1. What is the Bunnings Merbau Decking Calculator?

The Bunnings Merbau Decking Calculator helps estimate the number of merbau decking boards required for your decking project, accounting for material waste. Merbau is a popular hardwood choice known for its durability and rich color.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ N = \lceil \frac{\text{Deck Area}}{\text{Board Length} \times \text{Board Width}} \rceil \times (1 + \frac{\text{Waste Percentage}}{100}) \]

Where:

\( N \) — Number of boards needed
\( \text{Deck Area} \) — Total area to be decked (square meters)
\( \text{Board Length} \) — Length of individual decking board (meters)
\( \text{Board Width} \) — Width of individual decking board (meters)
\( \text{Waste Percentage} \) — Percentage of extra material needed for cuts and waste

Explanation: The formula calculates the base number of boards needed to cover the area, then adds a waste factor to account for cutting losses and errors.

3. Importance of Accurate Decking Calculation

Details: Proper calculation ensures you purchase enough materials for your project while minimizing waste and extra costs. Merbau decking is a premium product, so accurate estimation helps optimize your budget.

4. Using the Calculator

Tips: Measure your deck area accurately in square meters. Use the actual dimensions of the merbau decking boards you plan to purchase. Include a waste percentage (typically 10-15%) to account for cuts and mistakes.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical waste percentage for decking projects?
A: Most professionals recommend 10-15% waste factor for standard deck layouts. Complex designs may require 15-20%.

Q2: Why choose merbau decking?
A: Merbau offers excellent durability, natural resistance to decay and insects, and a beautiful reddish-brown appearance that ages well.

Q3: Should I account for board spacing in my calculations?
A: The calculator uses board face dimensions. For precise calculations, consider that installation spacing will slightly increase the actual coverage needed.

Q4: Can I use this calculator for other decking materials?
A: While designed for merbau, the formula works for any decking material where boards have consistent dimensions.

Q5: How do I measure irregularly shaped decks?
A: Break the area into regular shapes (rectangles, triangles), calculate each area separately, then sum them for the total deck area.
