Walls and Ceilings - Outer Drywall Corners??

Hey again guys! :)

Well, in our ongoing renos, I have a question about Drywall Corners. I purchased the metal beading with the paper edges. Now, I know you spread a little mud on the inner side of it to help it adhere to the drywall. My question is, do you still have to spread & sand a couple of coats of mortar over top of it to create a flush finish?

Cheers,
Cal :)

I haven't ever used the paper w/ the metal in it for the outside corners, I bought the metal bead for outside and the paper for the inside.

For the paper, I put mud up w/ a corner trowel and put the paper up, then I used my 6" straight to get all the excess mud out from under the paper corner bead. Once dry use a corner trowel. You will then have to make it wider so use a 6 or 8 or 10. I would also sand a little in between coats and be sure to put each coat on thin. If you don't, you'll have a heap of mud in the corner and you will see it after you paint. I have learned this the bad way!! HA I am no pro but have experience w/ this. Good Luck

You won't need the corner trowel/knife on an outside corner. After the corner bead is securely inplace, you will need a couple of coats of joint compound [not mortar] over it, sanding the final coat prior to primer.

Are you using the bullnose [rounded] corner bead?

If you are using tape on corner bead, use a lot of mud under it, not a little. Use all purpose mud to stick it on. Then coat it with mud on top. Use an 8 inch knife for the first coat then a 10 inch knife for the second and third coats.

Hey Guys!

As always, thanks for the quality feedback, it's a great help to this novice kid!!!!

Sorry, I always get my terms mixed up, as I said "mortar" ... when I meant Compound. I bought a tub (like a large margarine tub) of all purpose joint compound, so I will be making a start on the simple flat joints first, to see how I do.

Do you sand each coat, or just the final one once everything has had time to dry???

Thanks!
Cal :)

I think you are going to run out of mud pretty quickly. Go buy the 5 gal. bucket. I wouldn't sand in between but definitley scrape down any heavy spots or lap marks.

"Do you sand each coat, or just the final one once everything has had time to dry?"

If you do a decent job of applying the j/c, you only need to sand the final coat. As coops said, you should scrape down any ridges or high spots. You could sand them but scraping is usually easier/faster:D

If you are good, and do it right like a pro then yes, you can just sand the final coat! But I know I am not there yet. So I do scrape the ridges and what not but I also do a quick sand to smooth it out a bit. I started doing this on my last room project and it seems to help a lot.

If you do alot of this type of work it may be worth your while to purchase the hopper & corner roller to properly apply the paper faced bead. The hopper & roller will run you in the neighborhood of $175 but makes appling these beads a snap & are well worth the $$. Here's what they look like All-Wall.com - Drywall Tools Superstore Multi-Use Hopper Outside Corner Bead (http://www.all-wall.com/acatalog/Multi-Use_Hopper_Outside_Corner_Bead.html#a6935) If you look on e-bay you might find a set of these tools at a big discount & I wouldn't be afraid to buy them used, as they are virtually indestructable.:coffee:

Thanks for all your help guys! ... my first drywall/mudding/taping project is complete ... and I'm pleasantly surprised at how good the results are.

Cheers!! :)
