ABSTRACT:
An apparatus for spreading a liquid over a surface, such as sealant over a pavement, is provided. The apparatus is mounted on a trailer and is comprised of a storage bin for containing the liquid to be spread, a drainage trough, and spreading brushes. Liquid is mixed in the storage bin and then transferred to the drainage trough where it is then dispersed onto the surface for spreading as the apparatus is towed along. The width of the path of dispersed liquid laid down by the drainage trough can be adjusted if necessary for sidewalks or other narrower surfaces. The brushes spread the liquid evenly over the surface. The drainage trough and brushes are hingedly connected to the storage bin and are pivotable between positions of operation and transport.
