Gaps or no gaps bttween plasterboard

[Server]

should I leave a small gap (say 1-2mm) between each plasterboard sheet or should it be as tight as I can get it to physically fit.

Not sure if after i have put the scrim on it, there needs to be a gap for the plaster to go in so it does not crack ?

Should have said, the board will be skimmed with plaster.

Should be a gap of between 3 & 5mm to allow the player to go through between the boards. Only problem with a 5mm gap is that the player can sag a bit so maybe not that bigger gap

Thats interesting.
I thought British gypsum spec is no gap.

Didn't know that.

As far as I know they used to spec a 5mm gap but changed it to be tight. Think it was back when they used hessian scrim and used to put an undercoat on the boards, but that's before my time

That's my understanding too

Max gap of 3mm.

Although if you can't read a tape measure dont panic you can buy 4" scrim.

I was always taught to nhave a gap... normally about a clout nails distance

I always leave about a 2mm gap.

Anything bigger than 3mm (usually boarded by someone else lol) is best done with bonding. I'm talking about 4-10mm gaps like builders boarding

How do you gap leavers leave a gap when a gap should be left by a leaver then?
On domestic when overboarding specially on Victorian when things can be running inches out its hard enough to cut it right let alone allow for a gap, they seem to make themselves on older properties. I've always thought tight is right?

Used to tack a couple of board nails around the board you are butting up to when we were in college.
But does it matter?

Does it b*ll***s

Plaster will fill it no matter how big..
They call me the board butcher.
If it fits in the scrim, it's bling

I can board like a builder sometimes @Nisus
