Prepping a concrete lintel

Hi all

Looking to plaster the front face of this big old lintel where the previous plaster hadn't stuck very well. My plan at the minute is to apply some PVA and use bonding coat in stages to build up to the thickness of the old wall before skimming.

It is 20+mm so will likely need to apply two coats. Is this the best method or am I better to use a different product like hardwall or try and get some EML fixed onto the lintel front?

I can get plasterboard up to the underside as there will be a wooden frame under there. Would applying an anglebead to the front edge with some liquid nails against the concrete front work? Would rather not drill into the lintel.

Thanks in advance
