   There will probably be 1 1/4 metal already up. Find it with a utility knife to see . Snap a chalk line on the edge of the metal and cut beside in scoring numerous times with the knife. You will proably use up one blade per stick. Take a nail puller bar and pry off the metal. The rounded corners will go right on., for they are bigger.

   Hi Tim,

   Thanks for the reply, but once I get the metal strip off the wall, I'm sure the drywall / gyprock would be all busted up ? So I'd have to cut the gyprock/drywall back a few inches and replace a larger strip  ? Whats your take ?

   I was talking about cutting all the way through the drywall with the knife. Your going to have to cut it back anyway . In order for bull nose to go on it has to be cut back, its not like normal metal. After the rock is cut all the way through , then its up to one of the other suggestions how you get it off. But the bottom line remains is that the rock will have to be cut back. Do it at 11/4 , and you have no rock to repair .

   I don't agree thatv you need to cut the gwb back 1-1/4" to install the rounded bead.  Actually, if you do cut off that much, to what will you attach the new radius corner bead?  Just pop if off the easiest way you can (experiment!) rasp the edge back, and install the new bead.  If you go the hot mud route, which is a good idea, be sure you don't mix more than you can use before it sets in the bucket.

   Don't forget that the base will not be reinstalled in the usual manner...there will be a gap behind the base at the corner if you try to 45* miter it.

   "'believe the house is finished with gyprock ( it was done in 1966 ),"

   How old are you? The metal should be 1 1/4, and it will proably be nailed at least every foot , because it was probably hung by carps. I sold it in those years .

   Now , he will tear things up with that many nails if he tries to get it off  with out first cutting beside the metal  to stop the shearing.

   Bullnose is sold in two inch , but if he would like,  he can fill back in 1/2 inch shy of the out side corner as it should be installed.  

   My point in the first place was to cut the metal loose with no resulting damage . Not that the new bull nose needed the 1 1/4, or should be installed over a that void , but it will work , as I have done it with hot mud underneath.  That is the fastest , surest way I know with out causing damage. If I thought  that it might be crimped metal , I would feel as you do.  But their isnt much chance of being that from  the year stated. Drywall was just making its entry into the marketing world. That was the time old houses were hung inside with it. That was a good business back then as vinyl siding was when it caught on. If I would have had a bazooka in those days ,...wow!!!

   I must be stoopid but last time I checked "corners of rooms" were mostly INSIDE corners, not outside corners.

   Wear gloves - metal cuts fingers.

   Save the utility blades and just tap the corner bead with a hammer to break it loose and form a crack at it's edge. (Light taps towards the corner from both sides) Then use a flat bar to get under it and start lifting the nails with the bead itself. If it's crimped on, or taped on, just pull it off.

   The "bullnose" corner bead is larger than the other, so you will need to get a taping knife and "chisel" the taping compound back far enough to bed the new corner bead. To finish, just apply mud as usual. Good luck!

   You'll also likely need to rasp down the corners after removing the metal outside corner bead because the inside of the radius on your rounded tape will contact the sharp corner holding it off the plane of the wall.   Essentially, you'll cut off the sharp outside corner to create a bevel across the previously square corner.  This too could be done with a sheetrock knife to hurry the process.  If your walls are textured, you'll need to scrape the texture back about 8" or so per side to give you room to transition the mud from your new corners.  You would also be time ahead if you use hot mud to set the tape instead of regular topping.  It's tougher, more resistant to cracks, and lets you get another coat on the same day.  Have fun.
