Paint Quantity:

1. What is the Dulux Paint Quantity Calculator?

The Dulux Paint Quantity Calculator estimates 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 helps prevent over-purchasing or running short of paint during your project.

2. How Does the Calculator Work?

The calculator uses the paint quantity formula:

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

Where:

\( \text{Area} \) — Total surface area to be painted (square metres)
\( \text{Coverage Rate} \) — Paint coverage capacity (square metres per litre)
\( \text{Number of Coats} \) — Desired number of paint coats

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 required for complete coverage.

3. Importance of Accurate Paint Calculation

Details: Accurate paint calculation ensures you purchase the right amount of paint, saving money by avoiding excess purchases and preventing project delays due to insufficient paint supply.

4. Using the Calculator

Tips: Measure the total area accurately, check the paint can for coverage specifications, and consider the surface type when determining the number of coats needed.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure the area accurately?
A: Measure length and height of walls, calculate area (length × height), and subtract windows and doors. For ceilings, measure length × width.

Q2: What is a typical coverage rate for Dulux paint?
A: Most Dulux paints cover 12-16 square metres per litre, but check the specific product label as coverage varies by paint type and surface.

Q3: How many coats are usually needed?
A: Most projects require 2 coats for optimal coverage and durability. Dark colors over light may need 3 coats, while light over dark may require a primer coat first.

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 texture affect paint coverage?
A: Yes, rough or textured surfaces require more paint than smooth surfaces. Adjust your calculations accordingly.
