I took wrong advice to do something unnecessary or possibly bad by applying watered down PVA to new plaster (wish I'd found the advice here sooner) but it's done and now I want to know if this is really a disaster and something I should try to fix now? or if I can just leave the walls that are completed and finish the other rooms & walls using the more sensible method of watered down emulsion.

The plaster did have a chance to dry out for a couple of months before being PVA'd. On the walls + ceiling that have been painted, the paint has gone on very smoothly and evenly. I was actually really pleased because I thought the finish was very good.

Is it likely to peel off in a few months? Should I sand it all back down to the plaster now and start again? it would be a PITA to sand it all off as it'll be 4 walls and 2 ceilings that will have to be re done, if it's likely to be good for 2-3 years or more I might be happy to leave it as is.

You'll only likely have a problem when you come to redecorate in a few years time, when applying more emulsion, the old stuff will lift from the pva....or not if you are lucky..

I'd leave well enough alone for now..

If it ain't broke

If it looks okay and there are no obvious signs of defects I would say leave it. When you come to re decorate in the future there are products to help reduce the issues you could face.

For the other walls just do as advised on many posts. A mist coat to seal plaster and then the finish coat

Do a test wall first...if you dont have any problems do as the fellas say and leave well alone. (and sleep with your fingers crossed!)

I'd go with that as a sealant before re-decorating...

Thanks for all the replies, I feel a bit happier to leave this alone for now

Not sure, but I'd imagine that the PVA will have cured by the time you come to re-decorate anyway. When the time comes, I'd still be inclined to coat with Gardz as the other have mentioned already, just in case.
