Apply Gray/Brown Wood Stain

What happens here

The video transitions to demonstrate the application of a different color stain, a gray/brown hue. This implies the machine was either cleaned between stain types or is a separate setup. The gray/brown stain is poured into the machine's reservoir. The operator is also shown stirring a bucket of the gray/brown stain to ensure it is thoroughly mixed and has a consistent color and viscosity before being loaded into the machine. Wooden planks are then fed through the machine, receiving the uniform gray/brown coating from the rollers. Excess stain is seen being collected into a bucket below the machine.
