Installation Guide
3 
STORAGE: Before installation, protect Primed Trim 
Boards from exposure to direct sunlight, 
water saturation, & dirt. Do not allow it to come in contact with ground. (See below for storage 
instructions.) 
AVOID 
MARRING/SCUFFING: During cutting & handling, avoid marring & scuffing Primed 
Trim Boards. 
NEVER ABOVE 18% 
MOISTURE: Before installation, ensure that the Primed Trim Boards are 
dry. Do not install Trim that has a moisture content above 18%. (See below for more on moisture 
content.) 
PRIME ALL CUTS: After cutting, re-coat all exposed surfaces with 2 coats of high quality interior 
and or exterior paint to 3 mils of dry finish. (See pages 6 for priming instructions.) 
WINDOW/DOORS INSTALLED CORRECTLY: En
sure window and doors are installed in 
accordance with the manufacturer’s instructions and local building code specifications, before 
trimming with Primed Trim Boards. 
NOT IN CONTACT WITH FOAM: 
Ensure that Primed Trim Boards are not installed directly 
over rigid foam insulation. 
ALWAYS INSTALL MATERIALS ACCORDING TO MANUFACTURER’S 
INSTRUCTIONS! 
E.  STORAGE 
STORE IN 
ENCLOSED BUILDING: Until installed, Primed Trim Boards need protection from 
direct sunlight, water saturation, and dirt. Store the Primed Trim Boards flat and off the ground on 
stringers so that moisture is not absorbed through the bottom boards of the stack. 
EXTRA PRECAUTIONS IF OUTSIDE: Protect with a waterproof cov
ering elevated in the center so 
that water does not pool on the cover. Do not completely seal the bundle, as good air circulation is 
required. Ideally, Primed Trim Boards should be stored in an enclosed building such as a garage 
prior to use. 
F.  MOISTURE CONTENT - NEVER ABOVE 18% 
Do not install Primed Trim Boards with moisture content higher than 18%, and ensure this by use o
f 
a  moisture  meter  to  gauge  moisture  content  levels  for  all  installations.  Primed  Trim  Boards  are 
shipped with an average moisture content of 10% to 12%. Storing material in humid environments or 
near concrete or dirt will increase the moisture content. Installing material in unheated or 
unconditioned environments during wet winter or summer months will also increase moisture content, 
resulting in expansion and potential joint failure. Condition the Trim Board material on the jobsite by 
allowing it to adjust to an equilibrium moisture condition. 
G.  FASTENERS 
TYPE 
Stainless steel and galvanized nails are recommended. Use No. 304 for general applications and No. 
316 for seacoast exposures. Other types of fasteners are not recommended; they can rust and 
disintegrate resulting in iron stains and streaks. For best results use “split-less” ring shank stainless 
steel siding nails. These nails have thin shanks and blunt points to reduce splitting when fastening. 
Near edges and ends, nail holes may need to be pre-drilled to avoid splitting
