Unit of Competency MSFFL3048 - Select and fit diamond tools for concrete surface preparation and polishing
Description
Employability Skills
Learning Outcomes and Application This unit of competency covers selecting and fitting appropriate diamond grinding and polishing tools for use in concrete floor preparation and finishing machines. It applies to concrete cleaning and polishing operations on-site in commercial and residential environments and involves application of skills and knowledge at a sub-trade worker levelLicensing, 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).
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessors must:

hold training and assessment competencies as determined by the National Skills Standards Council (NSSC) or its successors

have vocational competency in the furnishing industry at least to the level being assessed with broad industry knowledge and experience, usually combined with a relevant industry qualification

be familiar with the current skills and knowledge used and have relevant, current experience in the furnishing industry.

Assessment methods must confirm consistency of performance over time rather than a single assessment event and in a range of workplace relevant contexts.

Assessment must be by observation of relevant tasks with questioning on underpinning knowledge and, where applicable, multimedia evidence, supervisor’s reports, projects and work samples.

Assessment is to be conducted on single units of competency or in conjunction with other related units of competency. Foundation skills are integral to competent performance in the unit and should not be assessed separately.

Assessment must occur on the job or in a workplace simulated facility with relevant process, equipment, materials, work instructions and deadlines.

Access is required to diamond grinding and polishing tools, planetary action grinders/polishers and manufacturer/user instructions and/or manuals.

Elements of Competency Performance Criteria              
Element: Identify the required concrete surface application
  • Concrete surface to be prepared and polished is examined to evaluate the level, any undulations and surface condition
  • Types of grinding and polishing techniques required for the job are established, including wet or dry application and any additional abrasives required
  • Floor moisture test results, where applicable, are evaluated to determine the floor grinding and polishing steps for the job
       
Element: Select diamond grinding tools
  • Required diamond tools and bond type for surface preparation are identified
  • Grit size for the grinding job is determined
  • Segments of diamond tool and bond type are matched to the job requirements and machine to be used for grinding
  • Diamond tools are fitted to the planetary machine for surface preparation operations ensuring tool rotation is correct for the machine set-up
       
Element: Select floor diamond polishing tools
  • Required diamond tools and bond type for surface polishing are identified
  • Grit size for the polishing job is determined
  • Segments of diamond tool and bond type are matched to the job requirements and machine to be used for polishing
  • Diamond tools are fitted to the planetary machine for surface polishing operations ensuring tool rotation is correct for the machine set up
       
Element: Clean up work area and tools
  • All diamond tools are examined to establish which are able to be re-used then cleaned and stored
  • Diamond tools that can no longer be used are identified, recorded in workplace documentation and disposed of in accordance with manufacturer recommendations
  • Work area is cleared and waste removed
