What is the recommended maximum paint thickness that should be applied in one application?

The recommended maximum paint thickness for a single application is typically in the range of 4 to 6 mils. This thickness ensures that the paint adheres properly to the surface and cures appropriately without issues such as sagging or running. Applying paint within this range allows for adequate coverage while still enabling the solvents to evaporate effectively, promoting a smooth finish and optimal durability. Exceeding this thickness can lead to problems such as blistering, poor adhesion, and increased drying times, which can compromise the overall quality of the paint job.
