I'm currently stripping old wallpaper in my flat, with the intention of preparing the walls for painting.
Along the edge of what I believe is a plasterboard wall, next to a cupboard door frame, I've uncovered a long, thin metal strip.
A few things I've noticed:
The metal strip sits flat against the wall, right along the edge, rather than wrapping around the corner.
It only appears to be present on one side of the corner, not both walls.
As I've removed the wallpaper, the strip has started coming away from the wall. This section of wallpaper was much thicker than other parts.
If I press the strip back into place, it springs out again.
I'm wondering whether the wallpaper was effectively helping to hold it in place.
I'm concerned that continuing to strip the wallpaper around it will cause the whole strip to come loose, turning what was supposed to be a straightforward decorating job into something much bigger!
A few questions:
Does anyone know what this strip is? Could it be a plaster stop bead, some sort of plasterboard edging, or something else?
Should I continue removing the wallpaper around it, even if that causes it to come loose?
Can the existing strip be resecured and filled over, or would it need replacing?
Is this a manageable DIY repair for someone relatively inexperienced, or something best left to a plasterer?
I'm keen to get a reasonably smooth finish before painting, but don't want to make things worse unnecessarily.
Any advice would be appreciated. Photos attached!
