Self-leveling compound - should it look like this?

What is your temperature and do you have any air circulation?
A heater that stands one meter up and blows slightly upwards to get the temperature around 18°C and for circulation isn't wrong if it's cold, but it shouldn't be necessary this time of year.

Is it okay to use a heater fan?

As Niño wrote, a fan for circulation is good but does not add heat since the spackle has its own curing time as it should harden and the moisture should evaporate on its own.

Does it usually take several days?

Self-leveling compound is usually hard on the surface and you can walk on it after a few hours depending on the conditions. But definitely not several days!

Do you know which filler was used?
Maybe there's a bag left?

Too much water or old spackel both give similar results.

Hello!
I had a craftsman pour self-leveling compound on a concrete slab in preparation for upcoming flooring installation.
After two days, it is still quite damp and soft while some parts are flaking on the surface.
Looks strange and I wonder if anyone knows if it usually flakes like this.

Have the construction fan and heater been on since the leveling?

Has the construction heater and the heat fan been on since the plastering?

Yes
