Course Curriculum

Select and maintain materials, tools and equipment for specified plastering work

  • Materials, tools and equipment properties, purposes, and applications are described according to their
  • Materials, tools and equipment are selected for specified tasks (fit-for-purpose).
  • Materials, tools and equipment are checked against manufacturers’ specifications and criteria contained in work plans, in order to implement corrective action if any defective or faulty materials, tools and equipment do not meet prescribed requirements.


Prepare work areas for plastering

  • Work areas are identified, measured and set out according to specifications provided.
  • Work tasks are communicated and agreed to according to specified procedures.
  • Areas are identified for batching and mixing plaster in order to meet requirements for proximity to specific work areas/transport.


Batch and mix plaster

  • Unsuitable materials are identified and removed before mixing.
  • Plaster mixes are batched according to specifications and work requirements.
  • Batch sizes are checked to ensure that mixes are used before stiffening.
