What happens if too much drier is added to the paint during application?

When too much drier is added to paint during application, it can lead to the formation of a brittle paint film. Dryers, which are chemical additives that accelerate the drying process, can cause the paint to cure too quickly if used in excess. This rapid drying can create tension within the paint film, making it less flexible and more susceptible to cracking and peeling over time.

In a properly formulated paint mixture, the right balance of drier helps achieve optimal drying times while maintaining the integrity of the paint film. However, exceeding the recommended amount can compromise the paint’s structural properties, leading to brittleness. This brittleness can result in various issues including poor adhesion to the substrate and loss of the protective qualities of the paint, ultimately leading to premature failure of the coating.
