Estimating the quantities and coverage areas of wall putty, primer, and paint is essential for efficient planning and budgeting in any painting project. Here's a comprehensive guide to help you determine the materials needed for a 2,000 sq ft area:

1. Wall Putty

• Coverage: Approximately 12-15 sq ft per kg for two coats.

• Calculation:

• For 2,000 sq ft:

  • Minimum: 2,000 sq ft ÷ 15 sq ft/kg 133 kg
  • Maximum: 2,000 sq ft ÷ 12 sq ft/kg 167 kg

• Bags Required:

• Assuming 40 kg per bag:

  • Minimum: 133 kg ÷ 40 kg/bag 3.33 bags
  • Maximum: 167 kg ÷ 40 kg/bag 4.18 bags

• Cost Estimate:

• If one bag costs800:

  • Minimum: 4 bags ×800 =3,200
  • Maximum: 5 bags ×800 =4,000

• Labor Cost:

• Approximately3 per sq ft for two coats.

• Total: 2,000 sq ft ×3 =6,000

• Total Putty Application Cost:

• Minimum:3,200 (material) +6,000 (labor) =9,200
• Maximum:4,000 (material) +6,000 (labor) =10,000

2. Primer

• Coverage: Approximately 120-140 sq ft per liter for one coat.

• Calculation:

• For 2,000 sq ft:

  • Minimum: 2,000 sq ft ÷ 140 sq ft/liter 14.3 liters
  • Maximum: 2,000 sq ft ÷ 120 sq ft/liter 16.7 liters

• Cost Estimate:

• If one liter costs200:

  • Minimum: 15 liters ×200 =3,000
  • Maximum: 17 liters ×200 =3,400

• Labor Cost:

• Approximately2 per sq ft for one coat.

• Total: 2,000 sq ft ×2 =4,000

• Total Primer Application Cost:

• Minimum:3,000 (material) +4,000 (labor) =7,000
• Maximum:3,400 (material) +4,000 (labor) =7,400

3. Paint

• Coverage: Approximately 100-120 sq ft per liter for one coat.

• Calculation:

• For two coats over 2,000 sq ft:

  • Total Area: 2,000 sq ft × 2 = 4,000 sq ft
  • Minimum: 4,000 sq ft ÷ 120 sq ft/liter 33.3 liters
  • Maximum: 4,000 sq ft ÷ 100 sq ft/liter 40 liters

• Cost Estimate:

• If one liter costs300:

  • Minimum: 34 liters ×300 =10,200
  • Maximum: 40 liters ×300 =12,000

• Labor Cost:

• Approximately6 per sq ft for two coats.

• Total: 2,000 sq ft ×6 =12,000

• Total Paint Application Cost:

• Minimum:10,200 (material) +12,000 (labor) =22,200
• Maximum:12,000 (material) +12,000 (labor) =24,000

4. Summary

• Wall Putty:
• Material:3,200 -4,000
• Labor:6,000

• Total:9,200 -10,000

• Primer:

• Material:3,000 -3,400
• Labor:4,000

• Total:7,000 -7,400

• Paint:

• Material:10,200 -12,000
• Labor:12,000

• Total:22,200 -24,000

• Grand Total:

• Minimum:9,200 +7,000 +22,200 =38,400
