All types of self-levelling compound can be built up in layers. I would even recommend it, if you need build up your floor quite significantly (anything above 10-12mm).

Strictly speaking, self-levelling compound is not a finished floor covering. Despite it being pretty good stuff, it is designed to have a floor covering applied over it. Its purpose is mainly to provide a smooth and level surface. It is not designed to act as a wear layer, Unless you buy a specific product like…

The chipboard floor covering will start to absorb the moisture from the self-levelling compound mix, causing it to swell and blow. Very Important: Cement-based self-level also has no flexibility once it sets, so if it is on…
If you lay your Self-levelling compound and leave it overnight it will be dry by the morning. Most manufacturers state that their products can be walked on in around 4 hours.

No, You can’t directly apply traditional cement-based self-levelling compounds that you mix with water, on top of Bitumen. Further preparation of the subfloor is required. See solutions 1 and 2 below if you are using the cement-based self-levelling compound.
