Most instructions for self levelling compounds say they are not to be used for a final surface and some covering layer is required. That is not to say you will not find one that will do what you want but you will have to search for it all the off the shelf ones will not do. If it's simply a case of stopping the dust, diluted PVA does the trick.

Or diluted SBR which can penetrate better than PVA. Another option might
be some thin resin that could be brushed on, or even diluted varnish
(not tried this mind!). You want something that will soak in and cure to
a hardish finish.
