Thin strip to plaster - what to do?

[Time Waster]

We had a new hatch put in and I put up the architrave and cooving next to it. The hatch waas longer but thinner I think as they plaster boarded a boit to the outside and I had to put coving up where there was none into the corner. Thjis has left a thin strip as in 2 and 3 inches between the hatch achitrave and the new coving. It iis in a dark corner of the hallway but I would like to do a decent job. I am not great at plastering and nobody will come in to do this small patch.

So anyone with a bit of advice on doing this easily and so it looks good.

Right now I am painting everything up white to see how it looks just painted. There is a slim chance that it might not need anything or need much to make it good.

When I moved into my flat I patch a few holes with this ,very easy to apply to get a smoothish finish then with the aid of a sander I got a pretty good finish ,is it perfect no ,but no one else can see where I did the repairs although I can .
To note this was filling in very shallow holes but I would think you could fill deeper gaps by apply multiple layers

Sounds like what you're trying to cover might be prone to movement (a bolt into it). If so, the first thing it to get it totally firm and secure before using something like the tub above. Otherwise it'll just keep cracking.

Now a serious question we have multiple hairline cracks in most rooms,would this be better than mix it yourself polyfilla.because some are from previous fillings well over five years ago.

I am not claiming to be any sort of expert on this subject , I'm guessing not as it's designed to skim larger areas where as Polyfilla is designed to fill .With most of these products I go with ready mixed as you seem to get a smoother texture but it does work out more expensive

Thanks so much,i will get ready mixed polyfilla its less of a faff.

Maybe use the ready mixed skim above but tape some scrim on it first. It will help stop any cracking from movement. Hard to say without seeing a pic really.

You can get flexible filler which doesn't recrack as easily.

Rub down the high spots on the edge of the old plaster/paint first. Fill with Toupret filler, might take 2/3 coats for a perfect finish. Don't overfill each time & rub down each coat with 150grit abrasive paper on a sanding block (this will help keep the surface flat). https://www.screwfix.com/p/toupret-interior-filler-2kg/390pp?ref=SFAppShare
