Emulsioning new plaster

[David2749]

How many coats of 50:50 water/emulsion should be applied to new plaster

 

[Bonni]

None. You apply one coat of emulsion mixed with 10% water.

 

[David2749]

Oh, someone else of here told me it had to be 50:50 mix.
Its confusing

 

[Bonni]

The back the emulsion tin normally states 10%. I'm in the trade, definitely 10%.

 

[David2749]

Thank you, I did think 50:50 would be like painting water on the wall. I have read you can buy special type of substance that you paint on the wall.

Buy some contract Matt. 10 litres of Leyland trade for about 15 quid. 20% water will be fine!

A decorator I've known for years, in his own house used masonry white paint diluted at 10% as first coat.
He uses contract matt diluted 10% in customers homes.
Any thoughts?

Masonry paints contain fungicides that are not suitable inside.

Personally, I am not a fan of using contract paints as base coats. I would rather dilute "proper" emulsion (as per the manufacturer's instructions).

It is worth noting that the thinner the paint, the more the paint splatter when rolling. I try to stay clean when working. I walk in to the pub after a day of rolling walls looking as clean as I did when I turned up on site in the morning. I don't have "work clothes" other than when I know a job is going to be messy.

Why would this be a problem?
Are fungicides dangerous?
I think they are also found in bathroom and kitchens paint, or not?

You will find the back of a Leyland Trade will specify 10%. I don't it greatly matters, just as long as you get it to soak in.

I've just always stuck to adding a litre of water to a 10 litre tub.

I would say, that's good advice with the emulsion but I would have to look into the masonry idea.
