Tiling of Large Format Porcelain Tile

Temperature and ambient humidity

Due to changes in temperature and relative humidity, when the floor expands and shrinks, large format porcelain tile produced from a different material also changes in different ratios. 
This may be due to the following reasons:

• The tile adhesive layer, which is the application surface, can be reduced in volume during the setting process.
• Expansion may occur in hot climatic conditions.
• Extensive contact with water may result in moisture-related expansion.

Floor movement caused tension on large format tile

When a dimensional deviation occurs on a non-rigid surface, the rigid coating material will not deviate in the same way.  The difference that the Porcelain tile  will attempt to close for a certain amount of dimensional deviation on the surface will be greater in Porcelain tile materials. As such a condition will cause higher stress, the adhesive must have a more elastic structure to prevent problems with such large format Porcelain tile.
