Learners will demonstrate competence in surface preparation, adhesive application, tile setting, and grouting to achieve a professional finish compliant with industry standards.
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 different types of tiles and their uses. By the end of the course, you'll be able to complete basic tiling tasks safely and to a professional standard.
This diploma is part of the Construction & Building Services suite and provides a solid foundation for further study or entry-level employment. It's designed for beginners with no prior experience, making it an ideal starting point. The skills you gain are directly applicable to real-world tiling jobs, from domestic bathrooms to commercial kitchens. Mastering these basics is crucial because even simple mistakes—like poor surface preparation or incorrect adhesive mixing—can lead to costly failures. The course emphasises precision, patience, and attention to detail, which are key to producing durable, attractive tiled surfaces.
In the wider context of construction, wall and floor tiling is a specialist trade that combines practical craftsmanship with technical knowledge. Tilers work alongside other trades such as plasterers, plumbers, and electricians, so understanding how your work fits into a larger project is important. This diploma not only teaches you how to tile but also how to plan your work, estimate materials, and communicate effectively with clients and colleagues. It's a stepping stone to the Level 2 Diploma, where you'll tackle more complex patterns, substrates, and commercial projects.
Key Concepts
Core ideas you must understand for this topic
- →Surface preparation: Substrates must be clean, dry, flat, and sound. For walls, this often means applying a suitable primer or waterproofing membrane; for floors, self-levelling compound may be needed to create a level base.
- →Tile layout and setting out: Always start from the centre of the wall or floor and work outwards to ensure balanced cuts at edges. Use a chalk line or laser level to mark reference lines before fixing any tiles.
- →Adhesive selection and mixing: Different tiles (ceramic, porcelain, natural stone) require specific adhesives. Mix to the manufacturer's instructions—too wet or too dry will compromise bond strength. Use a notched trowel at the correct angle to achieve full coverage.
- →Cutting techniques: Use a manual tile cutter for straight cuts on ceramic tiles, an electric wet saw for harder materials or complex cuts, and tile nippers for small curves or notches. Always wear PPE when cutting.
- →Grouting and finishing: Apply grout with a rubber float, pressing firmly into joints. Wipe off excess before it dries, then polish with a dry cloth. Seal grout if required to prevent staining and moisture ingress.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct mixing and application of tiling adhesives in accordance with manufacturer's instructions.
- Award credit for accurately setting out tiles to ensure symmetry, minimal cuts, and adherence to design specifications.
- Award credit for fixing tiles with full bed coverage, ensuring no voids and adequate adhesion, especially in wet areas.
- Award credit for applying grout evenly, tooling joints to a consistent depth and finish, and removing excess without smearing or residue.
- Award credit for correctly applying silicone sealant to joints and corners, achieving a neat, continuous bead with no gaps.
- Award credit for demonstrating correct assessment of background suitability, including testing for moisture content, surface flatness, and key preparation prior to tiling.
- Award credit for accurately mixing and applying tile adhesive using the correct trowel notch size and achieving full coverage in accordance with manufacturer specifications.
- Award credit for fixing tiles plumb, level, and with consistent joint widths, while incorporating any required movement joints and trims.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always perform a dry lay to visualise the layout, identify cuts, and confirm that patterns align before fixing.
- 💡Check that backgrounds are dry, clean, sound, and free from contamination before commencing any preparation work.
- 💡Use a spirit level and straightedge continuously throughout tiling to ensure consistent alignment and plane across the surface.
- 💡Clean tools and minimise waste as you work; assessors frequently award marks for good housekeeping and systematic approach.
- 💡For finishing, buff off any residual grout haze with a clean, dry cloth once the grout has fully hardened to avoid a cloudy appearance.
- 💡Always reference manufacturer's instructions when justifying material choices and application methods in written assessments.
- 💡During practical assessments, demonstrate a systematic approach: check background, prepare materials, apply adhesive methodically, and clean as you go to show professional working practices.
- 💡In knowledge-based questions, link your answers to British Standards (e.g., BS 5385) to show deeper understanding of industry requirements.
- 💡In practical assessments, pay close attention to your setting out. Examiners look for symmetry and minimal small cuts at edges. Always measure twice and cut once—a well-planned layout saves time and materials.
- 💡Demonstrate safe working practices throughout: wear appropriate PPE (gloves, goggles, knee pads), keep your work area tidy, and use tools correctly. Marks are awarded for method as well as the final result.
- 💡When answering theory questions, use technical terms correctly (e.g., 'substrate' not 'wall', 'adhesive' not 'glue'). Show you understand the 'why' behind each step, not just the 'how'.
Common Mistakes
Common errors to avoid in your coursework
- Failing to adequately prime or dampen backgrounds before applying adhesives, leading to poor bond and tile de-bonding.
- Using the incorrect notch trowel size for the selected adhesive and tile format, causing inadequate coverage or adhesive slump.
- Neglecting to use tile spacers or levelling systems, resulting in uneven joints and lippage between tiles.
- Grouting before adhesive has fully set, which can stain porous tiles or weaken the installation.
- Overlooking the need for expansion and movement joints in large floor areas or where substrates change, leading to cracking.
- Failing to prime porous backgrounds before tiling, leading to poor adhesion and tile failure.
- Incorrect mixing of cementitious adhesives, either adding too much water or not allowing proper slaking time.
- Neglecting to account for tile layout and cuts, resulting in unsightly slivers of tile at edges or around fixtures.
- Misconception: You can tile directly onto painted walls. Correction: Paint must be removed or keyed with a suitable primer; otherwise, tiles will not adhere properly and may fall off.
- Misconception: More adhesive means a stronger bond. Correction: Too much adhesive can cause tiles to slip or create uneven surfaces. The correct notched trowel size ensures the right amount for full coverage without excess.
- Misconception: Grout is just for looks and can be applied immediately after tiling. Correction: Grout provides structural support and prevents water damage. Wait at least 24 hours after fixing tiles before grouting to allow adhesive to cure fully.
