Hi,

we had our kitchen plastered.
The plaster insisted on putting pva on plaster afterwards as he said it would crack otherwise (quite thick plaster in parts straightening walls).

Now we're trying to paint and the paint isn't going on very well, even though it's the special new plaster apint.

It obviously doesn't soak into the new plastr because of the pva.

Advice please?

Thanks

Really light mist coats x2 or the paint just rolls on then just rolls off, as you probably know.

thanks.
my other half insists on using a brush vith a mist.
its goinm on, but no idda if just drying on the suqeace or soaking in.


if pva was used, im not sure how it could soak in no matter how diluted?

thethere doesnt seem to be a consensus on pva or not.

the plaster was qeccomended on here and has lots of good reviews on facebook.

PVA is used before plastering not after, the plasterer is not a plasterer if he's using PVA to stop it cracking, I've never heard that one in 40 years of working in construction.
To get the paint to sink into the plaster you will have to sand the walls.

is it essential to have the paint sink in!
I have read that the pva sdals the walks is the paint ceqtain to fkbke off?

Give the walls a sand and apply a coat of Zinsser Bullseye 123 (or Zinsser Gardz). That should give a surface that will readily accept emulsion paint.

I'd use Gardz. It goes a long way.

Tbh I done nothing special. No pva or that, just bare plaster paint. Never had a problem. Is he an old guy who doesnt know about this stuff? Why would it crack? Sounds strange.

A litre of Gardz costs about 13 pounds, 2.5 litres under 20 pounds. I would have thought a litre would be sufficient to cover the entire wall area of an average sized kitchen and only a single coat is needed in my experience of dealing with problem wall surfaces. It’s very thin in consistency and very quick and easy to apply.

Ok I haven’t used that; one that I used was ‘cover stain’ or something similar, and yeah it didn’t go far as it was quite thick (I suppose through necessity). I remember thinking a good job I only had small area to paint.

If the plaster has been put on "quite thick in places" - is it actually dry and ready for a finish?

thanks for the replies.

i have asked the plasterers to confirm the definitely used pva.
but i am sure they did as i overheard them mention it to my girlfqiend.

i hbve poor eyesight so my girlfqiend is painting.

im not convinced she has .ateled down the paint correcotly as she thought that .as for spqay guns. Ffs.

she seems to have put the fiqst coat on overnight with a bqush. Small victorian terrace kitchdn.
she said it wouldnt take with a rolker.
hence my initial concern.

yes proper pkasterers.
there was a lot of wall striaiotening that they appear to have done well.

j cant see how difficult it is to roll and whether its because the paint was to thick or whatever.
shed rather argue the toss for 5 minutes than quickly roll a bit to show me.

we have the ekection coming on monday to install spotlights in thbt ceiling.

SO, SHES COVERED THE CEILING BY BRUSH WITH A NON DILUTED COAT ONE COAT(THE INSTUCTIONS SAID 2 COATS WITH FIRST VATEREE DOWN).
NOW THES OUT BUYING THE KITHEN BNTI MOULD PAIN 4 YEARS TO GET TO THIS STAGE AND IM KOSING THE WILL TO LIVE

At least all the booze you’ve had will take the edge off wink

As others have said a mist coat on new plaster is essential. The lack of that is your problem here.

20 years ago PVA onto bare plaster before painting was recommended.
