I have a 15x15 room that needs new hardwoood flooring. The old
flooring is removed and the subfloor is 1x4s. They are 60 years old
and shrunk a bit but generally in good shape. (I will have to replace
one or two that were destroyed when the oak floor was removed.
My question, should I attach each subfloor board at each joist? I know
with plywood it's a good idea to install extra fasteners to make sure
it's stable, but what about plank subfloors?
Bernie,yes u do nail or screw your subfloor boards at each joist.
Because your housei s that old the 1x4 may be a full 1" thick,
so there would be no reason to put any other blocking in inless
u feel that its needed.
Ordinary nails might back out, but consider using ring shank nails
with a nail gun. One compelling reason is that older houses often have
rather hard joists and in my experience a fair number of screws tend
to break off with a fast impact driver, and using a drill/driver is
slow and tedious. Make the best choice to suit your situation. Good
You have been way to helpfull, so I will have to take advantage of you,
As long as we are talking fasteners, I'm using a 16g nailer for the face
nailing. How long of nails do I need? Normal logic says; 3/4" material, then
3xs that for fastener length. But in this case, the sub floor is only 1" at
best. How long do you recommond.
Also, I have a narrow crown stapler also available. I wasn't planning on
using it because of the larger hole to fill. Which do you recommend.
Thanks for all your help!
