Mathematical Formula
Paint Liters = Total Wall Area × Number of Coats / Coverage Rate per Liter
Overview & Explanation
Calculates exact liters of interior/exterior paint, primer, and wall putty for any room or building facade.
How It Works
- Deducts openings (doors/windows) from gross wall area.
- Multiplies net area by 2 coats and applies coverage constants.
Practical Applications
- Room repainting
- New house painting budget
- Exterior weather coat estimation
Worked Example: 5m x 4m x 3m Room
Calculate paint for 2 coats.
1
Gross Wall Area
2 × (5 + 4) × 3
= 54 sq m
2
Paint Liters
(54 × 2) / 11
= 10 Liters
Frequently Asked Questions
How much area does 1 liter of wall paint cover?
1 liter of emulsion paint covers approximately 10 to 12 sq meters (100 to 120 sq ft) for a single coat.
