    I have a fairly damp & dusty garage floor, and would like to improve it.

    I'm thinking about painting a liquid DPC on, and then some sort of screed/levelling compound over that.

    There seems to be hundreds of different products based on different chemicals etc, will the following work:
    Then about 5-10mm of this on top:

    I'm not intending to put anything on top of the self levelling compound - is that OK? I've read conflicting opinions on the internet about it. Also, does the self levelling compound bond to the bitumen DPC, or do i need something like this: http://www.screwfix.com/p/bostik-cementone-cempolay-universal-primer-clear-2-5ltr/6065p

    Levelling compound cannot be use as a final finished floor surface,it needs to be cover with flooring, like carpet,wood, vinyl,etc.

    Depends on what you want it for - I saw some Sika floor being laid a while back that looked really good - like a glass fibre roof finish. If I remember it does have form of glass fibre in it to stabilise the surface

    You can't use it on a floor that has rising damp or has a bitumen finish.

    OK thanks, what would be the best solution to sealing/preventing the damp, and then providing a solid non-dusty floor? There's always garage floor tiles (e.g. https://www.duramat.co.uk/) but they are quite pricey, This is onyly a bog standard garage to keep the lawn mower and bits of wood in, I'm not trying to show of my sports car or something! I'd just like to be able to store stuff in it without it going mouldy.

    Could try something like Sealapol of the Sika floor coverings most of these are "sealers" not sure how they would wear - you could always overpaint with floor paiint

    Use your liquid dpm and 12mm wbp ply.
