Hi,

I've lurked for a while on this forum when looking into choosing the right materials for preparing an engineered wood floor. I have to admit that i'm now only actively participating now that i have a problem(!).

I have concrete flooring in two adjoining rooms that I have damp proofed. The first room was damp proofed with Mapei DPM (2 part epoxy resin) and Lumberjack M.B Primer (1 part polyurethane liquid). The epoxy resin was applied first and then the polyurethane in the other room.

There was a delay of 36 hours to ensure both liquids were dry before another DPM was laid in the form of foiled back rubber underlay following the actual floor itself. The problem is that almost 3 weeks later the odour of the polyurethane liquid odour is as strong as it was when it was wet. Its become unbearable to remain in the same room as i believe i've become sensitised.

I suspect that by laying the underlay and floor are severely hampering any further evapouration. I'm now considering having the central heating on all day to help aid evapouration. I wish I had spent the extra money to buy more of the Mapei.

I've contacted Everbuild Technical and they say there should be no odour at all. Does anyone have any experience of doing something similar and if so when the odour will reside? The ultimate solution would be to take up the floor and start again (at huge expense) but as yet i'm still prepared to live in the kitchen!

Thanks

If they say that there should be no odour - but there is, then it looks like they have made a dodgy batch or the odour is coming from something else.

Dodgy batches do get past quality control every now and again. I have a mate that works for a paint company and they make a white emulsion that is pink when painted on- then it dries white. The only problem is that they made a batch once that did not go white!

I wonder if they liked that shade of pink!? I've tested a small patch in the garage and after 24hours it still gives off a solvent odour of you put your nose to it. So much for being 'odour free'.

I've read in various places about using sodium bicarbonate in water or sliced lemons to absorb atmospheric odours. There's also bentonite clay or fullers earth (cat litter) that might help. At the moment the central heating is on with the windows closed then after a few hours I open them. I think this is helping.

Thanks for your response.

The Bicarb might help, along with the central heating.

As for the pink paint, not many people liked it and they had to replace the faulty tins, I am not sure if any compensation was given or not for wasted time etc.
