Urethane trim is precision molded and non-porous. Urethane has a closed cell structure that blocks the absorption of moisture. This prevents the damage that can lead to the frequent upkeep and replacement of wood trim. Urethane offers a traditionally stylish, durable and cost-effective alternative to other materials. Basic urethane trim accents walls, windows, furniture and more. The basic design of this trim product leads to versatile applications ranging from simple to grand. Flat trim moulding can be handled and installed like wood. It is pre-primed and immediately ready for finishing.
