General Staple Down Installation Instruction:
Time at which to install hardwood flooring: Lay only after sheetrock and
tile work are thoroughly dried and all but the final woodwork and trim
have been completed. The building interior should have been dried and
seasoned and a comfortable working temperature (at least 60° F) and a
relative humidity of 35 – 55% should exist during and after installation.
DO NOT open until ready to install.
Preparation of subfloor: Subfloor irregularities and undulation may
cause any wood flooring installation to develop hollow spots between
the flooring and subfloor. These hollow spots are NOT the result of any
wood floor manufacturing defect and are NOT covered by the Mullican
Flooring warranty.
Adequate and proper stapling as
well as soundne
ss of the
subfloor should be ascertained. Foreign material shall be
re
moved from the subfloor surface and swept clean.

Laying direction for plank flooring: Flooring should be laid
at
right angles to the floor joists and, if possible, in the direction
of the longest
dimension of the room.
Note: Normally, expansion space around the room should be the
same distance as the thickness of the hardwood flooring.
The floor should be installed from several cartons at the same
time to ensure color and shade mix.
End joi
nts should never be closer than 4” from each other.
Staple Engineered Plank Hardwoo
d Flooring: The first and
