Elements and Performance Criteria
- Prepare for work
- Workplace information, including materials application and safety information, material safety data sheets, is used to inform work practices
- Characteristics of the surface and the required surface treatment are identified from work orders or instructions
- Processing and application techniques, time and safety requirements are identified and used for work planning
- OHS requirements, including ventilation requirements and personal protection needs, are observed throughout the work
- Tools, equipment and accessories are identified and checked for safe and effective application of polyurethane, polyester and acid catalysed coatings
- Prepare for application of materials
- Surfaces are checked for contamination and correct preparation according to workplace procedures and standards
- Products with surface or other faults are identified and faults repaired as appropriate
- Materials required are identified and prepared for the task
- Spray booths and work documentation are inspected to ensure nitro-cellulose lacquer has not been sprayed in the same booth as that used for the application of two/three part polyurethane/polyester coatings
- Nitro-cellulose overspray is cleaned off booth surfaces if necessary before application of two/three-part polyurethane/polyester
- Trial applications of two-part polyurethane/polyester and acid catalysed coatings are made to check equipment operation, materials consistency and viscosity
- Faults and/or inconsistencies in applied coating are identified and workplace procedures for rectification and adjustment are followed
- Apply finishing materials
- Techniques for application of plural component coatings are identified and selected
- Materials are applied according to job instructions, material manufacturer specifications and workplace procedures
- Finished products are inspected and approved for suitability for further processing
- Products which do not meet quality specifications are rectified or tagged for further investigation
- Clean work area and maintain equipment
