What render or other can I use on the brick/existing render?

[Nitrex]

I have removed a door and was thinking of putting trim around it, but now I feel that I would prefer to apply render/similar and paint, as we have in another opening. The wallpaper on the adjoining walls will be replaced. The question is, what render should I use? Is there a ready-mixed product similar to filler that I can use, or do I need to buy something that needs mixing? It would be nice to avoid that if possible...

You can solve that with gypsum.

Exactly, gypsum plaster is very easy to mix, but you can also buy pre-mixed "husfix" at the hardware store.

Make sure not to apply it too thickly as gypsum plaster or "husfix" cannot be sanded (or is very hard) so it's better to apply another layer, or alternatively use regular hand putty to make it smooth and nice.

The advantage of gypsum plaster is that it can be sanded and is very easy to handle and maintain tools.
I've never used husfix but I guess it's a mix between something like 4040 and "regular" mortar? And that's not sandable, right? It's probably expensive too?

Plaster is also very hard and difficult to sand, but better than husfix.

Yes, husfix is more expensive, but it's only like a hundred or two extra for that surface, so the price difference isn't that big.

Gypsum plaster is sanded with 40 grit paper anyway, you'll have to do a spackling regardless of the base, right?

Thanks for the quick responses. It ended up being husfix anyway. I probably mixed it with a little too little water so it became a bit hard to work with. I'm going to take the other side now and test with more water, so maybe it will be easier. But how do I do it in the upper part? Will it attach well there, or do I need to "reinforce" it in some way?

Work with layer upon layer, moisten the brick beforehand so it grips better.
