Maintain Consistent Brush Stroke Direction

What happens here

When applying paint with a brush, especially on vertical surfaces like door jambs, ensure all brush strokes run in the direction of the trim's grain. The painter demonstrates this by applying paint vertically on a door jamb. Using an angled sash brush can make cutting into corners and maintaining precise lines easier, offering more versatility in application.

Goal: Achieve a uniform, professional finish by aligning brush strokes with the trim's grain.
