STEP 16. OPTIONAL VINYL SIDING
It is recommended that aluminum, galvanized steel, or other
corrosion resistant nails, staples, or screws be used when
applying vinyl siding. Make sure wall is at and plumb. A
weather resistant barrier should be applied before installing
vinyl siding. All fasteners must penetrate no less than ¾"
into the framing or furring material. Fasteners should
be a maximum of 16" apart in siding panels and 10" apart
for J-trim, inside and outside corner posts, and starter strips.
These need to be installed at the gable, around doors and
windows and on corners before vinyl siding is applied. For
starter strips, measure the space between corner trims at the
bottom of one side of your shed. Snap a chalk line to keep
your strip level. Fasten in place.
Cut a piece of 8" nominal siding to t onto strip. When installing
siding panels, push up from the bottom until the panel is fully
locked onto the piece below it. Do not drive the head of the
fastener tightly against the siding nail hem. Allow 1/32" gap
between head of fastener and nail hem. If a fastener is installed
too tight it may cause the siding panel to buckle or distort. Start
in the center of the siding panel and work your way towards
the ends. Drive fasteners in level and straight in the center of
the nailing slots to allow for expansion and contraction of vinyl
siding. Continue all around the building, making sure the siding
at corners are at the same level and match up. Continue up the
wall, leaving a 6" exposure of the previous piece of siding.
When you reach the gable, install siding into gable starter course
and mark it with the corresponding angle by placing a scrap
piece of siding along top of gable. Continue process through the
entire gable.
The last course of siding under the eaves or windows will have
to be cut in order to t. Measure from the inside of the J-trim to
the base of the upper lock on the panels and subtract ¼". Mark
and cut the panel at this dimension. Using a snap lock punch,
punch the vinyl siding along the cut edge every 6", so the raised
lug is on the outside face of the siding. Push the siding into the
J-trim. The raised lugs on the siding will catch the J-trim and
hold it in place.
