PVA costs £ 7 for 5 litres which makes 30 litres of wall primer. I think it was economics that caused this problem. Try buying paint for that price.

I have just finished a large contract with Labour supplied by the client. To avoid any problems, I insisted on the safest route I know. That is Super Leytex £ 17 for 15 litres watered down by 15% for the mist coat. This is cheap, easy to mix and is microporous so you can paint it onto dark (damp) plaster and the moisture can breathe out.

I have committed all sorts of sins with PVA in the past. Modern paints are very forgiving and I haven't had any complaints or comments as a result. I am happy with the above spec which seems foolproof.

wot are you on about?

Spottie, why dont you ask a grown up to explain it for you.

(Bathroom stripped back to old plaster and the odd bit of paint still attached)

Super-Latex all 4 walls and ceiling.

Then PVA the ceiling

Then paint ceiling with a durable matt topcoat.

The other walls are then to be tiled.

Sound sensible?

no

......because?

you are joking .......yes?

On this very thread you are posting on, it states quite clearly several times, that you dont mix pva with paint in any way. (makes it even worse doing this in a bathroom)


And look here for info on tiling and pva (i will presume super latex would be just as bad?)

Hmmm you're right. The amount of PVA mis-information is mind boggling. This recommendation came from a guy a leyland trade shop. The said the PVA would be for the ceiling only due to condensation - to form a barrier to moisture. But yes I've now seem many other posts stating never to do this, and paint peeling because of it. Like this one - http://www.ultimatehandyman.co.uk/forum ... t1358.html

Regarding the 'super-leytex' paint : http://www.leyland-paints.co.uk/datashe ... ion_DS.pdf

...looks like the 'super-leytex' has no relation to PVA. The plaster looks like it was never really painted with a thinned paint to start with, which is where I presume the recommendation to paint with this stuff came from 'suitable for new plaster'.

That said, because I'm tiling three walls, I've now come back to the opinion that I should just used BAL primer and that's it.

For the ceiling I'm now think the same thing, but without the PVA. A durable vinyl matt, rather than vinyl silk as the ceiling isn't perfect.

GUYS
ITS TOO EASY
SUPERMAT BY DULUX ITS MADE FOR NEW PLASTER!!!
PVA....NOWAY JOSE

No harm in mixing it with vinyl silk...I have done it loads of times on bear Artex that is nicotine stained (after a wuick once using with watered down bleach in the garden sprayer)...PVA will hold back stains in many cases..and theres no other option...well apart from Zinseer or oher specialist blocking paints...that stink to high heaven.

Oil baed undercoat works sometimes...not everytime.

That said...thats the only time PVA and paint share the same sentence in my book...and certainly not, never, as a pre mist coat..waste of time money and it will probably lead to the following paint flaking at some point.

I have always used the following system with new plaster

1 coat of Albany Supercover
De-nib
Fill / skim over any uneven areas
2 coats of the chosen emulsion

Albany Supercover is much like Dulux Supermatt, except cheaper. I pay around £30 for 12l. It will cover a newly plastered ceiling in 2 coats. Its also available in Magnolia, so ideal for new builds (where magnolia is the norm) as it only 2 coats are nessessary.

I sound like an albany salesman! lol

do you water down the first coat?

Haha and the DIYers still dnt get it once they have been told by a pro! I thought the saying goes if u can p*ss you can paint! Ovbiously not!!

Sounds about right to me..
