Elements and Performance Criteria

1. Identify the sub-floor properties
   • Applicable work health and safety (WHS), legislative and organisational requirements relevant to the use of appropriate compounds and additives are verified and complied with
   • Instructions and/or plans are read and interpreted to identify the process required to complete work tasks
   • Appropriate personal protective equipment is selected, correctly fitted and used
   • The type of floor and wall construction and the building floor and wall structure and sub-structure are identified
   • Datum lines are run and checked to confirm dimensions
   • Timber and/or concrete flooring inspections are completed to identify irregularities
   • Wall inspections are completed to identify irregularities
2. Select appropriate compounds and additives
   • Types of floor and wall preparation compounds and additives and their functions are identified from relevant information sources
   • Sub-floors and walls are checked for contamination, moisture content, plane, smooth and suitable preparation
   • Suitable compounds and additives are selected consistent with the needs of the job
3. Prepare compounds and additives
   • Tools, equipment and materials are selected and checked prior to use to ensure that they are appropriate for the work, serviceable and in a safe condition
   • Selected compounds and additives for application are organised and prepared in accordance with relevant safety management requirements
   • The method of application is selected
   • Sequence of work is planned to ensure the application of appropriate compounds and additives is in logical order
4. Apply compounds and additives
   • Working lines are established and starting point is selected
   • Mixing station is established and selected compounds and additives are mixed to manufacturer instructions
   • Selected compounds and additives are applied to the sub-floor surface following manufacturer instructions
   • Sub-floors are inspected and re-worked as required
5. Complete housekeeping
   • Tools and equipment are cleaned and stored appropriately
   • Work area is cleaned and rubbish disposed of appropriately
   • Workplace documentation is completed
