    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-1040 Crown Molding is a plain, 4-1/2" 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.


  • 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).

Painting
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.

Beautiful crown molding

We purchased this molding to go into a master bedroom and bathroom with 9' ceilings. It looks amazing! Our contractors were amazed at the price as well as how easy it was to work with and cut. It didn't melt like some moldings they've used in the past. Great product! Fast delivery!

Kitchen

Excellent product. Easy to install specially after watching the videos provided on your webpage. Completely changed the look of my kitchen. Gave it a fancy expensive look. I've told my coworkers and anyone that comes over my house about your product. Much better than using wood.

Nice looking crown!

This was my first time installing crown molding! After I got the hang of it this stuff was pretty easy to work with and looks great in my house. Prices are very competitive and shipping was expeditious.

Great products - Great service

I have purchased products and material from uDecor for many years. My latest purchase was crown molding for a bathroom re-model. The outside of our home is French Normandy but the inside was more modernish-minimalist, straight lines and very little basic trim. The interior did not go with the exterior, 2 very different styles. So I decided to add some architectural detail throughout my home. I am just a DIYer with NO experience so it was a little intimidating but I started slow and was surprised that the project was actually fun. I am still working at it, my house is about 4,500 sq ft. I found uDecor online and have purchase base, chair rail, crown, door and window treatments, medallions, etc, etc. from them for years and there has never been an issue. Great products, great price, great service. The changes to my home are stunning and visitors constantly comment about how great it looks. If you have ever considered adding some flair to your home then uDecor can definitely help. And, YOU can do it. Just start slow, take your time and you will soon be living in a "different" house. Good luck.

Looks great and easy to install!

We used a plank ceiling to cover up a nasty textured ceiling and needed molding to finish it off. This gave us the look we wanted, it wasn't overly expensive, and we were able to install it ourselves. We will be coming back for more!

Good product

Crown molding is a good finishing touch for an office remodel. Relatively easy to install and finish. Painted well.

Took a long time to get but like the product

We've enjoyed using this product for our full home remodel, the product works great. Orders take an extremely long time to ship, the last two orders we've placed had to be back ordered. One order took over 6 weeks to receive. So plan ahead and add a buffer into your installation timeline if purchasing products from UDecor.

Excellent Product

My carpenter painted them first and they look great up on the wall

Great end result.

I'm an average DIY er. It took me a bit to get used to cutting the corners. Let's just say I had to fill some gaps. I am happy with the end result. I do wish udecor would have some guidance on compound saw settings for the typical 90 degree inside and outside corners. The product was easy to work with. There were some discrepancies in dimensions, but they lined up well for the most part.

Inconsistent Milling

The finished side of the molding is great. Looks good and fits right, but the back of the molding is completely inconsistent from piece to piece which makes alignment for cuts, particularly miters, as well as alignment on the wall very difficult. The back of each piece should be either perfectly flat or have a consistently sized projection but not a mix of flat and multiple sizes of projections

A great finish to a room

The trim came individually sleeved and arrived in just a few days after ordering. The product cut very smooth with no splintering with just a carbide tooth miter saw. Because of the "odd angle" - I would STRONGLY recommend using the MC-4l corner blocks though - It made a possible miter nightmare into a simple straight cut. ( the only thing that wasn't available - that I was able to find i the website that would have helped was a matching outside corner block. - but since it was only one corner I was able to make it work with a little more effort. I did paint them using a Wagner sprayer and made for a very nice finish. I would definitely use this product again on future projects. I have 10 ft ceilings and this was perfect and not too overpowering but made a statement.
