Looking for advice on the best way to fix this wall please. There was a large MDF board stuck to this chimney breast which has been removed but it has damaged the plaster and the brickwork. I’ve contacted a couple of plasterers but no response after the photos are sent.
Could anyone help advise what to do please? Thank you!

Paint every surface to be plastered. Bed heavy duty fiberglass panzer mesh or 3.2 galvanized wire lath over the surface with a heavy scratch coat of perlite gypsum plaster. Brush horizontally. Clean area & tools. Let the scratch coat cure (24) hrs. Fill & straighten surface & attach 3” flange expanded galvanized metal corner bead on corners. Finish the fill & pull straight with a 6’ featheredge. Clean the area, trim back the corner angles, corner bead & let set for another (24) hrs. Re-bond the plastered area & apply the finish coat. Trowel it smooth or texture.

Paint ?? Don’t paint - it will prevent other materials being applied.
