Dulux Paint Coverage Formula:
The Dulux Paint Coverage Calculator helps determine the amount of paint needed for a painting project based on the area to be painted, the paint's coverage rate, and the number of coats required. This ensures you purchase the right amount of paint without waste or shortage.
The calculator uses the Dulux paint coverage 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 over-purchasing (saving money) and under-purchasing (avoiding color mismatch from different batches). It also ensures efficient project planning and reduces environmental waste.
Tips: Measure the total paintable area accurately. Check the paint can for the specific coverage rate (typically 10-16 m²/L). Consider surface porosity and preparation when determining coats needed.
Q1: What is a typical paint coverage rate?
A: Most quality paints cover 10-16 square metres per litre, but this varies by paint type, surface texture, and application method.
Q2: How do I calculate wall area?
A: Measure height and width of each wall, multiply to get area, then subtract windows and doors. Add ceiling area if painting ceilings.
Q3: Why do I need multiple coats?
A: Multiple coats ensure even color coverage, better durability, and complete hiding of the previous surface color.
Q4: Should I buy extra paint for touch-ups?
A: Yes, it's recommended to purchase 10-15% extra paint for touch-ups and future repairs.
Q5: Does surface type affect coverage?
A: Yes, porous surfaces like bare plaster or unpainted wood require more paint than previously painted smooth surfaces.
