How to Eliminate Tails and Streaks
Video shows what tails and streaks look like and talks through the solution for eliminating the problem while painting with an air assist spray gun.
Tails and streaks in the pattern indicate a pattern that is not fully atomized. This pattern can result in uneven coverage and poorly blended finishes.
Increasing the fluid pressure can improve this condition.
Increasing atomization air can also improve this condition, if increased fluid pressure is not desired.
Poor cleanliness of the air cap and tip can also produce tails and streaks in a pattern.
