Screeding is a process which involves using liquid concrete to level out and smooth the surface of a floor space to ensure that it is a uniform height and to prepare it for tiling. In many cases, screeding is also used to create falls, which are directional levels for drainage purposes. Screeding is considered the foundation to ensuring a tiling project results in a perfect finish.
Screeding is essential to many aspects of tiling because it is unfortunately common that fresh slabs in new home developments may not be poured correctly and thus be out of level. Also in established homes where a renovation is undertaken, the structure may have moved over time due to the ground underneath, causing floors or walls or ceilings to be slightly out of level which then in turn affects the quality of the finished tiling work. Areas affected include, but are not limited to: shower bases, balconies, structural levelling of main floor areas in bathrooms, living rooms and kitchens.
