hi, just a quick one. I have heard that some plasterers add PVA into there multi-finish mix and I was wondering why, and what the advantages/disadvantages of doing so are.
mixing PVA with multi-finish
- Thread starter standard
- Start date
I wouldn't it can make the mix very tacky and drag with the trowel.
I've heard people suggest it makes the mix last longer before drying and it helps toughen the mix up for delicate edges.
But not for me.

I wouldn't even think of doing it. As PBOD says, it'll ruin it. Try mixing some into bonding coat, it'll go like chewing gum, and you'll never spread it. It would be murder trying to spread multi finish with it in,,, it wouldn't work.

cheers for the advise. i will not bother trying it. thanks again
yeah don't do that!i've heard it said that a handfull (in a 30 ltr bucket full of skim/1 bag mix) of board adhesive slows things down a bit, from a trusted source so i tried it recently, didn't need to but in the name of science you understand, certainly didn't change the properties of the finish at all or shorten the length of the set but not convinced it lengthened it either, when is spoke to the guy again he said it would only add about 10 mins to it but that 10 mins could be all you need when tackling a large area, so it may have helped, easy to miss the extra 10 mins when you're on a set so it could have been better than normal.
I’ve also been told that peeing in it helps as well but I’ve not tried it; probably not a good idea to let the customer see you mixing up though

Haha!
Surely the paint would have trouble sticking if you did this also?

some interesting points for a student plasterer but I think I'l pass on that one.

maybe college should just sit you down in front of computers with a link to this forum then! we can't help on the practical side though.
we can't help on the practical side though.We haven't done any skimming for the last couple of weeks because of the weather so they say. So it has been a bit boring. Hopefully there will be some practical tomorrow.
Its good reading here. I didn't know what rendering was when I started. Still don't know all the terms . I suppose you cant learn everything with theory but theory does help. Looking at problems helps books can sometimes be a bit dry.
As trowelmonkey say a link could be a good idea. College reference site.
