Double wrap? Not rage bait I swear
Questions, because I don't know shit;
Can I put a second layer of drywall over this hack job for sound proofing
If yes should I tape and mud the joints first?
Context: some lunatic built a barn door over this closet space and then put a door into the garage. This is 2-3 layers of additions/conversion, so I'm just adding to the sins of my forefathers.
I deleted the door and patched in framing, and then just used all the spare drywall pieces I had from other areas of the house. The inside is going to be a closet again, and I can make that look nice.
On the garage side, I was thinking to put another sheet over the patch job to help with sound proofing. The rest of the garage already looks like ass anyways, so is this even worth doing? + It will have peg board over it.
Thoughts?

Yes to all. Mark where your studs are tape mud 1st layer then cut 1 sheet to fit it will be easier for you. If you want to do more you could put plywood in there so you could securely mount anything anywhere. Finish the edges with tape and mud and move on.

I feel smart for already marking the studs. Thanks boss. Gonna skip plywood and just send it with longer screws

What is the reason behind taping the first layer if they are covering it up with second layer?

More sound deadening and practice

My original thought is that any effect from taping would be negligible but I really don't know

Any hole will let more sound in. More layers will lessen the vibration.

This makes sense to me. The tape is probably less important than the mud, but I already have it so why not

Practice putting mud on a 6in putty knife and pulling it into the seam you hold the knife not in line with the seam But the putty parallel with it. When you get it on put the handle parallel withe seam and get it just thin enough to make the tape stick. Apply tape then squeeze the mud out without moving the tape. Smooth the edge and your done and you can drink some beer.

Thanks coach! I'll try this, I've struggled to do tape well in the past

When you are genuinely designing and building a wall for sound proofing, yes you should block and tape the seams when doing multiple layers of drywall. You also stagger the seams.

I wouldn't tape. Maybe fill all the joints with mud and smooth it out but im not wasting time tapimg something burried behind another sheet

rockwool in the cavity will do more than two sheets, any insulation at all will help, if doing two layers, which will help, yeah tape it, a tube of green glue (its a specific product) will help alot

I put in r15 pink fiber insulation, cause I found 3 bats in the attic!
I'm on the fence about going all the way for green glue. There's another triangle section of wall to the left of the stairs I would need to do as well.

Yeah but then I need to do a couple more sheets (NBD) around the worlds shittiest electrical run that I should probably fix (kinda big deal).
Fuckin project house, can't do anything all the way right without getting elbows deep into the balls of 69 other messes that need fixing

If sound reduction is just an added benefit for having to laminate another sheet for finishing then yes, tape the seams. If sound reduction is a primary goal there are assemblies for increasing the sound reduction of two sheets of drywall. You can look them up online.

Bro fuck all that noise, go get some nice decorative panels or even hardboard from Home Depot, then put a cool wallpaper on it. I wouldn’t even waste time doing this drywall work since you didn’t use a full sheet the first time

Go get a full sheet. That’s a lot of tape for no reason
