What type of mortar is commonly recommended for porcelain tiles?

Thin-set mortar is commonly recommended for porcelain tiles due to its versatility, bonding strength, and suitability for the specific characteristics of porcelain. Porcelain tiles are denser and less porous than other types of tiles, which means they require a mortar that can effectively adhere to their surfaces without compromising stability. Thin-set mortar, typically made from a blend of cement, fine sand, and additives, provides a strong bond that can handle the weight and low absorbency of porcelain tiles.

Moreover, thin-set (modified or unmodified) can be tailored to meet different conditions, such as those found in wet areas or high-traffic applications. The flexibility of thin-set mortar allows it to accommodate movement that may occur in the flooring or substrate without cracking or losing adhesion, making it especially suitable for use with porcelain tiles.

Other types of mortar have their specific applications and limitations; for instance, epoxy mortar offers excellent durability and moisture resistance but is usually more suited for specialized installations or areas exposed to extreme conditions. Mastic mortar is best for lighter wall tiles and is not recommended for heavier floor tiles like porcelain. Sand-mix mortar is more commonly used for setting bed installations rather than directly adhering tiles.
