Paint Formula:
The Dulux Decorating Centre Paint Calculator helps determine the exact amount of paint needed for your painting project. 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.
The calculator uses the paint calculation formula:
Where:
Explanation: The formula divides the total area by the paint's coverage rate to determine the paint needed for one coat, then multiplies by the number of coats to get the total requirement.
Details: Accurate paint calculation ensures you purchase the right amount of paint, avoiding wastage from over-purchasing or project delays from under-purchasing. It helps with budget planning and ensures consistent color throughout your project.
Tips: Measure the total wall/ceiling area accurately in square metres. Check the paint can for the specific coverage rate (typically 10-16 m² per litre). Consider applying an extra coat for dark color changes or porous surfaces.
Q1: How do I measure the area accurately?
A: Measure wall height and length, multiply to get area. Subtract windows and doors (approx. 2m² per window/door). For ceilings, measure length × width.
Q2: What is a typical coverage rate for Dulux paint?
A: Most Dulux paints cover 12-14 m² per litre, but check the specific product as coverage varies by paint type and surface.
Q3: How many coats are usually needed?
A: Most projects require 2 coats. Use 3 coats for dramatic color changes, painting over dark colors, or on porous surfaces.
Q4: Should I buy extra paint for touch-ups?
A: Yes, it's recommended to buy 10% extra for touch-ups and future repairs. Keep leftover paint properly sealed for future use.
Q5: Does this calculator account for different surface types?
A: The calculator provides a general estimate. Rough or porous surfaces may require more paint, while smooth surfaces may require less.
