He likens it to a car wrap. You can't expect to put vinyl on a rusty car and make it into a show car. The vinyl won't adhere to the rust. The same goes for any substrate. Rough wrap material is definitely a "niche product," says Heiob. "It is not something people have in their everyday inventory. They order it in as they need it as application requests come up." Most vehicle wraps employ PVC cast film. Rough films are PVC-free and ure- thane-based, he says. The film itself is white so that clients can digitally print their graphics onto the material using latex, solvent, eco-solvent and UV inks. Applying a laminate over the top protects the ink and increases the rigidity of the graphic so it is easier to install, he adds. Envision Print film LX/SV480mC was used for this brick exterior.

Cleveland's professional baseball field uses rough wrap decals behind its vari- ous concession stands. Schools use it as well to brand hallways, gymnasiums, locker rooms and stadiums with their messages or logos. Another customer of Mactac used rough wrap on light posts outside their building. Hospitals also use it to make patient areas more relaxed and people friendly. "Interest is growing only because it seems like, to me, the market is not so much about vehicle wraps anymore. It is about decorating space. Whether it is indoor or outdoor space and how you use the different products to create a space," he says. That could mean decorating a smooth wall on one side of a space and a rough wall on the other and include floors and windows. "With the move to architectural space design, interior design and exterior design space, we are seeing combinations of products including rough wrap stuff," he adds. Mactac also combines its rough wrap films with an overlaminate. Stadelman says he prefers a matte finished product rather than a glossy finish because it makes the decal look as if it were painted onto the brick or concrete. Some people prefer the gloss or luster finishes because they want it to stick out like a decal. Other customers put rough wrap on gloss tiles and then add a gloss overlaminate to make it match the sur- face of the adjacent tiles. 3 M's Place says he prefers a luster overlaminate because sometimes when applying rough surface wrap, banding can occur. That happens when it is put on with light or uneven pressure or there are speed variations. It can make the gloss level of the material higher from one pass to the other. By switching to a luster overlaminate, "your gloss level (Above left) Avery Dennison's Joey Heiob points out that the adhesive for rough surface wrap film has to be a little more aggressive than a standard removable adhesive, but it still needs to be removable.
