Wallpaper and Wallcoverings - self adhesive borders in a bathroom?

I have a problem that maybe you can help me solve.... I purchased the neatest self-adhesive border to put on my boy's bathroom walls. The borders are made by Imperial and goes by the name of Impact. The borders come in packages of 5 yard amounts. It was after I opened the package and read directions that I discovered that it suggests that if using in a bathroom that there is proper ventilation....or if hung in places with high humidity that I should apply under high humidity conditions??? Can you give me some suggestions about what I could do to make sure the border doesn't bubble of wrinkle. I would really like to use the border.
Is there something I could put on the back of the border to ensure that it will stick over a long period of time or is there something I could seal the border with after I get it in place?
Help????
Thank you,

If you will hang the border with border adhesive it will stay where you put it.I have done this,it works.
