A wood subfloor is much more suitable for a solid
wood floors, because usually solids are 3/4 in. thick and get nailed
down with a neumatic 3/4 woodfloor nailer. Underneath the 3/4 wood
flooring, a black felt is usually installed. Other than the felt, a 15
lb. roofing paper can also be used. There are different types of
padding. Some manufactures make padding with extra cushion. Extra
cushion in a woodfloor can be a good thing because it is softer on
your knees in the long run. The National Woodflooring Association
recommends you do not glue a solid to a concrete floor. If you
absolutely must have to, a concrete moisture barrier must be
applied first before proceding to install. Here are 2 ways this can
be achieved:
- First 6 mil of polyethaline, or black/clear plastic is
installed. Next a 3/4 in. subfloor CDX is nailed down with a 22 or
27 caliber nail gun every 8 sq. in. Next, a black felt paper
[intalling this helps reduce the squeeking between wood floor and
the 3/4 in. subfloor. Then the wood floor gets nailed down. The
only issue with this is that your floor gets raised about 1 1/2in.
Now the other option is this:
- A chemical moisture sealer has to be applied. Each manufacturer
recommends its own type of sealer. Normally, this sealer gets
applied to your concrete floor and it has to dry first which
usually takes around 24 hours before being able to apply the glue.
Once this has taken place then can a 1/2 in. or below solid
hardwood floor can be installed.
