    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-1215 Crown Molding is a scrollwork, 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.

I did it! All by myself.

Looks great and was way easer to work with than wood. Has some flex so the non-pro can fix an oops. My first time doing this so I made sample cuts. This gave me a picture on how to setup the saw. Tip, use a wide board on the saw table so the molding is always at the same angle to the fence. I made a face side plywood pattern of the molding as it should be installed. The plywood would rest on the ceiling and the wall so as to guide the molding at the correct angles as I installed it. Always over cut so you can fine tune the final install.
