I have used this in the past with some success. If it's really bad I use the fine scrim as well. Takes ages to feather it all out to make it disappear with the scrim but my hallway skirtings have not cracked in 10 years and next door dug a basement and tore all the internal walls out about 7 years ago. Buy it from wherever, the links are just the first hits on google for me.
No, layed over the top edge, 90 degree angle. It's a very longwinded process. It's just that cracking skirting boards on staircases do my head in. Mine are a different pattern though so it makes a bit more sense. I think these were done in 2010.
