Ceramic Tiles and Porcelain Tiles Q&A Part 1

What is mortar?

The setting material used to bond tiles to a given surface is called mortar. Different types of mortar are available for different backing and conditions.

What is the mortar bed?

The final coat of mortar on a wall, floor or ceiling is called a mortar bed. It is the layer of mortar on which tile is set. This is also referred to as the installation bed.

What is the mortar joint?

Joint composed of, or embedded in, cement mortar is called mortar joint.

Will ceramic tile chip and crack?

Once installed, ceramic tiles become a permanent part of your structure, and will not chip or crack unless hit with a heavy object. However, prior to installation, it is a very brittle product and can be easily cracked, fractured or snapped, if handled carelessly.

What is meant by chemical resistance of tile?

The ability of a tile surface to withstand damage from chemicals, acids, alkalis and swimming pool salts in accordance with ISO testing methods is termed as chemical resistance.

What is matte glaze?

Glaze that produces a non-shiny finish is known as matte glaze.

What is meant by bisque?

Bisque or 'Biscuit Body' is the body of a ceramic tile, made by a refined mixture of clay, minerals, water and additives - shaped and fired (unglazed) in the kiln. These raw materials also give the bisque its strength and stability.

The strength of the bisque is determined by its density. The strongest bisques (suited for heavy commercial installations) have the smallest and least number of air pockets. The density of the clay also determines if the tile is suitable for outdoor use. Porous tiles i.e., those absorbing more than 3% moisture will freeze and crack if installed outdoors in cold climates.
