What does flash time refer to?

• A. Time required to cure fully
• B. Time to wait before sanding
• C. Time allowed between coats for solvents to evaporate
• D. Time before paint starts to dry

Answer: (C)

Flash time is the waiting period after applying one coat before applying the next, allowing solvents in the film to evaporate. This helps prevent solvent entrapment, solvent popping, and adhesion problems, ensuring the next coat lays down smoothly. It’s not the curing time, nor simply the wait before sanding, nor a general “before it dries” window—the key purpose is enough solvent evaporation between coats, with the exact duration defined by the product and ambient conditions.
