1. What is the Paint Calculator?

The Paint Calculator estimates the amount of paint required to cover a given area based on the paint's coverage rate and number of coats needed. It helps in planning painting projects and purchasing the right amount of paint.

2. How Does the Calculator Work?

The calculator uses the paint calculation formula:

Where:

• \( A \) — Total area to be painted (square meters)
• \( C \) — Coverage rate of the paint (square meters per litre)
• \( N \) — Number of coats required

Explanation: The formula calculates the total paint volume needed by dividing the area by the paint's coverage rate and multiplying by the number of coats.

3. Importance of Paint Calculation

Details: Accurate paint calculation prevents wastage, ensures you have enough paint for the entire project, and helps with budget planning. Underestimating can lead to project delays, while overestimating wastes money.

4. Using the Calculator

Tips: Measure the total area accurately, check the paint can for coverage specifications, and consider applying a primer coat if needed. Always add 10-15% extra for touch-ups and wastage.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure the area accurately?
A: Measure length and height of each wall, calculate area (length × height), and sum all areas. Subtract areas for windows and doors.

Q2: What is a typical coverage rate for paint?
A: Most paints cover 10-12 m² per litre, but this varies by paint type, surface texture, and application method.

Q3: How many coats are usually needed?
A: Most projects require 2 coats for even coverage and durability. Dark colors over light may need 3 coats.

Q4: Should I buy extra paint?
A: Yes, purchase 10-15% extra for touch-ups and future repairs. Keep some for color matching.

Q5: Does surface type affect coverage?
A: Yes, rough surfaces absorb more paint. Primed surfaces require less paint than bare surfaces.
