Paint tray and attachments and a method of using the same

A coatings tray adapted to be used in a vertical orientation with a roller-type coating applicator, comprising a front wall, back wall, oppositely disposed side walls and a bottom wall cooperating to define a coating receptacle, with the front wall, back wall, and side walls each having a top edge cooperating to define an open top of the coating receptacle, a floor stand attachment selectively secured to the back wall so as to raise the top edge of the back wall when the coatings tray is supported on a generally flat, horizontal surface, and a generally L-shaped bracket extending from the back wall proximate the top edge thereof, the bracket comprising a relatively short first leg extending outwardly from the back wall and a relatively longer second leg extending from the first leg in a direction generally parallel to the back wall, wherein the floor stand attachment is selectively secured to the back wall via the generally L-shaped bracket.
