When can we lay floor on new screed?

[TotalNovice]

Hi All,

A new screed (3" max) was layed just over two weeks ago in our extension. I know that it will take something like four months to dry completely. But can we lay our solid oak floor at some point before this?

Would it be practical and reliable to purchase a surface damp meter? If so, what reading should I be looking for? Am hoping the hot weather has helped, and the flooring is already out of the box (which I gather is the WRONG thing to do...).

Any tips gratefully received.

Thanks, Breezer, tried a search but no joy

I also have another question: the guy who sold us this oak flooring said that no underlay was required. Was he talking out of this hat?

From what I read here, dpm/sound insulation is required when fitting on screed.

If the concrete moist level reaches around 3% moist you could apply a primer to seal the rest of the moist (but it is still better to wait until the floor has dried out completely on its own). Ventilate as much as possible to 'speed' up the process.
As for hydrometers, ask a professional fitter to check the level (instead of buying a proper - expensive - tool your self).
See here for examples of proper tools (using the Carbide Method the moist in the concrete should be between 1.7 - 2% before you can install the wood)

Your supplier is thinking of glueing the floor down, but specially with new concrete floors it's recommended to install the floor floating, using DPM and sound-insulation.

Hope this helps

Thanks WYL, I guess we just have to grin and bear the fact that our new room will not now be done til late August. Otherwise it's an awful lot of money to throw away when the wood starts to come up. At least I am at home with the kids so the French doors are constantly open at the mo, will start checking the moisture content in about six weeks time.
