What happens here

The old particle board flooring, and potentially multiple layers of linoleum, are removed to expose the original wood planks underneath. The worker attempts to pry off the top layer of flooring but encounters significant flaking, indicating poor adhesion that would compromise new tile installation. A circular saw is used to cut the particle board into smaller, more manageable sections, followed by a pry bar and hammer to remove them. The narrator discovers previous plumbing lines and multiple layers of flooring, indicating past renovations. This also generates significant dust, particularly from cutting particle board. It's critical to maintain existing dust containment barriers throughout this process. Once the particle board is removed, the original subfloor is visible, which will be prepared for new flooring.

Goal: Clear the floor down to the original subfloor for new tile installation.
