Bubbles in paper joint tape on drywall, how to do it best?
Page 1 of 2
Applied a layer of putty, pressed in the paper tape, added another layer. Let it dry, sanded and noticed some bubbles in the joint tape. I've used some light hand putty and understand (aside from lacking technique) that it might not have been the optimal putty, so now I have medium wall putty yadayada. How do I best fix the bubbles that are there? Is it just a matter of tearing/sanding/ripping up the tape and some putty and redoing it with new tape, or is there another way? Do people use glue for the tape? If so, which one?
Best regards

Wet room adhesive is the most failsafe. Perhaps you can save the existing seams if you cut open the bubbles and apply adhesive, but of course, it depends on how extensive it is.
If there are smaller bubbles, just cut out and fill over.
There is no problem using medium.
But you can see if you can get Nordsjö Rems and joint. https://www.nordsjoprofessional.se/sv/produkter/nordsjo/professional-rems-och-skarv
Impossible to fail with, but one must consider that there's so much glue in it that it's hardly possible to sand.
The tape should not be glued.

They water down a medium, it looks way too thin. Then you're forced to use a spackle box.K Klicka said:
As an amateur, you should stick to a finer spackle with more adhesive.
And for God's sake, don't mess around with a 10cm putty knife.
Last summer, when I was plastering the walls in the kitchen, I embedded the strips with plaster just as you're supposed to. BUT almost all the strips became a bit wavy in the corners due to the moisture, and when I sanded, you could see that I was partially sanding the strip. It worked out fine since most of the strip was under the drywall, but I have to say it wasn't obvious to get it right.
Now it's time to plaster a new room, and I'm considering actually gluing them, and it seems to be wet room glue that's suitable, haven't seen anyone having problems with that?
The question is whether you can skip the first step with a plaster layer and glue it directly onto the boards? I've seen in another thread that someone did that? Or should you first apply a layer, wait an hour or so, and then glue? I suspect you might have to wait quite a while for the glue to dry, like 1 day or so?
Otherwise, of course, I can plaster the strips in again and see if they become a bit wavy.
The plaster I used was Byggmax fine plaster, which is supposed to be pretty okay.

I glued directly on the boards following the instructions from the paint shop. Used vårrumslim. Glued one evening and filled the next, but you can probably work more closely. It went smoothly and the result was good, and still is a couple of years later. Wooden house from 1929.
So you should let the putty with the tape dry first before applying the next layer? I got the impression that you should follow the instructions above but apply the second layer of putty right away. Then, when it has dried and shrunk, you apply another round of putty?
