This will have no impact on the chosen paint finish you apply over the primer be that a matt, eggshell or gloss for example, the chosen paint finish will determine the end result.

Isi it water based
No, The Johnstone's Trade Advanced Stain Block Primer is oil based
can this be used inside on ceilings and walls that are heavily nicotine stained. And can you emulsion over with ordinary matt emulsion
