Why did the drywall tape fail in my garage? How can I fix it?

That was a bad tape job and if you are in a high humidity area it was doomed to fail. Get rid of all the paper tape. Use mesh tape as Traveler suggested. It does not require hotmud. Apply the mesh ...

Why did the drywall tape fail in my garage? How can I fix it?

Some of the other answers have hinted at this, but let me be explicit: There's no mud behind the tape. Paper drywall tape uses drywall mud (not to be confused with spackle) as the "glue" to ...

Why does my corner bead flange still show after multiple coats of drywall mud?

You appear to be approaching this in a scattershot manner and expecting too much, too soon. Odds are also great, given the foregoing, that you are overworking the mud trying to get it perfect (yes, I'...

Why does my corner bead flange still show after multiple coats of drywall mud?

One reason this can happen is when the corner bead isn't installed centered on the corner. If it's pulled too tightly to one side there's essentially a bulge at the flange. Put a straightedge on the ...

Why did the drywall tape fail in my garage? How can I fix it?

I don't see stains, but this usually indicates a moisture issue. Could be excessive humidity if there isn't a leak, given lack of stains. You may need more ventilation to resolve that. Perhaps just a ...

The best way to install the new sheets is to first remove any dried compound from the edge of the existing drywall that would interfere with the new sheet butting against the edge. Once the new sheet ...

re-tape when replacing drywall sheet

Use your drywall knife to scrape out anything loose. If you're familiar with drywall finishing you just treat it like a normal new butt joint and feather the repair to make it appear flat. Usually 12-...

Applying joint compound over old and dirty drywall

You don't even need to clean anything unless the soiling is greasy or would otherwise inhibit bonding. In fact, you risk damaging the unprotected paper surface of the drywall. I'd do your taping and ...

Can I apply joint compound over drywall primed with PVA?

You can absolutely mud over cured primer. (Or cured finish paint, for that matter.) Use all purpose mud (not a setting compound) and scuff the primer gently with 120 grit.

Do I need to tape inside corners where tile will be set on one wall?

Assuming the following scenario, I don't think taping offers much. If there's movement in the framing at the corner, tape isn't going to help. Your plan to caulk is probably fine. I'm not sure I'd use ...

Do I need to tape inside corners where tile will be set on one wall?

I usually do tape with fiber tape and thinset , this helps to lock everything together and the corner grout between the tiles won’t crack as easily or often.

Should taping prefill overlap be removed before taping?

I assume you are prefilling because the gap is too wide. Say we start from that if it be the case, otherwise there would be no need to prefill. If you are prefilling due to large gap between two ...

The outcome depends partly on how you handle the sheets. If you make clean, straight snaps there will be virtually no delamination of the paper face from the gypsum core. If there's curvature in the ...

It can be true depending on a few things. I would use a 20 min setting compound to fill all gaps/cracks/damaged areas. It will set by the time a room is done. Follow up with a tape and longer setting ...

Finishing a taper to butt seam is no more difficult than any other seam. Don't worry about it. (Especially if you've got a pro doing it.) Any paper that lifts should be removed.
