieving a professional tile installation isn’t just about good adhesive or sharp cuts, it’s about achieving a flat, level surface across every tile. Lippage (uneven tile edges) doesn’t just ruin the aesthetic, it creates trip hazards, cleaning difficulties, and long-term damage risk.
So, how do you achieve a perfectly level finish, especially with large format porcelain or rectified tiles? The answer: a tile levelling system.
In this guide, we’ll explore how tile levelling clips, wedges, spacers, and pliers work together to produce flawless installations, and why systems like the Tylix Tile Levelling Kit are trusted by professionals across the UK and Ireland.
What is a Tile Levelling System?
A tile levelling system is a toolset designed to eliminate lippage and ensure a flat surface across tiled floors or walls. It usually consists of:
- Tile levelling clips: These go beneath tile edges and set the alignment height.
- Tile levelling wedges: These are inserted into the clips to pull tiles into alignment.
- Tile levelling pliers: Used to tighten the wedges for uniform pressure.
Whether you’re working with 20mm outdoor porcelain tiles, a sleek shower wall, or underfloor heating zones, a tile levelling system kit ensures consistency from edge to edge.
Why Use a Tile Levelling System? – The Benefits for Walls, Floors, and Large Format Tiles
Lippage isn’t just unsightly, it can compromise the integrity of your entire tiling project. A tile levelling system solves this by mechanically aligning tiles during installation, ensuring a flat, professional finish every time. Whether you’re laying porcelain, ceramic, or stone tiles, here’s why tile levelling clips and wedges are a must-have in your toolkit:
- Eliminates Lippage
Tile lippage is when the edge of one tile sits higher or lower than the adjacent tile, creating raised edges or “trippers.” It’s especially visible (and dangerous) with large-format or rectified tiles. Using tile levelling wedges and floor tile levelling clips prevents this by locking adjacent tiles into position during adhesive curing. The result? A flush, even surface with no toe-catchers.
- Suitable for All Tile Types and Sizes
From metro tiles to 20mm porcelain slabs, there’s a tile levelling system for every project. Choose from:
- Tile levelling system 2mm – Ideal for tight grout lines
- Tile levelling system 5mm – For wider grout joints or rustic tiles
- Tile levelling system for 20mm tiles – Built for heavy-duty, outdoor applications
- Works on Floors and Walls
Think levelling is just for floors? Think again. A tile leveling system wall kit is essential when installing heavy or large tiles vertically, helping to reduce slippage and maintain clean grout lines. With tile levelling pliers, you can apply even pressure without damaging the tile face. Many tilers now use levelling systems for walls, splashbacks, and showers as standard practice.
- Saves Time and Reduces Waste
Forget constantly lifting and adjusting tiles. With a tile levelling kit, once you set a tile it stays in place. That means:
- Fewer adhesive readjustments
- Faster installation
- Less tile breakage
- Better consistency across the entire surface
Systems like the Tylix no nonsense tile levelling system kit offer a simple, fast, and cost-effective way to improve your workflow.
- Easy to Use and Reuse
Most tile levelling systems are incredibly beginner-friendly. Just:
- Place the clip under the tile
- Insert the wedge through the clip
- Tighten using tile levelling pliers
- Remove after 24 hours using a rubber mallet or by kicking off the clip
If you’re wondering how to remove tile levelling clips, don’t worry. They’re designed to snap cleanly below the tile surface, and tile levelling wedges are reusable across multiple jobs.
How to Use a Tile Levelling System – Step-by-Step Guide
Whether you’re tiling a bathroom wall or a large-format porcelain floor, using a tile levelling system correctly is key to achieving a flawless result. Here’s a practical breakdown of how to use tile levelling clips and tile levelling wedges on your next job.
Step 1: Prepare the Surface
Before installing your tile levelling tools, make sure the substrate is:
- Clean, dry, and level
- Free from dust or previous flooring
- Primed and prepped where necessary (e.g. using self-levelling compound)
Tip: Even the best tile levelling system can’t compensate for a badly prepped subfloor.
Step 2: Apply Tile Adhesive
Use a notched trowel to apply tile adhesive evenly, following the tile manufacturer’s recommended trowel size. Apply adhesive to one small section at a time to avoid premature drying. Don’t forget to “back butter” large tiles for extra adhesion.
Step 3: Insert the Tile Levelling Clips
Slide your tile levelling clips under the edge of the first tile, around 50mm from each corner.
- Use more clips for larger tiles or porcelain tile levelling system jobs
- For tile leveling system 2mm or 5mm grout joints, choose clips that double as spacers
Step 4: Place the Next Tile
Lay the adjacent tile next to the first one, aligning it tightly against the clips. Press gently to bed it into the adhesive. Repeat this for all tiles in your working section.
For tile levelling systems for walls, apply gentle upward pressure when setting the tile to avoid sagging.
Step 5: Insert the Wedge and Tighten
Push the tile levelling wedge into the clip until snug. Then, using tile levelling pliers, apply even pressure to bring the tiles into alignment.
