Help Vinyl Doesn't Stick!

I am looking for some help. I am currently working on a project to possibly do a couple of car toppers or the signs that pizza places put on the top of their delivery vehicles. The big problem though is that the plastic they are made from is so smooth the vinyl doesn't want to stick to them. When I try and pull the premask off the graphic comes back off with it.

I was wondering if anyone had ever had a situation like this and if so what could you use to help get the vinyl to stick. Any advice would be greatly appreciated. Thanks in advance.

I've had this problem before. The plastic the car toppers are made from is a very "unstable" product. It continues to gas out and forces the vinyl away from the surface. The manufacturer usually provides a vinyl swatch with a very aggressive adhesive that you lay down first and then put your vinyl on top of. This does not always solve the problem. The best way seems to be to carefully heat the surface with a blow torch to burn off the gases or bake it in 200 degree oven for a few hours. Watch carefully for any deforming of the plastic. When it is cooled you should be able to apply your vinyl. We found the same problem with plastic a-frames and solved it by putting the graphics on a coro panel and then attaching it to the a-frame.

Thanks everyone for your tips I really appreciate it. Metrosignmn I also had that same problem with A-frames and found out really quickly that you needed to put it on Coro and then attach the coro.

Thanks again everyone.

This is such nonsence. It has nothing to do with "outgassing" The word outgassing is just another excuse for not knowing what the real problem is. Just another excuse that noobs use for a reason to blame something other than their own lack of experience.

That type of plastic needs something called corona treatment. Essentially use a blow torh to heat the surface to heat treat it. Not till it blisters but just before it changes color or blisteres.

In fact there is a patent on heat treating plastic.
