Plasterboard – which thickness?

I'll be dot and dabbing it onto brick, does it matter between 0.95 and 1.25cm thickness??

ta

no less than 12mm i would say.

What he said.

The 12.5mm is about £3.50 from Magnet for a 6'x3' sheet.

thanks chaps

12.5mm and use 8 by 4 sheets: The less joins the better! Offer up board and tap into place with a nice straight length of 4" by 2" on edge, that way it'll end up flat!

9.5 or 12.5 for dot and dab, take your pick .With brick you might want to put a couple of coats of pva on or a splash of water at the very least. the old victorian bricks can take up moisture very quick and they board adhesive sometimes does not bond real good. and maybe a slightly runnier mix if you are not building out much. and like chicken said use a straight edge. good luck

Deffo 12.5 for dot and dab. Magnet is cheap if you have an account, so is selco. Otherwise b&q. Avoid travis perkins and local merchants, they'll have your pants down.

Check the flatness of the walks beforehand. You'll probably need to build out in places to get it flat.
Use gyproc adhesive too, goes a lot further than the lafarge stuff. Usually about 2 boards to a bag. Make sure your edges are dead flat and tight, or it'll be hard to get a good plaster finish

12.5 MM and no other also use 8×4 or 9×4 depending on ceiling height. less joints the better

12.5mm for walls, 9.5mm is generally for ceilings

I'd use a foam backed plasterboard if you are dry lining, then spread it after taping the joints.

Why?

And nobody would ever use 3/8 board on ceilings!! Sagtastic and far more joints!!

9.5 is for quick patching up jobs. 15mm is best but hard to come by and very heavy handling

You old pro funky! 15mm 8×4's on your own!! On a ceiling! =250 pound you've been framed action!

You can do it if the ceiling is less than 9ft. I use a t shaped prop out of 3×2 at one end and 2 quick prop at the other end. Only with 12.5 though. I've Never put 15 mm on a ceiling!

go to buildbase for yor 8×4 s/e boards mate i pay £3.50 +vat avoid gtec boards shit 😕

I love the idea of a plasterer vanity searching for the word "plaster" on the forum 😉

My old pile (about 25% of it anyway 😉 :

Ah, the ol' Makita portable radio ………you're a proper builder Stoner – and no mistake 8)

You're not a proper builder unless you have a radio found in a skip!

whos done the boarding i would get the sack for that i take it its not your trade lol 😕

i would get the sack for that

That andyplasterer, is because you are not an "artist" …… unlike Stoner.

Stoner likes to express himself through his work………..the horizontally fixed boards – in place of the more "conventional" vertically fixed boards, represents the rebellious side of Stoner's character – a snub against authority and society's rigid and repressive protocols.

Whilst the slap-happy presentation of the joints, shows Stoner's creative flare and his devil-may-care reckless attitude to life.

Ignore the philistines Stoner………I felt strangely moved and I have to confess, really rather emotional, by this great piece of work……..it is indeed a veritable masterpiece – a gem, a flower, in the otherwise chaotic confusion which a building site symbolises.

BTW, which radio station do you listen to on your Makita radio ? ……. I find that Classic FM helps me to swing my hammer in a rather more creative manner.
