What is a consequence of not allowing enough flash time between coats?

Not allowing enough flash time between coats can lead to checking and cracking in the paint finish. Flash time is the period required for solvents in the first coat to evaporate adequately before applying a subsequent coat. When this step is rushed, the solvents trapped beneath the second coat may expand and push against the newly applied layer, leading to surface tension issues. This can result in a finish that develops cracks or checking over time as the paint fails to adhere properly to the underlying layer.

The process of layering paint is sensitive, and if the first coat isn't adequately dried or cured before the next layer is added, it can compromise the structural integrity of the finish. This is especially important when using certain types of paints or clearcoats that rely on specific curing times to achieve their intended properties. Inadequate flash times can eventually lead to more pronounced defects in the finish, affecting both the aesthetics and long-term durability of the painted surface.
