Common Mistakes
Common errors to avoid in your coursework
- Overlooking the need to check and prepare substrate flatness and stability before tiling, leading to adhesion failure or lipping
- Using incorrect adhesive or grout for specific tile materials, substrates, or service conditions, causing debonding or staining
- Neglecting to protect finished surfaces and adjacent areas, resulting in damage that necessitates costly rework or cleaning
- Misinterpreting setting out or failing to establish accurate datum lines, causing uneven cuts, misalignment, or poor visual symmetry
- Failing to check substrate suitability before tiling, leading to adhesion failures or uneven surfaces.
- Using incorrect adhesive or grout for the tile type or environment (e.g., not using flexible adhesive for underfloor heating or waterproof grout for wet areas).
- Neglecting to allow for movement joints or expansion gaps, causing tiles to crack or debond over time.
- Poor cutting techniques resulting in inaccurately cut tiles and excessive waste.
- Inadequate cleaning of surplus adhesive or grout, leaving stains or uneven surfaces.
- Not wearing appropriate personal protective equipment (PPE) such as safety glasses, gloves, and knee pads, leading to avoidable injuries.
- Failing to check substrate flatness before tiling, leading to lippage.
- Not allowing for movement joints when tiling large floor areas, causing cracking.
- Using an incorrect notched trowel size for the tile type, resulting in poor adhesion.
- Misconception: Tiling directly onto painted surfaces is acceptable. Correction: Paint must be removed or keyed, and the surface primed, otherwise adhesion will fail.
- Misconception: All adhesives are the same. Correction: Different adhesives are designed for specific tiles (e.g., porcelain, natural stone) and conditions (e.g., wet areas, underfloor heating).
- Misconception: Movement joints are only needed in large areas. Correction: Movement joints are required at perimeters and at intervals specified by standards, regardless of area size, to prevent stress fractures.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A bathroom wall measures 3.2m in length and 2.4m in height. The wall has a window opening of 0.9m × 1.2m. Tiles are 300mm × 600mm. Calculate the number of tiles needed, including 10% wastage.
- 1.Step 1: Calculate the total wall area: 3.2m × 2.4m = 7.68m².
- 2.Step 2: Subtract the window area: 0.9m × 1.2m = 1.08m², so net area = 7.68 - 1.08 = 6.6m².
- 3.Step 3: Add 10% wastage: 6.6 × 1.10 = 7.26m².
- 4.Step 4: Calculate tile area: 0.3m × 0.6m = 0.18m².
- 5.Step 5: Divide total area by tile area: 7.26 ÷ 0.18 = 40.33, so round up to 41 tiles.
Question: Describe the correct procedure for tiling a floor with large-format porcelain tiles (600×600mm) onto a concrete screed, including movement joints.
- 1.Step 1: Ensure the screed is fully cured (at least 28 days), dry, and level. Check for cracks and repair if necessary.
- 2.Step 2: Prime the surface with a suitable primer to control suction and improve adhesion.
- 3.Step 3: Lay out tiles to plan the layout, avoiding small cuts at edges. Use spacers to maintain consistent joint widths.
- 4.Step 4: Apply a suitable adhesive (e.g., cement-based or flexible) using a notched trowel, ensuring full coverage (at least 90% for floors).
- 5.Step 5: Fix the tiles, pressing firmly and using a levelling system to ensure a flat surface. Allow adhesive to cure.
- 6.Step 6: Install movement joints around the perimeter and at intervals (e.g., every 8-10m²) as per manufacturer's guidance, using a suitable sealant.
