    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-1066 Crown Molding is a plain, 3-1/4" breadth crown molding typically used in rooms with ceiling heights of 8'.

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!

Great product, outstanding support

Just finished installing about 50 units of crown molding CM 1066 in 5 rooms. Great parts: easy to paint, easy to cut and super clean cut, extremely consistent dimensions (part to part and lot to lot, even with months in between orders) which makes parts easy to join, lightweight which makes it easy to install (can be a one man job, with the help of a few nails...) Outstanding support: was not too sure about ordering such parts on line at first. Ordered a few only at first "to see", and I was absolutely delighted. Edde Hickey (cust. experience specialist) was extremely responsive, very helpful with technical tips, managed very well my expectations when my second shipment had to be delayed. Overall, great impact on my rooms, great price and great experience with uDecor. Highly recommended!

Great value

This was a great product, incredible value. I'm a 38 year old mom and I installed this in my bedroom in a couple hours completely by myself. Will definitely buy more for other rooms.

First Time Installing

This was the first time I installed crown molding and the product was great. I followed the instructional videos and the results looked professional. Bought other molding from uDecor but had it professionally installed. My self install was comparable. Would highly recommend their products.

Very Nice Product!

I'm very pleased with the crown molding. I'm removing the popcorn texture from the ceiling in my entire house and decided that adding crown molding would be easier than making the corner joints pretty after removing the texture. It's very easy to work with as long as you have a good miter saw and a nail gun. Note: I pre-painted molding in pics before I put it up but have not yet filled nail holes, finished joints, or touched up the paint.

Great price, great product.

Turned out great. Was hard to cut the corners, but that's because I'm a novice. The only complaint I had, was I ordered online
