Subfloor Suggestions
To the Editor:
I appreciated the article "A Guide to
Construction Adhesives" (9/94). It is my
understanding, however, that plywood
and OSB should always be installed with
spaces between sheets for expansion.
I am just now beginning a major project
on an unfinished house that has
had the floors installed just as in the
article — that is, glued and nailed to
the joists, with the tongue-and-groove
joints also glued, and without any
spaces between sheets. In this case,
one-inch OSB was used.
There is some swelling at the joints,
most of which seems to be from excess
adhesive. My plan was to sand the joints
flush, then install
