What does the term "flash time" refer to in paint application?

The term "flash time" specifically refers to the duration needed between coats of paint for the solvents within the applied paint to evaporate adequately. This process is crucial in paint application as it ensures that the subsequent layer adheres properly to the existing layer without trapping solvents, which can lead to issues such as bubbling, wrinkles, or poor adhesion. Adequate flash time allows for a proper chemical bonding between layers, contributing to a smooth finish and the longevity of the paint job.

While other terms may seem similar, they highlight different stages or aspects of the paint application process. For instance, complete curing is a longer process that encompasses all chemical reactions until the paint reaches its maximum hardness, while drying to the touch indicates a superficial dryness that doesn’t necessarily imply readiness for another coat. The total time for a painting project includes all aspects of preparation, application, and drying, which goes beyond the specific focus of flash time.
