CM-1209 Crown Molding is a Cove, 3-1/2" breadth crown molding typically used in rooms with ceiling heights of 7' - 8'.

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 transition

I loved working with this product. It actually was very simple to work with and because of its light weight very easy to secure using the recommended products. The quality of the material is first rate as well. I highly recommend it.

Crown moulding

Was not 100%sure what I was buying...but was pleasantly surprised when it arrived. I did not do the painting of product but guy who did said he had no complaints. Looks very nice installed and I did touch up paint and had no issues. Would highly recommend this product.

Not too bad.

The cove molding is as described. Lightweight, easy to cut and mount. However, the material doesn't take to painting very well. First coat goes on OK, but the second coat (to blend in with the ceiling) peeled and crumpled up a bit.

Looks Great- Easy to work with

This is the second time we purchased the wide crown moulding and we noticed that it had been improved by widening the flat edge on top and bottom. This makes it easier to position against the ceiling and wall. I doubt we would ever use wood for moulding again. I love the way it improved our rooms!

Fantastic deal!

This molding was exactly what I hoped for, and was so easy to install. Couldn't recommend this product enough.

Our cabinets were 'tired' so we painted them and added crown mould from UDecor. Customer service was friendly, and knowledgeable. Installed with no problems! Project not completely done but can download pix when completed.

Fantastic modern design

Added these to a set of 1998 cabinets and brought the whole kitchen into the 21st century. Look amazing easy to work with . I used white gorilla glue to bond the seams and finish nails to mount to cabinets, a quick sanding and they were ready to paint. Awesome!!!!

Not ideal

Had to purchase a 2nd order due to multiple pieces not taking to paint properly, finished look was unnaceptsble. Used suggested interior paint as described . We’re very sorry for your experience with painting our material! Unfortunately, paint formulas are constantly changing, so using a specific brand one year does not insure that the formula remained the same the following year and will work just as well. It is important to test paint on a small section of any product, not just our items, to make sure that the paint and your product material are compatible. For any future projects, we recommend ordering a sample of the molding so that you can test the paint on it before-hand. In the end, we hope your molding project turned out beautifully!

Looks great - everyone loves it!

I love how this cuts perfectly clean even though I don't have the sharpest saw blade. And it's so light weight that it was a cinch to hang. I added a little trim around made which made it a little more challenging but was worth it. The instruction video was very helpful!

Very happy :)

Couldn't be happier with the product. It was delivered on time and was very well packaged. Easy to work with (to cut and install). Everyone loves the new look of the room. Thanks for a great product.

Great molding

I'm happy with this molding. It was easy to hang and looks very sleek. Just what I was hoping for.

looks great

We did this in our living room and hallway. We had a handyman install 900ft in 2 hours so not too hard. Looks great. I painted it before the install.

Just what I wanted and needed

For some reason my 48 year old house has molding everywhere except in one hallway leading to the bedrooms. I had always heard that I would have to have molding custom made to match the original wood molding. And then I found your website! For something not custom made, this molding is as perfect a match as there can be. My contractor was very impressed and I'm sure made note of your website. He said this product was easy to install, looks great, and will last a long time. No one can tell it's not original. Thank you!

Excellent quality, quick shipment

First time using this type of product, and am very satisfied with it. A little curious as to the rounded reverse side, as I usually put the crown in miter saw on the usual angled back. But, they have videos online that showed very simply how to cut and install. Impressed. It installed very smoothly, cuts great without blowout like some other poly products. Takes glue well (CA) and nails hold as well as wood. Will again for the next kitchen order.
