Most Common Mistakes When Installing Floor and Wall Tiles (And How to Avoid Them)
The quality of a floor or wall covering does not depend solely on the material you choose. In fact, poor installation can compromise its durability, cause cracks, loose tiles, and even increase maintenance costs. For this reason, understanding the most common installation mistakes is essential to achieving a long-lasting and professional finish.
1. Failing to Level the Subfloor Before Installation
One of the most common mistakes is installing flooring on an uneven surface. As a result, uneven areas, loose tiles, and cracks may develop over time.
How to avoid it: Before installation begins, make sure the subfloor has been properly measured and levelled. In addition, ask for this step to be clearly specified in the quotation to ensure it is carried out correctly.
2. Purchasing the Wrong Amount of Material
Buying less material than required can delay the project, especially if the same product is no longer available. On the other hand, purchasing too much results in unnecessary costs.
How to avoid it: Carefully calculate the installation area and allow for a wastage margin of between 7% and 15%, depending on the type of flooring and the complexity of the cuts. Whenever possible, have these calculations confirmed by your supplier or installer.
3. Choosing Flooring Based Only on a Sample
A small sample does not always accurately represent the colour, finish, or overall appearance of the flooring once installed over a larger area. In addition, lighting conditions can significantly affect how the material looks.
How to avoid it: Request a larger sample or a full-size tile and view it at different times of the day under both natural and artificial lighting. This will help you make a more confident decision.
4. Overlooking Expansion Joints
Expansion joints are essential because they allow materials to naturally expand and contract as temperatures change. When they are omitted, the flooring may lift, crack, or even break.
How to avoid it: Plan expansion joints according to technical standards and the dimensions of the installation area. This significantly reduces the risk of future damage and helps extend the lifespan of the flooring.
Avoiding these common mistakes is an important step towards achieving a durable, safe, and beautifully finished floor. Alongside choosing high-quality materials, work with qualified professionals and follow best installation practices to ensure results that will remain attractive for many years.
