A stand for supporting a hopper for applying joint compound to a drywall corner bead has first and second pairs of legs which cross over and are pivoted together at their crossover point in a scissors-like manner. Each pair of legs has a cross bar extending between its upper ends, and spaced connecting straps extend transversely between the cross bars in the deployed position of the stand, the connecting straps being of predetermined length to control the maximum spacing between the cross bars. Each connecting strap is slidably engaged with the respective cross bars for movement along the cross bars. A hopper is seated on top of the cross bars with a reduced length lower portion of the base extending downwardly between the cross bars. The two connecting straps are moved into engagement with opposite sides of the hopper base in order to support the hopper.
