An expandable tray (100) that includes a sheet (130) having a first edge (230), a second edge (240) opposite the first edge, a first end (210), and a second end (220) opposite the first end, the ends being substantially transverse to the edges. The sheet includes a plurality of oppositely folded portions disposed between the first end and the second end forming a plurality of folds (140) extending from the first edge to the second edge, a first securement device for securing the folds in a stacked configuration near the first edge, and a second securement device for securing the folds in a stacked configuration near the second edge. The portion of the folds extending between the secured ends (110, 120) is movable to an expanded position to form a container defining a volume. The invention also features a method for protecting a surface using the expandable tray.
