Secure the Dam with Tape

What happens here

Once the 'dam' is formed, secure its lower edge to the wall using additional painter's tape. This prevents the paper from shifting or falling back against the wall, ensuring the dam remains effective during the spraying process. The presenter demonstrates tacking down the creased paper with a short piece of green painter's tape, holding the 'dam' in its outward-curled position.

Goal: Ensure the dam remains in position.
