S I G N & D I G I T A L G R A P H I C S • November 2018 • 55 R ough surface wraps have only improved with age thanks to the development of new materials and adhesives. It is easier than ever to cover a brick or concrete structure with remov- able graphics that look like they were painted on. 3 M devised its Envision Print film LX/ SV480mC about five years ago. The film is not PVC-based like most car wraps so it conforms to rough surfaces and retains the shape of the surface really well, says Nate Place, senior application engineer- ing technician at 3M. "It also has a high tensile strength, which is beneficial to keeping the film intact during removal rather than tearing into bits and pieces," he says. Improvements to the adhesive pack- age were made to allow for good adhe- sion and better release when it comes time to remove the film, he adds. Most rough wall applications are large, so it is essential that the entire process from application to removal be fast and clean. Rough surface wraps are great for architectural uses, both inside and out- side, in any place that used to have to use hard signage or banners. Wayfinding applications are another great use for rough surface wraps, eliminating the need for fixtures to anchor traditional hard signage, he says. That makes it easier for buildings to change hands or design quickly.

Avery Dennison launched its first rough and textured wall film in April of this year. MPI 1405 Easy Apply RS is urethane-based, which makes it highly durable and highly conformable, says Joey Heiob, technical service represen- tative at Avery Dennison. "When you are trying to apply it to brick textures or stucco textures or bare contact, you want something that will conform to the peaks and valleys," Heiob says. "A film must not only conform but stay in there." Avery Dennison pairs its rough wall film with a urethane clear laminate which helps it with conformability and durabil- ity to weather the elements. "We are seeing an increase in facade graphics from an architectural stand- point. We are seeing more people utilize old building spaces with graphics of some sort, urban art or actually P.O.P.-type sig- nage," he says. "We are definitely seeing more people wanting to use the facades of their buildings to apply graphics to." Arenas and stadiums are big users of rough wall wraps. With the demand has come a need for better adhesives. Heiob points out that the adhesive has to be a little more aggressive than a standard removable adhesive but it still needs to be remov- able. In Avery Dennison's case, a heat source is used to soften the film again so it is easy to remove from the substrate, just like what is used in the vehicle wrap industry. Most users of rough wall wraps are not expecting the graphics to be long- term. They want to be able to remove them quickly and with minimal adhesive residue left behind. Even though rough wraps adhere to rough surfaces, he says that the substrate, whether it is brick or Wrapped images over cinder blocks for Stan's Donuts and Coffee. (Images courtesy of Mactac)
