In this series of works Mercado does not fragment the materials, as he has done in previous works, but modifies the very nature of the object, taking one characteristic of the object and replacing it with another. In this series of works he uses one of the most widely used materials in the history of art, the canvas. Using its skin as a metaphor, he has played with eliminating characteristics and reconstructing with others. Thus, the material of the canvas itself, the canvas, is replaced in some cases by other materials such as cement or resin. In other cases it is not the material but the way it is deformed and folded, returning once again to the metaphor of the skin. In this way, the rigid canvas folds or contracts as if it were another material. Or it is the layer of paint itself, torn from the canvas, that detaches from the support in the manner of a pictorial flaying.
