50 • March 2019 • S I G N & D I G I T A L G R A P H I C S WRAPS DIGITAL GRAPHICS such as Avery Dennison MPI 2600, or a matte or gloss film, you will need to make a proper film selection. Also, a textured wall will require a film that can adhere to a textured surface, like MPI 1405. This film rolls out over brick, cinderblock and other tough materials." What are some of the best applications to start with? Matt Braswell, Technical Sales Specialist for Arlon Graphics, says for beginners, smooth interior wall application is the best place to start. "Start with smaller pieces (spot and partial wall decals) and work your way onto larger pieces (full wrap) as you grow in experi- ence and confidence." He notes to use painter's tape for registration marks and hinging. "With full walls, one needs to pay special atten- tion to overlap, bleed and the key panel. Since the Mall mural wrap created on Arlon DPF 8000 Ultra Tack and wrapped by Jirout. (Image Courtesy of Spandex s.r.o and Arlon Graphics) films today only have a maximum width of 60 inches, the graphic needs to be tiled vertically and overlaps set to ½ or 1 inch. Extra bleed on top and bottom of the graphic is necessary to compensate for walls, floors and ceilings that are out of square; longer spans can have larger variances to overcome. Due to these variables, if they cannot be foreseen, it is best to dry fit the first two or three panels by taping them up on the wall, making sure they are plumb, and make the necessary adjust- ments before proceeding with the application. Always evenly split the difference of the top and bottom bleed to make sure the graphic is vertically centered." "For someone just starting out in the industry, walls, windows and floors would be the most simple installs, says Walton. "That being said, the introduction of low VOC paints has created some challenges with adhesion, so testing the walls and using a 3M Adhesion Test Kit is crucial for a successful installation, especially when you start getting into complex contours and deep recesses. It's a great idea to get some training on how vinyl needs to be worked and what we call 'reading the vinyl,' as well as when to use heat and when not to." Calma adds that once smooth walls are mastered, textured walls are next. "The same approach applies when it comes to align- ment and setup," he says. "However, on a textured wall it will be easier to remove larger portions of the liner due to the minimal points of contact. Instead of squeegeeing down with pressure, you'll heat the film to zero tension and roll over with a foam roller to apply the film." Valade points out that interior wall wrap jobs are typically easier than external wall wrap assignments because the interior jobs rarely require lamination and are usually smaller and less labor intensive. "Interior wall wrap jobs also take place within indoor, controlled environments, so you won't have worry as much the effects of the elements." SDG Prepping a Wall for a Wrap " Once the entire wall is wiped down, take an extra piece of scrap vinyl and see how it adheres to the wall when applied. This adhesion test will show you how intensely you need to clean the wall. If the surface has been cleaned, but adhesion is poor, you may need to spray the wall to soak, dry and spray again, this time wiping the wall thor- oughly. This sweating process helps remove toxins and inconsistencies in the wall that may cause failures." —Joe Walton, 3M Commercial Solutions Division (Image courtesy of Roland DGA.)
