Spraying apparatus and method for using same

A spraying apparatus for applying liquid to a surface, comprising:

• a frame;
• a dome-shaped hood, comprising:
• a first portion supported by the frame in a closed position and directly coupled to the frame via a first hinge having a first substantially horizontal geometric axis, the first portion having a top side facing generally upwards and an underside facing generally downwards while the first portion is in the closed position, the first portion movable relative to the frame from the closed position substantially parallel to a surface to an open position about the first substantially horizontal geometric axis;
• at least one second portion coupled to the first portion via a second hinge having a second substantially horizontal geometric axis substantially perpendicular to the first substantially horizontal geometric axis while the first portion is in the closed position, the at least one second portion movable from a first position substantially parallel to the first portion to a second position about the second substantially horizontal geometric axis;
• and
• one or more holes configured to allow passage of at least one fluid conduit through the hood;
• and
• one or more spray heads, each spray head coupled to the underside of the hood substantially proximate to a respective one of the one or more holes and configured to spray a liquid on the surface, the one or more spray heads and the dome-shaped hood configured such that the dome-shaped hood provides a wind barrier for the liquid sprayed from the one or more spray heads;
• and
• a liquid tank fluidicly coupled to the one or more spray heads via the at least one fluid conduit and configured to hold the liquid.

• at least one second portion coupled to the first portion via a second hinge having a second substantially horizontal axis disposed at an angle to the first substantially horizontal axis while the first portion is in the first portion first position, the at least one second portion movable about the second substantially horizontal axis from a second portion first position in substantially planar alignment to the first portion to a second portion second position;
• and
• one or more spray heads, each spray head coupled to the underside of the hood and configured to spray a liquid on the surface, the one or more spray heads and the hood configured such that the hood provides a wind barrier for the liquid sprayed from the one or more spray heads.

• a frame;
• a hood, comprising:
• a first portion supported by the frame in a first position and directly coupled to the frame via a first hinge having a first axis, the first portion having a first side facing generally away from the surface and a second side facing generally toward the surface while the first portion is in the first position, the first portion pivotable relative to the frame about the first axis from the first position substantially parallel to the surface to a second position;
• at least one second portion pivotally coupled to the first portion via a second hinge having a second axis substantially non-parallel to the first axis while the first portion is in the first position;
• and
• one or more spray heads, each spray head coupled to the underside of the hood and configured to spray a liquid on the surface.
