How to level a basement floor
Page 1 of 2
1) I have a basement floor that is completely plastered from paint. You can see the concrete, what should be used to level it? It turned out that it's not even.
2) And how long do you have to wait for it to cure before you can place things on it?
I'm planning to put gym equipment in the room, placing a breathable mat before the machines.

I'll give you a tip. Every self-leveling compound supplier has a website. Go there and search, and you will soon find a suitable compound. Suppliers include Finja, Kiilto, Mapei, Bostik.A Anne G said:
There is also a search engine called Google, where you can search for "diffusion-open self-leveling compound" or "uninsulated basement self-leveling compound," and you will get product suggestions.
It shouldn't be a problem to find. But, I'm not going to give a product recommendation, but look for fast self-leveling compounds, every manufacturer has them because they are needed for renovations where speed is essential.A Anne G said:

I used this in the basement part of the house: https://www.hornbach.se/p/flytspackel-finja-265-fr-20kg/10226289/
Drying time 1 cm per day, but if you lay something like needle felt carpet that "breathes," you can lay the carpet earlier too, and it depends on how thick you need it.
If you haven't self-leveled before, check out some YouTube videos and divide the floor into sections so you use two bags at a time. If you can get a couple of friends to mix and carry, you can do the whole floor at once (with, for example, 6 buckets in rotation). Mix as loose as possible and keep in mind that it splatters a lot, so cover delicate items and cover walls with plastic if you’re not planning to repaint.
Also, remember that self-leveling compound isn't particularly hard as a surface, so a dumbbell or barbell can easily make dents in it.

If you are using it as a finished surface, you should use industrial putty. Self-leveling compound is intended to be covered with a surface layer. I understand that you are rather going to lay in a loose carpet?
As far as I know, all floor putties are diffusion-open.

There are some fiber-reinforced compounds that are not vapor permeable (or at least not indicated as such).L Liljeros said:
If you lay a wall-to-wall carpet, like a needle felt carpet, and then gym mats for barbells/dumbbells, it works well with regular leveling compound... (however, preferably, the gym mats should not be excessively large to avoid trapping moisture underneath them)
If it is to be used as a gym and not have gym mats e.g. 20-25mm, I recommend industrial leveling compound, a common fiber leveling compound is intended as a subfloor with a new floor of tiles, carpet or parquet,
You can find the most common ones at e.g. Beijer hornbach bauhouse, finja Weber combimix mct kilto

No, there are certainly variations for specific requirements, which I haven't encountered myself. Generally, what you buy at typical building supply stores is open, although it's of course good to double-check.anders07 said:

I understood that needle-punched mats would be placed locally under the machines, but I might have misunderstood the OP. If no other protection like rubber mats or similar is used, self-leveling compound is probably not hard enough for a dumbbell that lands incorrectly. Now, it might not matter too much if there's a mark under the needle-punched mat.

Exactly why would some brands need to specify that they are breathable if all leveling compounds were? I have a problem with the walking machine that weighs about 80 kilos; I wouldn't like the floor under the needle felt carpet that is supposed to cover the entire floor to be too soft.anders07 said:

If you lay a wall-to-wall carpet, like a needle felt carpet, and then gym mats for barbells/dumbbells, regular leveling compound works fine... (however, gym mats should ideally not be excessively large to avoid trapping moisture underneath them)
The needle felt is supposed to cover the entire room, the problem is a treadmill that weighs about 80kg, it also has a rubber mat underneath.L Liljeros said:No, there are certainly variations for specific requirements, nothing I've encountered myself.
