In what position should the gun be held while creating a fillet seal?

The correct position for holding the gun while creating a fillet seal is a near vertical position because this orientation allows for better control and precision when applying the sealant. A near vertical angle helps to maintain a consistent bead of sealant, which is crucial for ensuring that the fillet seal adheres properly to both surfaces being joined. This position also facilitates gravity to assist with the material flow, enabling a smoother and more uniform application.

Holding the gun in a near vertical position allows the operator to easily view the work area and adjust their angle as needed to create an even fillet. It prevents excessive buildup of sealant in one area, which can occur if the gun is held too vertically or horizontally. Other positions, such as completely horizontal or vertical, could lead to challenges in achieving the correct bead shape and might contribute to waste or defects in the seal.
