Installation Instructions

TRIM & FASCIA 190, 440, 540 & 2000 SERIES
APPLICATION
INSTRUCTIONS
• When integrating ashing with a water-resistive barrier (WRB), be sure to
follow the WRB installation instructions.
• Minimum 6 inches clearance must be maintained between trim and
nished grade. (See diagram 2a)
• Trim applied adjacent to roofs, porches, patios, sidewalks, etc. must have
a clearance of at least 1 inch above any surface where water might collect.
The surface must be sloped or otherwise designed to provide proper
drainage so the trim is at no time directly exposed to standing water.
(See diagram 2b)
• A non-corrosive drip-edge must be applied at bottom edge of roong
where it meets the fascia. (See diagrams 2c and 9c)
• Install siding products only on walls whose framing members have been
kiln dried or air-seasoned to a moisture content of 19% or lower.
• Do not install siding on walls with crooked framing materials.
• Do not install siding over rain-soaked or buckled sheathing.
• In a horizontal brick frieze or band board application where the trim
meets the masonry leave a 3/8 inch minimum airspace and ash between
the trim and the masonry. (See diagram 2d)
• Do not use staples.
• TRIM MUST NOT BE IN DIRECT CONTACT WITH MASONRY, CONCRETE,
BRICK, STONE, STUCCO, OR MORTAR.
PREPARATION
GENERAL REQUIREMENTS (CONTINUED)
• For the cleanest cut and longer blade life, a ne-tooth carbide tipped
blade is recommended.
• Trim and fascia are manufactured with a special edge coating which
reduces moisture-related issues. Do not rip and/or rout the trim and
fascia, as it will leave the edges unprotected. If the trim or fascia materials
are ripped you must take special care to prime, paint and seal all
exposed wood ber as described in the nishing section.
• Climb cut the surface of the trim and fascia such that the rotation of the
blade cuts downward on the primed or prenished surface.
• Do not miter trim edges. 45 degree diagonal cuts of trim ends around
door and window opening is acceptable, as well as joining.
