Newly Plastered Ceiling

[RickH]

Have a new plaster ceiling in klitchen, will leave 2 weeks then get it painted, the approach on Dulux website as below, but Painter is saying this is old way, and now should be all Vinyl matte.

>>>
Mix and Apply a Mist Coat
Create your mist coat using a standard contract matte emulsion (which is breathable) and water (Not Vinyl Matt) . A popular ratio is 70% paint to 30% water,

Top coat
Once the mist coat is fully dry, apply 2 coats of ‘Kitchen & Bathroom paint’


Is there any reason not to tell him to follow Dulux process?

All paints ( and building materials) have a data sheet (instructions) look online.
So each paint can have a slightly different application or preparation over dry surfaces like plaster.
Often it's 10% water added for first coat but I normally add a bit more. The retail Dulux with dog on can, has thixotropic agent in it for the DIY market and that's not great over plaster.
You can use a plaster sealer like gardz then emulsion over without thinning.
I use bathroom scales for thinning paint as it's easy to do.

I am thinking to use Trade white matt thinned for Mist coat, and probably Crowne Trade Clean Extreme for 2 top coats

 

[Wayners]

I think crown recommend using the clean extreme as a mist coat.
It's because durable emulsion don't like being applied to anything that is not a sealed surface.
You may end up using clean extreme as a mist coat over the vinyl matt

Why use a durable on the ceiling?
Will have around a 5% sheen as a durable.
You would be better with a lower sheen matt

Because it's a kitchen ..... and advice is 'kitchen & bathroom' paint (or the TRADE equivalent eg Clean Extreme) you are right I don't particularly want a sheen.
