I very successfully Miracle-Mucked a 44" wide by 90" tall coated canvas to a matte-painted wallboard surface. Was very easy, we taped up the edge of the rolled-on-a-tube print at the top in registration, coated the wall quick-like-a-bunny (two people trying to stay inside the masking tape marks), rolled down the canvas, and patted it down with cotton gloved hands. Wiped off the small amount of glue that got onto the print surface with wet towels (the canvas had better be coated for this kind of treatment). Didn't have to deal with the excess glue at the sides which was later covered up with some Home Depot moulding. It's still up and looking great 3 years later, fully a year past my promised lifetime. No apparent problems whatsoever. But would not care to do this with concrete, gloss painted walls, rough surfaces etc.
Should add that the wall was a temporary interior wall, so all thoughts of removing the print were irrelevant which is truly fortunate. However, it is theoretically possible to re-active Muck with a heat gun and peel off the print while hot. You need about 160F, I believe. I tried one removal experiment with a Gator-mounted canvas and recovered the print without damage (except for an almost invisible layer of Muck), although the Gator wound up with a slight permanent warp.
