I've a concrete floor and want to fit real wood floorboards.i dont want to use glue.how do i fit it?
Answers:
Even tho you mentioned you do not want to use glue...I would use a "floating floor" system. This means the individual pieces are glued to each other, rather than being nailed or glued to the floor. But I mention a couple of other possibilites here too.
As mentioned in some of the other answers, you need to put down a vapor barrier...this is simply a layer of plastic cheeting... '6 mil' thickness would work just fine (you can get this by the roll, at most hardware stores... its a heavy plastic, either clear, or black) Overlap the plastic sheeting by about a foot, and tape the seams together too. Its surprising how much moisture will come up thru a concrete floor, or if outside, how much will come up thru the ground. You can secure the vapor barrier to the concrete floor with some tape, either double sided, or just regular tape, and make a loop out of it. I would use a heavy duct tape myself, like the "Gorilla" brand duct tape. Professionally, I had access to a heavy tape like this, that you cannot find at most hardware stores... this particular brand is the closest Ive found available on the general market.
After you have the vapor barrier down, you should consider putting down a very heavy felt, or thin foam pad (not carpet padding). This will allow for sound absorption, and movement of the floor.
As for the floor itself, you have some options.... you comment you want 'real wood' -- to different people this means different things.... Here is a link to a question recently asked about the different types of flooring... take a couple of minutes to read thru it please....
