bePerf Application Guide 4.21

Notes:

• Do not stretch graphics during installation. Vinyl has memory and if stretched may cause edge lifting as it returns to its original condition. • For multi panel installs; it recommended to butt end the edges. Do not overlap. • When exposing the adhesive never touch directly on edge with your fingers. This can contaminate and affect adhesion. • Avoid going directly to the edge of glass where it meets gasket by leaving 1/4" gap. o The glass may begin to curve. o There is gasket, sealant and dirt on edges. • Best practice is to use an edge sealer on any perforated films especially 50/50 Perforated film for flat window Vehicles. This can be done in several ways. o Use a liquid edge seal pen with felt tip. This is very common among trained installers. o 3M offers a liquid edge seal 6oz can. This is best applied with a small artist paint brush to edges of the perf. o Tape method. Cut ¼ - 3/8” Strips of clear cast laminate and use as an edge tape around all edges. This keeps all edges down! • If possible, allow for the perf to adhere to glass for 24 to 48 hours under stable conditions. • Best method of shipping graphics is to lay flat between protective board. If it is necessary to roll graphic, please wind onto core to prevent the Liner from Tunneling or Graphic/Laminate from wrinkling. • Always roll with the print side facing out. o Glass can have a rougher texture than the flat area. o Moisture can gather and remain for long periods.
