Forget foam, just use a thick paint.It's 1mm wide, not sure how to get foam in there.
2 coats on the cracked area - which will fill the cracks by being absorbed into the unpainted plaster within the cracks.
Once properly dry, give the area a quick light sanding with fine sandpaper.
Wipe off dust, then repaint the wall.
Quick and easy.
