Application
This unit of competency covers sanding and filling of parquetry floors in preparation for applying coating or re-coating to the flooring. It involves operating split drum/belt floor sander, rotary or orbital sanding and edge sanding machines.
Licensing, legislative or certification requirements may apply to this unit and relevant State and local government agencies should be consulted to determine any necessary certification or licensing for undertaking flooring work. Access to construction sites requires certification of general induction training specified by the National Code of Practice for Induction for Construction Work (ASCC 2007).
