(54) Surfacing device


(57) A surfacing device for trailing application of a fluid material to a surface comprises a bar comprising a leading side wall and a trailing side wall and a cavity therebetween for holding the fluid material, and an underside having an aperture therein, and a plate which, in a first position, closes the aperture and which is downwardly movable to a second position in which the aperture is open and a further aperture is defined between the plate and the trailing side wall, such that in use the fluid material exits the device through said further aperture. The device finds particular application in the surface dressing of roads and pavements, and reduces the airborne contamination and clogging associated with conventional surface dressing spray bars.
