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-2015 Crown Molding is a smooth, 4-1/8" breadth crown molding typically used in rooms with ceiling heights of 8' - 9'.

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.

Read the DIY Pro Tips section about using adhesive when installing.

  • 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, including how to measure for crown molding, 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 adhesive for about every 6 pieces of molding. Our General Purpose Construction Adhesive is cheaper than Loctite’s PowerGrab or PL Premium and works just as well in most applications.

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.

Easy to use and arrived totally protected

The product is fun to work with and goes up as easily as the marketing claimed. I highly recommend using a 23 gauge pin nail-gun, no bigger.

You won't be disappointed

My Customer experience was fantastic! You can absolutely have confidence in uDecor for the follow up and providing installation instructions. Product came quickly and undamaged. Installation was fairly easy but takes your full attention. No matter what I need I feel they will have my back.

Better than expected

I really wanted real wood crown but couldn't find this exact profile so I took a chance on this plastic molding. I've been pleasantly surprised. It's easy to work with and stronger than I thought it would be.

Hi Kelly, thank you for taking the time to share your review! We're so glad that your project went smoothly. Our polyurethane molding is shipped pre-primed and ready for paint, and that smooth surface and lightweight design is often mistaken for plastic. The other benefits versus traditional wood molding is that it won't age due to moisture as it is waterproof, and it is much less susceptible to expansion and contraction with the changes in seasons. If you have any questions, don't hesitate to reach out to us. Thanks again for sharing your experience, and including us in your project!

beautiful, smooth and modern looking

This molding is exactly what I was hoping for. Our Kitchen cabinets are gorgeous without looking overdecorated! Less is more :) UDecor sends everything in a flash! We were amazed.

Rounded back

Looks great, but it is rounded in the back, not flat like every other crown I have ever worked with is. Makes it hard to work with.

Caryn, thank you for taking the time to share your review! We're glad to hear that you love the look. The back of the molding is designed with minimal material to reduce cost, weight, and environmental impact. You're right, traditional molding used to have a flat back, which made cutting easy, so your frustration is understandable. Using a miter box or miter saw should provide great cuts each time and, the molding being polyurethane, sanding or trimming should be a breeze. The other benefit to the design is that we can ship more per box, meaning lower costs and better value. Don't hesitate to reach out with any questions, we'd love to help! Thanks again for sharing your experience, and including us in your project.

Just the crown molding I was looking for

Love the molding, shipping was a problem

I was remodeling my home and wanted to finish before Christmas. There were 2 boxes. One was delivered 5 days despite (despite 3 messages from FedEx saying that it would be delivered earlier). The 2nd box came even later. With such a tight schedule, this delayed everything. The molding itself looks great. It makes all of the rooms look so much bigger. It is so lightweight that one person could install it rather than two. The paint went on beautifully. My sister did notice that with the high gloss paint, the moldings look exceptionally shiny - which suggests that the material is not wood. I think they look fabulous.

Looks great on my master bath, now I'm ordering more for my main bedroom. It's subtly elegant if I may use the word and easy to install per my contractor.

Excellent customer service

We ordered the crown molding and the customer service on helping select was excellent. The one we wanted was not in stock and was delayed and we received a phone call updating us on the status. We then decided to order a different piece.Everyone was so courteous and everything arrived accordingly. There was one small damaged piece and we were refunded right away. Highly recommending using uDecor!

This is second time we've ordered this crown molding. Looks great and goes up fairly easily. The light weight is so nice. Takes paint well too.
