1. Skipping Proper Surface Preparation

Most tiling issues start long before a single tile is laid. If the surface is uneven, dusty, or unstable, it can lead to cracks or failed adhesive.
At Coventry Tiling, every project begins with a full surface assessment and preparation. We prime, level, and reinforce where needed, ensuring a solid base that guarantees the tiles stay secure for years to come.

2. Using the Wrong Adhesive

Different tiles and substrates require specific adhesives. Porcelain, natural stone, and large-format tiles each have unique demands.
We always use high-performance, manufacturer-approved adhesives that are matched to the material, environment, and substrate to ensure durability and strength.

3. Incorrect Trowel Size or Coverage

Too little adhesive coverage leads to hollow spots, loose tiles, or cracking. For floors and heavy-use areas, full coverage is essential.
Our installers use the correct trowel size for each format and back-butter larger tiles to achieve perfect bonding across every tile.

4. No Decoupling Membrane Over Movement Areas

Where old floors meet new screeds or cracks are present, movement can easily transfer through to the tiles.
We identify problem areas before tiling begins and install decoupling membranes such as Schluter DITRA or similar systems to protect against cracks and stress.

5. Poor Layout and Planning

A rushed layout can ruin the symmetry of a room and leave awkward cuts in visible areas.
We carefully plan every layout, marking centre lines and running dry tests to ensure perfect balance and alignment before tiling begins.

6. Rushed Grouting or Wrong Grout Choice

Grouting before the adhesive has fully cured, or using the wrong type of grout, can lead to cracking, weak joints, or uneven colouring.
At Coventry Tiling, we always allow the correct drying time before grouting and select premium flexible or epoxy grouts to suit the environment — whether it’s a wet room, bathroom, or high-traffic floor — ensuring a strong, consistent finish that lasts.

7. Neglecting Silicone and Finishing

Even with perfect tiling, poor finishing can ruin the overall look.
We take finishing seriously. Every silicone line, trim, and detail is applied with precision using colour-matched, mould-resistant products for a seamless result.
