CUTTING:

Use a ﬁne-tooth hand saw or power saw with a combination blade. Cut into the exposed face of

the material. Carbide-tipped blades are recommended.

FASTENING REQUIREMENTS:

MiraTEC trim is a non-structural decorative trim product and should not be used where structural

lumber properties are required. MiraTEC trim is designed to be applied to structural framing,

sheathing and other materials.

* Note: Nail at least 1/2˝ from the edge. Do not nail into the edges of MiraTEC trim. For 4/4 and 5/4 fascia and sofﬁt applications, MiraTEC trim can be fastened directly

to the rafter ends, double nailed a maximum of 24˝ on center. For 5/8 fascia and sofﬁt applications, MiraTEC trim must have a sub-fascia and be nailed 16˝ on center

to the rafter ends or sub-fascia. For all other horizontal and vertical applications, double nail 16˝ on center, falling on the studs.

Fasten MiraTEC trim from DO NOT nail toward the

one end to the other end. center from both ends.

BUTT JOINTS:

All joints must fall over a framing member. MiraTEC trim can be mitered, scarfed, or beveled as re-

quired. Caulk, prime or paint all ﬁeld cut and raw edges for butt, mitered, scarfed or beveled joints. For

runs less than 30 feet in length, butt joints should lightly touch. For runs over 30 feet in length, space all

butt and scarf joints 1/8˝ apart and apply sealant into the full depth of the 1/8˝ joint. Double nail all joints

on both sides as noted in the diagram.

When mitering for column wraps or corner boards, JELD-WEN, inc. recommends gluing the edges of the

trim to maintain a tight joint. JELD-WEN, inc. recommends a high quality exterior grade yellow carpen-

ters glue or high quality polyurethane adhesive. Lightly ease the edge of the ﬁnished corner with 220

grit sand paper for best paint adhesion.

FASTENERS:

Always use fasteners appropriate to the style of construction where the trim is installed. Fasteners

must be equal or better in performance (such as nail withdrawal, bending strength and corrosion resis

tance) 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 trim.

For these installations, do not use electro-galvanized fasteners, due to poor long term rust resistance.

Power or pneumatic nailing systems may be used. Visit www.miratectrim.com for information on air

pressure settings on a variety of pneumatic nailers. Tapered or bugle head fasteners are permitted when

the heads are properly sealed from moisture.

Nail heads, or any other dents, can be ﬁlled with exterior grade spackling putty speciﬁcally designed for

ﬁlling nail holes. Allow putty to dry, sand smooth with 100 grit sandpaper and spot prime before painting.

Over time, spackling putty may need to be replaced or touched up. For the best aesthetic appearance

when using the smooth side of MiraTEC trim, additional work is required. The nails should be set ﬂush

or slightly countersunk (not to exceed 1/8˝). Then apply the spackling putty as outlined above. Reapply

the putty as needed for desired appearance.

Use a nail that is appropriate to the style of construction. Do not use staples, brads, or t-nails.

GENERAL INFORMATION: MiraTEC was conceived and engineered to resist moisture, rot and termites,

so it is perfect for exterior non-structural applications. It handles like wood and is a reversible product

with a wood grain texture on one side and a smooth surface on the other. Plus, MiraTEC is building

code compliant in the U.S. (ESR-3043 from the ICC-ES) and in Canada (CCMC 14015-L from the

Canadian Construction Materials Centre).

Siding FLASHING AND MOISTURE CONTROL: The structure on which MiraTEC trim is applied should be well ventilated and dry. Do not apply MiraTEC trim over wet sheathing, or any closer than 6˝ to finished grade such as flower beds, mulch, or final landscaping per local building codes. As with all wood products, MiraTEC trim should not come in direct contact with masonry or concrete.
PAGE 3
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. GENERAL INFORMATION: Paint performance is dependent upon the quality and quantity of paint applied, and the conditions under which it is applied.

The machined profile should not compromise the physical integrity of the board or induce cracking or splitting of the product. Routed or grooved MiraTEC trim should not have any flat surfaces where water can accumulate.
