Not only does lifting film affect the integrity of the wrap and take away from the wrap look, it can cost you time to repair and the risk of an unhappy customer. Just a few simple steps can make all the difference in ensuring your happy vehicle wraps customers stay that way.

3M Commercial Graphics regularly conducts wrap installation classes and recommends these simple steps to prevent film from lifting:

Identify high-risk areas Identify all areas on the vehicle where the film may tend to lift, such as in concave channels, around door handles, inside wheel wells and all other areas that require the film to be stressed.

Always use a tape primer To promote better film adhesion, 3M recommends using tape primer, for example 3M™ Tape Primer 94, everywhere the film will be stretched. Apply a thin layer of the tape primer in those areas and let it dry for five minutes — this allows the carrier solvent to evaporate, leaving behind just the adhesive promoter. Be sure to apply the film right where you want it.  Once the tape primer is applied, repositioning the film is very difficult.

Post-heat film to reduce internal stress When the film is in place, it is very important to “post-heat” the film to reduce the internal stress that is introduced into the film. To properly post-heat, adjust the heat source so the film temperature reaches 200° F (94° C).  Move the heat source slowly across the stretched film surface and roll the film with a tool, such as the 3M Roller S tool pictured above, while the film is still hot on order to press the film in place. This helps to fully “wet-out” the adhesive onto the substrate and reduces the risk of lifting.

Do a final inspection Always do a final inspection of your work, paying particular attention to the high-risk areas. Taking that extra step pays off in the long run.
