Mask the Lower Boundary and Floor

What happens here

Next, prepare the lower boundary and the flooring. Kneel down and apply green painter's tape along the base of the wall where it meets the floor. For efficiency, the painter uses a specialized tape and paper dispenser (like a 3M Hand-Masker) to simultaneously apply the tape and attach a continuous roll of brown masking paper. This paper is then extended across the floor, ensuring all adjacent flooring is completely covered and protected from paint drips or overspray. Additional pieces of tape can be used to further secure the paper if needed, especially in corners or along curves.

Goal: Protect the floor and base from overspray and drips.
