ABSTRACT:
A sprayer for applying an uncured grout to the interior surface of an enclosed wall includes a sprayer motor having a rotor rotatably mounted within the motor housing. A spray head is attached to the rotor and a spray conduit is adapted to introduce fluid grout under pressure to the spray head so that it will be thrown radially outwardly in a circular pattern. The motor and spray head are inserted into a conduit and actuated to throw the grout outwardly on to the interior walls of the elongated conduit.
