Spray painting interior walls
Discussion
Only problem with spraying is that once the electrician has second fixed everything you can't touch up the paint where his mucky hands have been, without seeing the touch up.
In all seriousness, you need to use very flat, contract emulsion for best results.
Only, this type of paint gives a cheap looking finish, and even then any touching in is never acceptable.
I much prefer a brush and roller (12" roller) and can paint a room this way not much slower than spraying.
Exterior rough cast though, is a different matter....

No!
No no no PVA!
PVA has no place in painting, ever.
The paint needs to soak into the plaster to aid adhesion for subsequent coats.
Well always done our properties in this manner with no fault, our decorator insists its done before painting fresh plaster but he is probably wrong as he has only been a professional decorator for 40 yrs. No no no PVA!

No pro worth his salt should PVA walls before painting, wallpapering possibly, but not painting.
One of the first things we're taught when starting C&G all those years ago.
PVA just means it takes longer and requires more paint to finish a wall as the first coat slides around and takes an age to dry.
Done well on new plaster, you can get a top finish just by using a mist coat although obviously a second coat is preferable.
Doesn't matter if your painter has 40 years or 4 years experience - shouldn't be using PVA!

Well he and my chap obviously went to different decorating schools, but trust me he pva's every fresh plastered wall and it never falls off and he uses far less paint.Everyone has different methods with the same end gain . TIGERSIX said:

Not wishing to labour the point, but have a look here - under 'How to use - limitations'.http://www.specifinder.com/brochures/3013_pdf6.pdf

Regardless of the limitations you point out .I too do not wish to labour a point, we have used this method for every property we have done with this guy for 40+ year to no detriment .Do you always believe what you read on the tin ?,and have you never experimented.http://www.specifinder.com/brochures/3013_pdf6.pdf

If its fresh plaster you might want to pva the plaster first so it isn't so porous fresh plaster soaks paint like its going outta fashion.

PVA definately has a place in painting. My mother needed to paint her ceiling due to nicotine staining. She did about 4 coats and it was still leeching through. One coat of PVA, and one coat of paint, and it was hidden.
I'll concede that it'll work for nicotine, and I'm guessing that that wasn't a bare plaster surface?
Tiger - A bit of googling will almost unanimously give results to the negative.
And no, I won't experiment with my customers money.
But if you and your deccy are happy, then that's fine by me

Std PVA will return to liquid if it's soaked in water but generally it's a water barrier.
I can't see it being remotely helpful to helping a new build dry out.
I can see that it might mean the walls absorb less paint but then so does a mist coat any benefit PVA gives must be very slight or it would be placed in a paint for new plaster by a manufacturer.
