I'm installing an extra layer of drywall on the wall for tiling. It turned out that one drywall sheet extended over the entire stud behind it, which meant that the next drywall sheet didn't grip the stud on one side... Argh! :-/ Unfortunately, I can't take these down because I'm also gluing them as I screw them in.
The sheet that's only screwed on one edge has quite a bit of glue (PL 600) on the back and in the joint with the neighboring sheet, and it's not full-size but rather half, 236 x 58 cm. I put in a good amount of screws on the side that held.
What do you think... is it okay to tile on...?
 
Tough situation. I guess it's about a bathroom?
Removing the board doesn't seem to be an option. I would probably think it holds because gypsum is an inert material that doesn't move.
But if you're unlucky and it cracks at the joint, you'll probably have to pay for the repair yourself since it's not done properly. (I mean, the insurance company might give you problems.) But if you keep quiet and cross your fingers, it will probably be fine.
 
1) Is it not possible to reinforce the wall with an extra stud from the other side?

2) Put up a third layer of plaster on just this wall!

3) Tear down the whole wall and redo it :P

4) If the board is NOT located by the shower/bath, screw it in extensively and forget the mishap ::)
 
Tough situation. I assume it's about a bathroom?
No, it's a laundry room, so I guess it's not quite as sensitive.

Can't you reinforce the wall with an extra stud from the other side?
Unfortunately, it's closed unless I want to tear down the wall in the living room - but that would most likely cause protests primarily from the government... ;)

Put up a third layer of drywall on just this wall!
An option to definitely consider.

Tear down the whole wall and redo it.
Eh... an option that doesn't feel current :)

But if you keep quiet and cross your fingers, it should be fine.

If the board is NOT by the shower/bath, screw it tight and forget the blunder.
That's probably the direction I'm leaning toward anyway :P Otherwise, I think the strength shouldn't be too bad, it's rock solid now that the adhesive has set, and according to the description it should handle 125 kg/m2, so I'm keeping my fingers crossed....

Thanks for all the suggestions!
 
There are gypsum boards that you can put in the joint between the drywall panels. In this way, you at least lock the gypsum against each other. (I think you already did that with the glue... ;)) But I don't know if PL 600 is good enough, ??? PL400 I know works on gypsum.
