    What is Architectural Polyurethane?

Product Description

Quick Facts

  • Made from dense durable Polyurethane
  • Lasts a lifetime
  • Mold and mildew resistant
  • Lightweight and easy to install
  • Safe to install indoors or out
  • Exquisite detail and design consistency
  • Won't crack or splinter like wood or hard plastic

CM-1001 Crown Molding is a plain, 5-1/2" breadth crown molding typically used in rooms with ceiling heights of 9' - 10'.

uDecor crown molding is manufactured with a dense architectural polyurethane compound (not Styrofoam). Polyurethane is durable and 100% waterproof. The material can be sanded to shape just like wood.

A major advantage of polyurethane is that it is safe to install in rooms with the presence of moisture like bathrooms and kitchens. This product will not encourage the growth of mold or mildew.

This molding is delivered pre-primed for most paints. Always test your paint on a small section to make sure there are no compatibility issues with the paint and primer. Most home latex paints work great on our molding.

  • Breadth - the distance between the outer contact point with the ceiling to the bottom contact point with the wall.
  • Height - the distance between the ceiling and the bottom contact point with the wall.
  • Width - the distance between the wall and outer contact point with the ceiling. The breadth is the hypotenuse of the right triangle whose legs are the width and the height.

Our crown molding installation video, walks you step-by-step through a full installation, with plenty of tips on how to make your project look amazing. Below are some of the key things to remember.

Use Adhesive for a Lasting, Seamless Finish
Apply a small bead of adhesive along the length of the molding on the back where it contacts the wall and the ceiling (watch). Finish nails help secure the molding while the adhesive sets. Most importantly, apply adhesive between any molding being joined end-to-end.  You will need 1 tube of Loctite’s PowerGrab (or similar adhesive like PL Premium) for about every 6 pieces of molding.

The Final Piece
Cut the last piece you install on each wall just a little long. 1/16 to 1/8 of an inch is usually enough to allow you to snap that piece in place, making sure all your joints stay nice and tight. This is easiest to do when you leave the last two feet of the previous piece unnailed (watch).

Our moldings do not need to be primed. Plus, since polyurethane does not absorb moisture, paints that are self-priming or a Paint & Primer in One may not dry properly. Standard latex paint is less expensive and will give you the best result.

Be Mindful of Temperature Effects
All materials expand and contract with changes in temperature. For best results, when installing on a hot day, keep the molding inside until you are ready to make your cut.

25 Year Limited Warranty

You're making a beautiful upgrade to your home and we're here to help protect that investment. We guarantee that your polyurethane millwork will be free from manufacturing defects for twenty-five years from the original date of purchase.

Warranty Conditions and Limitations

This warranty covers material defects in our polyurethane products when used in standard applications where temperatures do not exceed 150°F. It does not cover labor, consequential or incidental damages. This warranty is not transferable and applies to the original purchaser only.

  • Polyurethane products are for decorative uses only.
  • Polyurethane products need a finish coat of paint during installation; it is the purchaser's responsibility to make sure their paint works well with the product (test and let dry on a small piece first).
  • Before installation, allow your polyurethane product to acclimate to room temperature for 15 minutes.
  • All polyurethane moldings must be installed with tight fitting joints (see installation instructions) as well as adhesive between the joints to prevent seams from expanding during changes in season.

We're Ready to Help

Unlike a car, there is very little that can go wrong with a polyurethane product since polyurethane doesn't absorb moisture and won't be affected by insects. However, in the rare event that you do encounter a defect with your product, we're here and ready to help. Just give us a call and we'll work with you to identify the problem and, in case of defect, supply you with replacements.


At, we know that projects take a while, and sometimes plans change. To start a return, please call us at 1-877-550-0600 or email; we'll be happy to assist you!

Good product - very professional finish

I would recommend this as a replacement for paint grade wood. Easy to work with, light, and dimensionally true from piece to piece.

Best room of crown molding in the house!

My husband watched the instructional videos on uDecor a few times about the installation of this crown molding. He installed the molding in our bedroom as a 50th wedding anniversary gift for me. It looks grander than the molding in the other rooms. We are very pleased.

Installed easily, love how lightweight it is!

I purchased this molding to cover an old wallpaper border in a half bath on our main floor. The order arrived lightning fast! Cutting it was straightforward with the help of uDecor's tutorials. Also, given how lightweight the molding is, I was able to install it myself with no help. It really adds dimension to the room, more of a finished look. I have more projects in mind for crown molding and absolutely intend to use more uDecor products!

Udecor tops em all!

I was apprehensive to purchase crown online but am so happy that I took the chance! First, the elaborate designs offered by Udecor cannot be found at the standard home improvement store. Udecor offers a unique selection of beautiful crown. The price is unbeatable for the design! I like the material as it is flexible, lightweight, easy to cut and install. Furthermore, Udecor shipped my materials right to my doorstep! No traffic, no waiting in lines! I have referred my friends to the Udecor website for their upcoming projects and look forward to completing my future projects with Udecor!

Looks and works perfect

There is no issue with the moldings, they are perfect but the service needs little improvements. Even for one piece order, they charged me more than the piece cost itself. Thank you for taking the time to leave a review, we're glad you like the molding! I'm sorry for any frustration about the cost. We have a minimum quantity of moldings per order due to the high cost of shipping these large pieces. Since you ordered less than that, we are forced to charge for shipping as it costs us more than what is paid. Typically it is a flat $24.99 for these moldings, but our service team made an exception for you to just pay the actual shipping cost, at $21.08. You were not charged any more than our cost. Hopefully this makes sense, but please reach out to us if you have further questions. Thanks for including us in your project!
