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.
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.
