Installation layer on basement wall?

[FredrikR]

I was initially considering screwing first just to be able to adjust if something went wrong and also because screws are easy to get hold of. Since I wanted the slimmest air gap possible between the wall and the steel frame, I quickly realized that I would never be able to screw from the inside. Besides, this was the method the builder's merchant suggested. However, for me, there was only one option to make it stick, with pliers.
The upshot was that it went really fast, holds well, and in addition, it's super easy instead of holding everything and simultaneously trying to get a screw to drill and pull into the steel frame.

If you're careful from the start, choose the riveting pliers and you’ll have time for both...

I got the advice to screw from the 'outside', so there would be such a small difference in thickness where the screw heads went that it wouldn't be noticeable when plastering. Whether it works in practice, I don't know. But the pliers definitely look worth buying. Let's see if it can become a project thread when it kicks off.

I was advised to screw from the 'outside', as the difference in thickness where the screw heads ended up would be so small that it wouldn't be noticeable when sliced. Whether it works in practice, I don't know. But the pliers definitely seem worth buying. Let's see if it can become a project thread when it kicks off.

Yes, you should screw from the 'outside'. What I meant was that I couldn't reach to put the screw on the 'outside' on the inside of the rail since I only have 25-30mm to the leca wall. It might have been possible to screw 'from outside' on the outside of the rail and 'from inside' on the inside (towards the leca wall) of the rail. Crystal clear...? Hence the attempt with the pliers, which turned out well.

When building a 'regular' interior wall, this isn't a problem since you can screw 'from outside' on both sides of the rail.

Sure, you should screw from the "outside." What I meant was that I couldn't reach to place the screw on the "outside" on the inside of the rail since I only have 25-30mm to the leca wall. Of course, it could have been possible to screw "from the outside" on the outside of the rail and "from the inside" on the inside (toward the leca wall) of the rail. Crystal clear...?
That's why I tried with pliers, which worked out well.

When building a "regular" interior wall, this isn't a problem since you can screw "from the outside" on both sides of the rail.

The advice meant was the opposite, screw from the inside/where you can reach.
I'm going to build so little that the panels won't be noticeably affected.
