    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-1111 Crown Molding is a acanthus Leaf, 9-1/2" breadth crown molding typically used in rooms with ceiling heights of 12'+.

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. Loctite’s PowerGrab or PL Premium work 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.

The crown looks great but customer service may need some improvement

The crown looks great. My friends love it. It made the room look elegant. I would have given them a 5 star but I had some challenges installing the crown in a tight corner. I sent Jason an email to request for assistance, I never got a response. Though it took a while, I figured it out myself.

Hi Bankole, thank you for taking the time to share your experience! After seeing your review, Jason went back through emails and realized that yours had slipped through the cracks. This is very rare, but we are sorry for the inconvenience and for 'leaving you hanging.' Thank you for the kind words when he called, it is great to hear that your project went well and we appreciate you making us a part of it.

Very attractive and well proportioned.

The molding has a classic motif that is very nicely reproduced. The reliefs stand out and really display the pattern nicely. It takes paint very nicely. The molding has a consistent thickness, depth and width that make fitting especially easy especially when butting pieces. However, you need to check the width and height as it is not exactly as described.

Hi Robert, thank you for taking the time to share your review! Also, thank you for taking our call this morning to learn more. We want to make sure that we state the correct measurements, and you were able to help us greatly. Our website has since been updated to the most current measurements. Thank you again for including us in your project, and for sharing your thoughts!

Molding of my dreams!

I absolutely love this molding-quality is excellent and customer service was excellent too. Took a bit to get the hang of cutting this since it's so wide but totally worth the effort!

Large Crown Molding and it looks great

This large crown molding looks great and was not that hard to install. This molding is very big so cutting it was not easy using a 12 inch miter saw. Just start the cut with a miter saw and finish the cut with a hand saw. My walls were not true 90 degree corners so a gap was present in between the moldings at the corners but after caulking you can not see the gap at all. Just look at the pictures. I painted the molding before I installed it and then caulked all the nail holes and corners after it was installed. I touched up the paint with a very small brush after I completed the installation. Shipping was fast but one piece arrived broken ( not the fault of uDecor but the shipper). It was broken near the end of the section and I was able to use the remaining section to finish the project without UDecor shipping a replacement piece to me which they offered to do with no questions asked. I will use uDecor again on my next project.
