There are several methods to control the coating thickness of waterborne polyurethane:

1: Adjusting the viscosity of the coating: Adding water or thickeners to the coating can adjust its viscosity and thus change the thickness of the coating. The thicker the coating, the better the coating

Thick; The thinner the coating, the thinner the coating.

2: Control the number of brushing: The more brushing times, the thicker the coating. The number of brushing times can be controlled according to the required coating thickness.

3: Use appropriate tools: Different tools, such as brushes, rollers, or spray guns, can produce different coating thicknesses.
