What is a common consequence of applying coatings incorrectly?

Applying coatings incorrectly often leads to a reduced longevity of the coating. This is due to various factors that can compromise the integrity of the application process. For instance, if the surface is not properly prepared, contaminants can interfere with adhesion, causing the coating to delaminate or wear away more quickly. Furthermore, incorrect mixing ratios of components or application in unsuitable environmental conditions like humidity and temperature can lead to defects such as bubbling, peeling, or improper curing. These issues diminish the protective and aesthetic qualities of the coating, ultimately resulting in a shorter lifespan than anticipated.

The other options do not accurately reflect the typical outcomes of improper coating application. While improved adhesion and increased application speed might sound favorable, they usually do not occur in cases of incorrect application. No change in performance is also unlikely, as improper techniques almost always produce a noticeable negative impact on coating performance. Hence, it is crucial to follow proper procedures to ensure longevity and effectiveness.
