What is the result of varying the application speed without changing flow volume?

Varying the application speed while keeping the flow volume unchanged can lead to uneven coverage of the area being treated. When the speed of the application changes, the rate at which the material is delivered to the target surface also changes relative to the area being covered. If the applicator moves faster, there is less time for the material to adequately cover the area, which might result in lighter application in some spots. Conversely, moving slower increases the amount of product delivered to that area, potentially leading to excessive amounts in those spots. This inconsistency can result in areas receiving too little treatment, while others could receive too much, ultimately affecting the overall effectiveness of the application. Therefore, uniformity in coverage is compromised when speed varies without adjusting the flow volume accordingly.
