Flooring Question

Real wood flooring

I have a concrete floor(probably 20-30 years old)
Im looking to fit real wood flooring and have been told two different things.
1) It will need a waterproof membrane and then to be glued down
2)That the above is incorrect as its real wood it needs to move so needs to be laid on a floating floor with underlay?
Can someone please advise me of what is the correct way and why.
Many thanks,

First of all you need to damp test the concrete floor. Then depending on the result and the type of wood floor you are putting down i will be able to answer your question!

Hi Adam

I favour the floating floor approach as i have used this method quite alot with concrete floors.My ground floor is solid with a floating floor comprising of a dpm,flooring underlay and then solid tongue n groove floor.
Sometimes you have to consider the type of floor your laying and the usage of the area to whether you adopt the floating floor or fixed/glued down.

Good luck

You need to damp test the concrete sub floor. Then you may want to apply a d.p.m . Then i would apply a skim of latex self levelling compound, so when the floor is stuck, the adhesive will take better to the smooth finish of the latex. But choose your adhesive wisely.

Check the moisture content of the concrete. Seal floor using epoxy sealant ( Sika MB or similar) fix using a flexible flooring adhesive ( Sika, Bona, etc) to allow the floor to move.
If fitted as per method 2 - used by a number of builders there's a high cance of the floor failing( expensively)

dont do the floating floor method regarding real wood, its pron to pulling apart over a period of time also it will never give you the feel of a solid.

a damp test will be needed any good floor fitter will carry a pro meter to carry the test out.

but to be honest if you are going for wood i wood recommend a second DPM paintable as if you are going to spend the money on a good floor protect it then you have the peice of mind there will be no problems

the floor will need to be glued DO NOT porternail like someone did to a floor we replaced the other day

make shore you fitter has a good back ground regarding solid wood there are alot of people that claim to know about solids cos they can fit laminates so be carefull bad fitting means you will have problems later
