Applying the Timeless Appeal of Wood

How to treat that little bit of concrete?

In our Installation Manual we explain it is always best to create one type of underfloor in order to have to same conditions between underfloor and new floor everywhere. Often this needs to be done when two old rooms are knocked into one and where one has a concrete floor and the other existing floorboards.
See here for more details on this.

But how about having just a little bit of concrete?

We received the following questions from a "reluctant" DIY-er set to work on a new wooden floor by his better half.

Thanks for your email, the installation is coming along nicely, your book has been a great help.
It is proving a little more difficult with still trying to "live" in one half of the room.
I do have a question that maybe you could be of some help with.

I am laying on wooden floors, so using a foam type underlay, but where the fireplace was, there is a concrete subfloor measuring about 3 foot by 18 inches (sorry old school).
Am I ok to carry on with this type of underlay, or should it have a damp proof bit?

If small, keep it simple

Hi John

Thank you for your email.
Such a small area of concrete will not cause any moist problems (presumably the concrete it also "laid" on the original floorboards and not a complete thick block of concrete going way down into the void?) so you don't really need to use a DPM there.

Hope this helps. When your finished, any chance of pictures of the end result?

Not as nice as building steam engines

Thanks for your speedy reply, very much appreciated.
I have now fitted out one room, skirts to put on and then wallpaper. Boy do I hate wall papering.
But I suppose it will keep her indoors happy so that I can get back in my workshop and spend time on my real passion of building steam traction engines.
The flooring I bought does seem very good quality, and quiet therapeutic to lay. But not as nice as building steam engines.
Thanks once again


A true reflection of work well done in pictures


As requested a couple of pics.
The pics look like two different colours, but the lighter one is a true reflection. Even managed to work it so I can still get under the floor in the far corner, without it being too noticeable.
Just got the other half of the room to do now DOH.
Hope they are to your liking, and thanks once again for all your help.
