1. What is the Wall Paint Calculator?

The Wall Paint Calculator helps determine the amount of paint needed to cover a specific wall area based on the paint's coverage rate and number of coats required. This ensures you purchase the right amount of paint for your project.

2. How Does the Calculator Work?

The calculator uses the paint calculation formula:

\[ \text{Paint (litres)} = \frac{\text{Area (m²)}}{\text{Coverage Rate (m²/L)}} \times \text{Number of Coats} \]

Where:

  • \( A \) — Total wall area in square meters (m²)
  • \( C \) — Paint coverage rate in square meters per litre (m²/L)
  • \( N \) — 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 Accurate Paint Calculation

Details: Accurate paint calculation prevents wastage, saves money, and ensures consistent color coverage. It helps in proper project planning and budgeting.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: How do I measure wall area accurately?
A: Measure height and width of each wall, multiply them, and sum all wall areas. Subtract areas for windows and doors.

Q2: What is a typical paint coverage rate?
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 color consistency, but dark colors or porous surfaces may need more.

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.

Q5: Does surface texture affect coverage?
A: Yes, rough or textured surfaces require more paint than smooth surfaces due to increased surface area.
