It does depend on what has been applied to the tape. If it's had any kind of hard filler or plaster on it then good luck sticking it back down without the filler/plaster cracking up. If that happens and you have border paste to stick it down you'll have adhesive and tons of crumbly plaster to clean up before you have to cut it out and fill it!
If it's just flexible tape with a bit of paint on it you could try border paster, usually used for wallpaper borders it's just a ready mixed wallpaper paste or any kind of pva glue might do.
Thanks, good to know. I wasn’t expecting to be able to stick it back, but wondered if there was something that could go over the top to “repair” it and cover up the edge.
This is what I’d initially found but wasn’t sure if that would do!
Paint is 12 weeks old, hence why I wasn’t keen on redoing the whole wall of all the tape had to come off…
