Interior brick wall clear coat?

Joe asked 5 years ago

We have an interior brick wall, which is red brick with lime mortar. The house was built in 1913, and the wall we would like to coat is in the old lean-to. It was originally partially covered with wallpaper, which is pretty degraded. We have removed most of the loose wall paper, but would like to leave the remnant wall paper, and place a clear coat over this and also the raw red bricks. we would appreciate any advice.
Thanks
