How to paint a newly plastered wall?

[nespressowoo]

Do we really need to water the first cost down with water?

Yes absolutely, 50/50 water and cheap emulsion. You'll ruin the finish otherwise

Definitely yes, the plaster needs sealing so a 50/50 water and emulsion. If this is not done then the paint job will not be great

Make sure it's not silk paint though otherwise it sort of forms a skin

You need to wait a week or so as well.

Have never done 50/50.
Just 1 coat of white. 2 coats in whatever colour is going on.
Did entire house like this. Never had an issue.

Yes I used to work for a paint company so undercoat or cheap emulsion . I didn't though I got decent paint and it looked great .

But it's true about waiting at least a week before painting.

Thanks, everyone! It's been well over a week since it's been plastered so will decorate on the weekend.

With the 50/50 paint to we need to wait until it's bone-dry to do the second coat?

We waited for the plaster to be completely dry and used 50% emulsion 50%water. It takes about an hour to dry.

A 50 50 mix of water and Dulux Trade Super Matte, covers new plaster very well.
