How to choose tiles for a large surface

The choice of tiles depends on several criteria such as the size of a space or its use (commercial or residential). It is important to take into consideration aesthetic criteria, but also practical ones. In this article, we give you advice on choosing your large format tiles and present the standards to be respected for a large surface.

To dress the floor of this type of space, there are large format tiles that are more suitable than others. Here are the main criteria to take into account when making your choice.

The size of the tiles

For large surfaces, it is preferable to opt for large format tiles. Generally speaking, the sizes used are 60 x 60 cm, 80 x 80 cm, or even larger. These formats reduce the number of joints and create a space that appears larger and more homogeneous. Using large tiles can also make maintenance easier by minimizing the joint lines, where dirt tends to accumulate.

What color and patterns for large-scale tiles?

Light colors are often preferred in large areas to visually enlarge the space and bring in brightness. However, white is not necessarily the best shade for this type of space because it makes all the marks visible. Beige or light gray may be more suitable. In large areas, simple patterns or plain tiles are preferable to avoid an overly busy effect.

The finish of the tiles

There are several types of finishes for large-format tiles. We advise you to opt for a matte model. This will make your floor less slippery and will not highlight marks and dirt as a glossy coating could do. Semi-polished tiles can offer a good compromise between the aesthetics of gloss and the practicality of matt.

What is the best material for large-surface tiles?

For a large-surface floor, the priority is durability, resistance to stains and shocks, and ease of maintenance. For this, porcelain stoneware is an excellent choice. It can be glazed or in full mass. This second option is ideal for high-traffic areas due to its robustness.

What type of tile installation should you choose for a large surface?

The type of tile installation should not be left to chance. There are several:

• The straight installation: is the most classic, it gives an orderly effect.
• The diagonal installation: is used to visually enlarge a space. It must be accompanied by aligned joints to have an appropriate width.

Whatever the type of installation chosen, it is essential to prepare the ground in advance and ensure that it is well leveled. The use of spacers is also essential to obtain regular and clean joints.

In this type of space, it is important to choose a large format tiles that meets quality and hygiene standards. Here are the main standards to consider when making your choice.

Quality standards for large surface tiles

The European standard EN 14411 governs the technical specifications of ceramic tiles. This includes dimensions, flatness, resistance to breakage and water absorption. It ensures that the tiles meet strict manufacturing and performance criteria in order to guarantee their quality and durability.
The Porcelain Enamel Institute (PEI) rating measures the resistance of the tile surface to wear. Ratings range from PEI 1 (very light traffic) to PEI 5 (very heavy traffic). For large surfaces, it is essential to opt for a model classified PEI 4 or PEI 5.

Safety standards for large format tiles

The R standard (non-slip) evaluates the level of grip of the tiles. The classifications range from R9 to R13, where R13 is the most non-slip. In areas subject to humidity, a classification between R11 and R13 is recommended to avoid the risk of slipping.
The water absorption capacity is also a significant criterion in the choice of tiles for large surfaces to limit the risk of falls. In spaces exposed to humidity, water absorption must be less than 0.5%. This is the case, for example, with porcelain stoneware, which is perfect for passage areas.
The ISO 13006 / ASTM C373-18 standard is specific to large format tiles intended for intensive commercial use. It ensures its increased resistance to impact and wear. This is essential to ensure its durability.

Standards for the maintenance of large format tiles

It is essential to choose tiles that are resistant to chemical products to facilitate their maintenance and ensure their durability. This is all the more important in commercial spaces where frequent cleaning with aggressive products may be necessary. We advise you to choose a model whose resistance to acids, alkalis and cleaning products has been tested and approved.
By following these tips and respecting these standards, you can be sure to choose a tile suitable for a large surface that is functional, safe, aesthetic, easy to maintain and durable.
