Skirting Board Removal Disaster

[Wingman30]

I was planning to replace the skirting boards. While removing the existing skirting, some of the wall plaster came away with it (the wall is solid, not plasterboard). I later realised that the skirting had been fixed using a no-nails adhesive.

What is the best way to repair this damage? Can I use ready-made Polycell Polyfilla? I’m a complete DIY beginner and have never done any plastering before.

I’ve attached a couple of photos for reference. I’d really appreciate any advice or suggestions.

my thoughts
its come away almost better than you could expect on average
normal is big chunks back to brick in several areas
disaster is massive chunks back to brick inches to feet above although more expected on some walls
just put the new stuff on with no nails[as whats there must be solid as it still in place ]
then filler to any visible gaps above the skirting
