Hi all,

I'm going to be doing some painting soon on fresh plastered walls. They've been left for quite awhile so I plan to use sugar soap first to remove dirt then I was going to water-down the paint I plan to use. Once dry I'll give it a another full coat.

Does that sound ok?
I've herd a few people mention that using a PVA solution would be best, what do you think?
 
I seem to remember that we sealed the plaster on the walls in our extension with a watered down PVA solution before painting. I guess you could give it an undercoat with paint but it may take several coats before the plaster is saturated.
 
I wouldn't personally use PVA, if you google the subject you will find a lot of people have had problems with paint bubbling due to using PVA on the plaster.

I think to be on the safe side using a watered down coat of paint would be your best bet. Its what the paint manufacturers advise you to do and is far less likely to be problematic. The last thing you want is to have paint bubbling, as it then becomes a massive ball ache to sort out.
 
Yep as mentioned above dont bother with PVA, no need for it.

Just put a misscoat on (Watered down Emulsion pain) it will soak it up then you can apply as normal afterwards.

Like peter says apply a Mist coat. I would recommend you use vynl silk emulsion as it seals the wall much better. You can pick up a 5L tin of poor quality silk real cheap (like £5-10) from most large DIY stores like B n Q etc.

I did some painting on a fresh wall for my old man.

I got away with one coat of diluted (30%ish water) paint and then another coat of paint. It was however quite a strong colour.
 
Hi guys,
Thanks for replies.

You say 'emulsion' paint. That's a water-based paint right? It should say on the tin?
And terms like 'Matt' or 'silk' is the paint effect once on the wall?
Sorry to sound dumb.

Yes 'matt', 'silk' or 'soft sheen' applies to the finnish of the emulsion (waterbased) when dry, on the wall.

Yup, emulsion is water based.

Matt, silk and satin will be emulsion, but if its gloss then its usually oil based.

Thanks for reply,

That makes sense. So would I be right in saying 'matt' gives a more warmer feel whilst 'silk' a more colder?

What kind of roller do you think would be best to use guys after the walls are sealed? Firm or soft? I'm thinking firm. I just painted over artex ceiling where a soft roller was better for getting into the pattern.

The difference between the two is that 'matt' leaves a flat finnish, i.e. it is dull (like a blackboards texture) has no shine and 'silk' has a shiney glossy or glassy finnish. The 'softsheen' on the other hand leaves a sort of mixture of the two, not shiney but not flat either. I would just use a normal 9" soft or long haired roller as it holds more paint to work with.

When we did ours we popped to B&Q and picked up a massive vat of B&Q value white emulsion, added a small amount of water as it is pretty horible anyway and used this as a base coat. We've had no issues with bubling and the colour coats ontop always went on and covered fine.
 
You "size" the wall with a watered down coat of emulsion as a primer, then give it an undercoat with the mully & then a top coat, Just wait till it's properly dry between coats before applying the next.
Don't use PVA for ***** sake.
