Fixing drywall tape

[Markk]

I purchased a house and in the garage the tape is peeling off the ceiling and walls. I pulled the tape off and it looks like when the did the ceiling, they skimmed coated it. To fix it, do I need to do anything special since its skimmed or do I just mud and tape it like normal and just even off the top coat with the skimmed level? Thanks

If the tape is easy to peel off then take it off and start over. You might want to sand down what is left before applying new mud.

I pulled it down already. Do I need to sand the mud off next to the seam to feather it into or can I just leave the squared edges and just mud up to them level?

as long as the existing mud is sound, leave it on, mud over top, lay your tape and you're good
if there's any loose mud, scrape it off.

Thanks, never messed with a wall or ceiling where someone actually took the time to skim coat it.

Keep enough mud underneath the new tape so it doesn't peel. Let tape dry. Add thin coat over tape with 6" knife and let dry. Coat evenly with 10" or 12" knife two or three more times as needed until desired result.

I use Lite Blue mud. The stuff in the green lid pale you'll be using a power sander to finish.

Chances are you will be higher then the skin coat if you do it right with three coats

Then just feather it out so it doesn't stand out as much?

I don't see why he's necessarily need to be much higher than the skim coat if the gap is exactly the size of the tape? I had something similar in our Master Bath when the heat pump drain pan leaked in the ceiling. Just lay down some mud, place tape on top of mud and put a layer or two over the top. The existing, dried compound in the joint acts as a screed for the tape knife on the new stuff.

He might want to go just slightly higher to give yourself some feathering for sanding but I wouldn't think it would be noticeable or even felt by hand if wants to keep it even.

I'm assuming a hack put up the tape originally because it is lifting. Along with that assumption is that there was only one coat put on which is the same level as the surrounding skin coat.
Op yes use 4,6,and then inch knives. Each coat should be thinner then the previous feathering out so you should barely have to sand and only after the last layer.

Fibafuse - it is a glass matt type tape that is supposed to be stronger than paper and you don't have to worry about having enough mud underneath

I picked up a roll on Amazon for $8 and it worked great - very pleased with it

Self adhesive drywall tape is great!

It is until the joint cracks. Self adhesive is only long lasting with hot mud. Paper tape w/premix.

I love this stuff. In my opinion, you still have to worry about enough mud underneath, but not as much. Like paper, you can over-scrape it too clean. But, it over-scrapes less, is easier to spot when you do over-scrape and it is easier to fix too!

It's not like body work where you build it up and sand it down. Keep the layers thin.

Thansk for the help. Ya, I dont know if this was a rehab house some did themselves or what, but most the seams and corner joints are bubbling. Figured Id start in the garage to get the rhythm back of mudding.

If it were me, I would sand it down, use the sticky drywall tape, then proceed to apply thin coats of drywall compound and feather it all out.

The fibafuse is pretty awesome, you can probably just feather out the seam once you tape and mud it again, though it will be physically raised more than the old surface. Just feather it out more if you are going for a smoother finish.
