An apparatus for spreading viscous pavement sealant which comprises a means for carrying a quantity of the sealant, the carrying means having means for discharging a flow of the sealant onto the surface and means for controlling the rate of sealant flow. Further included are means pivotally mounted on the carrying means and resiliently biased against the surface for spreading a layer of the discharged sealant over the surface, and means pivotally mounted on the carrying means and resiliently biased against the surface for brushing the layer of sealant evenly over the surface. Means are provided for limiting the travel distance of the spreading and brushing means toward the surface. In one preferred embodiment, the apparatus is mounted on wheels and the discharging means include an auger driven by the wheels.
