Bitumen on concrete floor

[benners66]

I have just removed an old parquet floor and the old bitumen adhesive is left on the concrete below. It is a very thin layer but is still slightly tacky. Would it be best to remove it (if so, any ideas on the best way) or should I be looking to "skim" over the top (if so what with/how much etc.)?? I'm completly lost at the best thing to do. I've got a large area (40 sq metre) to do. Any help/ideas appreiciated!!

It probably sounds daft, but i'm removing the parquet & putting down laminate, on the normal DPM underlay etc. Don't want the bitumen to damage anything by leaving it there. The parquet is so bad condition it's not worth (nor do i have the time) to restore it!

you can get away with just laying the underlay over the top and then fitting your laminate. That is if floor is dry smooth and flat.

It's in very good condition, so I can lay straight on the top!! That would save a massive amount of work trying to clean that large area!! Cheers!

its not 100% correct but with what your fitting it wont be a problem.

I have been on the subfloor prep course at balls factory in staffordshire.
Your posts are excellent, just stumbled across this website. Could have done with your knowledge on quite a few jobs. So I might be bugging you in the near future. Cheers.

If you in the trade give uzin products a go. They also spot on. But you cant install any of there compounds on floors that read above 75% rh. They will blow with in a week. And you must always prime. Apart from that they very good.

don't forget to use a combi-underlayment with a DPM layer included. Always use a DPM layer or combi-underlayment when there's concrete involved (even if it's covered with bitumen residue)
