We have produced and installed a couple of projects on HP PVC-Free Wallpaper and have been surprised by how easy it is to install. The material is prepasted just like traditional wallpaper you would find at your local hardware store.
It is applied with water on painted drywall and is a very forgiving material to install compared to some of the other options. After you wet the material and apply it to the wall, it will have a little play for lining up and taking out kinks. After the material dries, it heals and tightens to the wall dissipating any small bubbles that may have shown up in your application.
In the past, custom wall applications have typically required a seasoned installer… no more… “Do it yourselfers” have at it.
