As far as I'm aware all the different PVA brands for plastering are the same , just different dilutions
( I know there's a waterproof version but discount this )
PVA is heavier than water
The thicker it is , the heavier it is
So if you measure a litre and weigh it you get a value per £ to compare different brands

Can anyone be arsed

My college teacher told me PVA is PVA the only difference in brands is if it has been cut with something or not

Waterproof pva seals well and don't go tacky again when water or wet plaster is applied. Cost twice as much as plastering PVA.
Method
Dilute waterproof pva to instructions and allow to dry. Bang a cheap plastering pva over and skim is good practice imo.

Or SPR

One coat. Dries quickly especially with fan on blowing air.
Another coat and when tacky plaster.

SBR is a styrene rubber like product I think? Same as she durable emulsions

Thoughts?

Everyone's missing the point
PVA is PVA
Different brand different dilutions
Price / weight / litre

The posh stuff diluted down to the same consistency

f**k it
I'll buy some Wickes , weight it and compare to posh stuff for you all lol
Can’t be the same then if they’re different dilution, as you put it!
