It's time to lay flooring in the sunroom and the adjacent laundry room and storage room (floor drain, but no slope).
I originally intended to use self-leveling compound for everything, but it seems a shame since the concrete is mostly very straight, it's just a couple of spots where it's bad.
I have photographed the spots that are the most uneven. Almost all other parts of the room have the floor passing all the way, thus very straight. The bad part is mainly the boundary between two deliveries of concrete. There, you might need to alternatively grind down a bit, as it's high there.
The slab was poured a year ago and there is water-heated underfloor heating in it.
What should I do?
It would be nice to save time and money by not using self-leveling compound, of course.
What type of flooring are you going to lay? Forget about leveling screed if you have adhesive or fix that you can use to handle slight unevenness, I think.
I made the mistake of not creating a slope in the laundry room, and it's one of the things I regret today. When the washing machine gets clogged, the water flows in the wrong direction; once there was a blockage in the drain, and the water ran into the kitchen.
My tip is to use leveling compound and create a slope towards the drain even if it hurts the wallet.

That sounds reasonable. I'll probably do that in the laundry room.
But let's address the sunroom question separately. Either I sand the joint between the two concrete pours or I use self-leveling compound for the entire area. It spontaneously feels smarter to sand, as it's a very small part (say one or two square meters) compared to using self-leveling compound for 40.
What do you others think? Based on the pictures I've shown, would a sander resolve this in a reasonable way?
No or maybe I find it really difficult to sand concrete even, but I've only used a handheld machine. But I would have self-leveled. I've tried 30x60 tiles but discovered that even one mm was enough for the floor to wobble and likely dent. Building up with adhesive as someone suggested, I don't believe in, personally I'd go crazy because you have to check every little step you take in all directions with a plumb line, and it has to match the next tile without denting. No, the groundwork is important for the surface finish, it should just be done and look good without too much work.
Okay, thanks for the thoughts, Kromo.
I will, together with your wise minds on the forum, consider it for a few days.
If I take a step away from the original plan and consider laminate, that is, click flooring. Are they more or less forgiving?
More forgiving it is. Furthermore, if it gives a little when you walk, maybe it’s not the end of the world either. Tiles that you stub your toes on or, even worse, that give a little are just something you have to redo. So sure, laminate is more forgiving, but I find tiles to be more stylish, durable, and more exclusive if laid correctly
I agree that tiles feel more valuable once they're in place. Right now, I'm looking to take some shortcuts that still have consequences I can live with. I've been building for years and dream of finishing someday, and I feel a bit like this:
Option 1 (original idea): level the floor with self-leveling compound + tiles, adhesive + grout. Costs about 9000 in materials from byggmax, takes a heck of a long time to install, and since I've never done it before, I have to expect beginner's mistakes, which might be trivial or could be really annoying.
Option 2 (started yesterday): sand down the highest points, laminate (costs about 4000, can be done in a day or two, and I can handle it myself)
Most of the time, I feel like "oh, it doesn't matter if it costs 5000 extra, it's not much in the grand scheme of a big construction," but at the same time, it really gets depressing that nothing gets finished and if you save a few thousand here and there, it adds up in the end.
But I'll ponder a bit more.
Thanks a lot! If you want to see details about what it's about, you can see the Facebook page in my signature.
I made a complete turnaround from how I had planned for a year and sanded and applied self-leveling compound locally and will now lay a cheap laminate floor. It all came down to me simply wanting to be done.
If I regret it in five years, I'll tile then - because I bought cheap laminate from Rusta that I can throw out the window if it doesn't last in the long run. But it should hold up well for a few years at least.
