FAQ
 SAWING/CUTTING
• Use standard woodworking equipment for 
most applications.
• If using a power miter saw, a carbide-toothed 
blade with 80 teeth or more is recommended.
 NAILING
• Use 6d and 8d galvanized nails.
• Pre-drilling is required at temperatures of 40˚F 
or below.
• Royal Moulding can also be installed using a pneumatic nailer, with 
stainless steel or painted head screws or with construction-grade adhesives.
 GLUING
• Temperature variations will cause PVC mouldings 
to expand and contract. To prevent open miter 
joints, we highly recommend gluing all joints on 
PVC mouldings using a quality instant glue, PVC 
cement or OSI TeQ Bond.
• When assembling, splice and return miters by gluing the mouldings 
together before installation. This will allow you to fit the joints easily, 
and fasten the trim to the wall as one unit.
• Always test adhesive brands before using.
 PAINTING
• Royal Mouldings require no painting for 
protection, but can be painted with 100% 
acrylic latex paint to achieve custom colors. 
(Scuff sanding will optimize paint adhesion, but is 
not required. A second coat may be needed to achieve desired color.)
•    To maintain warranty for custom colors in darker shades, use  
  heat-reflective paint with VinylSafe
™
 Technology from Sherwin-Williams. 
  (Dark colors are considered any color that falls within the lightness (L) 
  value of 56 to 0, with 100 being white and 0 being black.) 
NOTE: We do not recommend painting the flex of Garage Door Stop 
TOUCHUP FOR EXTERIOR MOULDINGS
• Dap® “All Purpose” Painter’s Putty®
• Minwax High Performance Wood Filler®
• Elmer’s Fill-N-Finish Light Wood Filler®
• Sherwin Williams Shrink Free Spackling®
After installation is complete, caulk and/or putty all gaps and nail holes.
 CLEANING
• Royal Moulding can be cleaned using any of the 
recommended household cleaners listed below; 
however, glass cleaner has been shown to be 
best at keeping the finish intact.
• Recommended cleaners: See list in FAQs.
• Apply the cleaning solution and immediately wipe dry for best results.
• Avoid harsh cleaners with glycol ethers, ethanol type solvents 
and/or isopropyl alcohol as they can soften the PVC finish if left on 
for several minutes.
