Thinking of having exposed floorboards on one room. However, concerned
that a draught may come up between the boards.
What would people suggest for sealing the gaps? I have seen
suggestions of wooden strips hammered into place, cork strips and
silicone sealant being used.
In my last house we exposed the floorboards. I used wood fillets
hammered in to the the big gaps, and used sawdust from the sander mixed
with some PVA to fill the smaller gaps. The advantage of using the
sawdust is that as we were staining the floor the sawdust in the PVA
will stain as well, and the PVA is flexable so as the floorboards move
with the central heating you should hopefully not get any warping. I
advise that you use lots of sawdust to a little PVA.
My daughter wanted to do this on her ground floors...
After looking under the floorboards she was dissuaded as there were skips
loads of dust and god knows what under there that would come through any
small gap when wind blew into the airbricks..
I have seen the wind lift the carpet in the days before a fitted carpet was
put in my dining room ( gaps in floorboards, suspended timber floor with
airblocks allowing ventilation ).
I exposed the floor last year and packed the gaps with twists of hemp rope
( very tedious, I recommend you don't bother and see if you can get away
with it ) then finished off with natural wood colour frame sealant (
It works well, and after 18 months, although there are slight gaps visible
in the sealant where the boards have moved, I reckon you'll get that
whatever you use.
