MSFFL3047 Polish concrete floors using planetary machines

Modification History

Release 1 - New unit of competency

Application

This unit of competency covers selecting and operating floor surfacing machines designed for wet or dry polishing of concrete floors. It applies to concrete cleaning and polishing operations in on-site commercial and residential environments and involves application of skills and knowledge at a sub-trade worker level.

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. Access to construction sites requires certification of general induction training specified by the National Code of Practice for Induction for Construction Work (ASCC 2007).

Elements and Performance Criteria

Elements describe the essential outcomes.	Performance criteria describe the performance needed to demonstrate achievement of the element.
1	Select concrete polishing equipment	1.1	Planetary concrete grinding/polishing equipment and attachments are selected consistent with the needs of the job
1.2	Hand edge and corner polishing tools are selected consistent with the needs of the job
1.3	Equipment is checked for serviceability and safety and any faults are corrected or processed for repair
2	Clean and prepare sub-floor	2.1	Applicable work health and safety (WHS), legislative and organisational requirements relevant to polishing concrete floors are followed including selecting, correctly fitting and using personal protective equipment
2.2	Fittings, fixtures, loose debris, dirt and other items are removed from the sub-floor
2.3	Sub-floor is inspected to determine the need for removal of existing adhesive, paint or other contaminants
2.4	Planetary polishing machine, appropriate machine rotation speed, direction and diamond tools are selected for removal of contaminants
2.5	Machine is attached to a suitable power supply, emergency stop is released, the machine powered up and contaminants are removed in accordance with manufacturer specifications
3	Polish the floor	3.1	Machine is attached to a suitable power supply, emergency stop is released, the machine powered up, a passing pattern established and main area is polished to the required standard in accordance with manufacturer specifications
3.2	Outer zones are overlapped and passes staggered to achieve desired finish
3.3	Machine operation is monitored constantly to ensure motor/motors are running within manufacturer’s safe operational limits and no electrical faults are evident
3.4	Perimeter of the designated area is polished using edge and corner polishing equipment and appropriate attachments
3.5	Diamond polishing tools are examined for wear and exchanged, when required, throughout the polishing process
3.6	Excessive wear of polishing tools is recognised and remedial action taken as required
3.7	Floor area is cleaned, inspected and re-worked as required
4	Clean up work area and tools	4.1	All tools and grinding/polishing equipment are cleaned, maintained and stored
4.2	Equipment is cleaned, maintained and stored
4.3	Work area is cleared and waste removed

Foundation Skills

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency. Detail on appropriate performance levels for each furnishing unit of competency in reading, writing, oral communication and numeracy utilising the Australian Core Skills Framework (ACSF) are provided in the Furnishing Training Package Implementation Guide.

Range of Conditions

Specifies different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Range is restricted to essential operating conditions and any other variables essential to the work environment.

Types of concrete polishing equipment and supplies include:	single headed, double headed and planetary action grinders/polishers dust/vacuum systems diamond abrasives
Selection of diamond tool segments includes:	half set (for contaminant removal e.g. glue when a flat floor finish is not required) full set (for flattening)
Diamond abrasive wear includes influence of:	hardness of material being ground (e.g. aggregate and sand abrasiveness) the grinding/polishing pressure hardness of the bond diamond grit size number of segments presence of water use of additional abrasives
