Wall Paint Calculator M2

Paint Formula:

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

Paint Needed:

1. What is the Wall Paint Calculator?

The Wall Paint Calculator helps determine the amount of paint needed for a painting project based on wall area, paint coverage rate, and number of coats required. It ensures you purchase the right amount of paint without excess or shortage.

2. How Does the Calculator Work?

The calculator uses the paint formula:

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

Where:

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

Details: Proper paint calculation prevents wastage, saves money, ensures consistent color across all coats, and helps plan the project efficiently.

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 calculate wall area?
A: Measure height and width of each wall, multiply to get area, 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 good coverage. Dark colors or dramatic color changes may need 3 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.

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