More floor Repair January 9, 2001
There was a soft spot by the door that bothered me every time I walked
over it. It was a sound piece of floor, just gave a little. I had
not replaced it during the initial floor repair stage because it did seem
fine. Since the linoleum will be installed soon, I just had to do
it now or regret it forever.
With the benefit of past experience, it took only an hour.
I roughly located the supports underneath, then cut a 8" by 8" square in
the center of the section to be replaced.
I put my arm in and felt around for the exact location of the edge of the
1x4 attached to the beam, put a tape measure in and figured where the center
of the 1 x 4's were, marked the lines on the floor and cut with a skil
saw set just deep enough to cut through the plywood and leave the underlying 1 x 4 intact.
it is important have the edge of your new board come the center of the 1 x 4 board for best support on all sides.
Once I pried the panel up with a crow bar, I had to remove some of the
big screws (I know the panel would come up more easily if you take the
screws out first, but they are gooked in there pretty well).
To remove them first try with drill with #3 phillips head (yep, it must
be a #3) , then try vice grips, if that doesn't work, just grind it off
with a grinder.
The 1x4's were like new so no replacement needed, but the screws removed
have to be replaced
The original screws went through the plywood and the 1x4 and tapped right
in to the steel frame. It will work just as well to use self tapping
metal screws to to go just through the 1x4's and attached the plywood to
the 1x4's with 1 1/2" wood screws. Longer ones will bottom out on
Cut 3/4" plywood to fit
Screw it in, then caulk, cover or whatever.
