About to lay a solid wood floor on a new concrete floor...

[no fit state]

I'll be laying a DPM first but should I check the floor with a dampness meter first? and if so what one should I buy?

The floor has been down a minimum of 6 months.

Thanks.

hygrometer. About 100-150quid . Takes 24- 72 hrs to get correct reading. Only test that is to british standard. Or protimeter 400+quid or tramex 800+ quid, Guess you wont be spending this much.

Ok, but is it something I need to do if I'm putting down a DMP first?

With your new concrete underfloor between 6 - 8 months old: YES!

I'll be able to find out on Friday how long the floor has been down, as it could have been as much as 12 months by now.

Also would this do the job? http://www.hss.com/g/49420/Damp-Meter.html

The hss hire meter is only accurate on testing real wood. It is only a indicator for concrete. We use them to find the wettest area of concrete we want to test with a hygrometer. They are good but not accurate. Like they cant tell the difference between condensation and moister trapped in the concrete slab. As woody has said tho, if the concrete base is 6 months old then there wont be a problem with combi dpm underlay.
