My living room floor (15m2) is about 120 years old. It is pine, nailed
directly (no battens) to a concrete floor which has NO DPM. The iron
nails have rusted and this has eaten into the surrounding timber causing
My original intention was to replace it myself, using oak. However, the
more I investigate this, the more complex it seems to become. The old
concrete is not smooth and so I presume I must apply a screed to level
it. Then apply a liquid DPM (something like Ruberoid Synthaprufe?) and
then use a flexible adhesive to fix the floor. The original boards have
been sanded at some time in the past, they are now 21mm deep but guess
that originally they were 1" boards. Then I am advised to use an
underlay (circa 2.5mm thick) which is going to reduce the thickness
available for the boards. Someone even suggested the best route would
be to tear up the old boards, dig out the old concrete and replace with
a new, dpm'd concrete base.
I need some sound advice or I am just going to leave the whole thing
until my daughter inherits my house!!!
Anything you can suggest will be most gratefully received.
