Paint Formula:
The Dulux Paint Calculator helps determine the exact amount of paint needed for a painting project based on the surface area, paint coverage rate, and number of coats required. This ensures you purchase the right amount of paint without waste or shortage.
The calculator uses the paint 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 budgeting.
Tips: Measure the total surface area accurately. Check the paint can for the specific coverage rate (typically 10-16 m²/litre for most paints). Consider applying a primer coat for better results.
Q1: What is a typical coverage rate for Dulux paint?
A: Most Dulux paints cover 12-14 m² per litre, but always check the specific product label as coverage varies by paint type.
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 windows and doors.
Q3: Should I buy extra paint for touch-ups?
A: Yes, it's recommended to buy 10-15% extra paint for touch-ups and future repairs.
Q4: Does surface texture affect coverage?
A: Yes, rough or porous surfaces may require more paint. Textured walls typically need 10-20% more paint than smooth surfaces.
Q5: How many coats are usually needed?
A: Most projects require 2 coats for even coverage and color depth. Dark colors over light may need 3 coats.
