Construction Trade Occupations - Tiling — City and Guilds of London Institute Vocationally-Related Qualification Construction & Building Services Revision
This subtopic covers fundamental tiling within construction trades, focusing on safe practices, correct tool use, surface preparation, adhesive application
Topic Synopsis
This subtopic covers fundamental tiling within construction trades, focusing on safe practices, correct tool use, surface preparation, adhesive application, tile fixing, grouting, and finishing to vertical surfaces. Learners must demonstrate practical competence in preparing backgrounds, setting out tiles, cutting and fixing wall tiles, and restoring the work area to a clean and safe condition, all while strictly adhering to health and safety legislation such as the Health and Safety at Work Act and COSHH regulations.
Key Concepts & Core Principles
- Health and safety regulations: Understand COSHH, risk assessments, and the correct use of PPE to prevent accidents on site.
- Basic tool identification and use: Know the names and purposes of hand tools (e.g., trowels, hammers, saws) and power tools (e.g., drills, sanders).
- Material properties: Recognise common construction materials like bricks, blocks, timber, and plasterboard, and their typical applications.
- Measuring and marking out: Accurately use tape measures, spirit levels, and squares to mark cutting lines and check levels.
- Simple construction techniques: Perform basic tasks like laying bricks to a line, cutting timber with a saw, and applying paint with a roller.
Exam Tips & Revision Strategies
- When answering written questions on health and safety, always reference specific legislation and apply it to a tiling scenario, not just general construction. For example, explain how COSHH relates to mixing tile adhesive in a confined space.
- In practical assessments, take time to set out your work logically: start with a gauging rod to plan tile arrangements, avoid small cuts at edges, and ensure your first row is perfectly level.
- For the task of restoring the work area, document or demonstrate that you sweep, wipe down surfaces, dispose of waste responsibly, and check for any damage to tools or surrounding surfaces before leaving.
Common Misconceptions & Mistakes to Avoid
- Misunderstanding the hierarchy of control measures required by COSHH, often failing to identify the correct personal protective equipment (PPE) for handling tile adhesives and grouts.
- Using a notched trowel incorrectly, resulting in insufficient adhesive coverage or ridges that are not fully collapsed, leading to hollow-sounding tiles.
- Neglecting to check backgrounds for plumb and level before starting, causing misaligned tile rows and uneven lipping that requires rework.
- Attempting to cut tiles without proper marking or using incorrect cutting methods, resulting in breakages, chipped edges, and material wastage.
- Failing to clean excess grout from tile faces in time, leaving a stubborn haze that requires additional chemical or abrasive cleaning, damaging the finish.
Examiner Marking Points
- Accurately identify and describe the purpose of key health and safety legislation, including the Health and Safety at Work Act and COSHH, as it applies to tiling activities.
- Select and safely use appropriate tiling tools and equipment (e.g., notched trowel, spirit level, tile cutter) for the task, explaining their correct maintenance and storage.
- Demonstrate correct surface preparation by checking for plumb, level, and soundness, and applying primer or bonding agent where necessary before tiling.
- Show accurate setting out and fixing of tiles to a vertical surface with consistent joints and full adhesive coverage, using a notched trowel at the correct angle.
- Complete tiling to a professional standard by applying grout evenly, cleaning excess grout promptly, and reinstating the work area to a clean, safe condition after completion.
