An expandable tray that includes a sheet having a first edge, a second edge opposite the first edge, a first end, and a second end 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 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 is movable to an expanded position to form a container defining a volume. The disclosure also features a method for protecting a surface using the expandable tray.
