Preparing for Installer Testing
The hands-on and written tests are designed to evaluate the installer's skills and knowledge in everyday situations.
An installer must possess detailed knowledge of various films and their warranted usage, durability and physical characteristics. They must be very familiar with installation techniques, tools and materials used while installing on common substrates.
Films – 3M 160, 162, 180, 181, 380cv3, 7725, 3662, 8171, 680,680CR and 983 series;
Substrates – pre-painted aluminum w/rivets, corrugated w/rivets, vehicle compound curves, bumpers, both rough textured and flat interior building walls, as well as the wall test kit and floors;
You will need to be familiar with Instruction Bulletin Nos. 5.1, 5.4, 5.5, 5.19, 5.29, 5.33, 5.35, 5.36, 5.37, 5.42, 6.5 and V-tools, as well as the use of tape primer 94 and the wall test kit.
The test is comprised of multiple choice, true or false and yes and no questions.
The films and substrates that must be tackled are those that are commonly encountered by installers. While the installations are not particularly unusual or difficult, they will be judged critically. “Show” quality work will achieve high scores. Imperfections or errors will result in deductions being made on an installer’s score.
Films – 3M 180cv3 w/mask, 7725, 380cv3/laminate and 8671/8914 series. Prespaced lettering, multi-panel full color sheets (screened and digital).
Substrates – aluminum w/rivets and hinges, corrugated w/rivets, van body, vehicle compound curve areas, Sprinter truck door, rough textured wall, flat wall, mosaic tile wall and floor.
Installers will begin with a score of 100. Deductions will be made for imperfections or errors such as wrinkles, bubbles, loose edges, tented rivets, inadequate cleaning, taking more than the allotted time for each station, etc.
A score equal to or exceeding 80% is acceptable and qualifies as “passing” for both the written and hands-on tests. A thorough review of the 3M Product and Installation Bulletins for the films and substrates listed above will be your sole responsibility. 3M Bulletins can be found by visiting their website.
