1. What is the Dulux Paint Calculator?

The Dulux Paint Calculator helps homeowners and professionals in New Zealand accurately estimate the amount of paint needed for painting projects. It calculates the required paint in litres 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 Dulux paint 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 divides the total area by the paint's coverage rate to determine the paint needed per coat, then multiplies by the number of coats for the total requirement.

3. Importance of Accurate Paint Calculation

Details: Accurate paint calculation prevents wastage, saves money, and ensures you have enough paint to complete your project without interruptions. It's essential for budgeting and project planning.

4. Using the Calculator

Tips: Measure the total area accurately in square metres. Check the paint can for the specific coverage rate (typically 10-16 m²/L). Consider adding 10% extra for wastage and touch-ups.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical coverage rate for Dulux paint?
A: Most Dulux paints cover 10-16 m² per litre, but always check the specific product's coverage rate on the can.

Q2: How do I calculate the area of a room?
A: For walls: (Length + Width) × 2 × Height. For ceilings: Length × Width. Subtract areas of windows and doors.

Q3: How many coats are usually needed?
A: Most projects require 2 coats for good coverage. Dark colors over light may need 3 coats, while light over dark may require a primer coat first.

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

Q5: Does surface texture affect coverage?
A: Yes, rough or textured surfaces require more paint than smooth surfaces. Adjust your calculations accordingly.
