- Ceiling
work (false ceiling/painting)
- Door
shutter hanging and joinery installation
- Wall
tiling (kitchen/toilet dados)

2. What are the critical quality checkpoints for tile
installation?
Answer: The 7 Critical Checkpoints:
- Substrate
Check: Surface should be clean, level (±3mm in 2m), and properly cured
- Material
Quality: Tiles should be same batch, no cracks, uniform thickness
- Adhesive
Mix: Correct water-cement ratio, proper consistency (no lumps)
- Installation:
Level tolerance ±2mm in 2m, joint width 2-3mm consistent
- Hollow
Sound Test: Tap test should not produce hollow sounds (indicates poor
bonding)
- Grouting:
Complete filling, uniform color, cleaned immediately after application
- Final
Inspection: Check alignment, level, joint consistency, surface
cleanliness
Memory Tip: "SMILE-HG" - Substrate, Material,
Installation, Level, Electrical (hollow test), Grouting
3. How do you calculate material requirements and wastage
for different finishing trades?
Answer: Standard calculation formulas:
Tiles/Flooring:
- Area
calculation: Length × Width
- Add
5-10% wastage for rectangular tiles
- Add
10-15% wastage for diagonal laying
- Add
15-20% wastage for complex patterns
Paint:
- Coverage:
120-140 sqft per liter (theoretical)
- Actual
coverage: 100-120 sqft per liter
- Coats
required: Primer + 2 finish coats
- Formula:
(Total Area × No. of Coats) ÷ Coverage Rate + 10% wastage
Plaster:
- 12mm
thickness: 0.012 cum per sqm
- Cement:
1 bag per 4-5 sqm (12mm thick)
- Sand:
1.5 times cement quantity
Quick Reference: Tiles 10%, Paint 10%, Plaster 5%,
Electrical 5%, Plumbing 15%
4. What are the mandatory tests required before finishing
work handover?

5. How do you handle substrate moisture issues before
applying finishes?
Answer: Moisture Management Protocol:
Detection:
- Use
