    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-1300 Crown Molding is a smooth, 4-3/4" 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.

  • 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.

Crown molding

Good product, way to adjust for placement. Only issue I have is the exorbitant fee charged for only buying a few pieces. Otherwise good transaction, quick shipping, good packaging. Hi Margaret, thank you for taking the time to share your review! We're so glad you like the molding and your experience overall. Please forgive us for the shipping fee on small orders. We would love to ship ALL orders for free, but since even the smallest order of molding ships in a large 8-foot-long box, the actual shipping cost sometimes exceeds even the price of the molding. We have the $24.99 shipping fee to allow us to keep prices low and ship all orders free that meet the minimum quantity (usually) 6. We understand that it is an inconvenience, and really appreciate that you are understanding enough to rate your overall experience highly. Thank you again for the review and for your business!

Great look and everyone loves it

The Crown Molding adds to the look of our foyer, dining room, living room, hallway. Open concept and Crown Molding really looks great. Our contractor remarked on how light but sturdy the molding was made. He installed 200 Feet by himself in 2 days. My Wife is thrilled with the end result! Great Product!

Shrinkage causes more work.

I purchased this product for use outside, the instructions on-line stated there would not be shrinkage or expansion due to temperature changes. I was not pleased at needing to fill in gaps caused by temperature changes. We used the foam type crown throughout our home during construction and are pleased with that installation so we decided to use it outside. We used PVC in our patio area and needed to make repairs and adjustments. After reading your statement that the product is not affected by temperature changes we placed an ordered. The crown looked good after installation, but over night the weather cooled and the joints separated.

Looks spectacular!

We really enjoyed working with this product. It was nice that they were so light. My husband was able to do it himself. After dealing with the wood type I would choose this product again in a heartbeat.
