inch from panel edges and in an “X”
pattern within the field as shown in
the “nailing and adhesive pattern.”
2.
Allow 3/16 inch (4.7mm) space at
panel joints, and 3/8 inch (9.5mm)
space along walls and partitions.
3.
Use proper length ring shank nails
or screws to penetrate 3/4 inch
(19mm) into sub-floor: 1 inch
(25mm) into framing.
4. If omitting adhesive, panels must be
