Small area get 1 coat on you be home quicker! You know if it's gonna suck like a cheap hooker on how quick first coat dries! If it almost pulls in straight away then maybe 2 or 3 coats otherwise could craze

For small areas could you get away with using one thick coat of pva before skimming?

It took longer to type that & wait for an answer than it would've taken to apply 10 coats of diluted PVA!

What are you trying to save?

10 minutes?
99 pence?
100 calories?

Do you think professional spreads waste time diluting and applying multiple coats of PVA each day of their working lives, or do you think there might actually be a proper reason for doing it that way?

Diluting PVA helps it penetrate into the substrate better, instead of just forming a skin on the surface.
You may need more than one coat to control suction, if the substrate is very dry or porous.

In other words, if you want to be a chancer, then go ahead and put one coat of neat PVA on your wall/ceiling. OR.... just do it properly or you may end up wasting time, money and effort, because of iffy results.

Also, to be fair, I have to give BG some credit for trying to innovate what would have been a useful timesaving product if it had all worked out.

Better luck next time, BG.
It was an attempt to part punters with their money same as always with big buisness.
Snake oil salesmen the lot of them. Note how most products state use according to manufacturers instructions. PVA is one of the biggest cons going. Plain H2O does the same job.

That's what I said.
It worked, just not always. It should still be in production in my eyes.

Pva isn't a con, it's a time saver. One coat of diluted pva does what 10 coats of water would do

UniFinish is no longer made. If it was used correctly it was a lovely plaster to work with. Unfortunately the substrates which were plastered without cleaning the background down ie not removing dust and grease etc failed at times. High suction was also a big problem as well, we’ve all used our experience to give the substrate 2, 3 or 4 coats of pva to control the suction and this also caused issues.
I used to use it before I worked for BG but I used to go round, on high suction, and give the walls a coat of pva by brush to clean the surface and control the suction a bit.
The idea was good, and what customers were asking for, but the variations of what we are expected to skim over was to varied, at times on the same wall.

You're not going to believe this, but there's been someone all over social media and TPF, the past couple of years, trying to flog unnecessarily expensive tape with holes in it, just to stick beads on with.
Yes, but the idea is good and the product itself works. It was tested and adapted with the help of spreads before going to market and is now used on a daily basis by trades up an down the UK. Quality is remembered long after price is forgotten. (It's only been available to buy for the past seven months)
