CPC31020 Solid Plastering study guide
CPC31020 Solid Plastering · Work through your exam, one topic at a time.
The CPC31020 Solid Plastering credential is an Australian qualification for tradespeople who apply plaster, render and decorative finishes to internal and external surfaces. It suits apprentices working toward trade recognition, experienced plasterers formalising skills gained on site, and workers moving into solid plastering from related trades such as bricklaying or tiling. The CPC31020 Solid Plastering study guide has 8 sections and about 2,799 words.
01Workplace Health, Safety and Environmental Practice
Solid plastering carries risks that are easy to underestimate: silica dust from cutting and mixing, lime burns to skin and eyes, cement dermatitis, musculoskeletal strain from trowelling and lifting, and falls from trestles and scaffolds. Questions in this domain test whether you can link a hazard to a control, and whether you know the hierarchy of control rather than jumping straight to PPE.
408 words, about 2 min02Interpreting Drawings, Specifications and Work Instructions
A plasterer works from a set of documents that only make sense together: architectural and reflected ceiling plans, elevations, sections, detail drawings, the specification, the schedule of finishes, and the builder's work instructions or site instructions. Questions in this domain test whether you read the right document for the question asked, and whether you can extract a dimension or a specification without being misled.
364 words, about 2 min03Selecting, Preparing and Maintaining Tools, Plant and Equipment
Good plastering depends on tools that are clean, correctly broken in and suited to the material. This domain tests tool knowledge, preparation and maintenance routines, and safe use of plant such as mixers, spray machines and hoists.
367 words, about 2 min04Measuring, Setting Out and Preparing Backgrounds and Surfaces
Most plaster failures trace back to preparation: dusty, friable, too absorbent or too smooth backgrounds, or missing keys and beads. This domain tests measurement, setting out datums and lines, and the preparation of masonry, concrete, plasterboard and existing plaster.
329 words, about 2 min05Applying Solid Plaster to Walls, Ceilings and Internal Surfaces
Internal solid plastering is a sequence of coats applied at the right thickness and the right time. Questions test coat order and purpose, thickness limits, and how to avoid shrinkage cracking and poor adhesion.
334 words, about 2 min06Applying Render and External Solid Plaster Finishes
External render has to survive rain, sun, movement and salt, so the rules differ from internal work. This domain tests mix design, suction control, movement joints and the causes of external defects.
325 words, about 2 min07Producing Decorative and Specialist Plaster Finishes
Decorative finishes are judged on consistency and intent, not uniformity. This domain tests the materials, tools and sequences for textured, coloured and specialist finishes, plus the mock-up discipline that keeps a job consistent.
325 words, about 2 min08Quality Control, Defect Rectification and Site Clean-up
Quality control is a cycle: check the work against the specification at each stage, record what you find, rectify defects at the right time, and leave the site clean. This domain tests defect identification, causes and remedies, and the standard of finish expected.
