Application
This unit of competency covers preparing concrete sub-floors and applying moisture barriers and damp proof membranes in readiness for the installation of floor coverings and coatings.
Licensing, legislative or certification requirements may apply to this unit and relevant state/territory and local government agencies should be consulted to determine any necessary certification or licensing for undertaking flooring work. Access to construction sites requires certification of general induction training specified by the National Code of Practice for Induction for Construction Work (ASCC 2007).
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 | Applicable work health and safety (WHS), legislative and organisational requirements relevant to moisture barriers and damp proof membranes are verified and complied with |
1.2 | Instructions and/or plans are read and interpreted to identify the process required to complete work tasks | ||
1.3 | Sub-floors are inspected in accordance with Australian Standards and treatment system identified | ||
1.4 | Tools, equipment and materials are selected and checked prior to use to ensure that they are appropriate for the work, serviceable and in a safe condition | ||
1.5 | Material safety data sheets (MSDS), or equivalent, are read and applied during work | ||
1.6 | Materials and equipment are prepared and positioned for use | ||
1.7 | Surfaces are cleaned in accordance with manufacturer recommendations | ||
2 | Apply moisture suppressant | 2.1 | Surface coating is applied with the depth and coverage in accordance with manufacturer specifications and job requirements |

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
Complete two (2) moisture suppressant/barrier installations:
one (1) moisture barrier (dealing with an external moisture problem that may be due to hydrostatic pressure or capillary action)
one (1) moisture suppressant (dealing with construction moisture in green concrete)
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
Avoid backtracking, work flow interruptions or wastage
Work with others and in a team by recognising dependencies and using cooperative approaches to optimise work flow and productivity
Evidence of Knowledge
State or territory WHS legislation, regulations, standards and codes of practice relevant to moisture suppressants and barrier systems
Organisational and site standards, requirements, policies and procedures for moisture suppressant and barrier systems
Environmental protection requirements
Established communication channels and protocols
Relevant problem identification and resolution
Types of tools and equipment and procedures for their safe use, operation and maintenance
Characteristics of materials, products and defects
Types, application and features of moisture barriers and moisture suppressant techniques
Set-up and operation of equipment
Procedures for the recording, reporting and maintenance of workplace records and information
Appropriate mathematical procedures for estimation and measurement
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 materials and equipment relevant to moisture suppressant/barrier activities and their specifications.
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.
Range Statement
