Application
This unit describes the performance outcomes required to prepare vehicle substrates for refinishing by removing surface rust and scale, and applying primers and sealers before the final refinishing. It involves preparing for the task, selecting and using specialist tools and equipment, selecting and using materials, cleaning vehicle substrate surfaces according to manufacturer specifications, and completing workplace processes and documentation.
It applies to those working in the automotive paint refinishing repair industry. The preparation of plastic or composite materials for refinishing is not addressed in this unit.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
Elements Elements describe the essential outcomes. | Performance Criteria Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section. |
1. Prepare for work | 1.1 Job requirements are determined from workplace instructions 1.2 Preparation information is accessed and interpreted 1.3 Vehicle or component is inspected to identify substrate paint film builds 1.4 Materials are selected and inspected for quality 1.5 Hazards associated with the work are identified and risks are managed 1.6 Refinishing tools and equipment and personal protective equipment (PPE) are selected and checked for serviceability 1.7 Work is planned to identify vehicle substrate preparation methods, minimise waste, and prevent damage to vehicle |
2. Remove surface rust and apply primers | 2.1 Surface rust and scale are removed from substrate using approved methods, materials and equipment and according to workplace procedures and safety and environmental requirements 2.2 Substrate components affected by application processes are protected or removed without causing damage to vehicle or components 2.3 Surfaces to be painted are cleaned and contaminants are removed 2.4 Primers and primer surfaces are applied using approved methods, materials and equipment |

Assessment Conditions
Assessors must satisfy NVR/AQTF assessor requirements.
Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.
Assessment must include direct observation of task.
Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the vehicle substrates that they have prepared for refinishing, e.g. repair orders.
Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.
The following resources must be made available:
automotive repair workplace or simulated workplace
workplace instructions
TDS and SDS for primers and chemical cleaners
PPE required to prepare substrates for refinishing
materials required to prepare substrates for refinishing
vehicle substrates specified in the performance evidence requiring preparation for refinishing
tools, equipment and materials appropriate for preparing vehicle substrates for refinishing.
