1. What is the Paint Calculator Per Square Meter?

The Paint Calculator Per Square Meter helps determine the amount of paint needed for a painting project based on the surface area, paint coverage rate, and number of coats required. It ensures accurate paint estimation to avoid waste or shortage.

2. How Does the Calculator Work?

The calculator uses the paint formula:

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

Where:

  • \( A \) — Total surface area to be painted (square metres)
  • \( C \) — Paint coverage rate (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 is essential for budgeting, minimizing waste, ensuring project completion, and achieving consistent finish quality across all coated surfaces.

4. Using the Calculator

Tips: Measure the total surface area accurately, check the paint manufacturer's coverage rate specifications, and consider the required number of coats based on surface type and desired finish.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure surface area accurately?
A: Measure length and height of each surface, calculate area for each section, and sum them up. Don't forget to subtract areas for windows and doors.

Q2: What is a typical paint coverage rate?
A: Coverage rates vary by paint type but typically range from 10-15 square metres per litre for most interior paints. Always check the product specifications.

Q3: How many coats are usually needed?
A: Most projects require 2 coats for good coverage and durability. Dark colors over light may need 3 coats, while primer+2 coats is common for new surfaces.

Q4: Should I add extra paint for wastage?
A: Yes, it's recommended to add 10-15% extra to account for brush loading, spillage, touch-ups, and uneven surfaces.

Q5: Does surface texture affect paint consumption?
A: Yes, rough or textured surfaces can require 20-50% more paint than smooth surfaces due to increased surface area.
