What is a key purpose of using specialized mortars in tiling?

Using specialized mortars in tiling primarily serves to improve bonding and setting properties. These mortars are formulated to create a strong adhesion between the tile and substrate, which is crucial for the long-term performance and durability of the installation. The right type of mortar can accommodate the specific requirements of different tile materials, such as porcelain or natural stone, which may have varying porosity and surface characteristics. Additionally, these specialized mortars can include additives that enhance flexibility, moisture resistance, and curing times, all of which contribute to a solid and reliable installation.

The enhancement of aesthetic appeal, reduction of tile weight, and simplification of installation, while perhaps beneficial in certain contexts, are not primary reasons for the use of specialized mortars. The main focus remains on ensuring that the tiles adhere properly and set correctly, which is essential for preventing issues such as cracking, lifting, or water infiltration over time.
