The UNE 138002: 2023 standard in large format tile installation

The ceramics industry has experienced great technological advances in recent decades, with the development of large format ceramics being one of the most prominent. These tiles, characterised by their size, offer impeccable aesthetics and the ability to reduce visible joints, offering a uniform and contemporary design.

However, their size and weight present particular challenges in their installation. The correct installation and finishing of these products is essential to ensure their durability and aesthetics, and this is where the UNE 138002:2023 standard becomes relevant.

1. Standard 138002:2023: Quality Assurance

Standard 138002:2023 has been established to provide specific guidelines on the correct installation of ceramic tiles. This technical document is a response to the sector’s need to establish quality criteria and good practice in tile installation. The standards set out in this standard ensure correct adhesion, levelling and alignment of the tiles, resulting in long-lasting installations.

2. Large Format Ceramics: A Technical Challenge

Large format ceramics require special attention due to their characteristics. It is essential that the substrates are perfectly level and clean before laying, and it is crucial to use high performance adhesives to ensure proper adhesion.

The double gluing technique, in which the adhesive is applied to both the substrate and the tile, is essential and must be complied with in order to guarantee correct installation and optimum results. In addition, specific tools and equipment are necessary for the correct handling and laying of these tiles.

3. Grouting: A Fundamental Element for Durability

The grouting process is not simply a final aesthetic step, but is of great importance for the durability of the ceramic system. A correct grouting protects the edges of the ceramic tiles, avoids the infiltration of water and other liquids. In addition, its technical function is to act as an element that absorbs stresses between pieces, thus reducing the risk of breakage or detachment.

The UNE 138002:2023 standard establishes specific criteria on the type of grout to be used, the waiting time before starting the process and the application technique. All this with the aim of achieving a durable and resistant ceramic tile installation system.

4. Durability of the Placement System

Correct installation and finishing not only guarantees impeccable aesthetics, but also ensures greater durability of the system. A poorly laid tile or poor grouting can lead to problems such as spalling, leaks or the appearance of pathologies on the tile surface. By following the 138002:2023 standard, the risk of these problems is drastically reduced, extending the life of the tile and minimising the need for corrective maintenance.

Conclusion

The UNE 138002:2023 standard represents an essential reference framework for all professionals in the ceramics sector. Its rigorous compliance guarantees large-format ceramic tile installation systems that are not only aesthetically pleasing, but also durable and resistant. In a market that is increasingly demanding in terms of quality and durability, it is essential to adhere to the best technical standards and practices.
