Wall and floor tiling refers to the laying of tiles of ceramics, mosaic and natural stone on walls, floors and staircases in houses, industrial and public buildings, churches, swimming pools, outside installations and façades to provide protective and decorative finishes. It also includes the construction of small walls and steps from bricks or blocks.

Tilers work from diagrams and instructions. First, they measure the area to be tiled and calculate the minimum number of tiles required. Next, they remove any existing covering. They then prepare the surface - levelling the floor using sand and cement, or applying plaster if they are tiling a wall. They then spread cement or adhesive with a trowel and lay the tiles in the desired pattern. They may have to cut tiles to fit around walls and obstacles.

After the adhesive has dried, the joints between the tiles are filled with grouting cement. On large projects, tilers may work in teams. On smaller jobs, they often work alone.

Experienced tilers may also specialise in one area of work, such as mosaics. They can work for specialist tiling firms, firms specialising in artistic work and for some building contractors. Many tilers are self-employed sub-contractors.
