Hello!
I have sanded walls indoors in the basement. I now have sanding marks and need to fill them. Anyone have tips on what I should use? The following requirements:
1. I need to fill down to 0mm (which in reality will be down to sand grain size of 0.25 or 0.50, depending on what cement-based mortar/mix I can get hold of).
2. I do not want polymer/plastic mixed into the mortar.
3. I believe the plaster I sanded is not of quality A but KC.
4. Bags of 10-25kg seem appropriate to buy the mortar in.
If anyone has a good suggestion, I would be very grateful.
Best regards,
Jones

Should I interpret your responses as nobody knows if there is anything according to my wishes, or does it not exist at all on the market? I'm confused by the discussion about other things than what I wish for. Cement-based feels natural on plaster in a basement.
You have received a response from me.
Cement-based cheap tile adhesive with ballast <0.5 can be used excellently as a filler and has fantastic adhesion. It can also be sanded with sandpaper to some extent. But of course, it requires that the substrate is not too weak (you should always go from strong to equal or weaker).
But your question leaves some uncertainties:
- Have you sanded down the surface of a poor plaster layer with a concrete grinder, and are these the hollows you want to fill/skim coat?
- What final finish do you want to achieve? Should it look like plaster or be smooth or "fairly" smooth?

MagHam,
Thank you for your response!
I want it to be "quite" smooth.
It was plastic paint and the problem was that it peeled off, but on the largest area, it was so hard that I had to sand it with a concrete grinder.
I will look for a product with cement-based tile adhesive and see if it is free from polymer/plastic mixtures, and if so, I'll buy and test it. Maybe it comes in smaller bags, and then I might be able to buy a large bag...

What climate should you have in the basement and what does the outside of the basement wall look like below ground...status of drainage?...
What are you planning to do in the basement???
If you have a cold basement wall, i.e., no insulation, you need to keep the basement cool and have a dehumidifier...in that case, I would choose a cement-based tile adhesive...reinforced with fiberglass if the area is large and thick...
If it's a warm wall, i.e., insulated from the outside with Isodrän and platon mat...in that case, I would choose gypsum in clicks and drywall directly glued with gypsum mortar to the wall

I have had a very knowledgeable person here who has given me advice.
Now it is cement-based and without plastic additives according to what I have written as a request. However, I have not yet found the exact product I want to buy, hence my question here on the forum.

If the person you had as an advisor was so knowledgeable, perhaps he should have been able to advise on spackel too. But I would recommend you call Ardex, directly to a manufacturer; they should be able to help you. They have spackel for practically everything you can think of. http://www.ardex.se/ardex/kontakt.htm
I think that the person who was here for another reason analyzed and gave good explanations that I trust completely. I didn't ask about products, which I regret. I know the company but don't remember the person's name and thought I'd give the forum here a chance to help me.
However, I think we should stick to the topic, and I am grateful for suggestions that help me find what I am specifically looking for according to my question.
Thank you, Jörgen. I will contact Ardex and see if they have what I am looking for.
