Painting over Paint Remover?

[Morpho]

I'm painting some ceilings in my house and decided to remove the existing paint first.
I used this paint remover (https://www.toolstation.com/shop/p70267), which I had previously used on walls and it worked really well so I expected it to do the same on the ceiling.
It didn't.

It certainly changed the consistency of the paint, making it gummy and weird, but made it no easier to remove. I think it actually made it more difficult.

So now I've given up on trying to remove it, and will just paint over the existing paint.

But now I'm left with an area of weird gummy paint with paint remover in it... and painting over that sounds like a bad idea...
I've tried scraping it off, but it would take a ridiculous number of hours to remove (even though it's not that big an area).

Here's what it looks like now (took a long time just to scrape this much...):

Do I have to spend days on end just scraping this area or is there another way?

Usually for walls you need sandpaper not paint remover (few occasions were paint would have to be stripped off) but such is life.

- Wash the patch down to remove any leftovers of the paint remover. Let it dry.
- Sand it down gently (use 120 grade paper) to remove any high spots. You may need to use one of these https://www.toolstation.com/shop/p55929
- fill any damage you have done with scraping and then mistcoat the bare area only
- or mistcoat the bare area, fill any damage and mistcoat the filler again.

You should have started from an easy room and kept it simple.

And if from the sound of things you are going to sand a lot more you may also need a pole sander https://www.toolstation.com/shop/p12186 (the pole is extra). And then you might also need a roll of paper https://www.toolstation.com/shop/p77944 120 grit, or you may want an electric sander etc
