Dulux Trade Paint Formula:
The Dulux Trade Paint Calculator estimates the amount of paint required for a painting project based on area, coverage rate, and number of coats. It helps professional painters and DIY enthusiasts accurately calculate paint quantities to avoid waste and ensure sufficient supply.
The calculator uses the Dulux Trade paint formula:
Where:
Explanation: The formula calculates the total paint volume needed by dividing the area by the paint's coverage rate and multiplying by the number of coats.
Details: Accurate paint calculation prevents over-purchasing (saving money) and under-purchasing (avoiding project delays). It ensures consistent color matching and optimal paint performance.
Tips: Measure the total paintable area accurately. Check the paint can for the specific coverage rate (typically 10-16 m²/litre for trade paints). Consider surface porosity and condition when determining coat requirements.
Q1: What is a typical coverage rate for Dulux Trade paints?
A: Most Dulux Trade emulsion paints cover 12-14 m² per litre, but always check the specific product datasheet.
Q2: Should I include windows and doors in the area calculation?
A: No, subtract the area of windows, doors, and other non-paintable surfaces from your total wall area.
Q3: How many coats are typically needed?
A: Most projects require 2 coats for optimal coverage and finish. Dark colors or dramatic color changes may need 3 coats.
Q4: Does surface texture affect coverage?
A: Yes, rough or porous surfaces require more paint. Textured walls may need 10-20% more paint than smooth surfaces.
Q5: Should I buy extra paint for touch-ups?
A: It's recommended to purchase 10% extra paint for touch-ups and future maintenance, especially for custom colors.
