Paint drying too quickly?

[chriselevate]

After a fresh plaster skim I’ve used some contractors paint 9:1 with water and most coated the walls and ceiling.

Now I’m using Layland Brilliant White Matt emulsion on the ceiling and Valspar V700 Matt on the walls I can see the it’s leaving streaks where the roller has been.

Is it possible to do this job in this weather or not? Thanks for any help & advice you can give.

9:1 is very weak. You should probably go over it with 1:1 to get a more opaque undercoat.

9 parts paint and 1 part water is weak?
Because if the streaks I think I’m going to have to fine sand it and go again. You suggest neat this time? Thanks.

That's OK ( not 9 water)
