What happens here

While the rolling is underway, the masking person (Zach) proceeds to cover the windows, specifically the bay window and its blinds. Use brown paper and 1-inch 3M 2020 tape to protect the window frames, glass, and blinds from paint. Once the baseboards are masked, Zach begins cutting in around the baseboards, using a 3-inch angled sash brush and applying clear caulk along the top edge of the tape. This caulk seals the tape, preventing any paint from bleeding underneath and ensuring a sharp, clean line.

Goal: Protect windows from paint and create crisp baseboard edges.
