🛠️ How It Works

Choose Interior for rooms or Exterior for outer façades.
Enter total area or room dimensions. Room mode automatically applies a 15% deduction for doors and windows.
Select the paint grade (Economy to Luxury).
Toggle Putty and Primer based on whether the wall is new or being repainted.
Review the labor cost based on current Nepal market regional rates.

📋 Real-Life Example

Example: Interior Painting for a 200 m² total surface area.
1. Total Area = 2,152 sq.ft.
2. Paint (Standard Emulsion) = 2,152 / 80 (sq.ft/L) ≈ 27 Litres.
3. Putty (2 coats) = 2,152 / 18 (sq.ft/kg) ≈ 120 kg.
4. Labor Cost (@ Rs. 12) = 2,152 * 12 = Rs. 25,824.

⚠️ Common Mistakes to Avoid

Failing to apply primer on new putty—this causes the paint to peel off quickly.
Assuming the same coverage for exterior as interior. Rough exterior plaster consumes 20-30% more paint.
