Install wall linings and encasement systems
This element covers the preparation and installation of wall linings and encasement systems, typically using plasterboard on timber or metal frames, direct bonding (dot and dab), or encasing structural steel for fire protection. Learners must demonstrate correct setting out, material handling, fixing, and finishing to meet industry standards and building regulations, ensuring completed work is plumb, level, and ready for decoration or further finish.
Assessment criteria
Quick Revision Summary (Key Takeaway)
The City & Guilds Level 2 Diploma in Dry Lining covers the skills and knowledge required to install dry lining systems, including plasterboard, metal stud partitions, and finishing techniques. This qualification prepares learners for a career in construction, focusing on safe working practices, interpreting drawings, and applying high-quality finishes.
Topic Overview
Dry lining is a modern construction method used to create internal walls and ceilings without wet trades. It involves fixing plasterboard to either timber or metal frames, providing a smooth, ready-to-finish surface. This diploma equips learners with the practical skills to measure, cut, and install plasterboard, as well as to apply jointing and finishing compounds to a professional standard.
The qualification covers essential health and safety practices, including the correct use of personal protective equipment (PPE) and safe handling of materials. It also introduces learners to interpreting technical drawings and specifications, which is crucial for ensuring accurate installation. Dry lining is widely used in both residential and commercial projects, making these skills highly sought after in the construction industry.
Mastery of dry lining techniques contributes to the overall quality and efficiency of building projects. It also provides a foundation for further qualifications in plastering, site supervision, or specialist dry lining systems. By the end of this diploma, students will be confident in working independently or as part of a team, with a strong understanding of industry standards and best practices.

- Award credit for correct selection and safe use of hand and power tools specific to dry lining, including mixing adhesives, cutting boards, and driving fixings.
- Award credit for setting out lines, levels, and positions accurately from a datum, ensuring openings and junctions align with design.
- Award credit for installing wall linings plumb, level, and flush, with correct board orientation, staggered joints, and appropriate fixing centres.
- Award credit for constructing encasement systems with specified fire-rated materials, maintaining required clearances and fire-stopping integrity.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always reference the manufacturer’s data sheet during practical tasks to justify your installation methods—this shows competence in sourcing information.
- 💡During oral questioning, clearly explain the sequence of setting out and the consequences of deviations, such as how a 3mm error can accumulate across a wall.
- 💡Photograph or log quality checks throughout the process (e.g., plumb checks, board type verification) to provide a full evidence trail for your portfolio.
- 💡Practice identifying common defects and their remedies, as assessors often ask how you would rectify a specific non-compliance or installation fault.
- 💡Always use the correct technical terminology, such as 'track', 'stud', 'plasterboard', and 'jointing compound', to demonstrate your knowledge.
- 💡In practical exams, pay attention to measurement accuracy and cutting techniques, as these are common areas where marks are lost.
- 💡When answering theory questions, refer to relevant building regulations and safety standards to show a professional understanding.
Common Mistakes
Common errors to avoid in your coursework
- Failing to properly prime or damp-proof substrates before dot and dab application, leading to poor adhesion or moisture damage.
- Incorrect board orientation (e.g., running boards vertically when horizontal is specified) or mixing board types within a fire-rated system.
- Inadequate fixing of timber or metal studwork, causing movement or lack of rigidity once boarded.
- Over- or under-mixing adhesive, leading to insufficient bond strength or excessive setting time.
- Neglecting to install movement joints or control measures at door openings or long runs, causing cracking.
- Incorrectly assuming all encasement systems are identical—using the wrong board type or sealant for a given fire rating.
- Misconception: All plasterboard is the same. Correction: Different boards have different properties (e.g., moisture resistance, fire rating) and must be selected based on the location and building regulations.
- Misconception: Screws should be driven deep into the board to ensure a strong fix. Correction: Screws should be countersunk just below the surface without tearing the paper, as over-driving weakens the board and affects the finish.
- Misconception: Jointing tape is optional if the compound is applied thickly. Correction: Tape reinforces the joint and prevents cracking; it is essential for a durable finish.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A room measures 4m by 3m with a ceiling height of 2.4m. Calculate the total area of plasterboard required to cover the walls and ceiling, assuming no openings. Show your working.
- 1.Step 1: Calculate the perimeter of the room: 2 × (4m + 3m) = 14m.
- 2.Step 2: Calculate the wall area: perimeter × height = 14m × 2.4m = 33.6m².
- 3.Step 3: Calculate the ceiling area: length × width = 4m × 3m = 12m².
- 4.Step 4: Add wall and ceiling areas: 33.6m² + 12m² = 45.6m².
Question: Describe the correct procedure for installing a metal stud partition, including the tools and fixings used. (6 marks)
- 1.Step 1: Mark out the partition position on the floor and ceiling using a chalk line and plumb bob.
- 2.Step 2: Fix the floor and ceiling tracks (U-channels) using appropriate fixings (e.g., masonry nails or screws) at 600mm centres.
- 3.Step 3: Position the vertical studs (C-channels) at 600mm centres, ensuring they are plumb and secured with self-tapping screws.
- 4.Step 4: Cut and fix plasterboard to one side, then install insulation (if required) and services, then fix the second side.
