Digimura can be removed dry without causing damage to the wall surface (assuming that the wall surface is stable or has been made stable prior to application). You may find, however, that the non-woven backing splits as you take down the Digimura, and bits get left behind on the surface ... not a problem ... they can easily be removed by soaking them in warm water mixed with a mild household detergent and gently working the pesky puppies off the surface with a wallcovering stripping knife.
