Initiate Vertical Paint Application

What happens here

Begin the actual painting process by placing the loaded pressure roller at the top of the wall, typically near the ceiling line. Apply light, even pressure, and draw the roller straight downwards to the baseboard. Immediately after completing the downward stroke, move the roller slightly to the side (horizontally) and roll it back upwards to the ceiling. This initial up-and-down motion establishes the first painted strip on the wall, demonstrating the effective and continuous paint feed from the airless sprayer without the need to dip the roller.

Goal: Apply the initial strip of paint using vertical strokes.
