An apparatus for spreading and leveling liquid surface coatings used to seal bituminous surfaces. The apparatus includes the combination of a mobile hopper assembly for storing and dispensing the viscous coating material at a controlled rate in the form of globules or droplets along the path of travel of the hopper. The globules or droplets are spread and smoothed into a thin continuous coating by means of a spreading and leveling attachment pivotally connected to and adapted to be towed behind the hopper. The spreading and leveling attachment has a frame that carries flexible resilient spreading and smoothing blades. The spreading blade is mounted on the frame closely spaced from the surface to be coated and is adapted to spread and flatten the globules and droplets on the surface in both longitudinal and lateral directions. The smoothing blade is mounted behind the spreading blade and is engageable with the surface to smooth the viscous liquid into a thin and continuous coating.
