ABSTRACT:
A device for use in applying a thin resinous coating to existing surfaces, such as concrete highways, to resurface and restore the same and improve their physical properties, such as skid resistance comprising two parallel supporting beams, a screed box having a bottom, two sides and a front and back sides, the bottom of which is attached to the parallel beams and the screed box having an adjustable dispersing gate at the back adapted to dispensing a controlled amount of the resinous binder in the box, at least one rotatable screed brush adjustably attached between the two beams behind the screed box and being adapted to bringing the dispersed binder in contact with the surface and pushing out any air that may be trapped under the coating, at least two spaced levelling bars perpendicularly and adjustably attached between the beams and being adapted to spreading and levelling the binder passing under the brush, at least one of the levelling bars being adapted to applying downward pressure on the layer of binder applied to the surface.
