Identify and Prepare Affected Subfloor

What happens here

The video starts by showing a subfloor with visible pet urine stains. The speaker emphasizes the strong unpleasant odor present in the room due to these stains. Before proceeding, ensure that any previous flooring (like carpet) has been completely removed to expose the subfloor. This allows for direct treatment of the contaminated wood or particleboard surface.

Goal: Begin by identifying areas of the subfloor that have been contaminated with pet urine after the removal of old carpeting or flooring. Note the presence of strong, lingering odors, which indicate the need for odor sealing.
