Slope Ceiling Join

[herds]

Alright guys.

After the boards are butted together along the join do you just run scrim tape and then skim?

Do you try and cut the plasterboard at an angle to reduce the gap?


Also, is it the same method for an outer join?

 

[casplas]

were there's a crack or joint it needs scrim including ceiling angles, unless you are not doing walls then get boards tight into angle and mushroom some gear into angles just before you skim ceiling, if your doing walls scrim angles shared 50/50 on ceiling and walls

depending on how good your boarding is you may want to roll the ceiling corners in as there is nothing worst than a wonky ceiling line

Rounded everytime without a doubt. I always dub them out first, nicer roll.

If your boarding ain't to good and your wanting a crisp straight ceiling line,fit a stop bead and work to that..:RpS_thumbup:..
.if its an outer join as you say, again use a stop bead and work to that .I'm assuming the angle is more than 90°?. You can get a 135° angle bead, but a stop end will do the job..:RpS_thumbup:

we would scrim the joint, then dub out with thistle bonding, run a mould over the bonding so that you have a good shape,once the bonding has set, skim the ceiling and rakes all in one.
if you just dub out in set , the set will sag and it will look a basket.

good idea using a mould... never thought of that

whats a mould

scrim it bond it bat knife it if you have one then skim comes out great as malc said if you try and round it with skim it looks naf

you can use anything that will give you the shape. we use a childs plastic plate, or a paint lid. this just hides the ceiling line,which is never straight on rake ceilings. once you have got the shape it is just straight forward skimming.

 

[ELplastering123]

just skim it never mind the bonding out.

 

[johniosaif]

Use the external scrim cut in 100 mm sections, little bonding or use a spat to square it..

 

[stuart23]

I prefer nice clean straight lines rather than curves. Spat as mentioned above is ideal for it.

 

[herds]

Ah ok thanks.

I didn't really want a curve, i wanted it to be straight. Spat = spatula?

 

[Arti]

I would chalk line the angle if you want it straight...............:RpS_thumbup:

Staple your scrim on before you form the curve, saves you doing it twice.

And I like to mix half bonding, half drywall. Easier to form and less suction when skimming.
