Drywall corner bead and compound issue
by

My question is whether or not I have to sand away the progress I have compounded up to in order for the fix to be done. I am having issues with getting the joint compound to adhere to both a metal and especially vinyl outside corner beads. Which could have been prevented if I taped the corner before layering it up as much as I originally thought was the method. Should I attempt to stick with what I am doing? Or will this continue to fail and I need to chip away all progress to start anew? Or is there a way I can still attempt to tape and blend even though it is at a leveled mark of build up matching where I was patching? (Location is bathroom window outside corners)

If it's not adhering, no amount of compound it going to make it adhere. Chip it all away and start over. Check DIY network or you tube to see how to fix it properly.

It would help to have seen a picture . Did you replace a window. I am trying to figure out why you is used a Metal bead, usually those are used on wall corners for strength. Around windows usually is paper or mesh tape, because you can fold it for a tight joint. You may need to sand down. I wish you success!

I believe, I'm not a mudder, that there are mud compounds out there that have adhesive qualities that will stick like glue to your edges. Go to a good paint store and ask if they can help with the correct type of mud to adhere to the metal/vinyl joint. You just may have to chip away the old joint compound filler to get the correct mud to stick. Be sure to read directions as some will set up and harden in a matter of minutes so you need to be ready to slather it on and then smooth and later sand to the desired thickness and finish. Ask if after using the first coat, you can then put on the regular compound so you can work with it a bit longer to get the desired thickness and matching wall finish. If your outside, are you using stucco compound or regular drywall compound? Some compounds have plastic qualities in them to resist moisture from outside. Just as there are more than one car on the market, there are more than one mud compound on the market, and stucco compound also. I have had a lot of remodeling done and watch and listen and learn over the years. Unless you do it for a living, go slow and make sure to follow directions ans ask questions.

No matter what corner bead you use, it goes on before you start mudding. I hate to say it but you probably need to

No matter what type of corner bead you use, it goes on BEFORE you start mudding. That way, you can run the compound knife along the slighty raised outside edge of the corner bead and the drywall. You should build it up in several layers, using a wider knife each time. I hate to say it but you probably need to take off what you have applied and start over. Otherwise you are going to have a bigger mess on your hands.

After you put your bead up, you can run a thin line of mud. Then lightly press your paper to the thin mud and let that dry and cure about 24 hours. Then start your build up. Remember, you only have to sand your final coat just prior to painting.

If you re-read my post, I did not say anything about taping the corners. You said that your problem " could have been prevented if I taped the corner before layering it up..." My point was that it should not be necessary. I'm really not sure why you are having a problem unless you are applying too much compound and/or not letting it dry completely before applying the next coat. I have never had premixed compound fail to adhere to corner bead of any type except when I got impatient. The vinyl is a little thicker but not enough to make a difference. I don't think changing product in midstream is going to help. If you are more comfortable using metal bead go back to that and chalk it up to experience. Good luck with your project; sorry I can't be of more help.
