Paint Calculation Formula:
The Dulux Decorator Centre 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. This helps ensure you purchase the correct amount of 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 helps avoid wastage, ensures you have enough paint to complete the project, and helps with budget planning. It's essential for both DIY projects and professional painting jobs.
Tips: Measure the total area accurately, check the paint can for coverage rate information, and consider the surface type when determining the number of coats needed. Always add 10-15% extra for wastage and touch-ups.
Q1: How do I measure the area accurately?
A: Measure the length and height of each wall, then multiply to get square metres. Subtract areas for windows and doors.
Q2: What is a typical coverage rate for paint?
A: Most paints cover 10-12 square metres per litre, but this varies by paint type and surface texture.
Q3: How many coats are usually needed?
A: Most projects require 2 coats for good coverage. Dark colors over light may need 3 coats.
Q4: Should I buy extra paint?
A: Yes, always buy 10-15% 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.
