What do you guys think of this?

I need to hide my QS8 wires and holing the walls isn't a good option, and my wife wants crown molding.

I'm not so good with accurate cuts (maybe someday I'll get better?) and I'm attracted by the easier nature of this type of product. Anyone have an experience with it?

How is it price-wise?

Heh. Just looked at comments on one of the pages of the article, and apparently Canamould is only sold in Canada and/or is extremely hard to get ahold of. Rats.

Any other recommendations? I've come across a couple, but they both seem kind of shady.

Ken, there are some types of pre-made corner treatments where the crown mold(square cut) simply butts up to it from each side. They look quite nice, much better than the silly pre-mitred corners from the B+M stores. Price can add up if you have a lot of them though...I've made a couple of my own to great effect in places where a mitred joint was not possible(Cathedral ceiling joining flat ceiling).

Crown mold corner blocks.

I'm just doing the living room, which is a regular ol' rectangle with a flat ceiling.

Ken.C - I used the corner blocks in my dinning room. They were so much easier than wrestling with those miter cuts. I stained the blocks and the molding to match the color of the other case molding in that room. Caveat: measure twice cut once. In my case, measure 10 X's, cut once.

Ken, I would totally use corner blocks and regular crown molding. With that foam and plaster stuff, because you're using joint compound to hide the seams, you'd need to do a bunch of touch-up painting after it's up. With corner blocks and wood -- depending on the flatness of walls and ceiling -- you might be able to get away with prepainting the molding, nailing it up, and then just filling and paining the nail holes. If, on the other hand, your walls or ceiling are a bit wavy, then you should use some paintable caulk to fill the gaps. I'm guessing you have some living room wall and ceiling paint left over?

By the way, if you want to borrow my chops saw (with laser cut line), let me know.

The key word is caulk. All pro installers use it to finish the crown molding gaps.

Yeah, I checked out some stuff on doing regular crown molding, and it all looks plenty straightforward, except for the inside corners and coping, which I do not have a great degree of confidence in. I'll talk to my wife and see how she feels about it (other than "why didn't you do this a long time ago so we didn't have ugly wires on the wall?")
