Task B-5 Evaluates and prepares surface
Task Descriptor
Substrate preparation is a key step of a finished tile, stone or terrazzo project. It ensures the ease in subsequent procedures and the longevity of the finished product. Tilesetters determine and evaluate the conditions of the substrate for deficiencies such as cracks, holes, level and deterioration and prepare the surface accordingly. Substrate preparation may involve the installation of membranes, mortar beds and underlayments. Skills and knowledge related to mixing materials for mortar beds can be found in the Task D-11, Mixes materials.
