Mask Repainted Trim Edges for Wall Painting

What happens here

Once the trim paint is fully dry and cured, carefully apply painter's tape along the newly created straight edges of the trim. Position the tape precisely to protect the clean trim lines from the upcoming wall paint. This masking process is vital for achieving perfectly straight lines when painting the walls, as it leverages the newly established, clean trim edge. Masking over previously crooked lines would be far more difficult and yield less precise results.

Goal: Prepare trim for wall painting by masking to achieve straight lines.
