Secure Side Edges with Tape

What happens here

After the top edge is secure, extend the plastic sheeting downwards to cover the entire window pane. Take a roll of blue painter's tape and apply it tightly along one vertical side of the window frame, overlapping the edge of the plastic sheeting onto the drywall. Ensure the tape is pressed down firmly to create a good seal. At the top corner, carefully tear the tape to form a sharp, clean angle. If the tape accidentally runs onto the drywall beyond the desired line, gently pull it back to the correct position. Repeat this exact process for the opposite vertical side of the window frame, ensuring both sides are taut and well-sealed.

Goal: Carefully apply painter's tape along both vertical sides of the window frame to secure the plastic sheeting and create sharp, clean corners.
