Recovering a terrible polyurethane coving join

[Hummed]

Hi,

Any advice welcome please...

I decided to try put up "Supercove" (paper covered polyurethane) coving. Unfortunately on a long wall I needed a scarf joint, and either the walls/ceiling are not flat (they were recently plastered), or, most likely, I have the wall/ceiling alignment wrong (or both)

Anyway I'm not sure what to do now. I don't think I can sand this down as it is paper covered and I imagine it will start peeling off. I could dump filler on it and hope for some vaguely nice shape after sanding, but as it juts out a few mm I think it'll still look terrible.

Removing it seems the likely option, but I don't know how to get it off cleanly without damaging our new plaster. The adhesive is Supercoves own "glue" and it has been up between 24/48 hours.

Thanks!

A scarf joint is wrong - you need a butt joint - something I learned on my first coving job You might get away with a new section and 2 butt joints - worth a try ?

I would use a lightweight filler such as Toupret RedLite or RedDevil OneTime. Sand with 180 grit silicone carbide paper.
