Hi
Unfortunately we have never tried this before and in light of this do not know. Your best bet is to cut a very small section of wallpaper and give it a go to see if it does stick and then you will know.
In terms of sealing, again we are not too sure. You could try most types of clear varnish or possibly even a watered down PVA solution. Your best bet is to experiment and see what works
Hope this helps
