How easy is this to remove from the wall after its been placed there with the adhesive?

In general, murals are removed by using a sponge to wet the panels with water, and then the panels are able to be peeled from the wall. Once removed, there may be some adhesive residue left on the wall, but it can be washed off with soap and water. How easily it will come off depends on how well the wall was prepped prior to installing. Please let us know if you have any further questions.
