Polyurethane Millwork - General Information
INSTALLATION INSTRUCTIONS
Storage & Handling
• Polyurethane millwork should be stored on a flat, level surface in a cool, shaded area, and should not be stored in extreme heat.
• Millwork that has been stored in a hot place should be allowed to acclimate to the installation area. Due to urethane's high insulating value,
this may take up to 10 hours.
• Handle the product with care to avoid damage. If the product does become damaged, it is easy to repair. Use wood filler or automotive
filler to quickly fill dents or gashes of any size. Broken moulding can be successfully rejoined with polyurethane compatible adhesive or
equivalent product.
Product Applications
• Fypon polyurethane products are to be used for decorative purposes only, not to provide structural support (except structural columns,
balustrade systems and porch posts).
• Fypon polyurethane products can withstand temperatures of about 140°F (60°C). However, the millwork should never be installed in an area
subject to solar temperature buildup, such as behind a storm door.
• Fypon polyurethane will resist the elements, except for direct sunlight to the yellowish (unpainted) underside of the millwork. It is important
to fill damaged or cut surfaces with putty, caulk, and/or paint within a few days.
Machining Guidelines
• Fypon products can be cut, drilled or routed similar to wood products.
Fastening Guidelines
• Proper fastening is important in limiting the effects of expansion and contraction on the product. For best results, always use non-corrosive
finish nails or screws in combination with urethane compatible Adhesive or equivalent product. Adhesive should be applied to all contact
points, including joint ends.
• Power nailers work well with this product but should be adjusted to prevent over driving the fastener into the material. This will prevent
excessive nail pressure which can result in cracking.
Finishing Techniques
• Painting - Fypon products may be painted with any good quality latex paint. Usually one coat is all that is needed. See additional information
on finishing and painting below. They are also suitable for many faux finishing techniques, including sponging, feathering and antiquing.
• Staining - Fypon Timber products are noted as Woodgrain/Stainable and may be stained with a good quality, non-penetrating stain. Apply
stain with a 2" natural bristle brush. Begin with a circular motion, then feather the stain in the direction of the grain. For a darker finish,
apply a heavy coat of stain with light pressure. For a lighter finish, apply a thin coat of stain with more pressure.
• Grout Application - Fypon Stone products do not require grout application, but it may be applied after installation to achieve a desired
appearance. A urethane-based grout is recommended and should be applied per the grout manufacturer's specifications.
Expansion & Contraction
• This product expands and contracts with changes in temperature. To minimize this characteristic the recommendations given in the Fastening
section should be followed.
• When installing this product allow
3
/
16
” per 18’ for expansion and contraction. Remember that it is recommended that all joints be glued and
where possible, fastened to the substrate to prevent joint separation.
Moulded of high-density polyurethane foam, Fypon moulded products have an in-mould barrier coat, which becomes an integral part of the urethane
foam as it cures. After each piece is moulded and trimmed, we apply an exterior grade primer. Polyurethane is a closed-cell product, making it resistant to
moisture and insects. It resists rotting, warping cracking and peeling, as well as crumbling and deterioration.
