APPLICATION
• Apply the siding over properly prepared
walls. (see general guidelines pg 2)
• It is REQUIRED to use nailable structural
sheathing.
• Diamond Kote
®
Octagons can be installed
blind fastened.
• Start installation by overlapping a
previous course of lap siding or with a
starter strip.
(see Figure 5)
• It is recommended to use a 3/8" x
2-1/16" piece of same color lap siding as
a starter strip, as this will partially show
because of the angled bottom edge. Rip
this at a 30 degree angle, paint all cut
edges and install keeping the factory
painted edge down.
(see Figure 5a)
• For octagons installation, starting left to
right. Trim left edge so that the siding
section ts against corner board, with a
3/16" gap.
(see Figure 5b)
• Butt joint seams are not required to land
on studs.
• Do NOT place fasteners into bottoms of
grooves or shiplaps.
• Fasten the siding by 3/4" down from
the top of panel, into sheathing and/or
framing with one of the below options.
• For screws, fasten 12" on center use a
minimum #8 corrosion resistant tapered
head wood screw.
(see Figure 5c)
• For nails, fasten 8" on center use a
minimum of 6d (0.09" shank diameter)
corrosion resistant ring shank nail.
(see Figure 5d)
• Continue row, working left to right.
Overlap shiplap butt ends without any
gap.
(see Figure 5e)
• Then install subsequent courses of
siding overlapping previously installed
piece of siding a minimum of 2-1/8".
(see Figure 5f)
• Oset each course to aect staggered
joints.
• Best appearance is installing second
course starter piece 21" shorter than
the rst course. (see Figure 5)
• Start the third course starter piece
27" shorter than the 2nd course.
(see Figure 5)
• Repeat this same sequence every three
courses. Shim siding at studs, as needed,
to avoid drawing siding against uneven
walls.
