Apply Masking Paper and Tape

What happens here

Using a hand masker loaded with Frog Tape and masking paper, apply a protective barrier along the edge of the door jamb. The masking tool simultaneously dispenses the green painter's tape and attaches the masking paper to it, creating a clean, straight line on the wall adjacent to the door jamb. Extend the masking paper the full length of the door jamb to cover the wall area that needs protection from overspray.

Goal: Protect the wall adjacent to the door jamb from paint.
