we have leveled the concrete put some 15 lb tar paper,and are using 1
x 4 strips of wood for a subfloor 12" on center without anchoring
these pieces to the concrete,we laid out five rows and walked on them
they squeaked a lot,we are considering adding more 1 x 4
any ideas guys
If the 1x4 s are not on absolutely flat concrete there will be little gaps
between the 1x4 and the concrete. If you attached them to the concrete it
MAY help by sucking the 1x4's down but the 1x4's may still bend a bit and
make the floor squeak.
Also the actual flooring is most likely not designed for laying on floor
joints (what your 1x4's basically are) but for on a continuous sub floor.
All your butt joints must fall on a 1x4 or they will be unsupported and
flex. If its standard random length 3/4" Bruce like flooring you going to
waste a ton of wood. Also the way the tongues and grooves are cut are not
designed to support a gap.
You would be better off attaching a minimum of 5/8 subfloor over your 1x4's
and then laying the new floor.
thanks for your response my subfloor (the 1 x 4 ) are are on a 90 deg
to the wood floor slats since the floor has to expand i left 3/8 space
to the walls if were to nail the subflloor or screw it the concrete
how would the floor expand without buckling
I'm curious, why didn't you just put 3/4" pt plywood
down on the felt paper, then put your wood flooring down?
Unless you already have a water problem, this should
be an exceptable method for a wood floor over concrete.
