Preparing tiles for fixing to wall and floor installations
This element focuses on the essential preparatory steps before fixing tiles, including inspecting, sorting, and grading tiles for defects, correct storage, and cutting tiles and trims to required sizes and profiles. Learners develop practical skills to handle materials efficiently, minimise waste, and ensure a high-quality finish in wall and floor tiling projects.
Assessment criteria
Topic Overview
The City & Guilds Level 1 Diploma in Wall and Floor Tiling introduces you to the fundamental skills and knowledge required to start a career in tiling. This qualification covers essential techniques such as preparing surfaces, measuring and cutting tiles, mixing adhesives, and fixing tiles to walls and floors. You'll also learn about health and safety practices, selecting appropriate tools and materials, and understanding basic design principles. Mastering these basics is crucial because they form the foundation for more advanced tiling work and ensure you can produce professional, durable results.
This diploma is part of the Construction & Building Services sector and is designed for those with little or no previous experience. It provides a stepping stone to further qualifications, such as the Level 2 Diploma, or direct entry into an apprenticeship. The skills you gain are highly practical and transferable, making you employable in a range of settings, from domestic bathrooms to commercial kitchens. By the end of the course, you'll be able to confidently tackle small tiling projects and understand the standards expected in the industry.
Key Concepts
Core ideas you must understand for this topic
- →Surface preparation: Ensuring substrates are clean, dry, flat, and sound before tiling. This includes removing old adhesive, filling holes, and applying primer if needed.
- →Adhesive selection and mixing: Choosing the correct adhesive for the tile type (e.g., cement-based for ceramics, epoxy for natural stone) and mixing it to the right consistency to achieve a strong bond.
- →Cutting tiles: Using tools like manual cutters, electric saws, or tile nippers to make straight cuts, L-shaped cuts, and curved cuts around obstacles.
- →Setting out and spacing: Planning the tile layout to minimise cuts, using spacers for consistent grout lines, and ensuring patterns are aligned and level.
- →Grouting and finishing: Applying grout to fill joints, cleaning excess grout, and sealing tiles if required to protect against moisture and stains.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct visual inspection of tiles for chips, cracks, shade variation, and calibration before cutting.
- Award credit for selecting and safely using appropriate cutting tools (manual cutter, wet saw, angle grinder) for straight cuts, L-shaped cuts, and circular holes.
- Award credit for accurately measuring and marking tiles with a pencil or gauge, allowing for joint width and waste.
- Award credit for correctly cutting trim lengths with mitred joints for internal and external corners, free from burrs.
- Award credit for demonstrating accurate measurement and transfer of dimensions onto tiles and accessories using appropriate marking tools (e.g., pencil, chinagraph, scribe).
- Look for evidence of selecting the correct cutting method (manual snap cutter, wet saw, angle grinder) based on tile material and required cut shape.
- Assess the learner's ability to consistently produce clean, accurate cuts with minimal chipping, ensuring cut edges are smoothed or dressed appropriately.
- Expect learners to organise materials and work area systematically, showing awareness of health and safety regulations including PPE use and dust suppression.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always double-check measurements and mark the tile’s glazed side to minimise errors during cutting.
- 💡Practice multiple cutting techniques on scrap tiles to build confidence and demonstrate precision in assessed tasks.
- 💡In coursework evidence, include annotated photographs showing each preparation stage, from sorting tiles to finished cuts.
- 💡In practical assessments, always narrate your process to the assessor, explaining safety checks and rationale for tool selection to demonstrate underpinning knowledge.
- 💡Prioritise accuracy over speed; carry out a dry lay of cut tiles before fixing to confirm fit, as errors here are more costly than extra time spent.
- 💡Familiarise yourself with the specific cutting characteristics of common tile types (ceramic, porcelain, natural stone) as questions may test your material-specific knowledge.
- 💡For written exams, use correct terminology such as 'snap line', 'scribe', 'nibble', and 'back-buttering' to convey professional competence.
- 💡Always check your setting out before cutting any tiles. A common mistake is starting from a corner without considering the centre of the room, leading to awkward small cuts at the edges. Use a chalk line to mark reference lines.
- 💡When cutting tiles, measure twice and cut once. Use a pencil to mark the cut line, and always wear safety goggles. For curved cuts, use tile nippers and take small bites to avoid cracking.
- 💡In the practical assessment, keep your work area clean and organised. Examiners look for good housekeeping as it shows professionalism and attention to detail.
Common Mistakes
Common errors to avoid in your coursework
- Failing to check and sort tiles by batch number or shade, leading to colour mismatch after fixing.
- Using a tile cutter with a dull scoring wheel or insufficient pressure, resulting in jagged or uneven breaks.
- Measuring cutting dimensions without accounting for the grout joint, causing tiles not to fit correctly.
- Neglecting to wear appropriate PPE when cutting, particularly eye protection when using power saws or angle grinders.
- Failing to double-check measurements before cutting, resulting in irreversible material wastage and ill-fitting tiles.
- Using excessive force with manual cutters on hard tiles, causing breakage or jagged edges, rather than scoring and snapping in a controlled manner.
- Neglecting to allow for expansion gaps or cutting tiles too tightly, leading to later failures or cracking in the installation.
- Not accounting for the pattern repeat or directional veining when cutting decorative tiles, causing visual inconsistencies in the fixed finish.
- Myth: You can tile directly onto painted walls. Correction: Paint must be removed or keyed (scratched) to allow adhesive to bond; otherwise, tiles may fall off.
- Myth: More adhesive means a stronger bond. Correction: Too much adhesive can cause tiles to slip or create uneven surfaces; use the correct notch trowel size and apply adhesive evenly.
- Myth: Grout is waterproof. Correction: Grout is porous and can absorb water; it should be sealed (if not epoxy) to prevent staining and moisture damage.
