What is the adhesive used for installing large format tiles often referred to as?

The adhesive used for installing large format tiles is often referred to as medium-bed mortar. This type of mortar is specifically formulated to provide better support and stability for larger tiles, which can be heavier and more prone to sagging than standard-sized tiles.

Medium-bed mortar contains a thicker consistency compared to traditional thin-set mortar, allowing it to accommodate the larger tiles more effectively. It is designed to minimize lippage – the unevenness between adjacent tiles – and ensures a secure bond that can withstand the weight of the large format tiles over time. The properties of medium-bed mortar, including its improved workability and grab, make it suitable for such installations, providing the necessary coverage and adhesion required for success.

Using the appropriate adhesive is crucial for achieving a long-lasting and aesthetically pleasing tile installation, particularly when dealing with larger formats.
