Unit Descriptor
Unit descriptor
This competency covers the application of surface coatings by hand, spray gun or immersion and the resolving of routine problems to procedure.
Application of the Unit
Application of this unit
This competency applies to operators who are required to apply surface coatings to products by hand, spray gun or immersion. It is typically performed by operators working either independently or as part of a work team. The operator will:
- check the surface of products to be coated for imperfections or contamination
- check materials for conformity to job requirements
- apply the surface coating material
- notice any problems and take required actions (eg reporting)
- deal with non-conforming products, waste and scrap
- complete logs and reports
They may record key variables such as machine conditions and production rate and reasons for interruptions.
This unit does not include:
- packing of product - see MSASUP204A Pack products or materials
- finishing of product - see PMBFIN201 Finish products and components .

Required Skills and Knowledge
This describes the essential skills and knowledge and their level required for this unit.
Application of knowledge of the materials, equipment and process sufficient to recognise out of specification products, process problems and materials faults.
Knowledge of organization procedures, quality requirements and relevant regulatory requirements along with the ability to implement them within appropriate time constraints and work standards.
Application of the knowledge of managing risk using the hierarchy of controls applied to the coating process. Application of approved hazard control and safety procedures and the use of PPE in relation to handling materials, equipment operation and cleanup
Knowledge and skills in the operation of the surface coating process and equipment sufficient for consistent production of quality products, including:
- production workflow sequences and materials demand
- correct selection and use of equipment or tool/s, materials, processes and procedures
- accurately monitoringequipment operation and product quality
- reasons for checking process control panels and reporting readings which are outside of the normal range of process variability
- identifying factors which may affect product quality or production output and appropriate remedies
- potential effectsof variations in materials and equipment operation in relation to quality of product
- processing behaviour of polymers and the role of additives
- effect of unauthorised or emergency work stoppage in relation to safety and production requirements
- waste management and knowing the importance of reusing non-conforming products wherever possible
- basic pre-blending of materials
- application of coatings.
Competence also includes the ability to:
- plan own work, including predicting consequences and identifying improvements
- identify when the operator is able to rectify faults, when assistance is required and who is the appropriate source for assistance
- identify and describe own role and role of others involved directly in the coating process.
Language , literacy and numeracy requirements
This unit requires the ability to read and interpret typical product specifications, job sheets, procedures, material labels and safety information as provided to operators.
Writing is required to the level of completing workplace forms.
Basic numeracy is required, eg to determine that two 25 kg bags are needed to make up a requirement for 50 kg.
Evidence Guide
The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, required skills and knowledge, the Range Statement and the Assessment Guidelines for this Training Package.
Overview of assessment
A holistic approach should be taken to the assessment.
Assessors must be satisfied that the person can consistently perform the unit as a whole, as defined by the Elements, Performance Criteria and skills and knowledge.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:
- apply the required skills and knowledge to operate surface coating equipment
- apply approved procedures.
Consistent performance should be demonstrated. For example, look to see that:
- surface coating production standards are met consistently
- all safety procedures are followed.
Assessment method and context
Assessment will occur using industrial surface coating equipment and will be undertaken in a work-like environment
Competence in this unit may be assessed:
- using appropriate surface coating equipment or tool/s requiring demonstration of operation and emergency stop procedures
- in a situation allowing for the generation of evidence of the ability to respond to problems
- by using suitable simulation and/or a range of case studies/scenarios
- through a combination of these techniques.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.
Specific resources for assessment
This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
