I’ve got to price running 5 1/4 inch crown. The issue is that I’m going to be running it over metal lathe and plaster. It’s a pretty old house and finding studs is going to be catch as catch can. Am I better using glue and pinning the crown to the plaster with brads?
The plaster is in perfect shape just in case you were wondering.
Thanks

I did something similar a few months ago. Depends a lot on how it was plastered and when. On some stuff even a gun nail driven straight causes breakout. I used glue and Brad Nails. I cut and fit each piece, then glued it. I put it in place and Brad nailed it to hold until the glue set.
Might want to look at one of the PUR glue guns. You can get glues with varying set time. and, If i'm not mistaken, one that will not set until you apply pressure no matter how long you let it sit.
Took me at least double the time of a normal installation.
I like to install a nailer first. It sounds like more work but it will actually save you time in the long run.
rip a 2x4 down the middle with your saw set at your crown angle (usually 30 or 45 degrees) so you end up with two equal sized pieces. cut off a small length of crown to use as a gauge to determine where to put the nailer. find as many studs as you can and use lots of construction adhesive to put it up. pepper it with nails if you have to. Let the construction adhesive set overnite.
I like to put the nailer a little higher than the back of the crown to adjust for variations in the trim, maybe a quarter inch or so. It also lets you "roll" the ends of the crown for best fit.

Instead of using nails, the trim attaches to the wall with joint compound. I think they used this on a TOH project. The trim itself is foam, covered with a thin layer of plaster.

I do it Maverick's way with a nailer. One other thing, are the studs wood? Sometimes the studs for metal lath are steel, not the usual steel stud but the lathers steel stud. Now this would be rare in a home but not on a commercial job. You cannot nail into these studs. Screwing into them is only possible if they are predrilled, the stud is a good 1/16" thick and hard. I doubt this is the case in the old house, but if it is , there is a way around it. Cut your blocking to 12" lengths, apply subfloor adhesive , screw thru blocking into plaster with 1 5/8" laminating screws ( also called rock to rock screws). You have to wait at least 24 hrs before installing crown. I usually apply blocking on 3'-0" centers.

Maverick is right. Use the angled cant strip first. Attach with POL Glkue and a few nails to hold while the glue sets up and then you have ane even nailable surface ror attachment. Eaasier, Faster, Better.

Thats how I usually do it. If you haven't seen one already take a look at one of the PUR glue guns. Not the cheap model the industrial series. The model # escapes me. A little glue and a few brads and you won't be able to pry it off with a shale bar the next day.
Sounds interesting. What is PUR?
Hot glue?
