I have hung plaster a few times with a mate who is a plasterer, however I have only hung plaster where cornice is used. So I am wondering if anyone can give me some advise on how to hang it without using cornice. So from my understanding this is the process (and a few questions I have): 1. Hang the ceiling first (do I need to leave a gap between the stud wall and ceiling sheet or do I cut the sheet so it is flush with the stud wall?) 2. Hang the top sheet, and butt this tight to the ceiling sheet. 3. Hang the bottom sheet, and butt it tight to the top sheet. So like a top down approach, rather that a bottom up approach. Is that the process or should I be doing something else? Also what happens is the gap between the bottom sheet and the floor is greater than 10mm, do I need to do something else or should I just use bigger skirting boards? Any information (good or bad) would be muchly appreciated. Thanks, Daryl Re: Square set cornice process 2Mar 30, 2014 9:06 pm Hi Daryl We did square set cornices a couple of months ago we did the plaster on the walls first (and told them we were doing square set) from what I understand they took the plaster further up the wall this they normally would. The ceiling fixers then arrived and they were surprised we were doing square set as opposed to shadow line due to cracking issues. I honestly has no idea square set was just held togther by tape but here's the thing if you already have the plaster on the wall then the plaster trowel is not hitting the ceiling causing cracks whilst trying to do the wall. 4 months on not one crack in the square set .....good luck with your build <!-- l --><a class="postlink-local" href="https://forum.homeone.com.au/viewtopic.php?t=62083">viewtopic.php?t=62083</a><!-- l --> Re: Square set cornice process 4Mar 31, 2014 6:07 pm Opps sorry we have plaster direct on brickwork over here not sheeting on walls - so our guys plastered our walls - sheeted the ceilings and then taped the ceiling to the plaster to create the square set <!-- l --><a class="postlink-local" href="https://forum.homeone.com.au/viewtopic.php?t=62083">viewtopic.php?t=62083</a><!-- l --> Re: Square set cornice process 6May 11, 2014 12:26 pm So how does square set get on when the walls that meet the ceiling are not load bearing walls ? particulary if you start walking around in the ceiling ? I had someone suggest that instead of using paper tape for the join between wall and ceiling, that you use the metal internal corner strips, as the paper tape won't last all that long. Putting up the ceiling first makes a huge amount of sense, as you can make the precision joins on the walls much easier than fitting the ceiling sheet later.

Re: Square set cornice process 7May 11, 2014 12:49 pm Hmmm... square set is a definite skill, and it's very easy to see any irregularities if it's not done properly. I'd say, if you're asking these questions, maybe it's best to get a pro? (I'm all for DIY, but in the long run you might have regrets.)

One of my neighbours house also does not have cornices (his house build in the 1990's) Neither houses show any sign of cracking at the wall/ceiling junction, however both these houses use post & beam (or stone & beam) construction with large roof timbers. They both have vaulted ceilings. I suspect that because large roof timbers were used, there has been no movement after the weight of the roofing was added. If your roof is engineered to use minimum sized timbers, such as is the case with gang nail timber trusses, then the truss manufacturers specify that there shall be provision made for vertical movement between the walls and the ceiling (assuming the ceiling is supported by the bottom chord of the truss). This means that in this case a shadow line joint should be made. There are proprietary plasterboard accessories available to help you make sharp clean shadow line joints. The walls and ceiling should not be taped together if there will be settlement of the roof/ceiling. Re: Square set cornice process 9May 11, 2014 6:44 pm Ceiling first regardless, then take the wall sheet up to it. Don't be too concerned how they come together as long as the gap is no more than 10mm. The sheet will span the gap above the internal walls.

I'd say, if you're asking these questions, maybe it's best to get a pro? (I'm all for DIY, but in the long run you might have regrets.) Which is why I decided on getting a pro to do it for me. I've done some gyprocking before, and just can't seem to do the join between two sheets smoothed out properly, so when it is painted there's a 150mm wide spot where the two sheets join up. If I did the whole house, I'm sure I'd be disappointed in the finish if I did it myself. Owner Building at Jimboomba Woods in Logan City Qld.
