Paint Calculation Formula:
The Dulux Paint Calculator is a specialized tool designed to help Australian homeowners and professionals accurately estimate the amount of paint needed for their painting projects. It calculates the required paint in litres based on surface area, paint coverage rate, and number of coats.
The calculator uses the standard paint calculation formula:
Where:
Explanation: The formula calculates the base paint requirement for one coat and multiplies it by the number of coats needed for complete coverage.
Details: Accurate paint calculation helps avoid wastage, ensures you purchase the right amount of paint, saves money, and prevents project delays due to insufficient materials. It's particularly important for large projects and when using premium paints.
Tips: Measure your surface area accurately in square metres. Check the paint can for the specific coverage rate (typically 10-16 m²/L for most Dulux paints). Consider adding 10% extra for wastage and touch-ups.
Q1: What is the typical coverage rate for Dulux paints in Australia?
A: Most Dulux interior paints cover 12-16 m²/L, while exterior paints typically cover 10-14 m²/L. Always check the specific product label.
Q2: How do I calculate wall area for painting?
A: Measure wall height and length, multiply to get area. Subtract windows and doors (approx. 2m² per window, 1.8m² per door).
Q3: Should I buy extra paint for touch-ups?
A: Yes, it's recommended to purchase 10% extra paint for future touch-ups and to account for wastage during application.
Q4: Does surface texture affect paint coverage?
A: Yes, rough or textured surfaces require more paint than smooth surfaces. Adjust your calculations accordingly.
Q5: How many coats are typically 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.
