    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-1027 Crown Molding is a plain, 4-3/16" 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. 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.

Impressive Look

The product gives the room an upscale finished look. Product is much easier to work with than real wood moulding as it is much more flexible for those walls that are not perfectly

Easy to install looks professional

My goal was to only install crown molding in our living room. Only took me three hours to install and the DIY task turned out perfect. So I installed the Crown molding through out our entire home.

Skeptical Convert

I must admit I was a bit skeptical since I've used similar, but inferior, non-wood products in the past, but uDecor's products were fantastic. Easy to work with, easy to install, and they finish great!

Great videos, product and service

Initially concerned about using a non-wood crown molding. Turned out to be a great product that was easier to install due to its consistency. Plus, it was an excellent value.

Easy and nice looking

This product was easy to use. I was installing by myself and did what the video said to use small nails to hold in place. I painted it and then installed. Easy Peasy. I would definitely recommend. After installing this pretty crown molding I am now going to get the floor molding stuff too. Lovely product.
