[Gibbo]

are they in the internals nick

 

[nickelarse]

yeah linear meters.

8 proper rooms and a couple of hallways. all new rooms

i dont know. just says on the paperwork i got through 75m (linear) expamet movement beads

 

[flynnyman]

So 15 expansion joints doesnt seem like a lot>

 

[nickelarse]

but what im saying is 60m per room, average 15m walls. why need them?

depends how its built but some jobs have them on all the reveals around windows also internal angles as someone mentioned.

bloody hell chaps... what the flippen eck you on about... INTERNAL MOVEMENT BEADS... are you nuts... the only time internal movement beads are used is when the structure it's self has them... I.E anything over a 6 meter run the movement joints are actually built into the structure... normal housing doesnt have them.

But listen chaps... this is what i was taught to do when i started... are you listening???? OK then i will tell you lot...
When floating with brownng, bonding, hardwall etc into an internal angle... when both elevations are nearly set... run your trowel up each wall so that you hit the substrate creating a gap ... then repeat on the opposite wall this creates a 2mm gap in the backing coat up the angle and will stop it splitting (or should do if not dried out to quick) from the hero https://en.tackfilm.se/?id=1264465979036RA23

i do cut the corners like u say... and its a school. dunno if that would make much difference

Try the expamet site for movement beads for internal angles, gives something like 5mm movement on each plane. Not sure on the spec but if my memory serves me well, and at my time of life thats a luxury, but I think an expansion bead should be every 4 or 5m with one placed over an area such as an expansion joint in the background surface. I will try and check the info but in all honesty the spec should this type of info.

I used some years ago, they were two stop beads attached together by some rubber or plastic

Similar thing here - https://www.marinoware.com/Products/lath.asp?prod=Accessories

Scroll down to the second bottom one

cheers nel.

it doesnt say if its for internal corners or in the middle of a wall. i just cant see it being used when the walls are only 15m2. i spoke to the qs today and he said he has no idea. so i think im just gonna have to put a figure on it high enough to cover my arse

M = linear metres M2 = square metres unless stated otherwise, they prob want you to mirror through any joints in the substructure through to your plastererd walls
