1. What is the Merbau Decking Calculator?

The Merbau Decking Calculator helps estimate the number of decking boards required for your project, specifically for Merbau timber available at Bunnings. It accounts for deck area, board dimensions, and includes a waste factor for cuts and errors.

2. How Does the Calculator Work?

The calculator uses the 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 (m²)
\( \text{Board Length} \) — Length of individual board (m)
\( \text{Board Width} \) — Width of individual board (m)
\( \text{Waste Percentage} \) — Additional percentage for waste and cuts (%)

Explanation: The formula calculates the minimum number of boards needed to cover the deck area, then adds a percentage for waste, cuts, and potential errors during installation.

3. Importance of Accurate Decking Calculation

Details: Proper calculation ensures you purchase the right amount of materials, minimizing waste and avoiding project delays due to insufficient materials. Merbau decking is a premium product, so accurate estimation helps control costs.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the 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: Are Merbau boards standard sizes at Bunnings?
A: Bunnings typically stocks Merbau decking in standard sizes, but always verify current available dimensions at your local store.

Q3: Should I consider board spacing in my calculations?
A: This calculator assumes tight butt joints. For spaced boards, you may need to add 2-5% additional material.

Q4: Does this account for pattern variations?
A: For complex patterns like herringbone, increase your waste percentage to 20-25% to account for additional cuts.

Q5: Can I use this for other timber types?
A: While designed for Merbau, this calculator works for any decking material where you know the board dimensions.
