1. Snap a chalk line across the I-joists four feet in from the wall for panel
edge alignment and as a boundary for spreading glue.
2. Wipe any mud, dirt, water, or ice from I-joist flanges before gluing.
3. Spread only enough glue to lay one or two panels at a time, or follow
specific recommendations from the glue manufacturer.
4. Lay the first panel with tongue side to the wall, and nail in place. This
protects the tongue of the next panel from damage when tapped into
place with a block and sledgehammer.
5. Apply a continuous line of glue (about 1 ⁄
4
-inch diameter) to the top flange
of a single I-joist. Apply glue in a winding pattern on wide areas, such as
with wide flange joists and double I-joists.
6. Apply two lines of glue on I-joists where panel ends butt to assure
proper gluing of each end.
7. After the first row of panels is in place, spread glue in the groove of
one or two panels at a time before laying the next row. Glue line may be
continuous or spaced, but avoid squeeze-out by applying a thinner line
( 1 ⁄
8
inch) than used on I-joist flanges.
8. Tap the second row of panels into place, using a block to protect
groove edges.
9. Stagger end joints in each succeeding row of panels. A 1 ⁄
8
-inch space
between all end joints and 1 ⁄
8
-inch at all edges, including T&G edges, is
recommended. (Use a spacer tool or an 8d common nail to assure
accurate and consistent spacing.)
10. Complete all nailing of each panel before glue sets. Check the
manufacturer’s recommendations for allowable cure time. (Warm
weather accelerates glue setting.) Use 6d ring- or screw-shank nails
for panels 3 ⁄
4
-inch thick or less, and 8d ring- or screw-shank nails for
thicker panels. Space nails per the table at right. Closer nail spacing may
be required by some codes, or for diaphragm construction. The finished
deck can be walked on right away and will carry construction loads
without damage to the glue bond.

(1) Special conditions may impose heavy traffic and concentrated loads that require
construction in excess of the minimums shown.
(2) Panels in a given thickness may be manufactured in more than one Span
Rating. Panels with a Span Rating greater than the actual joist spacing may be
substituted for panels of the same thickness with a Span Rating matching the
actual joist spacing. For example, 19 ⁄
32
-inch-thick Sturd-I-Floor panels 20 oc may
be substituted for 19 ⁄
32
-inch-thick Sturd-I-Floor panels 16 oc over joists 16 inches
on center.
(3) Use only adhesives conforming to APA Specification AFG-01, or ASTM D3498
applied in accordance with the manufacturer’s recommendations. If OSB panels
with sealed surfaces and edges are to be used, use only solvent-based glues;
check with panel manufacturer.
(4) 8d common nails may be substituted if ring- or screw-shank nails are
not available.
(5) Recommended minimum thickness for use with I-joists.
(6) Minimum nail spacing into wide face of top flange is 2( for 10d box, 12d box, 8d
and smaller nails (3( for 10d and 12d common).
Important Note: Floor sheathing must be field glued to the I-joist flanges in order to
achieve the allowable spans. If sheathing is nailed only, reduce I-joist spans in the
Span Table by 1 foot.
