CM-1001 Crown Molding is a Plain, 5-1/2" breadth crown molding typically used in rooms with ceiling heights of 9' - 10'.

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.

Excellent product

Looks just as good as primed wood if not better. Light weight made it very easy to do alone without any help. Thr product also finshes and takes paint very well. I wish it came in longer than 8 foot runs to reduct thr amount of scarfs/seams, but honestly if it was any longer it would be a 2 man job because of how flexible it is. This was really a very minor shortfall and not enough to give it less than a 5 star rating. This product is a fantastic value for the price point. I would love to post my "after" pictures to the website if only I knew how.

Great Product and Excellent Customer Service!

Order for the first time, received the product on time. Product is light and easy to install, CM-1001 crown moldings look great on our 9' ceiling. One of the Crown Molding was slightly damage during shipment and Tomeka Shelton from uDecor was very quick in sending a replacement unit. We have installed Crown Molding on our first floor, we will come back for more in the future.
