Marmoleum Sheet Flooring, such as Striato, must be glued down to a perfectly flat, clean, grade A plywood or concrete non-cush subfloor. Marmoleum sheet lacks the structural integrity to go over cushion as there is no wood material in it. If you want a degree of cushion topped with marmoleum, you could try Marmoleum Click Cinch Loc (which has a high density wood fiber core) over Quietwalk Plus.
