When boarding out a wall, stud or dot and dab and the storey height is more than the board does anyone stagger the boards or just put the cut at the top, tape and joint finish.
Lucius
 
No lads i never have either but just noticed over here the Spanish do thought ide been doing it wrong all these years.
Lucius
 
Sounds right realy always do it on ceilings why not on walls just something ive never done.
Lucius.
 
The more i think about it your right Rich, i was thinking about the continous horizontal straight joint but youve always got a vertical one .
Lucius.
 
theres nothing to stop you starting half board with the cut, that way you can stagger the joint without putting the cut at the bottom..
make any sense?
stick em up brick pattern if that helps?
 
What about we look at it from a bricklaying point of view, when you are rendering we never wire over horizontal straight joints only vertical ones so why is boarding different ?
 
as rock hard solid said you should never have a four way joint, the same as ceilings.

stagger the joints however much over one full board it is. thing is Lucius instead of putting the cut at the top and then at the bottom of the next board, - its easier just to move the cut over half a board, similar to to building a brick wall, (or brick tiling), .
 
churchy baby if you need to rake a brick joint for wender do you just rake the horizontal ones?

what are you refering to with 'wiring over' church? expansion joints?

as for the stagger of boards...
i was always led to believe that the REASON boards need to be staggered is to stop cracks running.. BUT the reason cracks might appear in the first place might be due to 'joist twist' and if the only thing fixing a set of boards to the joist was the edges then that was almost encouraging failure.. stagger the boards and at least some of the joist is in the middle of a board where theres more strength..
although i could be talking absolute cowplop?
 
why doesnt the unstaggered join crack ???.....church sorry mate didnt get the last post .....which course would you rake for render would you do the bits in the middle (vertical ones) ?
 
I normally stagger the boards vertically on stairwell walls because you always seem to get cracks developing between floors.
 
;D well do you mean vertical joints where the brickwork hasnt been toothed in properly then? cover it in exmet?
it was the 'wiring over' bit i couldnt get.. i wouldnt have thought you'd fail to honour an expansion joint church... thats why i asked what you meant by wiring over?

perps..

no thats not an insult ;D
 
if you had commons and you wanted to wender them wouldnt you rake the joint instead of meshing it?
 
There called" perps" the vertical joints in brickwork and they are staggerd but if there is a straight vertical joint like if a window has been taken out and bricked back up without toothing in the brickwork you would put eml over the vertical joints no ?
 
All points taken boys, if it makes any differrence i did say a taped and joint finish so you would be trying to avoid as many butt joints as poss. When i worked in Aussi many years ago when they tacked a ceiling they would go up in the loft and stick a 6 inch length of board over but joints for added strength.
Lucius
 
Why would you have to have the bound edge spanning the joists on a ceiling but not on a wall? The yanks put the boards length ways when they do metal studs etc and they invented the 5h1t, I got pulled for putting boards long ways on a job once, just wondering. Easier to erect upright i know, but is it right??
 
Quite right Rock, i also dont always board upright it just depends on the wall as i said before with tape and jointing you try and avoid the butt joints.
Lucius.
 
The Yanks board horizontally for a couple of reasons. Most of their boarding is taped & jointed, and you will have less joints if you board horizontally so there will be less possibility of joints 'flashing' if the jointing isn't finished to a level 5 finish. Their drywall is available in sizes up to 24' in length, and even longer for special orders, plus they do 54" wide stuff too. They can therefore do most walls with just one horizontal joint. They also reckon it's better to hang horizontally because a standard sheet will span 5 studs at 2' centres instead of 3 studs if hung upright, giving more bracing to the construction. Saying that, most commercial work in the US is hung vertically.
