Sätta upp gipsskiva, skruva vart?

[loefgren]

Hello!

Beginner question. I am going to install 6mm renovation gypsum on this wall with existing gypsum board. I have bought 4x gypsum boards with 90 cm width.

The total thickness of both boards will be 2 cm.

Is it okay to place the screws on the 90 cm width and use plugs for 2 cm and drill through?

Or do I need to cut the boards to the same width (narrower) as the old boards so that they attach to the studs behind?

I will apply joint compound on top of the renovation gypsum afterwards.

Thanks!

Anton

Screw in the studs

Can you measure out where the studs are in the middle of each board, or do I have to snap each board to the right width? Then more boards are needed 😁

You can also glue them up.

Can also be glued up.

alright! But is the option to screw up with plugs through 2cm plasterboard stupid? In width with the boards. Should hold, right?

You can see where the screws are in the old boards, just mark the ceiling and floor with a strip of tape or something similar so you know where the studs are.

On a spackled board, you find the screws with a magnet.

It would be stupid

Thanks to all the pros! I'll send it up by marking the old beams. No need to screw in the outer edges of the plasterboard, it'll probably be fine.

Buy 12.5 mm gypsum instead, renovation gypsum is more expensive plus when you screw it, there will be a bulge on the gypsum.

You don't need to screw in the outer edges of the drywall, it should be fine

Ideally, you should screw in the edges and stagger the boards if you want to avoid cracking. What is your stud spacing? They don't look like 1200 boards in the picture.

Already purchased 90 width drywall which might have been a mistake. Will check the stud spacing. Maybe I can cut them to the correct width for the studs the wall is about 250 and I have 4 pieces of 90 width boards

Glue AND screw. Let the glue dry before you screw so the board doesn't bulge when you screw.

Find the studs and screw into them, there's also plaster in drywall to use.

A lot of glue, and just a few screws to hold them in place. The glue becomes stronger than the screws after a while.
Don't forget strips when you plaster the joints later.

Thanks! I'm at Bauhaus now and he suggested we cut each board to exact width and screw into the studs. A bit tempted to just glue the whole thing and screw where the studs are, mark out.
