How to achieve perfectly level tiling?

Are you planning to tile a bathroom, kitchen, toilet, or terrace soon? For a durable and clean result, a proper system and the right tiling tools are essential. At Nivello, you’ll find everything you need to install every tile neatly and evenly. In this article, you’ll discover why a leveling system is so important, which accessories you need, and how to tile step by step like a professional.

Why a leveling system is essential when tiling

A tile leveling system is the solution to quickly and easily achieve a level result when tiling floors and walls. With this system, you prevent height differences between one tile and another. The result? No protruding edges or sunken tiles, but a clean and professionally installed floor or wall.

In addition, you save time, because the tiles are immediately placed at the correct level. Especially with large-format tiles, a leveling system is indispensable: the larger the tile, the faster small irregularities become visible.

Tools needed for perfectly level tiling

To tile properly, you need a combination of basic tools and smart accessories:

• Leveling system: prevents height differences between tiles
• Notched adhesive trowel: determines the correct amount of adhesive under the tile
• Tile adhesive: ensures a strong and lasting bond
• Rubber mallet: gently tap tiles into level
• Tile cutter or grinder: for clean edges and cuts
• Sponge and grout float: to finish joints evenly and keep tiles clean

Step-by-step guide to level tiling

1. Preparing the substrate

Proper preparation of the substrate is crucial for perfectly level tiling. Always check whether the floor or wall is clean, dry, and completely level; remove old adhesive residues, dust, and loose particles that can interfere with adhesion. For irregularities greater than 2 to 3 millimeters per 2 meters, leveling is necessary to prevent height differences between tiles. Moisture content also plays a role: substrates that are too wet can lead to loose adhesive or cracked grout. Depending on the type of substrate, choose the right primer. An absorbent floor or wall requires a primer that reduces absorption, while non-absorbent surfaces such as concrete or existing tiles require a bonding primer for optimal adhesion. By carrying out this basic step carefully, you lay the foundation for a clean end result.

2. Determining the layout pattern and grout width

Determining the layout pattern and grout width is an important step that is often underestimated when tiling. A well-thought-out layout plan prevents crooked edges and small cut pieces that make the final result look messy. Always start by marking a reference line with a spirit level or laser and dry-lay a number of tiles to check the pattern and cutting lines. Depending on the space and tile size, you can choose a classic straight layout, a brick bond pattern, or a creative pattern such as herringbone. Grout width not only affects the appearance but also the durability of your tilework. Narrow joints of 2 to 3 mm are ideal for large rectified tiles, while rustic or natural stone tiles often require wider joints of 4 to 6 mm. Always use high-quality tile spacers to maintain consistent width and keep the lines straight.

3. Mixing and applying tile adhesive

Properly mixing and applying tile adhesive is essential for a durable and level result when installing tiles. Always use a clean bucket and a mixer to prepare the adhesive with water according to the specified mixing ratio. Too much or too little water leads to poor adhesion or tiles sinking. Let the adhesive rest briefly after mixing and stir again for a homogeneous mixture. Then apply the adhesive to the substrate using a notched trowel. Choose the correct notch size based on the size and thickness of the tile: the larger the tile, the coarser the trowel must be to ensure sufficient adhesive coverage. Always spread the adhesive in one direction so that no air bubbles remain under the tile. Regularly check that you have at least 80–90% coverage, and for large-format tiles or outdoor applications even 100%.

4. Installing tiles with a leveling system

Installing tiles with a leveling system is the key to a clean and level end result. Always start at your reference line and carefully place the first tile in position. Then slide spacer clips under the edges before placing the next tile, so you immediately maintain the correct height and joint spacing. Insert a wedge into the clip and use the special leveling pliers to tighten it evenly. This prevents tiles from sinking or creating unwanted lippage. Work row by row and keep checking with a spirit level or laser whether the tiles are straight and level. Especially with large-format tiles, a leveling system is indispensable, as even small height differences quickly become visible. Also make sure to use enough clips (usually two per side) for an optimal result.

5. Letting it dry and removing the system

After the tile adhesive has cured, it is time to safely remove the leveling system. Do this by tapping the wedges sideways with a rubber mallet or your foot, never upwards. This prevents damage or shifting of the tiles. The clips will automatically break off under the tile, leaving no visible residue in the joints. After removal, always check whether all clips are completely gone and whether the joints are clean enough for grouting later. This is especially important for large-format tiles or narrow joints, as leftover clip residues can interfere with the grout. Also ensure that you only start grouting once the adhesive has fully cured according to the manufacturer’s drying time.

6. Grouting and finishing

Grouting and finishing is the final, but equally important step in tiling. Once the adhesive has fully cured, fill the joints with grout mortar, applying it diagonally across the tiles using a grout float. Work in small sections and press the mortar firmly into the joints to avoid voids. After the grout begins to set, remove excess material with a slightly damp sponge; always work diagonally to avoid pulling grout out of the joints. Rinse your sponge regularly and refresh the water to keep the tiles clean and prevent haze. For a clean finish, seal all edges, expansion joints, and connections with silicone sealant. This prevents cracking and ensures a watertight seal, ideal for bathrooms and kitchens. By carefully grouting and finishing, you not only extend the lifespan of your tilework but also achieve the best final result.

Common mistakes when leveling tiles

Even experienced DIYers sometimes make mistakes that can significantly affect the final result of their tiling work.

A common issue is incorrect mixing of adhesive: too much or too little water leads to poor adhesion or tiles sinking. Read how to avoid this in our blog “Common mistakes when mixing tile adhesive.”

Finally, insufficient adhesive coverage is often seen under tiles, leading to hollow spots and tiles loosening over time. The solution? Always use the correct trowel and proper technique.
