Bad smell after floorboards being sanded...

[Pannacotta]

We had the floorboards in our bedroom sanded about 2 months ago. The gaps between the boards were filled with some kind of glue or resin, but this has left an unpleasant smell which is lingering.
Any ideas on how to get rid of it?
The room is aired everyday but the smell seems more deep seated.

Not sure but I know that under floor areas need ventilation thats the reason for airbricks in walls in sub floor areas, air passes through carpets and disipates, if youve blocked this flow then maybe you will have a prob, have you got airbricks on the outside walls?
