    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-1209 Crown Molding is a cove, 3-1/2" breadth crown molding typically used in rooms with ceiling heights of 7' - 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.

Very happy with this molding.

I used this molding many years ago but needed more to do a space I skipped the first time around. I ordered more and it is still as great as it was before. Easy to work with and looks great. Very happy with it.

Excellent transition

I loved working with this product. It actually was very simple to work with and because of its light weight very easy to secure using the recommended products. The quality of the material is first rate as well. I highly recommend it.

Crown moulding

Was not 100%sure what I was buying...but was pleasantly surprised when it arrived. I did not do the painting of product but guy who did said he had no complaints. Looks very nice installed and I did touch up paint and had no issues. Would highly recommend this product.

Not too bad.

The cove molding is as described. Lightweight, easy to cut and mount. However, the material doesn't take to painting very well. First coat goes on OK, but the second coat (to blend in with the ceiling) peeled and crumpled up a bit.

Looks Great- Easy to work with

This is the second time we purchased the wide crown moulding and we noticed that it had been improved by widening the flat edge on top and bottom. This makes it easier to position against the ceiling and wall. I doubt we would ever use wood for moulding again. I love the way it improved our rooms!

Fantastic deal!

This molding was exactly what I hoped for, and was so easy to install. Couldn't recommend this product enough.

Our cabinets were 'tired' so we painted them and added crown mould from UDecor. Customer service was friendly, and knowledgeable. Installed with no problems! Project not completely done but can download pix when completed.

Fantastic modern design

Added these to a set of 1998 cabinets and brought the whole kitchen into the 21st century. Look amazing easy to work with . I used white gorilla glue to bond the seams and finish nails to mount to cabinets, a quick sanding and they were ready to paint. Awesome!!!!

Not ideal

Had to purchase a 2nd order due to multiple pieces not taking to paint properly, finished look was unnaceptsble. Used suggested interior paint as described . We’re very sorry for your experience with painting our material! Unfortunately, paint formulas are constantly changing, so using a specific brand one year does not insure that the formula remained the same the following year and will work just as well. It is important to test paint on a small section of any product, not just our items, to make sure that the paint and your product material are compatible. For any future projects, we recommend ordering a sample of the molding so that you can test the paint on it before-hand. In the end, we hope your molding project turned out beautifully!

Looks great - everyone loves it!

I love how this cuts perfectly clean even though I don't have the sharpest saw blade. And it's so light weight that it was a cinch to hang. I added a little trim around made which made it a little more challenging but was worth it. The instruction video was very helpful!

Very happy :)

Couldn't be happier with the product. It was delivered on time and was very well packaged. Easy to work with (to cut and install). Everyone loves the new look of the room. Thanks for a great product.
