FASTENERS:
Always use fasteners appropriate to the style of construction where the prefinished trim
is installed. Fasteners must be equal or better in performance (such as nail withdrawal,
bending strength and corrosion resistance) to 6d or 8d 16 gauge finish nails or headed
nails, long enough to penetrate 1 1/4˝ into structural wood studs or studs and structural sheathing material. Use nails with corrosive resistance equivalent to hot dipped
galvanized nails. For buildings utilizing steel studs, use ET&F fasteners: AST-075 for 4/4
MiraTEC and AST-100 for 5/4 MiraTEC. For installations near oceans, large bodies of
water or in high humidity climates, JELD-WEN, inc. recommends using stainless steel fasteners on MiraTEC prefinished trim. For these installations, do not use electro-galvanized
fasteners, due to poor long term rust resistance.

FLASHING AND MOISTURE CONTROL:

Window or door
head casing, water
table or other
horizontal trim
The structure on which MiraTEC prefinished trim is applied should be well ventilated and dry. Do not apply MiraTEC prefinished trim over wet sheathing, or any
closer than 6˝ to finished grade or final landscaping.
As with all wood products,
16˝ O.C.
MiraTEC prefinished trim should not come in direct contact with masonry or
concrete. At foundations or exterior brick veneer, the product should be separated from the masonry by metal flashing, polyethylene film, 30 lb. felt or a 1/4˝ to
1/2˝ air space using masonry standoffs. In all applications, MiraTEC prefinished trim
should not be allowed to stand in water.
Seal the trim applications to prevent water intrusion. Do not
allow water to stand on or leak behind any MiraTEC prefinished
trim. MiraTEC prefinished trim used in a horizontal application,
including window and door headers, must be properly flashed in
accordance with the siding manufacturers’, window manufacturers’, or
door manufacturers’ application requirements and local building codes.
ADHESIVES:
Glues or adhesives can be used on MiraTEC prefinished trim such as on mitered joints for outside corners or column wraps. Use a
high quality exterior grade yellow carpenters glue or a high quality polyurethane adhesive.
SEALANT:
CORRECT

Sealant is required at butt joints and where MiraTEC prefinished trim
or other materials. Use only exteSeal Joint to the manufacturer’s written
rior quality sealant that remains flexible over time. Do not use hard-setting caulk. Apply caulk according
instructions. JELD-WEN, inc. recommends caulks and sealants that meet ASTM C920. Do not use Bondo® or similar hard setting fillers
or putties on MiraTEC prefinished trim. They will crack over time due to the natural expansion and contraction of the trim.

SPECIFIC APPLICATIONS
Flashing
For applications near rooflines, such as dormer
and chimneys, the trim should be installed with a minimum of 1˝ clearance between the
1/2'' Gap Between
Trim and Flashing
roofing and the bottom edge of MiraTEC prefinished trim. At the junction of the roofing material and vertical surfaces, flashing is required
per the roofing manufacturers’ application requirements and local building codes.
When facing the skirt boards
on deck, properly flash the top
edge to prevent water from
getting behind the trim. As a
substitute for flashing, use 1/2˝
standoffs to provide a space
behind the backside of the trim
and the deck skirt board.

MiraTEC prefinished trim can be used
to make decorative shutters. The
shutter must be fastened to the home
a minimum of 24˝ on center around
the perimeter of the shutter as shown
in the illustration. Working shutters will
not be covered under the MiraTEC
warranty due to the inability to provide
adequate fastening on the non hinge
side of the shutter.
1/4˝ Clearance
MiraTEC
When vertical trim meets flashing at
the top of trim or siding, provide a
1/4˝ clearance from the bottom of the
trim to the top of the flashing.
SURFACE PREPARATION:
The surface to be painted must be free of dust, dirt, mildew and other foreign materials before painting. Wash with water and a mild
detergent to remove dust and dirt. Allow the surface to dry before painting. If mildew is present, contact a paint supply store for
recommended methods of removing and controlling mildew.
MiraTEC
TOUCH UP AND PAINTING:
1/2˝ Space
MiraTEC prefinished trim is manufactured from wood, and all exposed surfaces must be primed and/or painted according to the following
procedures:
1. CUT EDGES AND ENDS: All exposed cut edges and ends must be primed prior to or within 30 days of installation using
a high quality exterior primer recommended by the manufacturer for use on composite wood. If these edges/ends will be
exposed to the weather and will be visible, they must be topcoated using touch up paint. Any surface damages can also
be covered up with touch up paint.
2. TOUCH UP PROCEDURE: Follow all touch-up procedures as defined by the prefinisher. This includes guidelines for
surface preparation, temperature requirements, application tools, etc.

MACHINING:
MiraTEC prefinished trim can be grooved or machined to produce a variety of decorative applications.
The machined profile should not compromise the physical integrity of the board or induce cracking or
splitting of the product. Routed or grooved MiraTEC prefinished trim should not have any flat surfaces
where water can accumulate. Maintain an angle of at least 100 degrees from the vertical to provide positive drainage and to prevent moisture from standing on the surface. Re-prime all machined areas with a
high quality exterior oil or acrylic latex primer formulated for composite wood. JELD-WEN, inc. recommends using an oil-based primer.
STORAGE:
5/16'' max depth
5/16'' max depth
Examples of machining
Cover when stored outside. Keep MiraTEC prefinished trim off the
ground and dry. Excessive moisture pickup from improper storage may
affect the performance of MiraTEC prefinished trim. Do not stack material in excess of 3 units high.
Tarp to cover
MiraTEC
For job site storage, the material should be placed on stringers and
covered, preferably on concrete, asphalt, or similar surface. For all other
instances, a tarp should be placed over the ground cover under the
stringers, with the material still under cover.
