    5 Tips for Finishing Crown

Product Description

  • Made from dense durable Polyurethane

  • Mold and mildew resistant

CM-1157 Crown Molding is a Plain, 3-7/8" breadth crown molding typically used in rooms with ceiling heights of 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.

Looks Great!

Delivered quickly. Was installed by a pro and really dressed up the kitchen cabinets!

Great product!

The molding has greatly increased the higher end look of our condo. We installed it in our foyer, master bedroom and living room. It looks finished and polished and we couldn't be happier. Due to COVID we haven't been able to show it off other than in photos and we get many WOWs! It was affordable, easy to work with, trim/cut to size and it is lightweight and easy to deal with when placing it up overhead. Paint went on very easily. We are recommending it to everyone.

Decent product, bad customer service...

The overall product is okay. I'll start with the negative. Many pieces had stuck on debris from manufacturing that I sanded off and/ or scratches to the material. I ordered 48 pieces of this material. 47 pieces of the correct material arrived but 1 was incorrect. I emailed and received no response. I thought maybe I wouldn't need this last piece since I ordered above my measurements. Of course i get to the end and i needed this last piece that they screwed up. I ended finishing my bathroom with small leftover pieces. Not ideal at all!!! Once the product is up, it looks nice and as we all know crown moulding really improves a space. For future needs, I wont be using Udecor again though due to the poor service.

Easy to Install

I had never installed molding before I ordered these from uDecor (neither had my Dad). The two of us together were able to get them up quickly and easily. We used a combination of adhesive caulk and finishing nails to make sure it stayed in place. The room we installed them in had 9' ceilings and the area where the ceiling met the wall was showing expansion cracks. Rather than try to caulk it (and have it show up again in a few years), we just put up molding. The room looks sooo much better now. The shipping was very fast. I'm really pleased with the product and level of service I got from this company. I only wish pre-made corners were available for this size (or that I could pay an additional fee to have corners pre-mitered for me). However, these were not too difficult to cut with a coping saw and the results look really good.

It's Going To Be Stunning

I don't know if I answered this before, so if not, here it is. I'm redoing an old Farm House and a lot of the interior can't be duplicated, and this molding is just what the House was wanting. Thanks for the great customer service a quality product and the samples, which made all difference. Les

Looks great! Nobody can tell that it is not real wood.

My installer said the product was very easy to work with and install. Something I was somewhat concerned with but was not a problem. I highly recommend this product to everyone, especially the price point it is at. Real wood would have cost me 7 or 8 times as much based on local pricing.

Looks amazing even on vaulted ceiling

Don't let anyone tell you that you can't do crown molding on a vaulted ceiling. It elevated the entire room. I love how it frames everything in, and we had some complicated elevation changes and rounded corners.

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.

Love it!

It really made my room look great. Was so easy to put up and I can't be happier. Thank you sooo much!

Looks Great

This Crown Molding really sets off the room. I was impressed that when I opened up the box each piece of Molding was wrapped in plastic to protect from scratching. Quality of product is excellent. Cut very easily and went up as easy as Crown Molding can.

Found moldings easy to work with especially since putting them up on my own very sturdy. N even for a first timer it was as complex as I had thought. Great product

Looks very nice.

I would recommend this product to anyone looking to improve the appearance of their home. It's simple yet elegant. I have two recommendations. Save your money buying a crown molding jig. I bought two and used neither. They both required assembly. the first has a scale and a pointer that you set for the spring angle. BTW the spring angle of CM-1Y is 45 degrees. Since the pointer is rounded and the scale is made of cheap plastic and hard to read it was impossible to tell if it was set correctly. the second one had positive stops at 38, 45 and 52 degrees but ended up being to bulky to use. Maybe if I had a much bigger miter saw I would have used it. I ended up using the method described in the booklet that came with the molding. (no jig) My second recommendation is to have somebody help you. I did the LR, DR, and kitchen by myself and two bedrooms with my sons help. The bedrooms went much more smoothly and quicker than the other rooms. Everyone who has seen the finished product likes (loves?) it. One guy still doesn't believe I did it. Literally. I got a great deal of satisfaction out of this project, and again would recommend it to anyone looking to improve their home. I'm considering buying at least one ceiling medallion from U Decor, but haven't found a good video explaining installation of those or ceiling rings yet.