- Don’t overtighten – just enough to remove lippage
- For tile levelling systems with thicker tiles (e.g. 20mm), make sure you’re using heavy-duty tall clips designed for thicker tiles.
Step 6: Allow to Set
Let the adhesive cure fully, usually 24 hours. Don’t rush this step; moving tiles too early can undo your levelling.
Step 7: Remove the System
Once the adhesive is dry, remove the clips and wedges. Tap gently with a rubber mallet and collect your reusable wedges and store them for the next job
Tools You’ll Need:
- Tile levelling system kit (clips + wedges)
- Tile levelling pliers
- Trowel and adhesive
- Spirit level
- Rubber mallet
Safety Tip:
Always wear gloves and knee pads. If you’re using power tools for cutting or mixing, eye protection is also essential.
Choosing the Right Tile Levelling System – Wedges, Clips & Kit Options Explained
With so many tile levelling systems on the market, choosing the right one can feel overwhelming. Whether you’re a professional tiler tackling high-end projects or a retailer looking to offer the best tile levelling system to your customers, understanding the differences between wedges, clips, caps, and kits is essential.
Wedge-Based Tile Levelling Systems
This is the most widely used system in the UK and Ireland, and for good reason. It’s simple, effective, and works with nearly every tile material, including ceramic, porcelain and 20mm outdoor tiles.
What you’ll need:
- Tile levelling clips – These sit underneath the tiles and create even spacing.
- Tile levelling wedges – These push against the clip to level adjacent tiles.
- Tile levelling pliers – Used to tighten the wedge into the clip without damaging the tile.
Advantages:
- Affordable and easy to use
- Ideal for both walls and floors
- Works well for 1.5mm, 2mm and larger joints
- Popular with pros and DIYers alike
Best for: Everyday tiling, porcelain tile levelling systems, and installers who prefer speed and control.
Spin or Screw-Cap Levelling Systems
Also known as rotary systems, these use a reusable cap that screws down onto a base (clip), applying even pressure to both tiles. These systems are growing in popularity for their reusability and ease of setup.
Features:
- Cap replaces the need for a wedge
- Slower to install but easier to remove
- Often used for both tile levelling system wall and floor installations
Advantages:
- Reusable caps = cost savings over time
- Precise control over pressure
- Great for vertical applications
Drawbacks:
- Higher initial cost
- Slower for large projects
Best for: Detailed wall work, DIYers, and smaller areas where time is less of a factor.
Tile Levelling Kits
Tile levelling kits are a convenient all-in-one solution, especially for new tilers or retailers creating a starter package.
A good tile levelling system kit should include:
- A set quantity of tile levelling clips (usually 100)
- Reusable tile levelling wedges or caps
- A pair of tile levelling pliers
- Instructions and sizing guides
You can find floor tile levelling spacers, tile levelling clips 2mm, and even tile levelling kits for 20mm tiles in ready-to-go boxes.
Retailer Tip: Stock both wedge-based and screw-cap kits to suit different customers. Position near adhesives or tile cutters to boost add-on sales.

Common Mistakes When Using Tile Levelling Systems – And How to Avoid Them
Even the best tile levelling system can only deliver flawless results if used correctly. Whether you’re a seasoned pro or a DIYer using a tile levelling kit for the first time, avoiding these common mistakes can save you from uneven tiles, wasted materials, and costly callbacks.
- Not Preparing the Substrate Properly
A tile levelling system is not a substitute for a level surface. If the substrate is uneven, even the most advanced tile levelling clips and wedges won’t deliver a flat finish. Use a self-levelling compound to ensure the surface is smooth, dry, and clean. For floor tile levelling clips to work correctly, the floor needs to be as flat as possible before you begin.
- Using the Wrong Clip Size
Using 1mm clips when a 3mm joint is specified can throw off your entire layout and affect grout bonding. Check whether you need a tile levelling system 1.5mm, 2mm, 5mm, or a tile levelling system for 20mm tiles. Always choose the correct clip width and height to match your tile thickness and desired grout line.
- Over-Tightening the Wedges or Caps
Applying too much pressure with your tile levelling pliers or by hand can lift tiles, break clips prematurely, or squeeze adhesive out from under the tile, reducing bond strength. Practice applying firm but gentle pressure. The goal is to align the tile faces — not force them together.
- Leaving Clips in Too Long
Leaving the system in place for too long can make removal harder or even damage the tiles when trying to remove the clips. Always follow adhesive manufacturer guidance. Typically, tile levelling clips should be removed 24 hours after installation, once the adhesive is fully cured.
- Not Using Enough Clips
To cut costs, some installers space clips too far apart, especially on large format or heavy tiles. This allows corners or edges to shift during setting. Use at least two clips per side for tiles larger than 600mm. For best results, place clips 50–75mm from each end of the tile and a third one in the middle if needed.
Bonus Tip: Don’t Forget the Corners
A mistake even experienced tilers make is failing to properly level the four corners where tiles meet. This can lead to subtle height differences that become obvious when grouting.
