Shield Exterior Corners

What happens here

When working around exterior corners, overspray can easily wrap around the corner and affect the adjacent wall surface. To prevent this, angle the cardboard shield to create a temporary barrier at the corner. This will ensure that the paint stays precisely on the intended wall section and does not 'kick out' or 'roll down' onto the perpendicular surface, maintaining sharp, clean edges.

Goal: Position the cardboard shield to effectively block overspray at exterior corners, preventing paint from extending onto adjacent walls.
