- Identify the work of increasing cladding supports in the construction sector, classifying the different types of applications and their purposes, and specifying methods and work sequence. - Apply installation techniques for the usual auxiliary and collective protection means in the execution of screeds, collaborating in their installation and correcting the deficiencies of those already installed, complying with specific health and safety measures. - Contrast the state of the supports and the environmental conditions for the application of different mortar screeds, both walkable and non-walkable, proposing treatments for each support and determining the environmental conditions that allow the application of the screed mixtures. -Dose the screed mixtures - mortars and concretes - and check their properties when fresh, considering the nature and conditions of the possible supports, and the environmental conditions. - Apply screed techniques - mortar and lightened concrete - leveled on walkable elements, on possible supports and in radiant air conditioning systems, selecting the equipment that best adapts to a given job, placing the insulation and complying with the specific quality and safety and health measures.
