Learning Objectives
What you need to know and understand
- Analyse site specifications and floor plans to determine the type, thickness, and extent of screed to be removed and replaced.
- Identify the key requirements of the CDM Regulations, COSHH, and Manual Handling Operations Regulations when removing and renewing floor screeds.
- Demonstrate correct selection and use of personal protective equipment (PPE) and respiratory protective equipment (RPE) during screed removal and renewal.
- Evaluate the condition of the substrate and carry out appropriate preparation, including priming and damp-proof membrane installation, prior to laying new screed.
- Calculate precise material quantities from given data to avoid waste and ensure sufficient supply for the work area.
- Apply techniques to contain dust, protect adjacent surfaces, and manage waste in line with environmental and site-specific requirements.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurately interpreting work instructions, including drawings and written specifications, to plan the screed removal and renewal sequence.
- Look for evidence of selecting the correct type and quantity of screed material, additives, and reinforcement as per the specification.
- Assess the candidate’s method of existing screed removal; checking for controlled breakout to prevent damage to the subfloor and surrounding structures.
- Confirm that the candidate tests substrate moisture levels and applies bonding agents or primers correctly before new screed application.
- Verify that the finished screed is level, compacted, and cured in accordance with manufacturer’s guidelines, with minimal deviation from specified datum.
- Check that all waste materials are segregated and disposed of in compliance with site waste management plans.
Assessment Guidance
Guidance for achieving higher grades
- 💡Provide a photographic record of each stage—existing floor condition, preparation, mixing, laying, and finished work—to create a clear evidence trail for assessment.
- 💡Keep a contemporaneous diary noting material batch numbers, mix proportions, ambient conditions, and any issues encountered to demonstrate professional practice.
- 💡Always cross-reference your work against the contract specification and manufacturer’s data sheets; state this explicitly in your witness testimony or written answers.
- 💡Always use the correct technical terminology in your answers, such as 'stopcock' instead of 'tap' for water isolation.
- 💡Show your working in calculations, even if the answer is obvious, to gain method marks.
- 💡Link your answers to relevant regulations, such as the Health and Safety at Work Act, to demonstrate professional knowledge.
Common Mistakes
Common errors to avoid in your coursework
- Failing to identify or address substrate defects (cracks, dampness) before laying new screed, leading to adhesion failure or future cracking.
- Overlooking the need for movement joints or incorrectly positioning them, resulting in uncontrolled cracking in large floor areas.
- Inaccurate water-to-mix ratios when mixing screed, causing poor workability, reduced strength, or extended drying times.
- Misconception: You only need to know one trade well. Correction: The qualification requires competence across multiple trades, so you must develop basic skills in each.
- Misconception: Safety is just about wearing gloves and a hard hat. Correction: It involves risk assessments, safe use of tools, and following procedures like isolating utilities.
- Misconception: Measuring and cutting accurately is not critical. Correction: Inaccurate measurements lead to wasted materials and poor finishes, so precision is vital.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A rectangular room measures 5.5 m by 4.2 m. You need to lay new floor tiles that are 0.3 m by 0.3 m. Calculate the number of tiles required, assuming a 10% waste allowance for cutting and breakages.
- 1.Step 1: Calculate the floor area: 5.5 m × 4.2 m = 23.1 m².
- 2.Step 2: Calculate the area of one tile: 0.3 m × 0.3 m = 0.09 m².
- 3.Step 3: Divide floor area by tile area: 23.1 ÷ 0.09 = 256.67 tiles. Round up to 257 tiles.
- 4.Step 4: Add 10% waste: 257 × 1.10 = 282.7, so round up to 283 tiles.
Question: Describe the steps to replace a damaged section of plasterboard on an internal wall, including the tools and materials needed.
- 1.Step 1: Identify the damaged area and cut out a rectangular section using a plasterboard saw, ensuring clean edges.
- 2.Step 2: Measure the opening and cut a new piece of plasterboard to fit, leaving a small gap (2-3 mm) for jointing.
- 3.Step 3: Fix the new piece using drywall screws into the studwork, ensuring the surface is flush.
- 4.Step 4: Apply jointing tape and joint compound over the seams, then sand smooth after drying.
- 5.Step 5: Finish with a skim coat of plaster or paint as required.
