Simon, I picked up a few hits and misses in my flooring wallpaper remodel.

One, I used a high end very cushy underlayment before I glued the LVT down. The cushion of the underlayment was a mistake in that it gives ever so slightly I can feel the movement between the seams on the slide out floor if I am in bare feet. I know that is OCD and you don’t have a slide, but evaluate carefully any underlayment you may think about using.

You will need to install wallpaper liner before putting up the final wall paper. It is a heavy plain white paper designed to hide any surface irregularities and provide a good bonding surface for the wall paper. It is also a bit wider to avoid seam alignment issues with the final wall paper. Use border adhesive instead of normal adhesive, you want all the bond you can get.
