Installation Tips
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.
• Place nails 12" on center, approximately
3/4" from each edge.
• 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.
Fastening Trimboard
• Use fasteners designed for wood trim and wood siding (thinner shank, blunt
head, full round head) with trimboard. Use only fasteners intended for exterior
use, such as stainless steel or hot-dipped galvanized.
• DO NOT USE staples, small brads and wire nails. The fasteners should be long
enough to penetrate the solid wood substrate a minimum of 1
1
/
2
".
• Use two fasteners per every framing member for trimboard applications.
Trimboards 12" or wider, as well as sheets, will require additional fasteners.
Fasteners must be installed no more than 2" from the end
of each board.
• Trimboards should be fastened into a flat, solid substrate. Fastening
trimboards into hollow or uneven areas must be avoided. Unless product is
installed in lower temperatures (< 40°F) pre-drilling is typically not required.
Thinner trim products (3/8" and 1/2") are not intended to be ripped into trim
pieces. They are to be glued to a substrate and mechanically fastened.
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 or PVC cement.
• 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.
