Here Down Under we use a lot of Plaster Cornice ( crown molding )
This comes in lenghts of up to 6 m ( 18ft ) and comprises of a gypsum centre covered in paper.

The pieces are cut to size with a handsaw in a mitre box and then layed face down ready for adhesive. Adhesive is a compound just like setting compound only sets a lot harder and faster.

Andy runs the adhesive on with a steel trowel ( there is a knack and they make it look soooo easy )

aim for enough adhesive to get this effect. This saves a lot of finishing trouble and you know you got contact all the way.

and this is the preferred way to move cornice around. It's a little tricky at first and the longer lengths can be a problem.

yes Ken there are many profiles. This is just one. Plaster cornice was traditionally cast up on a mold and there are many places still doing this with some spectacular types available.

I've never seen stained cornice. I doubt if it would take it. ( it's cardboard covered the stuff I'm using and the older stuff is cast plaster )

I think his question was tongue-in-cheek.
Like a sponge, Jeff. Like a sponge...

I was a jokin!
Musta got lost in the overseas translation.
Just saw that type of install on some home show on TV.....thought it interresting.
Is it used mainly to matching existing details....for for new work?
Never saw anything like it around here...but it must be somewhere state side...ala...the TV show.
U guys have MDF crown......I can get the primed MDF in same profiles as pine or hardwood......for larger profiles...I'll usually go with the MDF when paint grade allows me. Usually cheaper.
How's that stuff compare to MDF....and/or....
How's it compare to paint grade wood...price wise?
Looks like the install would be a time/money saver...unless it's way trickier than it looks.
Ya think there'd be a steep learning curve?

Timber ( or MDF ) crown would be the exception rather than the rule down here. In fact I think you would have to have it run as it is not a stock item.
Price comparison..I think it would be cheaper. Both to buy and install. But I don't know what your costs are so I'm guessing.
Andy makes $40/ hour putting this stuff up. ( it's a lineal charge ). Material costs start at around 30 cents a foot ( your money ) and go up from there depending on the profile.
To learn. It's very straightforward. Just have to work fast as the adhesive doesn't muck around.
I'd say someone with an interest in and with a background in installing crown could learn it in a day.
I think there are cheap fares to Australia at the moment Jeff. Get yourself a ticket and come down for weekend. I'll arrange the accomodation and you can spend the day with Andy.
Probably be a tax deduction for you?
