PVA or Emulsion as primer

nudger

I Have to paint a new build and have a few questions.

Have read on other forums that some say as a primer pva is the way to go and others say watered down matt emulsion.

So
The wall's and ceilings are skimmed, how long before painting?

Which, pva (watered down 1-5) or emulsion (watered down 20/30%) as a primer?

Are ceilings different to walls primer wise?

How many coats would be required, 1 good emulsion coat, and would you then do a pva coat?

Have used pva on old walls that have been painted many times before and have found that the new colour coat flew on.

I presume that you do ceilings first ,then walls, and then skirting boards.

On new stirting boards, do you go straight to undercoat or is there a priming stage.

Out side.

Have new plastered walls, what needs to be done before the new colour goes on, do they need to be sealed, what product?

This is a new job for me so would realy apriaciate advice, might get more work out of it, have done all my own house work before and people think I do a great job but this is for a customer with high standards, advise please.

ps Need advise soon, meeting on Monday.

Thanks.

20-30% watered down white emulsion paint is the way to go.:)

Thats for ceilings and walls too.

Thank's Paddy, what's the story outside, think this would be a high speck job so need an ace up the sleeve, sealers etc.
Thanks.

I agree with Paddy147 on emulsion as primer. We painted our entire house this year and that's what we used on new plaster. We used watered down emulsion on ceilings and walls. We let the plaster cure for 28 days before painting. I've heard you can do it sooner but we had the time so we waited 28 days.

We primed ceilings, walls and skirtings at the same time. We then painted the ceiling completely with 2 coats and let it dry. Then did 1st coat on walls and skirting, then cutting-in along bottom or wall, then top of wall, then top of skirting and around architrave. Repeat until you're happy. We did 2-3 coats depending on the colour chosen.

A good paint job uses as few coats as possible to achieve the best coverage.

Outside i'm sure it's rendered with a sand cement render rather than plaster. As far as i know this doesn't need to be sealed and can be painted on directly once it's cured.

for outside u can use water down exterior emulsion ( weathershield from dulux for example) as a primer
