Ahh, methinks you are refering to the way the wall "sucks" the moisture out of the applied coat, then it falls off 'cos it is too dry?
yup! or if it doesnt crack and fall off, it dries too quickly and you cant get a finish on it.

what you have done by using pva 50/50 is kill the suction off completey you need a bit of suction to pull the render into the wall if i was you i would go and buy a couple of bags of bonding and use that its for low suction backgrounds regards steveI am a newbie to this site and plastering in general and I recently did a complete hallway/stairwell, only ever having done patch repairs before this.
I boxed in the stairwell drop and even boxed in some pipes and electrical conduit.
No-one told me you can't plaster over wood, but even plaster will stick when mixed with enough PVA glue...
However, I have a new problem someone here can help me with: Cement render to a bricked up doorway. I closed it up and the existing wall dressing is cement and plaster topcoat, so I thought I would give it a go.
PVA 50/50 to bare brick - leave to dry. Mix up 5/1 sand/cement. Sloppy mix. Like double cream but not as runny.
Applied to wall in 25mm coat. one hit. top to bottom. some places thicker others thinner. My brickwork not brilliant.
After about 30 minutes the whole lot fell off.
Mixed up new mix and ditto.
