Paint Coverage Calculator Dulux

Paint Coverage Formula:

\[ \text{Paint (litres)} = \frac{A}{C} \times N \]

1. What is the Paint Coverage Calculator?

The 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 excess or shortage.

2. How Does the Calculator Work?

The calculator uses the paint coverage formula:

\[ \text{Paint (litres)} = \frac{\text{Area (m²)}}{\text{Coverage Rate (m²/litre)}} \times \text{Number of Coats} \]

Where:

Area (A) — Total surface area to be painted in square metres
Coverage Rate (C) — Paint coverage capacity in square metres per litre
Number of Coats (N) — How many layers of paint will be applied

Explanation: The formula calculates the total paint volume needed by dividing the area by the coverage rate and multiplying by the number of coats required for complete coverage.

3. Importance of Accurate Paint Calculation

Details: Accurate paint calculation prevents wastage of materials and money, ensures consistent color quality across the project, and helps with proper project planning and budgeting.

4. Using the Calculator

Tips: Measure the total area accurately, check the paint can for the specific coverage rate (typically 10-16 m²/litre for most paints), and consider the surface porosity when determining the number of coats needed.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical coverage rate for Dulux paint?
A: Most Dulux paints cover 12-16 m² per litre, but this varies by product type and surface texture. Always check the specific product label.

Q2: How do I calculate the area of irregular shapes?
A: Break irregular areas into regular shapes (rectangles, triangles), calculate each separately, and sum the totals for the complete area.

Q3: Should I include windows and doors in my area calculation?
A: For walls, you can subtract window and door areas, but for ceilings and floors, calculate the full area as these surfaces are continuous.

Q4: How many coats are typically needed?
A: Most projects require 2 coats for even coverage and color consistency. Dark colors or dramatic color changes may require 3 coats.

Q5: Does surface texture affect paint coverage?
A: Yes, rough or porous surfaces require more paint than smooth surfaces. Textured walls may need 10-20% more paint than calculated.
