paper tape bubbles

josh6106

hey i've been using pro roc taping mud for my first coat on all flats, butts and corners, lately i've been getting some bubbles in my corners, only on the ceiling, any ideas, there is lots of mud behind the tape, so i'm not sure, i don't have a taper, i just use the corner box to coat the corner and tape it by hand , roll it and finish it with my finisher. thanks

I use ProRoc taping for putting on all my tapes and I don't have a problem with the tapes bubbling.

You use the corner box to run your mud before you tape by hand? Maybe you need to change your system and use at least a super taper. Keep your mud thin.

Maybe the ceiling is taking more time to dry than the walls, and when you think everything is dry ready for the next coat, the ceiling is still wet, thus creating bubbles when mudding over the tape.

Maybe try a little more pressure on your knife to make sure you push any air pockets out when your taping.

If i were you i would buy a banjo and learn how to use it. Then your dry tape problems will go away!

could be your mud is too thick and not flowing could be you are wiping to hard, could be not enough mud and whats on there is partially drys before it gets wiped down. If you are using a banjo perhaps when the tape is being pulled out you are not pulling straight out and forcing the mud off the tape as it is coming out I have seen beginners do this quite often. Maybe it could be the ceilings are not insulated and it is just freeze drying up there, all are possibilities, but one thing for certain it is something simple to figure out. If you are using a corner box with an angle head for applying mud to tape you will not get enough on the drywall, angle heads are designed for skimming. the reason you do not find air bubbles on the wall side is because it is recessed the top side is not so in theory the mud is just glazing the ceiling, that is what i think is happening. how are you verticals do they blister as well ? If glazing and then putting the tape in by hand I could see how the mud would dry before rolling.

thanks for the replys guys. i use the corner box with an applicator not the glazer to apply the mud before i tape by hand, than i roll and glaze. i've since did another house where i only had two bubbles, one on ceiling and wall, i think it happens when i get to the end of a bucket of mud and the mud is setting up in the bucket, maybe i should purchase one of those hand mixers or mashers to keep my mud thin, i think i'm going to purchase a banjo anyways, thought about the taper, but where i'm from everyone beleives in mesh tape on seams and butts, so i just flat box alll my seams first coat. thanks again guys. josh

I went through 2 pallets of proroc last year. Pain in the ass having to constantly remix. For the tape bubbles try to mix at lower rpms as not to create air bubbles in the mud. Do yourself a favor and switch to proform black.
