double gypsum - 1st 26mm?

[Yrrol]

When everyone has persistently insisted on this magic of double gypsum, I thought there was a finished 26mm board, but now I suspect that people are placing two 13mm boards against each other.

Do you then glue between these layers?

 

[jeppeknaster]

If it is a regular stud wall or a solid wall, the boards are screwed with staggered joints. You can glue drywall to stone walls or other walls where screwing is not possible.

 

[Yrrol]

how do you cut drywall, do you need some super fancy (expensive) machine to get nice cuts or are there simple ways?

 

[Havsutsikt]

Gypsum boards are cut using a gypsum knife and a ruler/straightedge/board by making a cut through the paper on one side, creating a break line, and then snapping it with your hand so the board breaks at the cut. Then, you cut the paper on the other side from underneath when the board is broken. If you want an extra smooth edge, use a gypsum rasp or gypsum plane to even out the edge. For difficult cuts or cuts at various angles, use an old saw or a gypsum saw. Often, you'll need to carve a bit with an old knife to make it fit.

I watched some construction show a while ago, and they had a new tool for cutting drywall that, according to the carpenters, worked excellently. I can't remember what it looked like, but it made good cuts, and you could basically cut and control the tool however you wanted over the sheet. It looked a bit like using a jigsaw to zigzag around in a plywood sheet.

 

[Yrrol]

how sensitive is it to achieve perfect lines, or do you fill in the gaps before the next layer?

 

[Havsutsikt]

You don't use filler between the layers, but sure, if you've completely failed with the fit, you'll probably need to redo it and do it right, filler in between works, but I've never seen it, a bit amateurish if you ask me.

Check under montage in the far right field.


Also, note the instructions regarding the trimming of the boards, e.g., no cut edge above the corner of windows and door openings.

I watched some construction show a while ago, and a new tool for cutting drywall had come out, which according to carpenters worked superbly. I can't remember what it looked like, but it made good cuts and you could basically cut and steer the tool however you wanted over the board. It looked a bit like sawing with a jigsaw and maneuvering around a plywood board.

Blade Runner is the name of that tool.

ok, does it work well?

 

[it-snubben]

I have a Blade Runner and I think it's great.

Just draw out where to cut on the board and follow the line with the Blade Runner so the cardboard is cut on both sides directly.

 

[MathiasS]

A regular Talmeter is an excellent tool for plasterboard work. Sure, there are special tools intended for the purpose, but you already have the Talmeter in your pocket.

By the way, can we ask Yrrol where he intended to use double plasterboard? I only have double plasterboard on the floor and don't see anything magical about using it in other places?

 

[it-snubben]

I must add that, even though I like it, the Blade Runner falls into the category of "unnecessary" tool. And overpriced as well.

So, to agree with MathiasS, it's just as easy to use the knife and ruler you already have.

 

[barajag]

I have a Blade Runner and think it's awesome.

Just draw where it should be cut on the board and follow the line with the Blade Runner, and the plasterboard is cut on both sides directly.

Hi.

I have the gyproc "old" cutter and thought in the demonstration video that it seemed almost too easy. So I have a few questions.

Can you cut with it all the time, or does the gypsum dust become a problem?

What does it cost? Couldn't find any prices.

 

[byggare henke]

this is what I think
gipskniv is the best. blade-runner is for those who don't plaster so often.
because blade-runner gets problems with plaster getting stuck in the knife
