Paint Calculation Formula:
The Dulux Heritage Paint Calculator estimates the amount of paint needed for a painting project based on the area to be painted, the coverage rate of the paint, and the number of coats required. It helps ensure you purchase the correct amount of Dulux Heritage paint for your project.
The calculator uses the paint calculation formula:
Where:
Explanation: The formula calculates the total paint volume needed by dividing the area by the coverage rate and multiplying by the number of coats.
Details: Accurate paint calculation prevents wastage, ensures you have enough paint to complete the project, and helps with budget planning. Underestimating can lead to project delays, while overestimating results in unnecessary expense.
Tips: Measure the total area accurately, check the coverage rate specified on the paint can (typically 10-16 m²/litre for Dulux Heritage), and consider the surface porosity and color changes when determining the number of coats needed.
Q1: What is the typical coverage rate for Dulux Heritage paint?
A: Dulux Heritage typically covers 12-14 square metres per litre, but this can vary based on surface texture and application method.
Q2: How do I calculate the area to be painted?
A: For walls: (height × width) for each wall. Subtract window and door areas. For ceilings: length × width.
Q3: How many coats are usually needed?
A: Most projects require 2 coats for optimal coverage and finish. Dark colors over light may need 3 coats.
Q4: Should I add extra paint for wastage?
A: It's recommended to add 10-15% extra to account for wastage, spills, and touch-ups.
Q5: Does surface texture affect coverage?
A: Yes, rough or porous surfaces require more paint than smooth surfaces. Always test on a small area first.
