Application
This unit of competency covers applying plural component coatings, including polyurethane, polyester coatings and acid catalysed, to surfaces.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. | ||
1 | Prepare for work | 1.1 | Workplace information, including materials application and safety information, and material safety data sheets (MSDS), is used to inform work practices |
1.2 | Characteristics of the surface and the required surface treatment are identified from work orders or instructions | ||
1.3 | Processing and application techniques, time and safety requirements are identified and used for work planning | ||
1.4 | Work health and safety (WHS) requirements, including ventilation requirements and personal protection needs, are observed throughout the work | ||
1.5 | Tools, equipment and accessories are identified and checked for safe and effective application of plural component coatings | ||
2 | Prepare for application of materials | 2.1 | Surfaces are checked for contamination and correct preparation according to workplace procedures and standards |
2.2 | Products with surface or other faults are identified and faults repaired as appropriate | ||
2.3 | Materials required are identified and prepared for the task | ||
2.4 | 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 plural component coatings | ||
2.5 | Nitro-cellulose overspray is cleaned off booth surfaces if necessary before application of plural component coatings | ||
2.6 | Trial applications of plural component coatings are made to check equipment operation, materials consistency and viscosity | ||
2.7 | Faults and/or inconsistencies in applied coating are identified and workplace procedures for rectification and adjustment are followed | ||
3 | Apply finishing materials | 3.1 | Techniques for application of plural component coatings are identified and selected |
3.2 | Materials are applied according to job instructions, material manufacturer specifications and workplace procedures | ||
3.3 | Finished products are inspected and approved for suitability for further processing | ||
3.4 | Products which do not meet quality specifications are rectified or tagged for further investigation | ||
4 | Clean work area and maintain equipment | 4.1 | Equipment used is cleaned and inspected for serviceable condition and stored appropriately |
4.2 | Unserviceable equipment is tagged, faults are identified and appropriate personnel are informed | ||
4.3 | Work area is cleaned and returned to approved condition | ||
4.4 | Workplace records are completed | ||
Evidence of Performance
Interpret work order and locate and apply relevant information
Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
Identify materials used in the work process
Follow work instructions, operating procedures and inspection processes to:
minimise the risk of injury to self or others
prevent damage to goods, equipment and products
maintain required production output and product quality
Apply plural component coatings on at least three (3) occasions, including:
one (1) acid catalysed
one (1) two-part polyurethane
one (1) polyester
Maintain application equipment
Use mathematical ideas and techniques to correctly complete measurements, calculate area and estimate material requirements
Communicate ideas and information to enable confirmation of work requirements and specifications and the reporting of work outcomes and problems, interpret basic plans and follow safety procedures
Minimise wastage of resources, including materials, time and money
Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity
Evidence of Knowledge
Identification of application techniques
Characteristics of acid catalysed, polyurethane and polyester coatings
Methods to prevent contamination of surfaces during and after coating
Work flow in relation to the application of polyurethane and polyester
Assessment Conditions
Assessors must:
hold training and assessment competencies as determined by the National Skills Standards Council (NSSC) or its successors
have vocational competency in the furnishing industry at least to the level being assessed with broad industry knowledge and experience, usually combined with a relevant industry qualification
be familiar with the current skills and knowledge used and have relevant, current experience in the furnishing industry.
Assessment methods must confirm consistency of performance over time rather than a single assessment event and in a range of workplace relevant contexts.
Assessment must be by observation of relevant tasks with questioning on underpinning knowledge and, where applicable, multimedia evidence, supervisor’s reports, projects and work samples.
Assessment is to be conducted on single units of competency or in conjunction with other related units of competency. Foundation skills are integral to competent performance in the unit and should not be assessed separately.
Assessment must occur on the job or in a workplace simulated facility with relevant process, equipment, materials, work instructions and deadlines.
Access is required to spray application equipment, acid catalysed, polyurethane and polyester coatings.
Foundation Skills
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency. Detail on appropriate performance levels for each furnishing unit of competency in reading, writing, oral communication and numeracy utilising the Australian Core Skills Framework (ACSF) are provided in the Furnishing Training Package Implementation Guide.
