Bitumen coated floor

[Fish_91]

Hi all,
I know this has been covered before but I wanted to get some clarification on the correct materials/steps.
I've a thin coating of Bitumen on my floor in a flat, this has been exposed after removing parquet flooring. I have no intention in grinding it off, just looking to seal it and place carpet on top. (There is no need to level the floor)

What am I better off using SBR or a liquid DPM? Or a mixture of the two? Can any DPM be directly applied to the bitumen? I was looking at getting the white Drybase DPM from Toolstation/B&Q?

Thanks in advance

Is it a ground floor flat ?
But if carpet above I’d go 2 coats of uzin pe404

1st floor bud.
I've now ordered sika rapid dpm. Apparently sticks to old adhesive and should seal. I think the uzin is the same stuff?

Yeah that will work. Just blade scrape any loose adhesive

I read this post with interest as I have a similar problem.

1930's house with concrete,bitumen, parquet flooring in the living room and concrete, bitumen, Quarry tile and standard tile in kitchen. The issue I have is that there's been settlement at sometime in the past and the area where the kitchen and living room meet has a dip of around 60mm !! ( none of the the standard tiles in the kitchen have cracked, so I presume it happened a good while ago and the tiles have been laid since ). I was advised remove the parquet and lay asphalt but I'm told that asphalt can't level out 60mm. Can I use the sika rapid dpm above, then SLC in the living room ? In the kitchen, remove the standard tile and lay SLC......then asphalt over the both of them, to get a consistent floor level ??

Also, does anyone know how dangerous the asbestos in the bitumen is ?? I'need to break up and trench some floor to run a MDPE water mains under stairs. Is this specialist or just face mask and water ?

No mate. You need to use an epoxy liquid Dpm in there. Ardex na 1st then DPM1c or similar.

Thanks for the reply,
So, just to confirm my understanding, We use the Ardex Na because it bonds to the old bitumen. The Ardex DPM is used to provide a new modern damp proof, and now I can level out the 60mm dip with normal SLC and finish off with a laminate flooring ?? So I can save myself £2.5K and not bother with the asphalt ??

Do the levelling 1st before the epoxy Dpm . As above it you can only go 6mm on each coat of compound
