The gaps are big compared with the material -- the plaster goes
right through it.

But the plaster only pushes up to the board, I shouldn't think
adheres so well.


The stuff is only slightly tacky anyway

Yes, I have actually used it somewhat.

to hold it in place until you cake it in plaster. The sticky
doesn't and isn't meant to form any part of the strength of the
finished plasterwork.


No, of course not. Having used both for a couple of houses, I
think that:

Jute does a better job, but takes longer to apply. Self-adhesive
scrim is far quicker and looks neater, but is only a "one sided"
fix, and not as good.

That said, the most important things for avoiding cracking are
suitable framework and fixing.
