## Overview

FLEXTRIM #445 is a pre-curved, flexible polyurethane casing molding designed specifically for half-round windows between 42" and 56" diameter. It resists moisture, rot, and temperature extremes, making it ideal for both interior and exterior use. Compatible with standard woodworking tools, it ensures easy installation and a flawless finish when painted or stained with gel-based products.

## Description

Conventional woodworking tools can be used with this material. Always install moulding in a relaxed position. Use construction or panel adhesive continuously on the backside and nails to secure moulding in place until adhesive bonds. Remember – do not use staples to fasten material, keep nails to a minimum (no closer than 6 inches between nails), and do not nail closer than 3/8 inch from edge of moulding. Flex Trim is stable and will not absorb moisture and is ideal for humid environments. It is not affected by heat or cold and can withstand extreme environments. ALWAYS lay out the material to let it relax back into its original shape; this is a good time to double-check molding style and application. NEVER pre-finish the material prior to installation. The material may flex during installation and cause fractures in the finish. ALWAYS make certain that the surface you are applying the material to is flat and smooth. Flexible molding will follow any irregularities in the surface. NEVER use staples or nails with large heads. Keep nails to a minimum and away from edges to avoid "bumps" at the edge. ALWAYS use a construction adhesive in conjunction with (or in lieu of) nails or screws. This will ensure a quick and easy application and a cleaner finished look. Let material warm up to room temperature for maximum flexibility.
