Plaster pulled off wall

[cheekydollar]

Hello. We moved recently and the previous owners decided to glue a desk good and proper to the wall. With little persuasion it has pulled off massive chunks of plaster. The attached photo is the worst bit. Do you think I can repair this with filler or is something more drastic needed?

Who glues a desk to the wall anyway.

Thank in advance for any comments or tips.

I would have used an oscillating cutter to cut along the joint between desk and wall.

If the depth is more than 2 or 3mm, I would use bonding plaster then put some finish on top.

Patching plaster , remove any loose areas ( looks like lower area is loose )

Thanks. Yea in hindsight I should have used something to get between wall and the desk but could not imagine they would have stuck the desk frame to the wall as well as screwing it into the wall and skirting boards! What a disaster. Sounds like a simple plaster job then.

As per @foxhole 's post, the area below is blown. Gingerly remove the blown plaster- I would recommend using a blunt chisel to hack away the plaster, from the front rather than levering it off.

Then brush in some PVA to lock the plaster- after, use a filler of your choice. Toupret TX110 would be ideal. It is a "rapid" setting filler. It look like you only need to fill by up to 6mm.

You need to remove the raised lip of plaster. If not when you sand the plaster, you will end up with a ridge.
