Hi there,

I am a painter and decorator by trade with plastering and tiling skills.

When new plaster is first applied I always cover it with a layer of PVA first. Once this has dried I will apply the first coat and let that dry for 24 hrs. The second coat is then applied. Over the last however many years, this method has always produced a long lasting finish. Dulux is a good paint product but I am starting to favor some of the Crown products that are now being released.

If I can be of any help then please feel free to contact me.

I agree with the many responses on here, your painter isn't a painter, always always use a mist coat, I use a watered down emulsion mixed with PVA, allow to dry, then apply 2 coats which has always for me left a durable long standing finish

Hi I've been a professional painter for 30 years now and you never apply pva to new walls unless your wallpapering and the wallpaper manufacturer supply's you with a pva based primer,it's a simple process to paint a new plastered wall just follow the paint manufacturer specification which is on there product ether by calling them or via the internet as all the products are different

firstly i agree with pro finish decorating...your decorator is not a decorator.
you have to apply a mist coat to new plaster or bare plaster, 70% water 30% emulsion. you need to give it 24 hrs to dry before applying a full coat, good luck scraping it off.

Yes indeed good luck scraping it of maybe you could get the man who done the mistake to rectify it first choice and pro finish are spot on with there advice if your scraping it off yourself use a wide scraper and steady away try not to scar the new plaster when your done scraping you'll have to sand the edges off the paint so you don't see them when you reapply more paint
Good luck

Hi
The wall has to be able to breathe, use a 50% -50% water emulsion wait until dry then add x 2-3 topcoats, if you have a problem wall you can in some circumstances use a 5-8% thinned down oil based undercoat, wait until dry the add your top coats.

Allways apply a thin coat of Matt emulsion to bare plaster roughly 50/50 mix with water. Never used pva to do this, the problem you have is the neat paint has not penetrated the bare plaster and has just formed a skin on top so it's not adhered properly, with a bit of luck it will scrape off just be careful.

Hi
I agree with the other comments made. Sack your decorator. Have always done a mist coat first left to dry, then apply 2 coats top coats

First your decorator is not a decorator, don't let him do any more work,
that's my suggestion.
In places where it was very dusty, the paint is peeling off.
Dulux is a very high adhesive paint depending what type of Dulux Paint did you use? With time and temperature changing it could peel off more.
Try to scrape off the paint, if it goes off easily you are lucky.

Should always be mist coated, scrape back the flaky area's and apply a coat of zinsser followed by 2 coats of emulsion, allow the zinsser to dry fully approximately 45 mins to 60mins

Always apply a mist coat first, 50/50 water to emulsion and allow to dry for 24 hours before aplying two top coats with desired finish.

Agreed with everyone else here. Other than preferences on the mixture for your mist coat (personally use 50/50 only as it's an easier measure and has always worked for myself). Why someone would not mist it if they are supposed to be a decorator I don't know..... Try and save the plaster when scraping off as it will be time consuming enough doing that to also have to spend more time filling scars in the plaster from catching it with the scraper. I'd personally get the person who did it to remove and rectify the issue at no cost and then have someone else decorate for you.

No need to PVA an internal wall! 60/40 first coat then 2 good neat coats. If your painter don't wear whites then he is not a painter,I agree with the above scrape back what you and and undercoat damaged area with oil based no shlack based and float over it with filler but use a caulker or you will be there for hours with filling knife

Seems to be lot of people saying same thing but different views on pva being used etc!!!! I totally agree with other trades your first step should be to get rid of the cowboy not a decorator who applied the paint. Any specification new or old like me would recommend a mist coat applied followed by x2 coats of emulsion to ceilings and walls. Even spraying although the machine breaks the paint down I would not apply straight to new plaster. I hope your decorator has not touched anything else. Best thing he could do is admit he's a chancer not a decorator and gives decent tradesmen a bad name. I hope you sort it out if you need any advice please feel free to get in touch

Just reading this old post... Do decorators really pva and paint ?

Really ?!!!!!!

Seriously you dont ?

Ive heard of it for sealing before wallpapering. But paint and pva..?

Never use pva!!no need for it at all on internal walls!!its designed to seal surfaces!you need the paint to soak into the fresh plaster.
Always thin first coat to the guidelines on the tin..
Pva and paint dont mix!

Always on new plastered walls/ceilings apply a coat of contract paint,this will seal it for your choice of emulsion.

I nice mist coat or 2.
Let it dry out proper
Then 2 nice coats of too paints

Sometimes theres a problem with the walls or the mix in the plaster that the paint just doesn't want to adhere to ! Or salt in the walls pushing it's way out ! Or even condensation damp ! Its not always the decorater ! Number 1 never apply PVA to walls before a mist coat this seals the walls so there not breathable ! Number 2 the mist coat only needs a bit of water to allow the paint to flow as plaster sucks it in ! ( Paint is wet remember ! ) And you won't need to peel or scrape all the paint off just the loose areas then apply some peel stop over the affected areas then when it's dry skim some filler over the areas then rub down smooth when dry.

PVA forms a seal if applied to new plaster. It does not penetrate the fresh plaster so therefor when paint it applied it just sits on the surface and over time will flake. Never use PVA on fresh plastered walls. Mist coat followed by two normal coats.
