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.

Installation is simplified with the use of modern adhesives. Small finish nails are used to secure the molding while the adhesives set. See below for installation instructions.

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.

When planning for crown molding, inspect the walls and ceiling to see if any vents or other objects are within the footprint of the molding. Consider mitered returns at the ends of any molding runs that may be interrupted by these items. Allow 48 hours for the molding to acclimatize to the conditions where it will be installed.

It is easier to paint the molding before installation. Working at waist level is always better than working over your head. Paint your molding before you start the installation process. Then touch up the imperfections after you are done with the install.

ALWAYS test a section with your paint of choice before committing to painting all of your molding. Paint formulations change all the time and you want to be sure there is no adverse interaction between your paint and the primer on the molding.

Joining Pieces-
Always use an appropriate amount of adhesive on the end of any of the molding being joined end to end. This prevents the molding from separating as the house walls expand and contract with temperature changes.

Last Piece on a Wall-
For a tight fit and seams, cut the last piece that is going to be on a 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.

Lining Up The Pieces-
When two pieces of molding are being joined together in a run (end to end) leave the last two feet of the open end of the installed molding loose so you can have some alignment room when you join the next piece.

Finishing The Job-
Use Spackle to fill in nail holes and painters caulk on the edges between the molding and the wall and ceiling. Touch up these areas with paint.

This crown moulding created an additional WOW factor that enabled me to place a 12' long Philips Hue light strip inside the moulding.

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.

Getting complements from everyone

The crown molding took a moderate amount of effort to install but the look afterwards was well worth the effort. The LED rope light that I installed behind the crown molding really sets in off in the evenings and works great as an indirect room light.

Excellent quality. What I loved about uDecor was I was able to order 7 samples and hold them up on my walls to see which one would work best. I have not yet worked with the material, however the sample is straight and well defined. I can't see any issues working with this product.

Profiles not perfect from one board to the next

The product was in good condition, easily paintable, and easy to cut/work with... however we ran into significant trouble when the profiles of one board wouldn't match up perfectly with the next board. This lead to significant hard edges, where one board wasn't quite as big as the next. It took a lot of effort to putty, sand, paint multiple times and in multiple places. These joints don't look great even after all the work. This was our first time putting up CM. I am not sure if this is common to all CM's, or just the polyurethane type.
