The ceramic industry produces ever larger tiles over the years. Today tile layers are facing sizes over 4 square meters.

These mega formats are demanding: they require great skill in laying and very flat substrates. Builders want tiles with as few joints and joint widths as possible.
In addition to above-average technical skills, this type of installation requires special knowledge, creativity and specially adapted products.

In particular the preparation of the substrate should be carried out professionally. As a rule, the substrate for large formats requires additional levelling to improve the evenness.

In addition to the familiar substrate test, it is important to know that the evenness tolerances (for ex. described in DIN 18202) are often not sufficient for this type of installation. They may have to be optimized by the application of an additional levelling compound on in the wall or floor area.

Large formats in the outdoor area

Tile and natural stone coverings on balconies and terraces must be much more resistant than other covering surfaces, as they are exposed to frost, rain and solar radiation over the long term.
