Glue consumption - renovation plasterboard?

[andreas.mehlin]

I want to glue renovation gypsum boards to concrete walls.
I was thinking of using gypsum mortar on the slightly uneven wall, but on the other walls maybe mounting adhesive would work. If so, how much is needed for a 2500 x 1200 board?

Gypsum mortar seems to have a usage of 2-4kg per sqm, i.e., 6-12kg per board.

Not something I would recommend, better to let someone plaster the walls! Tried installing gypsum here, didn't turn out well, threw it out and had the walls plastered instead. It's hard to make them lie exactly flush, which makes them easy to break and I also didn't think they adhered properly. Is it a lättbetongshus?

I think you'll need 1 tube per 2400x1200. When I glued 2400x900, it took 2 tubes of construction adhesive for 3 boards. It's expensive. Use gypsum mortar and click on the boards, then spread with a 10 notched trowel.

It is an apartment. Some of the walls are blue concrete and some are regular concrete. Tried renovation wallpaper but was not satisfied with the result.

1 tube per sheet is about the same price as gypsum plaster. A tube like PL400/600 costs around 60 SEK. 25 kg of gypsum plaster is 179 SEK.

So, if you've tried with renovation wallpaper it sounds like you just need to plaster the walls? That's simpler than trying to glue up drywall sheets that might come loose later.

Well, or sure, all for plastering but I appreciated that it would take a lot of time and effort. I have now put up three sheets of Renoveringsgips. Managed to crack one sheet while carrying it. Will see the result tomorrow. Had to place some weights for tension to get the edges in completely. Used plaster mix

Almost faster to plaster...

Faster, I don't know...
You can put up a board in 5 minutes. An uneven wall needs to be plastered three times and sanded.
