Snapping A Chalk Line

Start at the lowest corner of siding or sheathing on the house. Drive a nail partway

into the sheathing at a point 3" higher than the lowest corner. (Note: This will place

the siding 3/8" below the lowest point.) Stretch a chalk line from this nail to a

similar nail at the next corner of the house, being careful to make sure that the line

is level. Continue this process around the entire house.

Install The EasyStart Strip

Position the EasyStart strip with the top edge on the level chalk line. Fasten the

EasyStart strip to the wall. Use shims to fill any hollows which may occur in the

wall surface. It is important that the starter strip be installed straight and level.

As you add sections of starter strip, always leave 1/4" space between sections to

allow for expansion and contraction. Note: Leave approximately 1/4" between the

EasyStart strip and the EasyPost outside corner post.

Installing Outside Corner Posts

Corner posts should extend 3/4" past the bottom of the EasyStart strip. Remember

to place the topmost fastener at the top of the topmost full nailslot. Center

remaining fasteners 8"-16" apart. Note: For a better finished appearance, remove

a 3/4" portion of the nail hem on both sides of the corner post prior to securing.

Installing J-channel

J-channel should be installed all along the top and sides of window and

door casings. Cut j-channels the required length plus twice the width of the

j-channel face for overlapping the j-channels at each corner. Place the j-channel

against the casing and secure it to the wall, allowing for free movement.

To trim the bottom of windows, and at the eave, j-channel can be used with the undersill

molding inside the j-channel. The j-channel & undersill combination will secure the cut

siding panel and help to keep the alignment straight. Dual undersill molding combines

both functions into one part. Cut and secure dual undersill similarly to using j-channels.

For Square Corners

Start by installing the bottom j-channel, removing a 3/4" notch from

each end. Install side j-channels by removing a 3/4" notch from the

top, and making a 3/4" drain tab at the bottom. Fold the tab under,

and into the bottom j-channel. Install the top j-channel by cutting a 3/4" drain

tab at both ends, and bending the drain tabs downward, and into the side j-channels.

For Mitered Corners

Create mitered corners by cutting 45 degree

angles in the bottom end of the side j-channels,

and on both sides of the top j-channel. To

install, follow the methods described above.
