Paint Calculation Formula:
The Dulux Trade Paint Calculator helps professionals and DIY enthusiasts accurately estimate the amount of paint required for a painting project. It calculates the litres of Dulux Trade paint needed 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 prevents wastage, ensures you purchase the right amount of paint, helps with budget planning, and avoids project delays due to insufficient materials.
Tips: Measure the total area accurately in square metres. Check the paint can for the specific coverage rate (typically 10-16 m²/litre for most paints). Consider applying an extra coat for better coverage on dark surfaces or when changing colors dramatically.
Q1: What is the typical coverage rate for Dulux Trade paint?
A: Most Dulux Trade paints cover 12-14 square metres per litre, but this varies by product type and surface texture.
Q2: Should I include windows and doors in my area calculation?
A: No, subtract the area of windows and doors from your total wall area for accurate calculation.
Q3: How many coats are typically needed?
A: Most projects require 2 coats for optimal coverage and finish. Three coats may be needed for dramatic color changes or porous surfaces.
Q4: Does surface texture affect paint coverage?
A: Yes, rough or textured surfaces require more paint than smooth surfaces. Adjust your coverage rate accordingly.
Q5: Should I buy extra paint for touch-ups?
A: It's recommended to purchase 10-15% extra paint for touch-ups and future maintenance.
