Elements and Performance Criteria

1. Match coating to substrate.
   • Identify substrate to be used.
   • Determine requirements of final coated surface.
   • Recommend appropriate coating system.
2. Recommend preparation and application techniques.
   • Recommend substrate preparation.
   • Select appropriate coating application equipment
   • Determine required rheology of coating
   • Specify required coating tests
   • Specify coating application
3. Analyse problems with surface coatings.
   • Identify non-conformances in coated product
   • Distinguish between preparation, application and paint problems
   • Recommend correct preparation and application to prevent problems.

Required skills

This competency includes the following skills analysis selection discrimination maths

Required knowledge

Competence in this unit includes the following knowledge Material Safety Data Sheet OHS requirements calculate VOC levels different types of application equipment brush roller paint pad various spray applications electrostatic dip hot melt flow coating powder coating reasons for prevention of corrosion methods used to prepare common substrates for application of a coating knowledge of atmospheric conditions ie temperature humidity and dew point identify substrate coating surface defects methods than can be used to prevent paint defects in both wet and dry film defects explain the different types of test procedures and test equipment impact of the final coating if substrate preparation not adequate identification of appropriate substrates and their uses reasons for the selection of coatings on the customer substrate identify the reasons for different types of application equipment problems that may arise if incorrect equipment is recommended the reasons for compliance coatings issues surrounding volatile organic compoundsVOC problems that may arise if incorrect coating is recommended effects of shear in surface coatings characteristics of shear rates and their importance in coating application the effect of rheology on surface coatings adequate tests and equipment to identify correct rheological properties differing types of paint defects dry paint filmswet films the correct preparation the potential effects of climate and other environmental influences on both the coating and substrate decorative requirements such as colour gloss and texture the customer requirements specific service conditions such as impact abrasion and general wear and tear and their affect on the final coating

Evidence Required

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 the Training Package
Overview of assessment	Assessment of this unit should include demonstrated competence on actual plant and equipment in a work environment The unit will be assessed in as holistic a manner as is practical and may be integrated with the assessment of other relevant units of competency Assessment will occur over a range of situations which will include disruptions to normal smooth operation Simulation may be required to allow for assessment of parts of this unit Simulation should be based on the actual plant and will include walkthroughs of the relevant competency components Simulations may also include the use of case studiesscenarios and role plays This unit of competency requires a significant body of knowledge which will be assessed through questioning and the use of whatif scenarios both on the plant during demonstration of normal operations and walkthroughs of abnormal operations and off the plant
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Consistent performance should be demonstrated In particular look to see that paint defects can be identified and corrected correct selection of the coating to the required substrate implement correct equipment for the required application maintain a safe working environment assess problem situations and initiate effective corrective action the many types of application methods
Context of and specific resources for assessment	Assessment will require access to an operating plant over an extended period of time or a suitable method of gathering evidence of operating ability over a range of situations A bank of scenarioscase studieswhatifs will be required as will a bank of questions which will be used to probe the reasoning behind the observable actions
Method of assessment	In all plants it may be appropriate to assess this unit concurrently with other relevant units
Guidance information for assessment	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

Range Statement

The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicized wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts.
Codes of practice/ standards	Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used. Particular standards of relevance include: AS 2311 "Painting of Buildings" AS1580 "Paints & related materials-test methods" AS 2310 "Glossary of Paint and Painting Terms" AS 3978 "Non destructive testing-visual inspection of metal products and components" AS 3894 Site testing of protective coatings"
Context	This competency applies to technical staff to provide the correct advice to customers for the application of surface coatings to required substrates.
Health, safety and environment (HSE)	All operations to which this unit applies are subject to stringent health, safety and environment requirements, which may be imposed through State or Federal legislation, and these must not be compromised at any time. Where there is an apparent conflict between Performance Criteria and HSE requirements, the HSE requirements take precedence.
