Product Description

Quick Facts

  • Made from dense durable Polyurethane

  • Mold and mildew resistant

  • Exquisite detail and design consistency
  • Won't crack or splinter like wood or hard plastic

CM-2041 Crown Molding is a smooth, 5-1/2" breadth crown molding typically used in rooms with ceiling heights of 8' - 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.

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

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.

classy, improved appearance to bedroom

This product is replacing older 1920's 3" crown molding in bedroom w/ plaster walls. Maybe it was the installer, but it wasn't the easiest thing to secure to walls/ceiling because of uneven plaster walls and corners not square. Although I initally bought what I thought would be enough to do the job, I was short 2 pieces and had to order more. So that might something to consider if you've got an older home w/ these issues. Otherwise, the addition of this product (along w/ getting rid of popcorn ceilings) sure improved the character of my bedroom. I'll give it a 4 rating.

Top quality, great looking product.

I used this to replace the old wooden crown on the cornice over our exterior entranceway. Because it was so lightweight yet stiff, it was easy to cut and fasten into place. The consistency of shape and flawless primed finish was especially impressive. I will now plan use of their other mouldings inside my home!

Looks great, easy to install

This molding is something. Very good quality, light weight makes it easy to install. We didn't even need a nail gun, just a glue and random temporary nails. Also, it has been installed to cover up a space left after removing the old ugly molding, we were trying Home Depot, Lowes and they don't have that particular width, that makes it unique as well. In addition, ir arrived very fast with consistent updates on order. Thank you!!

Looks fabulous!

We are having the molding installed in our newly constructed home. We painted every room prior to the installation. The molding in the main living areas has been installed and it looks amazing!

Looks just like wood

The crown molding looks great and to simply look at it you can not tell it is not wood. However, it would be so much better if this product came in 12 ft. lengths. While the corners came out great, it was the joints of the straight edges on the long walls that seem to show the most, surprisingly. Make sure you order enough, we ran out and now have to wait to finish the project until more of the molding arrives as it is out of stock. Will send a photo or 2 when the project is complete.

Dana, Thank you for taking the time to share your review! We're so glad you love the look. We agree that 12ft lengths would make for fewer cuts. The reason we do not exceed 8ft lengths is to keep the cost as low as possible, to provide the best value. When a box exceeds 8ft in length, the shipping cost goes WAY up as it automatically has to ship on a very long pallet, incurring extra fees. We can't wait to see your project finished! Thanks again for your review, and for including us in your project.

Great alternative to wood crown

We love the crown molding- looks great and so easy to work with - easier to attach than wood. You cannot tell this isn't wood. So much cheaper as well. We loved it so much we bought more and did another room!

Finishes off the house. Wish I did it years ago.

Material is very nice and consistent. It cut well and went up straight. The light weight made for an easier installation. Products are good quality, price is very good, and the company is there if you need them for help and questions.
