Priming & Sizing a Wall for Wallpaper

[gsiefkas]

I am a contractor who specializes in painting and wallpapering. Up to this time I was able to use Zinssers Prepz as my do all wallpaper paste. I`ve had very good results with this. Now Zinsser has stopped making this paste or at least I`m not able to buy it anymore. As you know a one application paste is much cheaper in time and labor and product than applying sizing and then paper. What will happen if I don`t use the primer or sizing?
