6. The pvc flat casing can be cut to length and ripped
to fit gap as shown (FIGURE 5). Fasten to framing
with rust-proof nails long enough to penetrate the
framing by at least 1-1/2".
7. Caulk the gap between the trim and siding
(FIGURES 6 & 7).
Caulking provides additional weather seal and helps
keep insects out.
PVC
Application Tips
• PVC trim can be nailed or screwed to the framing
members.
• Nailing – Use 8d galvanized (or stainless steel)
casing nails.
• Drilled pilot holes are required if temperature is
40° F. or below.
• When pilot holes are not used, make a starting
dimple with a nail set.
• Nails must be long enough to penetrate framing
members by at least 1-1/2".
• Space nails 12" on center and at least 3/8" away
from PVC edge.
• Set nails below the surface with a nail set.
• Fill nail holes with a high-performance non-sol-
vent wood filler.
• A pneumatic nail gun can be used.
Gun must be set to place nail approximately 1/16"
below the surface. Test the setting before nailing
so nails do not “blow all the way through” the
PVC. Nails must be long enough to penetrate
framing members by 1-1/2". Space nails 12" on
center and at least 3/8" away from PVC edge.
Use at least 15 or 16 gauge or larger finish nails.
• Screws may be used instead of nails.
• Use #8 stainless steel flat head screws long
enough to penetrate framing by at least 1-1/2".
Space screws 12" on center and at least 3/8" from
edge of PVC.
• Drill pilot holes and countersink for screw heads.
• After fastening with screws, fill countersink holes
with a high-performance wood filler.
