Understand Material Composition and Vulnerability

What happens here

The expert further details the composition of hardboard siding, explaining that it's essentially 'glorified cardboard' made from wood fibers glued together and then stamped with a paper texture to mimic the appearance of real wood. This explanation is crucial for understanding why traditional sanding methods are inappropriate for this material. He demonstrates this by showing how the material delaminates due to water damage.

Goal: Grasp the underlying structure and weaknesses of composite siding.
