One of the most frequent issues is over-specification. Materials are selected based on perceived risk rather than actual exposure conditions.

This often leads to:

• Increased project costs
• Longer lead times
• Unnecessary material upgrades

A typical example is specifying marine plywood where exterior plywood would perform just as well. This distinction is explored in Marine Plywood vs Exterior Plywood: What Australian Builders Often Get Wrong.

On the East Coast, humidity, salt air and temperature variation all affect panel performance. Failing to account for these factors can result in swelling, delamination or finish failure.

This is particularly relevant in projects discussed in Designing for Durability on the Australian East Coast: Choosing Panels for Heat, Humidity and Salt Air.

Surface finishes often receive more attention than the substrate beneath them. However, substrate selection directly impacts durability, fixing strength and finish performance.

MDF, plywood and particleboard each behave differently, as outlined in MDF vs Plywood in Commercial Interiors: Cost, Performance and Compliance in Australia.

Material selection should consider how a product performs over time, not just at installation. Laminates and veneers, for example, have different maintenance requirements and lifecycles.

Bord’s laminate panels and timber veneer range are often used together to balance durability and design.

Avoiding these mistakes comes down to understanding how materials perform in real conditions. When specification decisions are based on environment, usage and lifecycle, outcomes improve across the board.
