Hello!
We are renovating at home, and on the upper floor of our townhouse, there was a long crack along the corner against the outer wall. I cut away the wallpaper to see how big the cavity was, and in some places, it is 1–1.5cm wide and 4-5 cm deep.
What is the best way to fill this? Foam sealant, plaster?
