Elements and Performance Criteria

  1. Match coating to substrate
  2. Recommend preparation and application techniques
  3. Analyse problems with surface coatings

Range Statement

This field allows for 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.

Regulatory framework

The latest version of all legislation, regulations, industry codes of practice and Australian/international standards, or the version specified by the local regulatory authority, must be used, and include one or more of the following:

AS/NZS 2311:2009 Guide to the painting of buildings

AS 1580 (Set) Paints and related materials – Methods of test

AS/NZS 2310:2002 Glossary of paint and painting terms

AS 3978-2003 Non-destructive testing – Visual inspection of metal products and components

AS 3894 (Set) Site testing of protective coatings

legislative requirements, including work health and safety (WHS)

industry codes of practice and guidelines

environmental regulations and guidelines

Australian and other standards

licence and certification requirements

All operations to which this unit applies are subject to stringent health, safety and environment (HSE) requirements, which may be imposed through state/territory 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.

Hazards

Hazards include one or more of the following:

equipment failures

flammability and explosivity

hazardous products and materials

slippery surfaces, spills or leaks

extreme weather

other hazards that might arise

Procedures

All operations must be performed in accordance with relevant procedures.

Procedures are written, verbal, visual, computer-based or in some other form, include one or more of the following:

emergency procedures

work instructions

standard operating procedures (SOPs)

safe work method statements (SWMS)

formulas/recipes

batch sheets

temporary instructions

any similar instructions provided for the smooth running of the plant



Knowledge Evidence

Evidence must be provided that demonstrates knowledge of:

types and application of application methods and application equipment (e.g. brush, roller, paint pad, various spray applications, electrostatic, dip, hot melt, flow coating and powder coating)

impact of atmospheric conditions (i.e. temperature, humidity and dew point)

effects of shear in surface coatings, characteristics of shear rates and their importance in coating application

the potential effects of climate and other environmental influences on both the coating and substrate

specific service conditions, such as impact, abrasion and general wear and tear and their effect on the final coating

preparation methods for common substrates

methods than can be used to prevent paint defects in both wet and dry film defects

different types of test procedures and test equipment

impact of the final coating if substrate preparation not adequate

problems that may arise if incorrect equipment is recommended

the reasons for compliance coatings

problems that may arise if incorrect coating is recommended

the effect of rheology on surface coatings

adequate tests and equipment to identify correct rheological properties

differing types of paint defects (dry paint films/wet films)

decorative requirements, such as colour, gloss and texture

organisation procedures

duty of care obligations

hierarchy of control

hazards that may arise in the job/work environment, and:

their possible causes

potential consequences

appropriate risk controls.
