Plasterboard thickness

[Ron Lowe]

Hi, all.

Whilst there's major building work here, I've taken the opportunity to flood fill the place with co-ax from the head-end, and with cat6 from the network cabinet.

This has involved a certain amount of plasterboard cutting.

During patching, I've noticed that the original plasterboard seems to be an odd thickness. It's somewhere between 9.5 and 12.5. If I patch with

12.5, it sits noticably proud of the finished surface.

I guess I could use 9.5 and skim it to the finished level.

But any ideas why it seems to be non-standard?

Does it really matter?

It's probably the 'old' Imperial 1/2" board.

Don.

[Ron Lowe]

That was my thought too.

But I thought 12.5 was meant to be the same as 1/2 inch. ( basically a metricisation of 1/2 inch, like 9.5 was 3/8 )

Harmonisation without changing anything. Like 8' x 4' sheet material becoming 2440 x 1220mm.

Hmm. Perhaps with the change-nothing metricization, the tollerances changed enough to make things a bit off.

[Ron Lowe]

It does if I have tons of 12.5 mm board, and no 9.5!

[George]

So what are you going to do?

[Ron Lowe]

Probably purchase some 9.5 and skim. You seem rather unnecessarily unhelpfull and agrassive in your tone.

The reason I asked is because there may have been some other possibility I hadn't considered.

Something like: " Oh, in the '70s there was a fad for 11mm board. You can still get it here:

"

You asked why something is not standard anymore,and if it isn't then why worry and ask the silly question of why it isn't.

You ever thought of dot&dabbing the PB that needs to be raised out to bring it level? rather than filling it out.

Simple,yes.

In article , Ron Lowe scribeth thus

I've seen this before and its best to put the thinner stuff on then skim up to the required thickness....

Killfile you, for a start.

[George]

See ya.

If it's just for small patches perhaps Bear Claw clips might do the job . I haven't actually tried them but they look as though they line up the front surface rather than the back.
