First I’ve used a damp sponge to remove all construction and sanding dust. Next I’m going to apply my primer.
It’s important to note that, even though this is wall is a new sheet of drywall, it’s not all the same surface.
We have mostly large expanses of drywall / greenrock (the type of drywall that’s used in wet areas ).
But at the joints , and covering where the screws and nails hold the drywall to the studs , we have joint compound . That’s the strips of white areas.
And next to the crown and door molding and the baseboards is overspray from the paint that was applied to the wood trim.

It’s important to be sure that the primer you use is suited for use under wallpaper . But also that it will properly adhere to and seal all the surfaces on the wall .

Not a big deal. Just be aware of the need for different dry times due to different surfaces the primer is applied to.
