Does Johnstone's stain block primer also work as a sealant?

    Does anyone now if this also works as a sealant? I have had to repair part of my ceiling after being flooded ( twice, the second time after i had repainted to fix the first time) . I repaired the ceiling with adhesive and it is ok. I am now going to use a stain killer/block to overpaint the water stains.

    The company whose shoddy work resulted in me being flooded twice have supplied Johnstones stain block primer. The blurb on the tin says its a stain blocker/primer but has no mention of sealant like many other stain killers have.

    As i will be repainting the ceiling with emulsion i would like the areas where i have used adhesive to be sealed so that there is no chance of the wet paint loosening the adhesive. Does anyone know if i need a sealant , would Johnstones stain block primer do the job and does it also work as a sealant?

    thanks.

    A stain block has to seal the surface , that's how it works.
