Deposition of sealant or similar materials

An applicator 1 is provided for the deposition of sealant onto a surface of a workpiece, the applicator comprising at least one inlet 2, 3, 4 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. There is at least one sealant-contacting surface 5, 6, 7 for contacting sealant deposited onto the surface through the inlet as the applicator is moved across the surface, thereby forming a film of sealant on the surface. There is at least one spacer 8a, b, c, 9a, b, c for contacting a surface onto which sealant is to be deposited and for maintaining the sealant-contacting surface in spaced relationship with the surface and at least one inlet reservoir 12, 13, 14 for receiving sealant from at least one inlet. The inlet reservoir is configured to provide a covered space when the applicator is in contact with a surface onto which sealant is to be deposited.
