Deposition of sealant or similar materials

An applicator for the deposition of sealant onto a surface of a workpiece, the applicator comprising:

• at least one inlet for depositing sealant on to a surface or a nozzle-receiving space for receiving a nozzle comprising at least one inlet for depositing sealant on to a surface;
• at least one sealant-contacting surface for contacting sealant deposited onto the surface through an inlet as the applicator is moved across said surface, thereby forming a film of sealant on said surface;
• at least one spacer for contacting a surface onto which sealant is to be deposited and for maintaining the sealant-contacting surface in spaced relationship with the surface;
• at least one inlet reservoir for receiving sealant from at least one inlet, the inlet reservoir being configured to provide a covered space when the applicator is in contact with a surface onto which sealant is to be deposited;
• at least one overflow outlet for the egress of excess sealant from an inlet reservoir;
• wherein the at least one overflow outlet is in fluid communication with an inlet reservoir;
• an overflow reservoir for receiving excess sealant from at least one overflow outlet;
• and,
• wherein the at least one overflow outlet is positioned above the overflow reservoir when the applicator is in an inverted orientation.
