Dulux Paint Formula:
The Dulux Paint Calculation Formula estimates the amount of paint needed for a painting project based on area to be painted, paint coverage rate, and number of coats required. It helps ensure you purchase the right amount of paint for your project.
The calculator uses the Dulux paint formula:
Where:
Explanation: The formula calculates the paint needed by dividing the total area by the coverage rate per litre, then multiplying by the number of coats needed for complete coverage.
Details: Accurate paint calculation prevents wastage, saves money, and ensures you have enough paint to complete your project without interruptions. It also helps in proper project planning and budgeting.
Tips: Enter the total area in square metres, the paint coverage rate (typically found on paint can labels, usually 10-16 m²/L), and the number of coats needed. Always add 10-15% extra for wastage and touch-ups.
Q1: What is a typical paint coverage rate?
A: Most interior paints cover 10-16 m² per litre. Premium paints often have better coverage. Check the specific product label for accurate coverage rates.
Q2: How do I calculate wall area?
A: Measure height and width of each wall, multiply to get area, then add all wall areas together. Subtract areas for windows and doors.
Q3: How many coats are usually needed?
A: Most projects require 2 coats for good coverage. Dark colors over light may need 3 coats. New surfaces often need primer plus 2 top coats.
Q4: Should I buy extra paint?
A: Yes, always buy 10-15% extra for touch-ups and wastage. Keep leftover paint for future repairs.
Q5: Does surface texture affect coverage?
A: Yes, rough or textured surfaces require more paint than smooth surfaces. Porous surfaces may need primer first.
