Should I still mist coat?

[dishman]

Had a room skimmed. After a few delays, I am finally getting around to painting it over 12 months later.


I am using Dulux Supermatt in white. I have read some apply this as is...without watering down.

But....I wanted to check...

With the plaster skim being fully dry....should I still mist coat the room? Then I assume maybe two proper coats.

Many Thanks...

I always mist coat on new plaster with a 50/50 mix.

the purpose of the mist coat is to soak into the surface, which, being bare, will be very absorbent. This will enable the later coats to adhere better.

BTW as it is (should be) fully dry by now, it won't need to dry out through the paint, so it isn't necesary to use Supermatt (it has the special property, as a non-vinyl paint, of being porous enough for new plaster to dry out through it). However it will do no harm. It isn't very durable.

I use Dulux, only need to water it down 1/4, much easier to manage without getting yourself and everything else covered in paint.
