Tile wall surfaces
This element focuses on the practical skills and underpinning knowledge required to tile wall surfaces to industry standards. Learners will develop the ability to interpret technical drawings and specifications to determine material quantities and layout, select appropriate adhesives and tiles for various substrates, and apply tiling techniques that ensure a durable, aesthetically pleasing finish. Mastery of these competencies is essential for working effectively on construction sites and meeting client expectations.
Assessment criteria
Topic Overview
The City & Guilds Level 2 Diploma in Wall and Floor Tiling is a vocational qualification designed to equip you with the practical skills and theoretical knowledge needed to start a career as a professional tiler. This diploma covers everything from preparing surfaces and cutting tiles to fixing them in place and applying grout, ensuring you can work safely and to industry standards. It's a key stepping stone for anyone looking to work in construction, whether on new builds, renovations, or commercial projects.
Throughout the course, you'll learn about different types of tiles (ceramic, porcelain, natural stone) and the correct adhesives and grouts for each. You'll also develop skills in setting out tile layouts, using cutting tools like manual cutters and electric saws, and achieving a high-quality finish. Health and safety is a major focus, including manual handling, working at heights, and using personal protective equipment (PPE). By the end, you'll be able to plan and complete tiling jobs independently, meeting the standards expected by employers and clients.
This diploma fits into the broader construction industry by providing a specialist skill that is in high demand. Tiling is a finishing trade that adds value and aesthetics to buildings, and qualified tilers can progress to supervisory roles, start their own business, or specialise in areas like heritage restoration or large-format tiles. The qualification is recognised across the UK and is often a requirement for apprenticeships or entry-level positions with contractors.
Key Concepts
Core ideas you must understand for this topic
- →Surface preparation: Ensuring substrates are clean, dry, flat, and primed to prevent tile failure.
- →Tile layout and setting out: Using spacers and chalk lines to create symmetrical patterns and avoid small cuts at edges.
- →Adhesive selection and application: Choosing the right adhesive for the tile type and substrate, and applying it with the correct notch trowel size.
- →Cutting techniques: Using manual cutters, electric saws, and hole cutters for accurate cuts, including internal and external corners.
- →Grouting and finishing: Applying grout to fill joints, cleaning excess, and sealing tiles where necessary for a professional finish.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurately calculating tile quantities and cut dimensions from scaled drawings and job specifications.
- Assessor to check that selected adhesive and grout are compatible with substrate type, tile material, and service conditions (e.g., wet areas).
- Evidence must include correct substrate preparation, such as priming and leveling, before tiling commences.
- Examine finished work for uniform joint width (2-3mm typical), even alignment, and full adhesive coverage without hollow spots.
- Ensure that tiling sequence follows setting out plan, with cuts neatly finished and positioned appropriately (e.g., at corners or edges).
- Award credit for accurately interpreting working drawings to determine tiling layout, starting points, and any special features such as borders or insets.
- Award credit for selecting tiles, adhesives, and grouts that are compatible with the substrate, exposure conditions, and design requirements as per project specification.
- Award credit for preparing the wall surface to be flat, clean, and sound, with any necessary priming or tanking prior to tiling.
- Award credit for setting out the wall using gauge rods and spirit levels to minimise cuts and ensure symmetrical appearance, marking horizontal and vertical datum lines.
- Award credit for applying tiles uniformly, with consistent joint widths, full bed adhesive coverage, and correct alignment, finishing with clean grouting and silicone sealant at internal corners.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always cross-reference the drawing with the written specification; highlight key points like tile pattern, grout colour, and height of tiling.
- 💡In practical assessments, take time to set out accurately, use a spirit level and chalk lines to establish vertical and horizontal guidelines.
- 💡Practice calculating tile layout to minimise wastage and avoid slivers; examiners look for efficient material use.
- 💡Demonstrate safe working practices, including proper PPE and mixing adhesives to manufacturer's guidelines, as marks are often allocated for health and safety.
- 💡For coursework, document each stage with photos and annotations to evidence decision-making and compliance with specifications.
- 💡Always cross-reference the specification with the drawing schedule to confirm tile type, adhesive colour, and joint width before starting work.
- 💡Use a spirit level and straightedge to mark accurate vertical and horizontal lines; stepping back frequently to check alignment avoids cumulative errors.
- 💡Present a range of tile cuts in your assignment evidence, demonstrating competency with manual and mechanical cutters for L-shaped, straight, and complex cuts.
- 💡Document all preparation stages with photographs to provide clear evidence of meeting marking criteria, including substrate checks and any remedial work.
- 💡In practical assessments, always check your surface is level and plumb before starting. Use a straightedge and spirit level – this shows you understand the importance of preparation.
- 💡When setting out, measure and mark your centre lines carefully. Symmetry is key, and examiners look for balanced layouts with minimal small cuts.
- 💡For theory questions, use technical terms like 'substrate', 'notched trowel', and 'expansion joint'. This demonstrates your knowledge and can earn you extra marks.
Common Mistakes
Common errors to avoid in your coursework
- Misreading scale on drawings leading to incorrect material orders or cut tile sizes.
- Failing to check for and treat contaminants on walls (e.g., dust, grease) that impair adhesion.
- Using tiling adhesive outside its pot life or applying it in incorrect thickness.
- Not allowing for expansion joints or not starting tiling from the correct datum line, causing unsightly cuts.
- Overlooking the direction of tile pattern or grain, especially with stone or decorative tiles.
- Learners often fail to check that the substrate is load-bearing or suitable for the tile weight, leading to potential debonding or failure.
- A frequent error is not reading the tile orientation arrow or batch number, resulting in visible shading or pattern mismatch.
- Many students set out from an assumed level rather than establishing a true datum line, causing courses to run out of level and producing unsightly cuts.
- Using an adhesive that does not suit the tile material or environment (e.g., non-flexible adhesive on timber substrates) is a common cause of assessment failure.
- Inadequate cleaning of excess grout before it hardens leaves a cloudy residue on tiles, reducing the finish quality.
- Misconception: You can tile directly onto painted walls. Correction: Paint must be removed or keyed, and a suitable primer applied, otherwise the adhesive won't bond properly.
- Misconception: All tiles can be cut with a manual cutter. Correction: Porcelain and large-format tiles often require an electric wet saw for clean cuts; manual cutters are best for ceramic.
- Misconception: Grout is just for looks. Correction: Grout also prevents water ingress and debris buildup; proper mixing and application are essential to avoid cracking and staining.
