Unit Of competency

Modification History

Release 1. Supersedes and is equivalent to MSFFL3047 Polish concrete floors using planetary machines

Application

This unit describes the skills and knowledge required to select, prepare and use floor surfacing machines and their attachments for wet or dry polishing of concrete floors. It applies to concrete cleaning and polishing operations in commercial and residential environments.

This unit applies to flooring technicians working in accordance with pre-determined work orders.

Licensing, legislative or certification requirements may apply to this unit and relevant state/territory and local government agencies should be consulted to determine any necessary certification or licensing for undertaking flooring work. Industry standards and codes of practice within Australia must also be applied. Access to construction sites requires certification of general induction training specified by the National Code of Practice for Induction for Construction Work (ASCC 2007).
