Elements and Performance Criteria

1. Prepare for work
   • Characteristics of the surface and the required surface coating are identified from work orders or instructions
   • Processing and application techniques, time and safety requirements are identified and used for work planning
   • Work health and safety (WHS) 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 operation for the surface coating task
   • Coating materials are identified and prepared
2. Check and prepare for spraying
   • Products with surface or other faults are identified and faults reported or repaired as appropriate
   • Other products and equipment in the workplace are protected from overspray
   • Trial applications of surface materials are made to check equipment operation, materials consistency and specified surface finish
   • Machine faults are identified and rectified or reported
   • Material faults are identified and workplace procedures for rectification are followed
3. Apply surface coating
   • Surfaces are kept free of contamination
   • Surface coatings are applied according to workplace procedures
   • Surface coating viscosity and coverage is monitored and checked against workplace requirements for even spread and thickness
   • Rectification of surface faults are made as required
   • Products are inspected and approved for suitability for further processing
   • Defects are dealt with and/or reported in accordance with workplace procedures
4. Clean work area and maintain equipment
   • Equipment is cleaned and inspected for serviceable condition and stored appropriately
   • Unserviceable equipment is tagged, faults are identified and appropriate personnel are informed
   • Work area, including spray booth is cleaned and returned to approved condition
   • Workplace records are completed
