CM-1047 Crown Molding is a Modallion, 5-3/8" breadth crown molding typically used in rooms with ceiling heights of 10' - 11'.

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.

Great product!

I bought this molding for exterior installation. I was always reluctant to order these online because we cannot really tell how good it is. I got the product on time, the molding looks fantastic and the quality is exceptional. I would definitely recommend this for anyone who wants quality molding. (I will use again and again! Hope it helps!

Beautiful but retracts

Beautiful and easy to install, but product retracted/shrunk approximately 1/8 -1/12 inch when colder weather set in. Had to have painter come back and fill areas with caulk. Still attractive, but less so with the gaps.

Nice product, Very nice people

The crown molding looks wonderful, especially in the small bathroom. It dresses up the room and is water resistant too! One issue on installation was the egg and dart on the bottom does not match up with the design above it. Therefore, extra needed to be ordered for matching corners. Everyone at uDecor was very friendly and helpful.
