Ive put one right before when the lot came off in sheets of hardwall. Its dampproofing so how can the floating set with no suction at all

I agree but as you say the spec. It had been chopped 1m by builder and was restricted with original cornice still up

of what malc ?with respect :RpS_blushing:

i would choose limelight. prickup, float and set.
thistle bonding scratched, hardwall and skim. i know bg does not recognize these base coats being mixed but it would work.
thistle universal you may be able to use this in 2 coats.

Done this before and used bonding, it is for low auction backgrounds, as long as the membrane is fixed tight you shouldn't have any problem. Would personally give it a scratch coat first and let it set before 2nd coat which also stiffens the membrane up.

The spec will be bonding. It will only work and have any hand of lasting if the background is flat and solidly fixed. Otherwise it'll fail long term.
It's a **** system tho

I used to do a bit of work for a preservation company, we always dabbed boards if we had the thickness, otherwise it was a bond and skim. Like everyone has said membrane must be fitted properly or its a nightmare

We did inside of a church a few years back were they wanted lime done over the membrane. Did a small sample for them but it cracked like mad as we told them it would. They ended up having to dot and dab and skim. The fella that did the dot and dab just put the babs were there was a fixing. Turned out a great job.
