Painting over plastered wall

[scall11]

My plastered recommended the PVA option, but also said if you water down the emulsion 50/50, give it a couple of coats with that, then use the full emulsion, that should do the job just as well? Seems to be alright like.

A 1st coat of watered down emulsion worked fine on my newly plastered walls

Just to clarify, it's not the whole wall that is the problem, just where the new plaster meets up with the old bit that wasn't knocked out for the DPC to be done.

Sounds like the old plaster is reacting with the paint As has been stated before a coat of pva over the whole wall should help Also you could give the old plaster a sanding to remove any efforvesance and then pva and paint.

take your carpet off the stairs and get some red paint and paint them like in that advert on the TV.

pva is quite correct, carpenter 22 years and you get to know all the tricks of other tradies and that is one of many.
