I am drywalling my workshop space. I picked up some plastic Jchannel from Home Depot to put on the cut edge of the drywall where it "butts up" against the Jchannel for the steel ceiling


I have two questions here:

One...Is this the proper way to butt up against the steel?

Two....Am I supposed to mud over the Jchannel when i finish off the walls? I think i understand correctly that i use this vinyl Jchannel when terminating drywall against a non drywall surface is this correct? sorry for such a dumb question, but i searched all over the net last night and could not find the answer to this. Anyone have any pics or links?

Thank you..

Not going to insulated the building before the drywall?
Not sure why you would have a cut edge at the ceiling.
The top piece on the walls goes up first, any cut edge should be at the bottom.

Thanks... its insulated... this was a pic i had handy... So your saying put the "factory finished" edge to the top? I got that...

Do i put the vinyl J channel on the factory edge and do i then mud over it?

Thanks

j-channel doesnt require mud. You should just be able to slip it on and be done with it...the only thing is that you are placing it on a recessed edge if you are hanging you board horizontally. That edge is less than 1/2 inch and you will get a gap. also the recess drops down 2" and will stand out....the way I would finish it is with zip bead. It's easy to use and creates a perfect edge. you staple it on than mud it.
again ..no, you do not mud j.channel.

oops...didnt look hard enough,
measure from your ceiling to the topside of your loft. Rip your board to that measurement, cut and hang, cut side up. slip your j-bead on and you should be good.
looks like you're somewhere around 11' so in theory you could stack your board placing a rip on the bottom, around 3', stack your next full board, and then rip your top piece so to eliminate a seam above the landing.

i mud J channel and it works fine. they do not stock the zip bead and takes weeks to order and when doing special designs and accents with drywall you can mud it.

I wanted to attach an updated photo... Dont laugh at my temporary loft lighting...LOL...

I am confused when you say Rip the board? It is 81 inches from the loft floor to the ceiling. I planned on hanging the sheets Vertically.. So if i understand correctly drywall finisher, your saying to put the jchannel on the "cut" end and Dont mud it?
