Painting over Red Devil Onetime

[budest]

Hey guys,

Have noticed when painting emulsion over Onetime even after sanding the area I am getting Flash Through. Any ideas how to get around this? Here's a photo of a mist coat over Onetime. In another room I also encountered this with one mist coat & 3 normal coats later and I'm trying to avoid that here.

Could try a bit of Zinsser Coverstain, this should stop it coming through or a thinned coat of oil based undercoat.

It's a texture issue. Red Devil is very smooth. Use a couple of coats of cheap contract matt then sand lightly.
