Description
This unit covers the competency to prepare, select and apply cementitious products using screeding techniques to concrete sub-floors prior to the installation of flooring coverings and coatings for internal and external applications.
Notes
Elements and Performance Criteria
1. Prepare for the work
  • 1.1. Applicable legislative, OHS and organisational requirements relevant to sub-floor preparation 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 to ensure that they are dry, smooth, plane, sound and clean in accordance with ASNZS 2455.2 (1995) and AS 1884 (1995) and the extent of preparation is confirmed
  • 1.4. Trial applications of surface materials are made to determine suitability of the primer to the sub-floor, and the appropriateness of the screed compounds to level requirements, and compatibility to the primer
  • 1.5. 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
  • 1.6. Material safety data sheets, or equivalent, are read and applied during the work
  • 1.7. Materials and equipment are prepared and positioned for use
  • 1.8. Surfaces are cleaned in accordance with manufacturer recommendation
2. From a datum line, define the grading, ramping and set downs
  • 2.1. Establish grid and mark the floor
  • 2.2. Drill for and position pin height
  • 2.3. Clean sub-floor
  • 2.4. Establish existing height and the height of finished ramp to the required threshold
  • 2.5. Establish the width of the ramp appropriate to the height of the finished threshold and in accordance with building codes and client requirements
  • 2.6. Establish existing height and the height of finished floor waste to the required threshold
  • 2.7. Establish height of finished floor at the perimeter
  • 2.8. Establish height of the finished floor at the floor waste/drain
3. Repair defects in sub-floor (including expansion joints)
  • 3.1. Establish extent of repairs required
  • 3.2. Remove unsound material and debris
  • 3.3. Determine type of materials to be used
  • 3.4. Prime affected area
  • 3.5. Mix and install repair compound
  • 3.6. Inspect completed work to ensure functionality is restored and the finish is plane and smooth
4. Treatment of expansion/control joints
  • 4.1. Establish the extent of repair
  • 4.2. Remove unsound material and debris to ensure the mechanics of the control/expansion joint are unimpeded
  • 4.3. Prepare joint to ensure that repair compound does not impede the function of control/expansion joint
  • 4.4. Prime affected area
  • 4.5. Mix and install repair compound
  • 4.6. Inspect completed work to ensure functionality of the control/expansion joint is not impeded
  • 4.7. Recut the expansion/control joint as required
5. Apply primers and screed compounds
  • 5.1. Surface coating is applied with the depth and coverage in accordance with manufacturer specifications and job requirements
  • 5.2. Levelled floor is checked and cleared for further processing
6. Complete housekeeping
  • 6.1. Unused materials are stored or recycled as required
  • 6.2. Tools and equipment are cleaned and stored appropriately
  • 6.3. Work area is cleaned and rubbish disposed of appropriately
  • 6.4. Workplace documentation and/or reporting is completed
RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Legislative requirements
are to be in accordance with applicable legislation from all levels of government that affect organisational operation. Requirements may include but not be limited to award and enterprise agreements, industrial relations, Australian Standards, confidentiality and privacy, OHS, the environment, equal opportunity, anti-discrimination, relevant industry codes of practice, duty of care and heritage
OHS requirements
are to be in accordance with Commonwealth, State or Territory legislation and regulations, organisational safety policies and procedures. Requirements may include but not be limited to the use of personal protective equipment and clothing, fire fighting equipment, First Aid equipment, hazard and risk control and elimination of hazardous materials and substances, manual handling including lifting and carrying
Organisational requirements
may include but not be limited to legal, organisational and site guidelines, policies and procedures relating to own role and responsibility, quality assurance, procedural manuals, quality and continuous improvement processes and standards, OHS, emergency and evacuation, ethical standards, recording and reporting, access and equity principles and practices, equipment use, maintenance and storage, environmental management (waste disposal, recycling and re-use guidelines)
Instructions
Workplace procedures relating to the use and operation of tools and equipment
Workplace instructions, including job sheets, plans, drawings and designs
Workplace procedures relating to reporting and communication
Manufacturer instructions for the use of equipment and materials
Sub-floor preparation
concrete sub-floor preparation may include sanding, grinding and the application of levelling compounds and primers
Level requirements
may refer to plane, falls to waste, and/or ramps to thresholds
EVIDENCE GUIDE
The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit
Interpret work order and locate relevant information
Apply safe handling requirements for equipment, products and materials, including use of personal protective equipment
Follow work instructions, operating procedures and inspection practices to:
prevent damage to goods, equipment and products
maintain required production output and product quality
minimise the risk of injury to self and others
Complete to Australian Standards a minimum of two sub-floor preparations which are to include:
a patch and repair
a level pour
Work effectively with others
Modify activities to cater for variations in workplace context and environment

Context of, and specific resources for assessment
The application of competency is to be assessed in the workplace or realistically simulated workplace
Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints
Assessment of essential underpinning knowledge, other than confirmatory questions, will usually be conducted in an off-site context
Assessment is to comply with relevant regulatory or Australian Standards requirements
The following resources should be made available:
workplace location or simulated workplace
materials and equipment relevant to sub-floor levelling activities
specifications and work instructions

Method of assessment
Assessment must satisfy the endorsed assessment guidelines of the Furnishing Industry Training Package
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application
Assessment may be applied under project related conditions (real or simulated) and require evidence of process
Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances
Assessment may be in conjunction with assessment of other related units of competency
