Always wear safety glasses when cutting or nailing!
The siding is made in 4x8 sheets with grooves
cut into the face, the long edge is beveled so
that the siding overlays where they butt.
To identify which edge we want you to use,
we will refer to the edge as either the 'LAP'
Edge or the Tongue Edge. Nail siding with
8d galvanized box nails spaced 8" apart.
IMPORTANT INFORMATION ABOUT YOUR SHED KIT
Thank you for purchasing our shed kit. Read the instructions before starting the assembly of
the building. If you have any questions about assembling the kit, call 800-245-1577. Business
hours (8:00-5:00 ET) Monday thru Friday. After business hours call 724-866-HELP (4357) or
email to [email protected].
The material that is included in our kit is listed on the back page. The optional floor package,
if purchased, will be supplied by a local lumber supplier.
Our kit does not include the shingles, the quantity needed is listed on the back page. The siding
is primed. You will need to apply a finish coat using latex acrylic paint.
Most buildings are installed on a wood floor and the siding was designed to extend over the
wood flooring. If the foundation is a concrete floor cut the siding flush with the bottom of the
wall plate to prevent the concrete from contacting the siding.
The (2) two center boards on the shipping pallet can be removed and used for wall bracing.
Stacking the boards, according to size, will make them easier to find when needed. Some boards
may have colored ends. Do Not discard any material until your building is complete.
Before you begin construction, be sure to study this assembly manual. Also, obtain a building
permit and check all pertinent building code regulations.
Thank you for your purchase.

1. Stagger the 4x4 timbers as shown below. Cut (2) two 2x4- 8' boards into 2' long blocks
to secure the 4x4s where they butt together.

4. Install the floor joists cut above between the 8' joist headers. Secure with 16d galv. deck nails.
5. Place floor assembly over the 4x4s. Square floor assembly. Measure the floor diagonally
(corner to corner) and then the opposite corners; these measurements will be the same when
the floor is square. Toenail frame (headers & joists) to the 4x4 runners.
2. Cut (2) two 2x4-8' to a length of 8' -0". They
will be used for the joist headers. Layout, from
left, for 16" on center joist spacing. 'X' marks
where floor joist will be placed.
6. Cut (2) two 2x4-12' to a length of 12' -0". Layout
for 16" joist spacing, See above.
7. Install floor joists between the joist headers. Square
the floor section and install against the section
assembled above. Toenail to the 4x4s runners.

have to change. For a concrete slab, install sill sealer as a moisture barrier between the concrete
and the wall plates. Foam sill sealer can be purchased at home centers in rolls 3-1/2" or wider.

3. Cut (17) seventeen 2x4-12' treated boards to 11' -9". These will be the floor joists. Treated
lumber may be thicker than 1-1/2". Take this into account when cutting the length of floor
joists. Shorten joist measurements if necessary to obtain 12'-0" building width.

of the 2x4 gable frame when marking the location of the first truss. Continue 24" spacing
to other gable. Important: When marking the opposite wall, place the 'X' mark on the same
side of the line so your trusses are parallel when they are installed.
