I regularly check in on several Facebook groups and online message boards for sign shops and printers. I like to look for questions to answer and ways I can help. One question I commonly see is “How do I know if my vinyl will stick to a painted wall?” or “My wall graphics are peeling after just a few days.”
Well 3M has made a 5 minute video on everything you need to know to test your vinyl, prep a wall, and make sure your print stays in place for many years.
The great thing about it is, any tools you might need can easily be found in the fishing supplies isle in your local supercenter.

Account for wall prep time in your bidding
Also above, you will find the 3M Bulletin on this topic. It’s full of all kinds of useful info on how to apply vinyl to walls without fail. The last page is the printable chart they show being used in the video.
If you need an inexpensive spring scale, they are easy to find on Amazon.
