1. What is the Paint Per Square Meter Calculator?

The Paint Per Square Meter Calculator helps determine the amount of paint needed for a painting project based on the area to be painted, the paint's coverage rate, and the number of coats required.

2. How Does the Calculator Work?

The calculator uses the paint calculation formula:

\[ Paint (litres) = \frac{A}{C} \times N \]

Where:

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

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

3. Importance of Paint Calculation

Details: Accurate paint calculation helps avoid wastage, ensures you purchase the right amount of paint, and helps with budget planning for painting projects.

4. Using the Calculator

Tips: Measure the total area accurately, check the paint can for coverage rate information, and consider the surface type when determining the number of coats needed.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure the area accurately?
A: Measure length and height of each wall, multiply to get area, and subtract areas of windows and doors for accurate calculations.

Q2: What is a typical coverage rate for paint?
A: Most paints cover 10-12 square metres 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 good coverage, but dark colors over light may need 3 coats, while primer+painting may require separate calculations.

Q4: Should I buy extra paint?
A: It's recommended to buy 10-15% extra paint for touch-ups, wastage, and future repairs.

Q5: Does surface texture affect coverage?
A: Yes, rough or porous surfaces require more paint than smooth surfaces for the same area.
