Plasterboarding Walls

[Alson]

Hello guys,

My walls have Wattle/Laths.

I am considering just to remove the plaster only and nail/screw plasterboard over the Wattle/Laths.

Thin skim plaster on.

I am of the opinion that, leaving the Wattle/Laths will give a more solid backing.

Thanks for any advice.

You can if you want or remove.
Fit cross timbers will make it more solid. I don't think laths add much strength.
You can also board wall with wood ply sheets then plasterboard over as this makes fitting stuff to walls easy and adds strength.

Thank you for advice. I have removed the laths.

I tried to attach file, but could not.

Take a picture on a phone.
Just tap the symbol next to the camera symbol here.
Select picture and it will upload. If that was what you wanted to know

 

[Alson]

OK. Will do.

I have ordered 5.5 plywood as backing for the plasterboard. These will go horizontal. Plasterboard vertical.

I plan to use only a few screws to hold the plywood, initially, since longer screws will go through the plasterboard, plywood, and then the studs.

Any recommendations, please?.

Thank you.

OP,
From the info in your opening post there was no need to remove anything - plaster laths provide excellent strength to a partition.
Perhaps all you needed to do was skim over the existing surface.

In your last post:
You dont need to use a plywood backing for plasterboard. Standard plasterboard is 12.5mm.
Plasterboard over studding is fixed horizontally to the studs.

 

[Alson]

Ok.
I already paid for the plywood and planned to lay them horizontal, plasterboard vertical.
However, you suggest lay plasterboard horizontal.
Since they are all 8 x 4s, they cannot take the same run.
So, plywood will need to be vertical ?.

OP,
Read what I said: "You dont need to use plywood backing for plasterboard".

Thin ply is more likely to cause problems if it is allowed to bow between studs where it will prevent plasterboard fixing flat to studs .

Ply can be useful if you intend to hang heavy objects on the wall, for example a kitchen or workshop, but it would need to be thicker.

In most rooms it is not necessary.

OP,
To be useful: "to hang heavy objects" then, typically, ply comes in 25mm or sometimes 18mm.
Plasterboard is 12.5mm.
So, using ply and plasterboard would bring your finished surface out beyond the skirtings & architraves - it would cause further difficulties with any switches or outlets.
Its a very bad idea.

Of course, we don't yet know the thickness of the old L&P.

In the comprehensive renovation of an old house, I would not think that refitting or renewing skirting and architrave was an obstacle.

It's not a bad idea, but probably not necessary. Additional layers will reduce noise transmission, and I now favour adding mineral wool as well. Old L&P is thick and heavy, and very good at blocking noise.

Poster #12,
We dont need to "know the thickness of the old L&P" - plasterboard & skim will pull it out to fit.
The OP has not mentioned anything about "comprehensive renovation"? Why do you even mention it?
You dont think "that refitting or renewing skirting and architrave was an obstacle" - you are wrong again,
besides all the unnecessary work and expense, and maybe the OP's need to hire a joiner - there's also the possibility that your scheme for pulling out the wall might not allow any "refitting" with the original materials.
Your proposal is still a very bad idea.

Because I've looked at the picture.

There is no need for you to make a habit of belligerent hostility and intolerance.

Are you in pain?
