The walls on Our New Old House separated when the house settled. When we removed the wallpaper cracks as wide as an inch were revealed where the corners should have been.
As I dug out the cracks to clean them up for repair, I found evidence of some previous repairs. Shreds of clothing had been wadded into the cracks to fill in some of the space.
I repaired the cracks by filling them in, shaping the corners with some mesh tape, and smoothing them out with a corner trowel.
I’m letting that plaster set and then it’ll be ready for sanding and priming. It’s quite satisfying putting a room back together that had fallen apart at the seams.
