Please Help ME!!
I know this isn't really the right category, but I can't get a response in the plaster; maybe you all could help with my angles!!?? I am using bull nose corner bead to finish around a window. When I come to the 90 degree corners, the just don't come out right. There are gaps. What are the angles? I cut a 45 on each piece, but the angle is no where close to matching up. I assumed that since the angle is a 90 that two 45's would work. Please Help!
You can get a 2 way corner cap for those you know...pla-cor makes one kind..
Anyway you are most likely having a problem because you have the drywall coming right out to the corner, you need to trim those back about a 1/2 inch on each side.
It's either that or the corner isn't a 90, (check with your square) or you aren't cutting at a 45, or the planes aren't level. To make sure you have the 45 you can always put the bullnose over a 2x4 and cut through with a mitre saw... with it in position so it doesn't flatten out on you. (I'm assuming vinyl, don't do this if you are using metal)
I'm betting you have the proper set back at the corner.
