Paint Calculation Formula:
The Wall Paint Calculator helps estimate the amount of paint needed for wall painting projects in India. It calculates the required paint in litres based on wall area, paint coverage rate, and number of coats needed.
The calculator uses the paint calculation formula:
Where:
Explanation: The formula divides the total area by the coverage rate to get paint needed per coat, then multiplies by the number of coats for the total requirement.
Details: Accurate paint calculation helps avoid wastage, ensures you purchase the right amount, and helps with budget planning for painting projects in Indian homes and buildings.
Tips: Measure wall area accurately in square feet. Check the paint can for coverage rate (typically 80-120 sq ft/litre). Consider 2-3 coats for optimal coverage. All values must be positive numbers.
Q1: What is a typical coverage rate for paint in India?
A: Most paints cover 80-120 square feet per litre, but this varies by paint quality, surface texture, and application method.
Q2: How do I calculate wall area in square feet?
A: Measure length and height of each wall in feet, multiply to get area, then sum all wall areas. Subtract window and door areas.
Q3: How many coats are usually needed?
A: Most projects require 2 coats for even coverage. Dark colors over light may need 3 coats. New surfaces often need primer plus 2 coats.
Q4: Should I buy extra paint for touch-ups?
A: Yes, it's recommended to buy 10-15% extra paint for touch-ups and future repairs. Store properly for later use.
Q5: Does this work for ceiling paint calculation?
A: Yes, the same formula applies. Calculate ceiling area separately and add to total area if painting both walls and ceiling.
