Plaster over expanding foam

you could drive some long screws at a diagonal to hold in some expanding metal. the diagonal is to stop pulling out
mind the pipe

Had to cut out around a leaking pipe under a boiler to nip up a pipe and stop a leak. Roughly round hole that I filled with expanding foam that I’ve cut back to below the surface and just wondering what the best product would be for filling/skimming over the foam and level with the plasterboard wall?
Thanks

I've used Ronseal filler; it comes ready mixed,
Excellent stuff very small crystals,

I was looking at that, gets good reviews, can it go direct onto the foam or would poly bond and tape be best first?

I applied it directly over foam in two layers, one layer slightly off the finish, then a second layer to finish,
I recessed all my radiator pipes in to the walls, filled around them with unibond white-tec foam then trimmed foam back and applied this directly, pipes are inside there four years now and the surface hasn't cracked or changed atall
Take care when lifting the tub of filler off from the shelf; it's very light, I got my hand on the shelf above as I was expecting the tub to be over 1.5kg but it's only around 500g in weight but the tub is full.

Your pictures aren’t straight, that would do my head in :pac:

They were very well marked out prior to painting the wall,
There exactly 1.5" apart all round
