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).

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, not much 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.

Nonuniform profiles

The trim looks good, but unfortunately profile sizes came different which made joining a pain. Installation was hard due to the shape of the profile which didnt give stability when mitering.

Hi Mohamad, thank you for taking the time to share your experience! We're sorry to hear that you had challenges with installation. The thickness between pieces can vary slightly, which is common in the molding world, but a bit of trimming or shimming should line things right up. For cutting, turn the molding upside down and hold it against your miter saw fence for a nice, clean cut. We're here to help, so if you ever have questions or challenges, don't hesitate to reach out. Thanks again for your review, and for including us in your project!

Looking good.

The crown mold was a match to the same profile we bought over a decade ago. Contractor found it very easy to install and paint. Great looking.

Elegant replacement

We replaced the builder provided 2" crown molding in front entry, living and dining rooms with this elegant 3 1/2" tall molding. It gives the rooms much more "presence" and definition even with an 8' ceiling height. Beautiful.

Easiest crown moulding I have installed

Really pleased with the while process. It is so light you can install with one person. And the seams just disappear. Will be doing the rest of the upstairs for sure.

Incredible customer service, Fantastic products. Great value. Fast shipping. Why can't all companies follow suit?

Orders are shipped super fast. Any question gets answered almost immediately. This last order was probably my 8th or 9th. Always super smooth transaction. Do not hesitate to buy anything here. You will be a fan after your first order!

Looks beautiful and easy peasy to install!

Used this in a hallway and two bathrooms. Love that it's moisture proof. So lightweight I installed it by myself. Hint-Tack a 3" nail on the wall about an inch below the molding line, in the center of wall span, and this will hold the molding while you nail one end. Looks exactly like wood, sands easily and paints well. Been ordering from Udecor for about 8 years. Great customer service and beautiful products!

Looks Great! Contractor Asked Where Did I Find It

This crown molding exceeded my expectations. When my contractor came to install it in the living room, he couldn't get over the fact that it wasn't wood. He took a sample with him. My friends were so impressed. Great price and great service!

Modern, sophisticated look

I bought this product for my guest room. This is the first time to installing crown molding, so the product came 2 days after ordering, all nicely packed and there was no damage. I like the modern clean look of the product I end up doing the same molding for second bedroom and for the master. I will get more to complete my living room too. I do like it very much. Will get more from them, if I decided to do more in the house
