Cellular PVC Trim
Installation Guidelines
Cutting
• Carbide-tipped blades with fewer teeth are
preferred (32 tooth blade optimal).
• Rough-cut edges are typically caused by
excessive friction, poor board support, or
worn or improper tooling.
Drilling
• Veranda trim can be drilled using standard
woodworking drill bits. Do not use drill bits
made for rigid PVC.
• Point angle - 90º-110º, spiral angle -30º,
Relief angle -10º
• Remove shavings periodically from a drill
hole as necessary to avoid heat build-up.
Routing
• Standard wood working carbide-tipped bits
with multiple flutes are recommended.
• Always start a run with new or re-sharpened
tooling.
• Secure trim to a fixed object before routing.
Milled (CNC)
• Carbide tooling is recommended.
• Use a single edge up cut spiral bit at a chip
load of 0.016" to 0.018". Run tools at 18,000
RPM’s or greater and feed speeds between
250-275 in/min (approx 20 - 25 FPM)
Moulding
• Standard wood working machinery is
acceptable with speeds of 8,000 RPM’s or
greater (the higher the RPM’s, the smoother
the surface). Feed rates are profile
dependent. For basic cuts, feet rates of 30-
50 feet per minute yields best results.
Fastening
• Use 8d nails designed for wood trim and
siding that have thin shanks, blunt points and
full round heads. Annular threads are a plus,
especially during cold weather installations.
• Fasteners must penetrate a full 11/4" into
substrate. (stud or joist)
• Fasten 2" maximum from end of boards.
• Stainless fasteners are preferred over
galvanized – Less chance of corrosion.
(galv. stripping off fasteners)
• Nail guns can be used – PSI between 80-
100 dependent upon gun, nail, outside
temperature and substrate.
• Use 7d trim screws to better control
expansion / contraction.
• In temps under 40°F pre-drilling may be
required, depending on the fastener used.
• 3/8" and 1/2" Veranda Sheet is not designed
to be ripped and used for trim applications
• These products must be glued and fastened
to the substrate.

Recommended Fastener Screws
• Fasten Master Cortex Screw/Plug System
• Simpson Strong-Tie 2 1/4" Trim Screw or
Equal (for 1X and 5/4X boards).
Recommended Fastener Nails
• 8D Nails with Annular threads (ex. Simpson
Strong-Tie Trifecta Nail). The Trifecta Nail is
available collated for use with a variety of
nailing guns.
Sealants and Adhesives
• PVC Cements: Weld-On #705, Christy’s Red
Hot, or Cellular
• PVC cement by Ze-VO Products Group.
• Methacylates with UV Inhibitors (2
components) – PVC TrimWelder by Extreme
Adhesives.
• NPC Solar Seal 900; Quad by OSI; EPI000
by OSI; Various urethane Sealants.
*Preferred sealant should be polymer-based
containing solvents.
Do not use silicone.
Bonding Veranda Trim to Itself
• Weld-On 705 PVC adhesive, Cellular PVC
Cement by Ze-VO Products Group, or
Christy’s Red Hot
