Mask an Inside Corner

Masking A Ceiling Hacks. Using A Hand Masker Upside Down.
What happens here
To address an inside corner, the painter modifies the application technique. He uses the masking machine to apply the tape and paper up to the corner. At the corner, he carefully cuts the masking paper, allowing for flexibility. He then manipulates the tape and paper around the corner, ensuring it adheres tightly to both ceiling surfaces. Any excess or overlapping paper is pressed down firmly, and additional short strips of masking tape are used to secure the folds and edges, creating a continuous and neat seal around the corner. This prevents paint from seeping onto the ceiling in the corner area.
Goal: Effectively mask an inside corner to prevent paint from reaching the ceiling.
