Painting over Dulux Trade Supermatt, how long to wait?

[tai191]

Hi
Just painted kitchen walls that have been plastered now for a few weeks with Dulux Trade Supermatt. Watered down 3:1 paint to water.
We would like to paint over this with Crown Kitchen and Bathroom paint, the question is how long until we can safely paint over the Supermatt with no adverse affects?
Any advice welcome

Any time now. Don't forget to to thin down your topcoat 5%.

Is that a thin coat of the Crown Kitchen & Bathroom Matt Paint? so its ok to paint over the Dulux supermatt with "normal" paint almost straight away?

sorry meant to say thinned down, not thin!

Yes it'll be dry by now.

Allow 24 hours just to ensure the supermatt is fully dry, it can lift off in places if you paint over too quick with too many coats. New plaster, even a skim coat will still have a high moisture content if re-wetted.
