TRIM WITH NAIL FIN APPLICATION
• Apply trim over properly prepared walls.
(general guidelines page 2)
• It's recommended to install Diamond
Kote
®
Trim with Nail Fin over nailable
structural sheathing.
• If nailable sheathing is not present, some
face nailing may be required.
GENERAL
• Trim with nail n is designed to be blind
nailed through the attached nailing n
and with clip to help complete a hidden
fastener installation.
• Install the outside corners and trim rst
before installation of siding products.
• Start by carefully removing trim from
protective shipping packaging.
• Do not cut packaging on face of material.
Avoid drawing trim against uneven or
out of plane surfaces. Shim as necessary
to ensure acceptable trim joints.
CUTTING
• It is recommended to cut the trim with
nail n face up and to utilizing power
compound miter saws.
• Align edge of trim without attached n
against fence.
• When cutting by circular saw, it is
recommended to cut face down.
• Be careful to avoid marring the nished
surfaces.
SEALING
• Paint and/or seal ALL cut ends and edges
of trim. (Figure 7a pg. 17) Cotton swabs are
recommended for touch-up painting on
the nished face.
TRIM NAILING REQUIREMENTS
• Hand-driven galvanized roong nails are
recommended for installing trim with
nailing n.
(1-3/4" StormGuard
®
Ring shank
nails from Maze Nails are recommended).
NOT RECOMMENDED to use pneumatic
roong, or siding nail guns to install trim
with nailing n.
• When attaching siding, avoid nailing
closer than 1-1/2" from the end of
the board so the power nail does not
penetrate the nail n.
• When installing trim over up to 1" rigid
foam sheathing, be careful not to drive
nails so hard as to compress the foam
and distort the n.
OPTION 1: TRIM CLIPS & NAIL FIN TRIM
• Position the clips, tight on the sides and
bottom of the item to be trimmed out
and leave a 3/8" gap between clips and
top of item. Nail through the clips into
substrate.
• Place clips no greater than 16" o.c.
around the item. Then measure and cut
the trim to length.
• Cut trim for windows/other openings as
shown Fig. 7C.
• Place trim on wall; make
sure the edge with the kerf
and dado is faced towards
the clips. Starting at one
end of the trim align and
slide the rst clip into the
kerf side of the trim. Using a
slight up and down motion
continue rotating the trim into position
with the trim clips. Hold the trim with
nail n against the wall, level, plumb
and set it to the correct height before
nailing it. Make sure to leave a proper
gap between trim and windows shown in
Fig. A
(pg 21)
• Make sure that you do not overdrive
nails. Fasten EVERY 3RD HOLE.
• Nail head should set rmly to the face of
the n, but be careful to not overdrive to
distort or damage the surface.
• Shim at trim intersections as needed
to establish ush and tight joints. Then
apply sealant.
